What You Need to Know About Becoming a Computer Science Major

Computer science majors are strong logical thinkers and problem solvers who use computers and computational processes to build websites, mine data and more.

Becoming a Computer Science Major

Getty Images

Students in a computer science major enter the dynamic world of technology, studying topics like artificial intelligence, software design and computer graphics. By the time majors complete their degrees, they will have the skills to examine complex problems with computer tools.

What Is a Computer Science Major?

Computer science is a major for problem-solving students who want to learn how to use computers and computational processes to build websites, program robots, mine data and more. Computer science majors may go on to master’s or doctorate programs in the field, and they can work in research and industry. Students will gain experience with the theory and practice of computer science as they explore algorithms, programming languages and operating systems, for example.

In classes, majors may apply their learning to topics like computational finance, robotics and network security. Undergraduates may be able to access internships and research opportunities through their programs.

Computer science major vs. computer engineering major: What’s the difference?

Computer science and computer engineering are separate computing majors that both study the hardware and software of computer systems. Computer science, with its deep foundation in mathematics, focuses on the theory behind programming, computation and operating systems.

Computer engineering is the study of engineering applied to computers and computer systems. While a computer engineering major is rooted in the practical use and development of computers, a computer science major teaches students how to design operating systems, for example, that run on the machines computer engineers create.

Common Coursework Computer Science Majors Can Expect

Computer science majors must study calculus to earn their degrees. Other relevant math courses include statistics and linear algebra. Introductory computer science classes cover topics like algorithm design, computer organization and abstract data types. After students develop a strong foundation in the major, they can move on to more complicated courses related to data visualization, neural networks and cryptography, among other subjects.

At some schools, students may choose to pursue either a Bachelor of Arts or a Bachelor of Science in computer science. The B.A. contains fewer required classes and may be more relevant for students who plan to work in another field after college. Many degree programs make it possible for students to combine computer science with another discipline, like architecture, electrical engineering or molecular biology. Students interested in research can seek out opportunities with faculty members, develop independent projects and look into relevant coursework.

How to Know if This Major Is the Right Fit for You

Strong logical thinkers excited by the idea of entering a challenging field might think about majoring in computer science. If you’d be eager to contribute to innovative research that boosts cybersecurity, creates virtual reality or trains machines, computer science may be the right fit for you.

Even if you don’t see yourself becoming a researcher, a computer science degree could still be a good choice. Career paths in the field span industries from fashion to information technology, with jobs for computer scientists available in data science, software engineering, application development and more. If you’re an adaptable problem solver or hope to become one, you may want to consider courses in computer science.

What Can I Do With a Computer Science Major?

Computer science has applications in all kinds of industries, including transportation, entertainment and medicine. With so many possible landing places, you can likely find your niche.

A major in computer science can open positions in data analytics, web development and consulting, for example, and jobs are available at companies ranging in size from small startups to large corporations. The major’s focus on programming skills prepares students to work as a computer system analyst, for example, who helps organizations use IT systems more efficiently. For a career path like this that works with more advanced systems, a student may benefit from earning a master's in computer science or a master's in computer information systems . Those interested in the systems used to store, organize and secure data can use their knowledge of programming languages to become a database administrator.

A computer science program can also prepare students to become information security analysts, who use software to protect organizations’ network security. A certification, like the CompTIA Security+ certification, can give prospective IT professionals’ resumes a boost, as it certifies you have the necessary skills to work in a cybersecurity career.

Those interested in becoming computer programmers can gain certifications in specific products and programming languages, and some companies require that computer programmers are certified in the areas in which they work, according to the Bureau of Labor Statistics. Those just entering the field may want to consider a program that doesn't have any prerequisites, such as the Certified Entry-Level Python Programmer or the C Programming Language Certified Associate Certification .

Students can also consider graduate study in the field. There are master’s options for those interested in industry positions as well as doctorate paths for those more likely to pursue research. When hiring a software developer – a role involving the planning and designing of software based on user needs – employers may prefer candidates who have a master’s degree.

Job opportunities in computer science are on the rise, so majors should have plenty of options. See the table below for jobs computer science majors can consider after earning a bachelor's or master's degree.

What Computer Science Majors Say

“I would say don't hesitate to take your first comp sci class. I began in my sophomore year, and even though many peers were ahead, the introductory course was interesting and manageable, and it is fun to tackle those projects. Give it a shot.”

– Cathy Chen , a junior at Colgate University, class of ‘25, a computer science and economics major, and a member of the Colgate Coder club.

“Being a computer science student can definitely be challenging at times, but it’s a worthwhile challenge. It’s a journey of exploring and problem solving. There’s a level of satisfaction that comes from exploring complex algorithms, developing innovative software, and understanding the intricate world of technology. Some advice I would give to new students is to not be afraid to explore new fields they’re interested in and to not be scared of making mistakes. I would also say to stay curious and keep exploring as technology is advancing every day. In my experience with student organizations like Women In Cybersecurity and Girls Who Code, these organizations are very helpful in encouraging minorities such as women to continue their studies in the field.”

– Daniyah Taimur , a junior at the University of Maryland, class of ‘25, a computer science and economics major, and a mentor of Girls Who Code UMD.

Computer Science

• Sample Assignments

In addition to the flexibility which comes from the breadth of the computer science discipline, the computer scientist has a wide range of career options. Generally, careers that focus on the development of applications and specialized software for business and scientific areas require the Bachelor of Science or Bachelor of Arts degree. With either degree, students are prepared for employment immediately after graduation. Students with an interest in the development of computer systems, including hardware and major software, will find that the Bachelor of Science degree provides a firm foundation for a career that may require a Master of Science degree and result in employment by a major computer manufacturer. A student hoping to perform advanced computing research or to be a university professor will find that the Ph.D. degree is essential.

The depth, breadth and flexibility of the computer science program includes the ability to apply classroom knowledge to real world projects as part of independent study, directed projects and regular classroom requirements. The following are a sampling of the recent projects students have been involved with

Video Game Creation

Students worked in groups for their final project to create a video game using Java Swing libraries. The project allowed them to apply their knowledge of data storage and organization to a real world software project, and produce readable documentation for a developer. Below are a couple of the projects: Snake, BlackJack and Pong:

Interactive Graphical User Interface

In a recent independent study, a senior computer science major developed an interactive graphical user interface (GUI) for molecular dynamics simulations. His GUI could visualize a molecule using three views while stepping through a simulation and checking results. The GUI was built with the TKInter libraries for Python, while the simulation was executed by the open source MDLab (mdlab.sourceforge.net) software.

Biology and the Game of Life

This course offered students a hands-on atmosphere for applied computing in the biological sciences and mathematics. By running simulations of biological cells using Conway’s Game of Life and the Cellular Potts Model (CPM), students study how the application of simple mathematical rules to behavioral entities result in patterns similar to those observed in nature. In the screenshots below, student projects captured foam bubble dispersion, cell sorting analogous to those in the eye, and the slime mould Dictyostelium Discoideum using CompuCell3D which runs the CPM:

Computer Architecture

Students explored the internal hardware of a computer and for their final project create a machine which can add two numbers using (shown below) breadboards, logic gates and LEDs. The LEDs illuminate to show the result of the addition.

Graphical User Interface Design

Students explored the various design issues which affect the appearance of a graphical user interface and provide the means by which a user may communicate with the underlying applications software, realizing that good design facilitates effective communication. Graphical user interface features such as mouse interaction, menus, dialog boxes, tool bars, error messaging and direct manipulation are evaluated and implemented.

In this particular assignment, students were asked to create simple word processing application in Java, using traditional GUI components, such as menus, dialog boxes, sliders, etc., from the Java Swing GUI widget toolkit.

Computer Graphics

Students were introduced to the theory and programming issues involved in rendering graphic images. Theory includes the physics of light and surfaces, surface illumination equations, and algorithms for rendering scenes using ray tracing. Visual surface algorithms, 3D viewing transformations and projections, anti-aliasing, 3D model transformation, illumination models, texture mapping, animation, and interactive graphic techniques are also presented.

In this assignment, students were asked to create an animation using a number of graphic objects, with one object demonstrating an attempt to model a real world object as accurately as possible. Object shape and surface properties, such as reflectance and texture, were chosen to realistically model the object. Another object had its surface appearance based at least partially upon the use of a two dimensional “texture” map. The project also demonstrates an object based animation as well as a camera based animation.

Evolutionary Computation

Students were encouraged to envision and implement projects in evolutionary computation that are of research level quality. Here is a sample student project, which after additional research and review led to a peer-reviewed publication at a major conference.

Project Title: Communication as a Model for Crossover in Genetic Algorithms

Abstract: We have created an evolutionary model of multiple ant colonies searching for a resource using swarm intelligence and a modified genetic algorithm. In place of the standard crossover we have employed a modified crossover which models communication; we call this a communicative GA (CGA). The communicative crossover operation sums up the moves of the most fit and least fit chromosome. The most frequent high move and low move are selected for altering. For each chromosome, the lowest move is changed into the highest fit chromosome’s most frequent allele. Statistics were recorded in each generation, including; max fitness, min fitness, the average fitness, the average number of generations it took to reach the resource, and the percent of variation of fitness. The statistics were compared to the same model implemented using a standard GA with a crossover.

Our model simulates N different ant colonies competing for one resource. We used N=4 colonies for our experiment. For illustrative purposes we have created a square shaped habitat. The ants’ path towards the resource originates from the colony and the ants may not go off the edge as seen in Figure 1. Six circular tiers were placed radiating outward from the resource representing some indicating factor from the resource. These tiers are used to calculate the fitness of each individual.

Creation of an Expert System

Students use an expert system shell to create expert systems in an area of their choice. Some of the most remarkable Expert Systems created include:

• Advising system for purchasing a boat
• What to do when a hurricane approaches
• Restaurant recommendation system
• Recommendation system for computer games
• Football head coach
• Academic Adviser
• Automobile troubleshooting system
• Recommendation system for music studio equipment
• Surf adviser
• Recommendation system where to spend your vacation

Automating Algae: Computer science capstone melds digital and physical skills

A team of four computer science graduate students are working with the Yogh Group , an energy technology company, to build a fully automated algae growth system called Algohelix. 

Ibrahim, who prefers to be referred to by his last name, said that at scale, Algohelix could provide biofuel, food, air-purification and even T-shirts through the production and processing of these tiny life-forms. 

The four master’s students: Ibrahim, Sudarshan Sridhar, Paul Hoffmann and Pooja Natarajan, who prefers to use her full name, will graduate after having worked on the project for an entire academic year. 

"It's like growing a bonsai plant inside of a house without human intervention," said capstone team lead Pooja Natarajan. 

An intensive problem 

Yogh Group CEO Levar Jackson said growing algae is currently an intensive process. 

"It's prohibitive to the locales and communities that would benefit from algae-derived products such as food and biofuel," he said. 

To solve this problem, the graduate students have worked since October to build a prototype of a system to manage and monitor oxygen, temperature, pH, water density and nutrition for spirulina, a form of algae that is commonly used as a source of plant protein. 

"Algae will easily die if there's some kind of contamination in the environment, so we want it to be a fully automated, enclosed system," Ibrahim said.

The team's largest challenges have been in building the bridge between hardware and software. Two members of the team, Hoffmann and Pooja Natarajan, have undergraduate experience with electrical engineering, which helped, but the complexity of automation led to additional difficulties. 

Smooth solutions

One of the primary elements of their project has been in trying to build a proportional-integral-derivative (PID) controller for the temperature in the tank. 

A PID uses feedback from sensors to determine how far away the conditions in a system are from optimal and adjust, in this case, how powerful the heating element is. 

It can be easy to overshoot the correction if the controller is not properly calibrated, which requires thoughtful coding and a deep understanding of how the hardware works. 

"We want to control the temperature as precisely as we can," Ibrahim said. "We don't want there to be any fluctuations, but to make it settle to a target smoothly, like when you take a deep breath or do yoga, with no hiccups or unnatural movements. Building that has been a challenge." 

A green future 

Pooja Natarajan said that working with living, growing organisms like algae is fascinating and that she hopes to continue working on growing other algae for use in biofuels or textiles. 

Ibrahim said that Jackson's vision is to grow algae at scale to get all of the benefits of the microorganisms through an integrated system of green energy, food, temperature regulation and more for hotels. 

"For now," Ibrahim said, "this is a proof of concept. Everything about it, and the future, excites me."

Three CEC students represent USC’s Goldwater Scholars honorees

Pictured (L-R): Caroline Rucker, Katelyn Wyandt, Jeremiah Tobin

Since 1989, the Barry Goldwater Scholarship and Excellence in Education Foundation has awarded more than 10,700 scholarships to students who intend to pursue research careers. Earlier this month, the foundation awarded 438 scholarships nationwide, and the University of South Carolina’s three recipients are all College of Engineering and Computing (CEC) students.

Biomedical engineering juniors Caroline Rucker and Jeremiah Tobin, and computer science and engineering junior Katelyn Wyandt, who are all students in the USC Honors College , were selected as Goldwater Scholars from an estimated pool of over 5,000 college sophomore and juniors. As a Goldwater scholar, each awardee will receive a $7,500 yearly scholarship and have access to a large network of leading researchers who can help provide mentorship and career opportunities.

“The fact that the CEC had three Goldwater Scholars in one year is a testament to our dedication to excellence in engineering education, research and mentorship. The success of our scholars reflects their considerable talent and our faculty's commitment to nurturing scientific innovators and future thought leaders,” says CEC Dean Hossein Haj-Hariri .

Caroline Rucker ‘25 Biomedical Engineering Hometown: Powhatan, Virgina

Rucker’s research experience started before she arrived in Columbia. During her senior year of high school, she worked in a laboratory at Virginia Commonwealth University (VCU) as part of an intensive research and mentorship program. Once at USC, she found a research mentor in Chemical Engineering and Biomedical Engineering Associate Professor Michael Gower .

“My research at VCU involved the use of lab-on-a-chip devices to examine the breast cancer tumor microenvironment,” Rucker says. “It was in the biomaterials realm, so when I came to USC and looked at the faculty research database, Dr. Gower was on my radar because he worked with cells, the immune response and biomaterials. “I eventually talked to a student who was working with him and the more I learned about Dr. Gower and his research, the more I was interested.”

Gower and Chastity Graham , national fellowships coordinator for the Honors College, both encouraged Rucker to apply to the Goldwater Scholars program. As Rucker learned about the prestige of the program, it was something she wanted to pursue.

“It’s an honor to be recognized alongside so many people who will be a part of the next generation of leaders in my field,” Rucker says. “Even just going through the application process allowed me to reflect on my interests and why I’m doing research.”

Rucker has worked with Gower on bio-inspired polymer particles for the treatment of chronic inflammation, which is considered a cause for a variety of health conditions. They have fabricated the particles and functionalized them with a phospholipid, which is the main component of the cell membrane and acts as a signal to enter cells.

“We've engineered particles that take advantage of a biological process to get into cells more readily. Our ultimate goal is to encapsulate anti-inflammatory drugs in the particles, which will help achieve a more targeted drug delivery,” Rucker says.

Rucker’s project associated with the Goldwater Scholars program will focus on using a synthetic phospholipid instead of one derived from a porcine (pig) brain.

“Using a synthetic phospholipid in our particles helps improve the viability of clinical translation because it eliminates the risks associated with having an animal derived substance in drug products,” Rucker says. “My research will compare the anti-inflammatory effects of the synthetic molecule to an animal-derived one to validate its efficacy.”

According to Gower, in addition to her scholarship, he has also been impressed by Rucker’s  stewardship to the CEC community. 

“For example, through volunteering at the Gamecock CommUnity Shop , Caroline has no doubt played a role in retaining students at our university and helping them thrive. I have enjoyed working with Caroline and look forward to her future accomplishments,” Gower says.

Rucker believes that her work and research as a Goldwater Scholar will have an impact in achieving her future goals of pursuing a Ph.D. in biomedical engineering and becoming a university professor and researcher in the immunoengineering field.

“Being named a Goldwater Scholar will certainly aid me in my path to attending graduate school and pursuing my chosen career,” Rucker says. “So far, it has helped me develop confidence in communicating my ideas and interests.”

Jeremiah Tobin ‘25 Biomedical Engineering Hometown: Greenville, South Carolina

Tobin first learned about the Goldwater Scholars program after fellow biomedical engineering student Shannon DePratter was one of four recipients from USC last year. But it was Mark Uline , chair of the Department of Biomedical Engineering, who encouraged him to apply because he believed his research was interesting and that he would be a strong candidate.

“Being a Goldwater scholar is a validation that what I do matters and is interesting and makes me feel good about my work and research,” Tobin says. “It gives me more inspiration to go to grad school and continue pursuing my research, knowing that there are people who care about what I’m doing.”

According to Tobin, he chose to major in biomedical engineering because he always enjoyed math, chemistry and physics courses. But his inspiration to pursue research was a course taught by Uline that focused on cell molecular biology for biomedical engineers. It was also where Tobin first met Uline and how he eventually began working with him on research projects. 

“We learned about all the different components of the cell and basic thermodynamics, and it’s still my favorite class to this day,” Tobin says. “We also did Michaelis-Menten kinetics, which is using math to predict how enzymes work, and the biggest inspiration for my current work.”

Tobin’s current research focuses on biophysical modeling, which could have various applications in immunology. Instead of biology research, which examines organisms and cells with different chemicals, biophysical modeling takes chemistry and physics principles, mathematics, and statistical mechanics and uses them to better understand its biology and how they work. The Goldwater Scholars funding will support Tobin’s research in modeling immunosensor proteins in the aorta.

“I’m particularly looking at inflammasomes, which are basically signaling platforms that cause inflammation,” Tobin says. “We're doing modeling and working with researchers at the USC School of Medicine on some experimental work. It’s a new immunology, and I think there's more that can be done with immune responses.” 

Tobin has worked with Uline for nearly two years, and he added that working with him has been his favorite part of attending USC.

“Jeremiah is one of the most talented young researchers that I have ever worked with, but what really makes him special is his attitude and inquisitive nature,” Uline says. “I am lucky to work with him, and he is going to continue to grow into a truly special engineering scientist.”

Tobin plans to earn a Ph.D. in biomedical engineering before working in research and development in the immunology field. He believes that being a Goldwater scholar will be helpful for choosing a graduate program based on his current research. 

“I enjoy and am passionate about the work and research I’m doing as well as its application and importance,” Tobin says. “Hopefully with the Goldwater scholarship, it will allow my research to have an immediate impact at a grad school instead of building something from the start.” 

Katelyn Wyandt ‘25 Computer Science and Engineering Hometown: Summerville, South Carolina

As a freshman, Wyandt was interested in computational neuroscience research. Even though she decided not to pursue this area, it allowed her to meet biochemistry and molecular biology major Emma Mason. They remained in touch and after Mason was named a Goldwater Scholar last year, she encouraged Wyandt to apply.

“It's a big honor to be a Goldwater Scholar. For me, it means that I have potential and people are willing to take a chance to give me the scholarship and believe that I can make a difference in research,” Wyandt says.

Wyandt’s research area is human-computer interactions, which focuses on the designing, implementing and evaluating the interactive interfaces used by humans and computers. While struggling to find a new research area, she knew she wanted research that combined her creative side with computer science. Then she found Integrated Information Technology Associate Professor Dezhi Wu and her research in human-computer interactions.

“I googled, 'How can I combine computer science with art or design’ and human-computer interactions was one of the results. After looking at some faculty research, I emailed Dr. Wu and told her I would love to join her lab to learn more,” Wyandt says.

Wyandt’s research will examine how people interact with technology and improve those interactions, specifically in the accessibility realm for education. She previously worked on the designing and testing of a multimodal digital learning platform, which considers more than one learning style and mode.

“While doing the usability testing, I noticed that in the design we didn’t consider those with ADHD because they had a unique interaction with the platform,” Wyandt says. “That began my foray into how people with ADHD interacted with our platform and the larger question of how to design educational learning platforms and technologies that are more inclusive of different learning experiences.”

According to Wyandt, she was the first freshman to join Wu’s HI3 Tech Lab . While her initial responsibilities included data analysis and literature reviews, she has become more involved in research projects. As her technical skills have increased, she has been exposed to more research communities.

“Katelyn is an amazing undergraduate scholar in my lab. Her scholarly development has been remarkable with her curiosity, passion and dedication,” Wu says. “I am immensely proud of her research accomplishments, which include two published articles as my co-author and one ongoing research project that she serves as a leading author, making her stand out among undergraduate students on campus and nationally.”

Wyandt plans to pursue a Ph.D. in human-centered design and engineering and aims to use the Goldwater Scholars program to deepen her research experiences.

“There’s an entire community of Goldwater scholars, and I’ve already met another scholar from this year who reached out and wanted to connect because they also do human-computer interactions research,” Wyandt says. “Receiving the Goldwater scholarship gives me a great launchpad and more confidence to apply to grad schools.”
