For Computer Science student Tanisha Ravindran, her research journey began early. Joining the Dependable Data-Driven Discovery (D4) National Research program in her first year on campus, she now leads a team of undergraduate researchers as the only undergraduate mentor.
Her work investigates the reasoning capabilities and common pitfalls of large language models such as ChatGPT and Microsoft Copilot in solving integral calculus-based problems.
“I’ve always been fascinated by how technology can transform everyday life and solve meaningful problems,” Ravindran explained when asked why she chose to study computer science. “I’m deeply passionate about Artificial Intelligence and Machine Learning, and I believe that a strong foundation in Computer Science will help me excel in this field. I’m currently a Computer Science Honors student with a minor in Artificial Intelligence, and I’m excited to keep exploring how AI can create positive impacts beyond.”
She achieves this through her research, which involves studying why large language models frequently struggle with integral calculus, analyzing their reasoning processes, and exploring how they can better understand student learning and access in education.
Mentored by Dr. Wallapak Tavanapong, Professor of Computer Science, and collaborating with Dr. Eric Weber, Chair of the Mathematics Department, she’s already made great steps in her research. She’s earned the LAS Dean’s High Impact Research Award and presented her findings at the 2025 National Conference on Undergraduate Research – an experience she found to be “an unforgettable opportunity to share my passion for this work.”
“Receiving the LAS Dean’s High Impact Research Award was a huge honor, especially considering the number of incredible research projects happening within the College of Liberal Arts and Sciences,” she expressed. “As a sophomore, I am currently working alongside my Ph.D. mentor, Scott Song, and leading a small team of dedicated undergraduate researchers. This year, my goal is to submit our work to a computational research conference and hopefully publish a paper based on our findings.”
When she first received her acceptance offer to Iowa State, she says that “there was something about being a Cyclone that just felt right – like Iowa State was where I was meant to be.” Between Iowa State’s academics, community, and campus, in addition to the reputation of the Computer Science Program, she added that she made the decision to attend because, “I knew it would give me the right balance of challenge and opportunity to grow. The welcoming environment and the sense of belonging here truly made it feel like home from day one.”
“Iowa State is an amazing university with a beautiful campus that truly feels like home. Even after a year here, there are still parts of campus I haven’t explored yet!” she added.
For students considering Iowa State or a major in Computer Science, she had some advice: “For students thinking about majoring in Computer Science, I’d say it’s definitely challenging but incredibly rewarding. Academics are important, but they shouldn’t be your only focus. College gives you the chance to explore beyond the classroom and take advantage of opportunities that help you grow personally and professionally. It’s never too late to start — Computer Science is all about problem-solving and logical thinking. The best way to learn is by getting hands-on experience through your own projects, joining clubs, and participating in hackathons or events. And most importantly, you can find your people here. I’ve met some of the most supportive and inspiring friends, which has made my time here feel even more like home.”
