Graduate Teaching Assistant

Ruyuan Wan (

I am a first year PhD student in Computer Science, working in the area of Human-Computer Interaction at the EPOCH Research Lab. I earned my Master's degree in Data Science and a Bachelor's degree in Statistics from the University of Minnesota. I am interested in bridging Human-Computer Interaction (HCI) and Natural Language Processing (NLP) to develop Human-Centered AI. My current research focuses on mitigating online risks for youth and reducing algorithm biases in NLP tasks. In my free time, I enjoy hiking, rock climbing, and traveling.

Graduate Teaching Assistant

Ozioma Oguine (

I am a first year Computer Engineering Ph.D. student at EPOCH Research Lab. I obtained my bachelor's degree from the University of Abuja, Nigeria, where I majored in Computer Science. I employ my background in Computer Science, Modern Systems Design, and User-centered Computing to research technology-driven solutions that improve the quality of life for underrepresented groups. My favorite quote is, “Be the change you want to see in the world.” Most likely, you'll find me biking or at the gym.

Undergraduate Teaching Assistant

Lydia Csaszar (

I am an undergraduate earning degrees in Computational & Applied Mathematics and Computer Engineering. I am also a research assistant in the Computational Mechanics of Morphology at Notre Dame (CoMMaND) Lab in the AME department to develop software that can segment the tissue classes of the brain. Outside of class, I’m probably working on fixing computers (usually one of mine) or creating a new 3D print model to run on my printer. I'm excited to be a TA this semester. Feel free to contact me regarding any questions you might have.
