About Me

Hi! I'm Divyansha, a Ph.D. student in Machine Learning at the University of Pennsylvania, Institute of Technology, where I am fortunate enough to be advised by Prof. Eva Dyer. My main areas of interest are graph machine learning and neuro-inspired AI. My current research focuses on developing scalable frameworks for multi-graph pre-training and new methods for representation learning, particularly in domains with complex and unstructured data that challenge conventional approaches. I’m passionate about figuring out how the brain works and what makes it tick. I believe that by understanding the brain, we can unlock new insights for science and AI. If you are interested in collaborating, feel free to reach out!
