I’m a Ph.D student in Data Science at Worcester Polytechnic Institute studying machine learning for sequential data, advised by Prof. Elke Rundensteiner and Prof. Xiangnan Kong and collaborating with Cansu Sen in the Data Science Research Group.

Research objectives

My high-level interest is in mental models and their role in Artificial Intelligence. I am particularly interested in how we learn and curate our mental models and would eventually like to approach this representation learning problem through the lense of early childhood development. During my PhD so far, my research has involved the combination of Recurrent Neural Networks and some Reinforcement Learning techniques (which together loosely emulate human decision making). I have so far applied these techniques on modeling clinical decision making scenarios with high levels of uncertainty: noisy sensors, irregular multivariate time series, and early classification. My current trajectory is towards Model-Based Reinforcement Learning to focus more on computational mental models.

Education

Personal

In my spare time, I enjoy rock climbing, cycling, reading (fantasy, science fiction, science fact), and music (I play guitar/violin and listen mainly to folk and indie rock).
