About Me

I’m a Ph.D. student at MIT in the Clinical and Applied Machine Learning Group. I work on building machine learning models that are resilient to unreliable data. This interest map summarizes questions I care about.

I went to MIT for undergrad and majored in computer science with a concentration in South Asian studies. I’m also a former intern at Microsoft Research, Borealis AI, D.E. Shaw Research, Counsyl and Aetion. You can find my CV here or email me at divyas at mit dot edu, or both!

Research Interests

I’m interested in how we can deploy and develop machine learning models in the presence of unreliable data. Within this area, I’m interested in machine learning on noisy data, model uncertainty, and dataset shift. Right now, I’m curious about the value of data augmentation during inference.
