welcome to my website

Hello, I am Anirban Sarkar currently a postdoctoral associate at MIT.

I am passionate about building systems that can perceive the world and behave in the wild, more like a human does, with explanations for the actions. Towards this goal, my research focuses on bridging the gap of human and machine intelligence through bringing inspiration from neuroscience to understand learning machines and facilitate improving the current state of interpretability and address the lack of robustness outside the training distribution.

Research Interests

Explainable, Trustworthy and Robust Artificial Intelligence and Causal Inference

About Me

I am currently affiliated with Sinha Lab for Developmental Research under Brain and Cognitive Sciences department at Massachusetts Institute of Technology. Here I am a postdoctoral associate and work closely with Dr. Xavier Boix on explainability under distribution shift.

Before that, I completed my Ph.D. from Computer Science & Engineering department, Indian Institute of Technology Hyderabad, under the guidance of Dr. Vineeth N Balasubramanian. As part of my Ph.D., I assisted the usability of DNNs through enhanced explanation to seamlessly operate in any diverse situation, that was reflected in exploring problems such as enhancing model robustness against unseen noise, adversarial as well as attributional attacks, and investigating more on self-explaining neural nets.
