Krishn Bera

Cognitive Science PhD Student, Brown University


I am a third-year Ph.D. student in Cognitive Sciences at Brown University. My current work at the Neural Computation and Cognition Lab involves developing efficient and tractable Bayesian inference methods for cognitive process models such as drift-diffusion models. I am advised by Prof. Michael Frank.  My general interests lie in investigating the computational mechanisms underlying decision-making and learning in the human brain.
Previously, I graduated from IIIT-Hyderabad with B.Tech. in Computer Science and M.S. (research) in Computational Humanities. At IIIT, I was working at Cognitive Science Lab under the supervision of Prof. Bapi Raju. My work (thesis) involved empirical and computational investigation of motor skill learning in internally-guided sequencing.
