The Academic Me 

Hi, I am Arafat. I am a Computer and Cognitive Science PhD student at the University of Colorado Boulder, working with Associate Professor Tamara Sumner. I graduated from the University of Dhaka, Bangladesh with a Bachelor's and a Master's degree in Computer Science and Engineering. I have also earned a Master's degree in Computer Science at the University of Colorado Boulder.

My Research Interests

I am primarily interested in computational semantics and machine learning. I work on a set of semantics problems as well as their application in education. Although I have no research experience so far on this, I am really really really interested in understanding the human cognitive mechanisms underlying language comprehension and possible ways in which such mechanisms can be incorporated into computational models of semantics.
