Akash Choudhuri
PhD candidate in Computer Science at the University of Iowa

I am a PhD candidate of Computer Science at The University of Iowa advised by Prof. Bijaya Adhikari. I also am a part of the Computational Epidemiology Research Group and the AlgoEpi Reading Group that discusses techniques and methods about algorithms, data mining, and Machine Learning that can be applied to problems related to the spread of infections.

My primary interests lie in the intersection of Machine Learning and Deep Learning with applications in Healthcare. I have been trying to construct predictive models that accurately estimate patient risk for different scenarios, like CDI incidence and MICU Transfer. I have been using various data mining methods and developing some of my own methods to extract knowledge to aid that task. My primary programming language is Python and I have good knowledge of Tensorflow and PySpark. I also have a fair bit of experience in model risk validation for Financial Institutions during my stint as a Consultant at Solytics Partners LTD

I was a serious Scrabble player as a kid, but now play it for fun. I am an avid reader of the non-fiction genre, with Jefferey Archer, Amitav Ghosh, and Saradindu Gangopadhyay being some of my favourite authors. I love to sing and used to have an acoustic music band called Tritiyo Purush back while I was pursuing my undergraduate degree. I also love to play table tennis and badminton (although I am not good at them).
