About Me

Hi I am Nayan, an undergraduate student studying Statistics, Computer Science and Mathematics at the University of Toronto. I am currently interning as a data scientist with the artificial intelligence team at Bell Canada, and working on better understanding human function learning using Gaussian processes at the Computational Cognition Lab supervised by Prof. Daphna Buchsbaum (UofT/Brown University) and Prof. Chris Lucas (University of Edinburgh). I am also a researcher at the ML Collective where I am working on Automated Machine Learning (AutoML), specifically projects pertaining to Neural Architecture Search.

I have previous experience briefly running monte-carlo simulations on the Niagara supercomputer cluster and working on the development of an R package for a journal manuscript on clinical trials under the supervision of Prof. Jessica Gronsbell (UofT) and Zack McCaw (Google). I was also a Research Assistant at the Intelligent Adaptive Interventions Research Group, where I conducted research on Statistical Inference for Multi-Armed Bandit Algorithms (RL) supervised by Prof. Joseph Jay Williams, and have worked on leveraging data to analyse political, social, and economic impact on social distancing behaviour in the United States supported by the University of Toronto COVID-19 Student Engagement Grant.

Projects

COVID-19 & Crime Dashboard

A dashboard focused on COVID-19 and US Crime data that makes future predictions on crime rates across Seven US Cities using Vector Auto Regressive Models and provide crime estimates before and after onset of the pandemic to gain insight into the effect of self-isolation measures on human behavior. This project won the Gold Prize for Best Dashboard based presentation out of 42 competing teams at the American Statistical Association Datafest.

DOT.

A binary classifier between open and closed eyes that seamlessly converts eye-blinking data into Morse code and finally speech, trained and presented at Hack The North 2019 (University of Waterloo). The project uses Keras with a Tensorflow backend to convert real-time blinking data to speech by translating data input into Morse code and further decrypting data into audio output and keystrokes.

Photography

I also like taking pictures, travelling and going on adventures. Here are some curated pictures from my Instagram.
