My CV often gets outdated, please email me for an up to date CV.

I received my undergraduate degree in Computer Engineering and Applied Mathematics under the guidance of Benjamin Snyder; Graduate Degree in Computer Science under the guidance of Robert Nowak and Rebecca Willett -from the University of Wisconsin-Madison. From 2017-2023, I was employed by Amazon under the supervision of Daniel Marcu, as a scientist to work on Amazon and Alexa search.

In July 2022, I decided to switch focus from machine learning and pursue a doctoral degree in theoretical computer science under the supervision of Graham Cormode at the University of Warwick. I was awarded the Chancellors International Scholarship, which supports my doctoral studies.

Everything I write here reflects my own thoughts and not of the people or companies I’ve worked with. My thoughts often mimick those of Eric Idle: “Bally Jerry pranged his kite right in the how’s-your-father; hairy blighter, dicky-birded, feathered back on his sammy, took a waspy, flipped over on his Betty Harpers and caught his can in the Bertie.”

Select Projects

NEXT is a computational framework and open-source machine learning system that simplifies the deployment and evaluation of active learning algorithms that use human feedback, e.g. from Mechanical Turk. The system is optimized for the real-time computational demands of active learning algorithms and built to scale to handle a crowd of workers any size. The system is for active learning researchers as well as practitioners who want to collect data adaptively.
