(Still avoiding mugshots!)

**About me, research interests, background etc.**

**Update:***Starting Fall 2018, I would be Institute Fellow at the Institute for Computational and Experimental Research in Mathematics (Brown University), working under the
mentorship of Prof. Regina Barzilay (CSAIL - Massachusetts Institute of Technology), splitting time between Cambridge and Providence. I would also be a researcher-in-residence for ICERM's Computer Vision program from Feb-May 2019.*

I am a PhD candidate with broad interests in Machine Learning. In particular, I have a predilection for (deep and otherwise) representation learning, structured prediction and general semi/weakly supervised learning. Currently, I have been exploring problems in the supervised learning of similarity and distance in low-shot regimes, as well as learning representations for combinatorial structures such as graphs and sets. I am interested in and seek inspiration from applications of machine learning in computer vision, and more recently, the physical sciences, especially in computational chemistry and physics. I also maintain an amateur interest in combinatorics and spectral graph theory.

For my research I consider myself very fortunate to be working under the supervision of Prof. Gregory Shakhnarovich at the **Toyota Technological Institute at Chicago**. I also work very closely with Prof.
Risi Kondor at the Departments of Statistics and Computer Science at **The University of Chicago** and Dr. Brian D. Nord at the **Kavli Institute for Cosmological Physics and Fermilab** (Group: Deep Skies Lab). During the course of my PhD, I also have had the unusual
and enriching experience of getting to design, prepare and teach a large graduate course in deep learning (under the tutelage of and with Prof. Kondor).
My most recent industrial research internship was at **NEC Labs America**, where I was mentored by Dr. Ryohei Fujimaki,
for work on robust optimization.

- + Some background:
- Prior to candidacy, I completed a MS (focusing on Machine Learning). Before that, in what now seems like a past life, I worked on problems in educational analytics, clustering and ensemble learning under the supervision of Professors Neil T. Heffernan and Gábor N. Sárközy earning another MS (in Computer Science, here's the proof!) with a thesis (Prof. Sonia Chernova was the reader) that presented a new clustering algorithm based on Szemerédi Regularity Lemma and also a method somewhat similar to mixture of experts using clustering for ensemble learning. Further afield, I worked in the industry in the signal processing domain (Application Specific Integrated Circuits) for roughly one year after acquiring an undergraduate degree in Electronics and Communications Engineering. While working I also helped my undergraduate advisor, Dr. (Mrs) K. R. Joshi, in teaching three senior year courses. During my undergrad, I worked on biometrics (face and speech recognition - using subspace projection methods for the former and dynamic programming for the latter). At the same time I also worked on blind source separation with applications to magnetic resonance image denoising.

**Teaching**

I have taught undergraduate and graduate courses at various points and served as teaching assistant for about a dozen CS/Math/EE courses. Once in a while I have won awards for the same, the most recent being the best TA award in the CS department of The University of Chicago and getting a commendation from the physical sciences division.
