About Me

I work on designing and understanding machine learning algorithms that can be applied to novel problems. I am currently a Machine Learning Scientist at Pendulum Systems. Before, I worked as a Machine Learning Researcher at Morgan Stanley.

I received a Ph.D. in Electrical and Systems Engineering from the University of Pennsylvania, and an M.A. in Statistics from the Wharton School. I had postdoctoral stints in the Electrical Engineering and Computer Sciences department at the University of California, Berkeley, and the Electrical and Computer Engineering department at Rice University. I have also been a research intern at Facebook Artificial Intelligence Research in Montréal, and a visiting scholar at TU Delft in the Netherlands.

The core of my published research is related to machine learning and signal processing for graph-structured data. I have devised novel graph neural network (GNNs) architectures, developed theoretical insights that help explain and understand their strengths and limitations, and pioneered their use across diverse applications including power grids, sensor networks, multi-agent robotics, and distributed control. My background in statistics, time series analysis, and signal processing has allowed me to bring a fresh perspective to machine learning problems, leveraging concepts from frequency analysis, filtering, ergodicity, and stochastic processes.

Our work on the stability of GNNs, a major contribution to the theory and understanding of GNNs, has received the 2022 IEEE Signal Processing Society Best Paper Award. Our work on multi-agent path planning has received the Cambridge Ring  Publication of the Year Award in 2021. My first journal article on GNNs (published at the end of 2018) has been one of the top 25 downloaded articles in 2020 for IEEE Transactions on Signal Processing. Our work on graph recurrent neural networks got the best student paper award in EUSIPCO 2019. I have been awarded the Joseph D'16 & Rosaline Wolf Award for the best dissertation by a male Ph.D. candidate in the ESE department at the University of Pennsylvania.

As of August 2022, I have published 21 journal articles in peer-reviewed journals (TPAMI, Proc. IEEE, SPM, TSP, among others), and I have presented my work at over 40 conferences (NeurIPS, ICLR, ICASSP, DSLW, CDC, to name a few). Google Scholar shows my work has more than 1200 citations, with an h-index of 18 and i10-index of 23.
