Research Interests

My research centers around:

  1. Understanding the impact of internet technologies on users by empirically studying their interactions with such systems.
  2. Machine Learning, Natural Language Processing, Network Science, and Causal Inference for 1.

Professional Background

Starting Fall 2019, I am an Assistant Professor in the School of Information (SI) at the University of Michigan, where I research and teach various topics in Artificial Intelligence (AI), broadly defined.

I got my A.M. in Statistics and M.S.E. & Ph.D. in Computer Science from the University of Pennsylvania where I was advised by Profs. Lyle Ungar, Dean Foster (now at Amazon), and James Gee. During my time at Penn, I also worked closely with Dr. Brian Avants on topics related to Machine Learning in Brain Imaging. My Ph.D. thesis was entitled, "Advances in Spectral Learning with Applications to Text Analysis and Brain Imaging," and won the Best Computer Science Dissertation Award at Penn (Morris and Dorothy Rubinoff Award). It proposed novel statistical methods for problems in Text Modeling/NLP and Brain Imaging. More specifically, my doctoral dissertation proposed statistically and computationally efficient methods for the problem of learning word embeddings in NLP and for the problem of data-driven parcellation/segmentation of human brain images. Our methods not only gave predictive accuracies that were better or comparable to the state-of-the-art statistical methods (circa 2015) but also had strong theoretical guarantees. Please look at our JMLR 2015 and NeuroImage 2014 papers for more details. I also did other research in my Ph.D. on establishing connections between PCA and ridge regression (cf. JMLR 2013) and on provably faster row and column subsampling algorithms for least squares regression (cf. NeurIPS 2013a,b).

Towards the end of my Ph.D., I got interested in computational social science and causal inference. After finishing my Ph.D., I proceeded to complete a Postdoc with Prof. Sinan Aral at MIT. At MIT, I worked on several social science problems, e.g., finding influential individuals in a social network with realistic real-world assumptions (cf. Nature Human Behaviour 2018), devising revenue maximizing price discrimination strategies for newspapers (cf. Management Science 2020), and designing sequential interventions for news websites to help them maintain sustained user engagement. At MIT, I was also involved with the Initiative on the Digital Economy (IDE) on studying the economic and societal impacts of AI. I am still affiliated with IDE as a Digital Fellow.

Much before all this, I was a carefree undergrad studying Electronics & Electrical Communication Engineering at PEC in my hometown of Chandigarh, India. I developed my interest in AI/ML and the desire to pursue a Ph.D. as a result of three memorable summer internships, before my Ph.D., at Computer Vision Center @ Barcelona [summer 2006], Max Planck Institute for Intelligent Systems @ Tuebingen [summer 2008], and Information Sciences Institute/USC @ Los Angeles [summer 2009].

I always have openings for strong students in my group at all levels (Postdoctoral, Ph.D, Masters, or Undergrad). I am broadly looking to supervise students who are interested in working on ML, Computational Social Science, NLP, or Information Systems. Prior research experience in these areas is highly valued, as are strong programming skills and a solid applied math/statistics background.
