Raghavendra Addanki

I am a Research Scientist at Adobe Research (San Jose, California). I completed my Ph.D. in Computer Science from the College of Information and Computer Sciences at the University of Massachusetts Amherst in May 2022, where I was co-advised by Prof. Andrew McGregor and Prof. Cameron Musco. I received a Dissertation Writing Fellowship for my Ph.D. thesis. I was a visiting student in the Causality program at the Simons Institute for the Theory of Computing, Berkelely in 2022. Prior to this, I completed my Bachelors and Masters degrees (dual degree) in Computer Science from the Indian Institute of Technology Madras in 2016.

Research Interests

I am broadly interested in the design and analysis of algorithms for data science, causal inference, theoretical computer science, and machine learning. During my Ph.D., among other things, I have worked on identifying new connections between combinatorial optimization and causal inference.
