Purva Pruthi
Ph.D. candidate at University of Massachusetts, Amherst
I am a fifth year MS/Ph.D. student at UMass Amherst, advised by David Jensen. My work lies at the intersection of causal inference, computational systems and machine learning. Specifically, I work on developing methods to learn causal models of the computational systems such as databases, software programs to enable automated causal reasoning in the complex real-world systems.
Many real-world systems have modular structure and can be represented as sets of interacting components. Examples of such systems include computational systems such as query processors, natural systems such as cells, and social systems such as families. Leveraging the modular structure of the world allows us to build data-driven models of the world that are re-usable, data efficient, and easily maintainable. Complex causal mechanisms governing these systems can also be decomposed into simpler causal mechanisms. My work focuses on understanding the benefits of explicitly modeling the compositional structure of the causal mechanisms in models and understanding the systematic generalization characteristics of compositional causal models.
I’ve also spent eight months (Sept 2021 - May 2022) as AI resident at Google X, The Moonshot Factory where I worked on applying causal inference techniques in solving the most challenging real-world problems. I also spent Summer 2018 at Amazon Cambridge, United Kingdom, working with Javier Gonzalez and Xiaoyu Lu on designing a transfer-learning framework for reinforcement learning focusing on environments with visually changing features but same underlying causal dynamics. Previously, I also worked with Madalina Fiterau at the intersection of causal reasoning and healthcare.
Prior to joining UMass as a graduate student, I worked at Goldman Sachs for three years. I worked on building statistical models for systematic investment strategies. I also worked on building statistical tools to analyze the root causes of undesirable behavior in trade settlement procedures.
I graduated from Indian Institute of Technology, Roorkee in 2015. During my undergraduate program, I worked with Durga Toshniwal on spatio-temporal diffusion analysis of online information on Twitter. I also enjoyed doing competitive programming as part of Programming and Algorithms group in college.
Outside work, I enjoy reading books, writing my thoughts about science and everything else (prose-style poetry). I love cooking, playing piano and taking long walks looking at the sunset, stars, (and sometimes the moon!)
