I am an Assistant Professor at the Kahlert School of Computing at the University of Utah. Previously, I was a research scientist and a postdoctoral associate at the Computer Science and Artificial Intelligence Laboratory (CSAIL) of MIT where I worked with the A.M. Turing Award recipient Michael Stonebraker.
I earned my Ph.D. in Computer Science from Purdue University under the supervision of Walid Aref and Mourad Ouzzani.
My research interests revolve around data management in general and data quality in particular.
Data scientists spend most of their time doing "grunt" work, i.e., discovering, preparing and cleaning the data. The goal of my research is to build systems that target the main pain points in data science development: Data discovery; Data preparation and Data debugging.
In collaboration with industrial parties (e.g., Intel, Massachusetts General Hospital), my systems are motivated by real-world use cases.
