I am a PhD candidate at Northeastern University and part of the DATA Lab. I am very fortunate to be advised by Prof. Reneé J. Miller.

My research interests lie in Data Integration, specifically in identifying, extracting, and classifying semantic properties of data values in the context of large heterogenous data lakes as well as web tables.

I am currently on the job market looking for full time positions!
