Aditya Parameswaran

Starting July 1, 2019, I will be an assistant professor in the School of Information (I School) and Electrical Engineering and Computer Sciences (EECS) at the University of California, Berkeley.

I am presently an assistant professor of Computer Science at the University of Illinois (UIUC).

My research interests are broadly in building tools for simplifying data analytics, i.e., empowering individuals and teams to leverage and make sense of their datasets more easily, efficiently, and effectively.

Biographical Sketch

Aditya Parameswaran is a soon-to-be (starting July 1) Assistant Professor in the School of Information (I School) and Electrical Engineering and Computer Sciences (EECS) at the University of California, Berkeley. Aditya Parameswaran is currently an Assistant Professor in Computer Science at the University of Illinois, Urbana-Champaign. He spent a year as a PostDoc at MIT CSAIL following his PhD at Stanford University, before starting at Illinois in August 2014. He develops systems and algorithms for "human-in-the-loop" data analytics, synthesizing techniques from database systems, data mining, and human computation.

  • —, 2019: Berkeley logo *BIG NEWS!* I am moving to UC Berkeley, starting early Summer, with a faculty appointment at the School of Information and the EECS Department. Berkeley has been making some exciting moves in the broad data and information space, including a new Division of Data Science and Information, a very popular Masters in Information and Data Science program, and a new and increasingly popular data science major. I'm looking forward to being a part of this journey, and to moving back to the Bay Area! Illinois has been a wonderful home for the past 5-odd years with terrific students, a collegial research environment, and Midwestern charm (plus baby goats!); I'm going to miss my colleagues, the university, and the town terribly.

Synergistic Activities

I am an Associate Editor for SIGMOD Record, focusing on vision articles. Please consider sending us your most controversial and/or interesting papers!

I serve on the steering committees of HILDA (Human-in-the-loop Data Analytics) at SIGMOD and DSIA (Data Systems for Interactive Analysis) at VIS. Lots of excitement around this nascent area at the intersection of databases, data mining, and visualization/HCI - join us!

This cycle, I am serving as an Area/Associate Chair for HCOMP 2020, VLDB 2020, and SIGMOD 2020, as a Program Committee member for VLDB Demo 2019 and HILDA 2019 (phew!) I've served on the program committees of VLDB, KDD, SIGMOD, WSDM, WWW, SOCC, HCOMP, ICDE, and EDBT, many of them multiple times.

I co-organized HILDA 2017. I was the SIGMOD 2016 Undergraduate Research Chair.
