Avrilia Floratou

Principal Scientist Manager


I am a Principal Scientist Manager at Microsoft’s Gray Systems Lab (GSL).

My research broadly lies in the area of data management with a recent focus on frameworks that simplify data science workflows. My research interests also include large-scale stream processing, relational databases, benchmarking and performance tuning of Big Data platforms. I’m currently working on simplifying various aspects of data science workflows such as data exploration, data preparation, and feature engineering among others. Previously I worked on the Dhalion project, a framework used to define and apply SLO-based policies on long-running applications that has been deployed in various Microsoft services.

Prior to my current role, I was a research scientist at IBM Almaden Research Center working on SQL-on-Hadoop engines and natural language interfaces for databases. I received my Ph.D. and M.Sc. in Computer Science from University of Wisconsin-Madison working with Prof. Jignesh M. Patel and my B.Sc. from University of Athens in Greece.
