I am a Ph.D. student in the Enterprise Platform and Integration Concepts Group at HPI, advised by Professor Hasso Plattner. The goal of my research is to make database systems cheaper and faster through the unique capabilities of cloud environments. I am particularly interested in all aspects around query processing on serverless cloud infrastructure. Before joining HPI, I built database systems at SAP, TU Berlin, UC Irvine, and IBM.

Research Area: Elastic Query Processing on Serverless Cloud Infrastructure
