I am an Assistant Professor in the Computer Science department at Brown University. Currently, my research focuses on Big Data management systems for interactive data exploration and modern hardware. Before joining Brown, I spent 2 years as a PostDoc in the AMP Lab at UC Berkeley after receiving my PhD from ETH Zurich. At ETH, I was part of the Systems Group, where I worked on transaction management and stream processing in the cloud. I co-authored one of the first works taking a data management perspective on cloud computing and the first research paper on hybrid human/machine database systems. I was awarded an NSF Career Award (2015), an AFOSR Young Investigator award (2015), a Swiss National Science Foundation Prospective Researcher Fellowship (2010), a DAAD Scholarship (2006), a University of Sydney Master of Information Technology Scholarship for outstanding achievement (2005), the University of Sydney Siemens Prize (2005), two VLDB best demo awards (2015 and 2011) and an ICDE best paper award (2013).

Current Research Interests

  • Systems for Interactive Data Exploration
