Mathias Lecuyer
I am a French New Yorker, and CS student at Columbia. Among many other things, I like to build stuff, learn new programming languages, travel, and rock climb. I also love to read, on topics ranging from econ to history and biology. My research is in distributed systems, I currently focus on leveraging statistics and machine learning to improve data management and transparency. I am also interested in the impact of the sharing economy.


Data has become the principal asset of the Internet era. While this data offers unique opportunities to improve personal and business effectiveness, it also poses serious risks to users' privacy, and to organizations, by exposing extensive data stores to external and internal attacks. In my research, I build tools and design mechanisms that leverage statistics and machine learning to: increase the current Web's transparency by revealing how personal data is being used; and enable a more rigorous and selective approach to big data collection, access, and protection, to reap its benefits without imposing undue risks.
