Status
I am a postdoc at the Computer Science Department of Yale University, hosted by Mariana Raykova.
Previously, I was a postdoc at Columbia University, hosted by Allison Bishop. In Summer 2015, I participated to the Cryptography program at the Simons Institute for the Theory of Computing. Before my appointment at Columbia, I was a postdoc at CUNY, hosted by Rosario Gennaro.
I completed my PhD in Computer Science at Aarhus University, under the supervision of Ivan Damgård (Aarhus University, Denmark) and Ronald Cramer (Leiden University / CWI Amsterdam, The Netherlands). From September 2012 until April 2013, I was a visiting student at the Courant Institute (New York University) to work with Yevgeniy Dodis and Oded Regev.
Research Interests
My main research area is cryptography, with a focus on: verifiable cloud computation, secure multiparty computation, secret sharing schemes. Broader interests in computer science and mathematics include applied probability, statistical estimation, algebraic geometry, numerical analysis, distributed algorithms.
