I am a postdoctoral scholar at the New York University, working with Prof. Yevgeniy Dodis in the Cryptography Lab. Before joining NYU, I completed my PhD in the Cryptography and Information Security Research Group at ETH Zürich, Switzerland, under the supervision of Prof. Ueli Maurer. I hold a bachelor's and master's degree in computer science from ETH Zürich.

I am interested in a broad spectrum of the field of cryptography, ranging from the foundational theoretical aspects of cryptography to the design and analysis of practical protocols. In particular, my research interests encompass the following topics:
