Research Interests:

Broadly speaking, I am interested in Mathematics, Theoretical Computer Science and Cryptography. In particular, I am interested in the following:

The Geometry of Numbers,

Lattice Algorithms and Their Applications in Cryptanalysis,

Post-Quantum Cryptography (Lattice-based Cryptography),

Complexity Theory of Hard Lattice Problems,

Quantum Computation on Hard Lattice problem.

Academic Skills:

Overleaf, Dropbox, C++ (with NTL), SAGEMATH (with fp(y)LLL), Github, and Excellent academic writing.
