Divesh Aggarwal

Divesh Aggarwal is an Associate Professor in the Department of Computer Science at the National University of Singapore (NUS) and a Principal Investigator at the Centre for Quantum Technologies (CQT). He holds a PhD from ETH Zurich (2012) and was a postdoc at EPFL and New York University. His research focuses on discrete structures in theoretical computer science, with emphasis on cryptography, lattices, computational number theory, and coding theory. Aggarwal has advised numerous PhD students and postdocs, and his work bridges cryptography, quantum computing, and algorithm design. He is involved in editorial roles for journals like Information Processing Letters and serves on program committees for top conferences such as CRYPTO, EUROCRYPT, and STOC.

Education: PhD in Computer Science from ETH Zurich (2012), under Prof. Ueli Maurer. Postdoctoral research at EPFL (School of Computer and Communication Sciences) and NYU (Department of Computer Science).

Research Interests:

• Information-theoretic Cryptography
• Randomness Extractors
• Lattice Algorithms and Applications
