Since Fall ’17, I am a full professor at Texas A&M University’s Computer Science & Engineering Department, and currently I am also an Associate Director for Texas A&M’s Global Cyber Research Institute. Previously, after receiving my PhD in Computer Science from Penn State, I did a postdoc at the Weizmann Institute of Science (Israel), and held research positions at the IBM T.J. Watson Research Center, Bell Labs, AT&T Labs–Research, and Yahoo Labs.

During Fall ’25 and Spring ’26 I am also a Visiting Professor in the Department of Computer Science of the University of Buenos Aires, Argentina.

My current research interests include both foundational and applied aspects of cryptography and information security. In more detail, they include:

• Cryptographic protocols and schemes
• Secure multiparty computation
• Blockchain protocols and cryptocurrencies
• Cryptography and game theory
• Distributed computing, consensus problems
• Algorithms

I have co-authored over 200 works (including articles, patents, and edited volumes) in the areas of cryptography, network security, distributed computing, and algorithms. Besides numerous contributions of a foundational nature to the area of cryptographic protocols and schemes (secure multi-party computation, verifiable secret sharing, oblivious transfer and commitment schemes, zero-knowledge, timed-release cryptography, “rational” cryptography, Byzantine agreement and consensus protocols, blockchain protocols), I have been involved in the design, analysis and implementation of a variety of secure systems, and I am the recipient of a Thomas A. Edison Patent Award, two Bell Labs Teamwork Awards, an IBM Outstanding Technical Achievement Award, and an IBM Research Division Award. In 2018 I became a Fellow of the International Association for Cryptologic Research (IACR).

I’m originally from Argentina, and my Erdos number is 2.
