Jeffrey Hoffstein, Ph.D., co-VP, Research and Founder
Jeff is a co-inventor of the NTRU public key cryptographic system, and a Professor of Mathematics at Brown University. Dr. Hoffstein has published more than 40 papers on the subjects of number theory and cryptography, and is the recipient of numerous National Science Foundation grants. Jeff has held academic positions at the University of Rochester, IAS and Göttingen University in Germany. He holds a B.A. from Cornell University and a Ph.D. from MIT.

Nick Howgrave-Graham, Ph.D.
Nick is a Senior Cryptographer at NTRU. He has published many papers on cryptography and number theory, including joint work showing that moduli of the form N = p^rq can be easily factored for large r, and an interesting attack on the digital signature algorithm (DSA), demonstrating that many practical implementations of this algorithm are insecure. He is co-inventor and patent holder of the NTRU signature algorithm. In addition to his research and peer-reviewing, he contributes to the cryptographic community both by invited lectures (IPAM Contemporary Methods in Cryptography, AMS Short Course on Cryptography) and in program committees (CT-RSA 2006, PKC 2006). Nick co-developed the NTRU process for threat model analyses, and is heavily involved with the security consultancy that NTRU provides. Before coming to NTRU, he worked for two years at the IBM, Yorktown Heights Research Lab in New York. He holds a B.A. from the University of Wales, Aberystwyth, and both an M.Sc. and Ph.D. from the University of Bath, UK

Jill Pipher, Ph.D., Director of Research and Founder
Jill is a co-inventor of the NTRU public key cryptographic system, and a Professor of Mathematics at Brown University. She received the Sloan Foundation Fellowship in 1989, the Presidential Young Investigator Award in 1990 and has received numerous grants from the National Science Foundation. In addition to cryptography, her research interests include harmonic analysis, probability and partial differential equations. She has published over 20 articles on analysis and cryptography, and taught at the University of Chicago before coming to Brown University. Jill holds a B.A. and Ph.D. from UCLA.

Joseph Silverman, Ph.D., co-VP, Research and Founder
Joe is a co-inventor of the NTRU public key cryptographic system. A Professor of Mathematics at Brown University for more than 10 years, Joe has previously held academic positions at MIT, Boston University and Universite de Paris VII. He authored four standard reference texts on Elliptic Curves and Number Theory, and published over 70 articles on number theory, geometry and cryptography. Joe received the Guggenheim Foundation Fellowship 1998-1999, the American Mathematical Society Steele Prize in 1998, the Sloan Foundation Fellowship 1987 to 1991, and has also received a number of grants from the National Science Foundation. He holds a B.S. from Brown University and a Ph.D. from Harvard University.

William Whyte, Ph.D., Director of Cryptographic Research
(Products & Services)
William is Director of Cryptographic R & D for the company. Before joining NTRU, he was Senior Cryptographer with Baltimore Technologies in Dublin, Ireland. In NTRU his responsibilities include oversight of all aspects of product management and technology development. He has extensive speaking experience, having presented at industry and academic conferences and developed and delivered training courses on multiple subjects. He holds multiple patents, has published papers in the fields of cryptography and statistical mechanics, and contributed a lecture to the American Mathematical Society's intensive Cryptography Tutorial in Baltimore, Maryland in 2003. He holds a B. A. from Trinity College, Dublin, and a D.Phil. from Oxford University.
