Joachim Rosenthal is Professor of Applied Mathematics in the Department of Mathematics at the University of Zürich. From 2011-2013 he served as Chair of the Mathematics Department and from 2016-2020 he has been Vice Dean of the College of Science. He received the Diploma in Mathematics from the University of Basel in 1986 and the Ph.D. in Mathematics from Arizona State University in 1990.
His current research interests are in coding theory and cryptography. In coding theory he is interested in convolutional codes, LDPC codes and more general codes on graphs. In cryptography his main interest lies in the area of postquantum cryptography, in particular in the area of code based cryptography. He serves currently on the editorial board of SIAM Journal on Applied Algebra and Geometry (SIAGA), Advances in Mathematics of Communications (AMC), Journal of Algebra and Its Applications (JAA), Journal of Algebra Combinatorics Discrete Structures and Applications, International Journal of Information and Coding Theory (IJOCT).
Since 2004 he has been one of the two moderators (with Madhu Sudan) of the Information theory section of arXiv. In August 2002 he served as the Symposium Chair of the International Symposium on Mathematical Theory of Networks and Systems (MTNS).
