Joachim Weickert is professor of mathematics and computer science
at Saarland University where he heads the
Mathematical Image Analysis Group since 2001.
He received a diploma and a Ph.D. degree
in mathematics from the University of Kaiserslautern (1991, 1996), and a
habilitation degree in computer science from the University of Mannheim
(2001). He worked as research assistant at the
University of Kaiserslautern,
as post-doctoral researcher at the universities of
and as assistant professor at the
University of Mannheim.
Joachim Weickert performs
in image processing, computer vision and
scientific computing, focussing on techniques based on partial differential
equations, variational principles, wavelets, morphological and nonlocal
He has developed mathematical models and efficient numerical algorithms for
image restoration, enhancement, segmentation, compression, optic flow
computation, stereo reconstruction, shape from shading, as well as signal
processing methods for tensor fields. These ideas have entered a number of
applications in industry, biomedical image analysis and other fields.
The scientific work of Joachim Weickert covers 290 refereed
publications. They have led to over
citations and an
h-index of 62. Joachim Weickert is editor-in-chief of the
Journal of Mathematical Imaging and Vision.
He has been serving in the editorial boards
of nine international journals and has been
reviewer for more than 60 journals and 18 funding organisations.
He has given over 160 invited talks
at conferences, workshops and other universities, and was area chair of
six ECCV or ICCV conferences. Joachim Weickert has received 26
research, teaching and reviewing
awards, including a
Gottfried Wilhelm Leibniz Prize which is the
highest German research award.
He is elected member of the
Academia Europaea - The Academy of Europe.
At Saarland University, Joachim Weickert is initiator and head of
Programme in Visual Computing, which is the first of its kind in
Germany and uses English as language of instruction. He has supervised
more than 240
master theses. Joachim Weickert has established many interdisciplinary
collaborations with colleagues from medicine, bioinformatics, pharmacy,
physics, mechatronics, and mechanical engineering.
He is Principal Investigator for Visual Computing within the
Multimodal Computing and Interaction Cluster of Excellence, and he
serves in the Steering Committee of the
Intel Visual Computing Institute. From 2008 to 2010,
he was dean of the Faculty of
and Computer Science.
