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 Utrecht and Copenhagen, and as assistant professor at the University of Mannheim.

Joachim Weickert performs research in image processing, computer vision and scientific computing, focussing on techniques based on partial differential equations, variational principles, wavelets, morphological and nonlocal methods. 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 more than 310 refereed publications. They have led to over 25000 citations and an h-index of 70. Joachim Weickert is editor-in-chief of the Journal of Mathematical Imaging and Vision. He has been serving in the editorial boards of ten international journals and book series, and he has been reviewer for more than 70 journals and 20 funding organisations. He has given over 190 invited talks at conferences, workshops and other universities, and was area chair of six ECCV or ICCV conferences. Joachim Weickert has received 32 research, teaching and reviewing awards, including a Gottfried Wilhelm Leibniz Prize which belongs to the highest German research awards. In 2017 he has been awarded an ERC Advanced Grant. He is elected member of the Academia Europaea - The Academy of Europe.

At Saarland University, Joachim Weickert is initiator and head of a Master 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 250 bachelor or 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 Mathematics and Computer Science.
