Dr Jean Michel Létang

Jean Michel Létang graduated in 1990 from INSA Lyon (electrical engineering dpt) in France. He received his PhD degree in Signal and Image processing from INP Grenoble in 1993. He held several post-doctorate positions in computer vision at INRS-telecom in Montréal (Canada) and at INRIA Grenoble. In 1996 he joined the medical imaging department of Philips Research Laboratories in Paris as a research engineer. Since 1999, he has been an associate professor in nondestructive testing at INSA (mechanical engineering dpt) and conducted his research at the CREATIS medical imaging laboratory. His main research interest in on Monte Carlo simulations for particle transport, and in particular the development of fixed-force detection and variance reduction techniques based the track-length estimator for both imaging and dosimetry. He has been collaborating since 2005 with nuclear physics and instrumentation laboratories for prompt-gamma control in particle therapy. He is also closely involved in reconstruction techniques for tomography, both photons and protons, and in the development of wave modeling for x-ray phase contrast simulations. He has co-supervised more than 20 PhD thesis and co-authored more than 100 papers in international peer-reviewed scientific journals.
