Short biography / Research topics

Jean-Baptiste Durand received the engineering degree in applied mathematics and computer science from the « Institut National Polytechnique de Grenoble » Grenoble INP (Grenoble Institute of Technology) in 1999. He received the Ph.D. degree in applied mathematics in 2003 from the University of Grenoble I (France), now Université Grenoble Alpes.

From 1999 to 2003, he worked on statistical modelling at the French National Institute for Research in Computer Science and Control (Inria), as a member of the IS2 project (Statistical Inference for Health and Industry). Then, he was a Postdoctoral Research Fellow at AMAP « Plant Modelling » mixed research unit, Montpellier (France), with a grant from CIRAD.

From 2004 to 2022, he was a teaching assistant at Grenoble INP, member of the Statify team of Laboratoire Jean Kuntzmann. He was the head of the statistics and data science tracks of the international Master’s programme MSIAM http://msiam.imag.fr/.
He taught the fundamentals of statistics and computational statistics at the « École Nationale Supérieure d’Informatique et de Mathématiques Appliquées de Grenoble » Ensimag (engineering school of applied mathematics and computer science). 
He was delegated to Inria team Virtual Plants (Inria Sophia) between September 2009 and August 2011 and to Inria team Statify between September 2019 and August 2021 .

His research interests include computational methods for hidden Markov models, statistical analysis of tree-structured processes, discrete multivariate distributions and applications to signal processing and botany.

He has returned to AMAP as a CIRAD researcher since 2022 and now aims at developing statistical models and approaches for the analysis of structured data issued from plant phenotyping.
