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).
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.
Currently, he is a teaching assistant at Grenoble
INP, member of the Statify team of
Laboratoire Jean
Kuntzmann. He is the head of the statistics and data science tracks of the international Master's programme MSIAM (Looking for a high-level postgraduate programme in Data Science or Statistics? Have a look and apply at http://msiam.imag.fr/).
He teaches at the "École Nationale Supérieure d'Informatique
et de Mathématiques Appliquées de Grenoble" Ensimag
(engineering school of applied mathematics and
computer science). Topics: fundamentals of statistics,
computational statistics.
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.
Plants are branching living organisms that develop throughout
their lifetimes. Organs are created by small embryogenetic
regions at the tip of each axis, called apical meristems.
In the above projects, we are interested in studying
plant apical meristem functioning and development. We believe
that a detailed analysis of apical meristem processes, based
on advanced mathematical and computational methods and tools,
will lead us to get a deeper and better understanding of plant
development.
