Les formateurs experts

Tom Fearn, from UCL – London’s Global University,UK

Tom Fearn is Professor of Applied Statistics in the Department of Statistical Science at UCL in London. His main research area is chemometrics, and in particular its applications to quantitative calibration and classification problems in NIR spectroscopy. He received the Tomas Hirschfeld award for contributions to NIRS in 2001 and is Immediate Past President of the International Council for Near Infrared Spectroscopy.

Federico Marini, from La Sapienza Università di Roma, Italy

Prof. Marini completed his PhD in 2004. In 2006, he was awarded the Young Researcher Prize from Italian Chemical Society and in 2012 he won the Chemometrics and Intelligent Laboratory Systems Award “for his achievements in chemometrics”. His research activity is focused on all aspects of chemometrics, ranging from the application of existing methods to real world problems in different fields to the design and development of novel algorithms. He is the past-coordinator of the Chemometric group of the Italian Chemical Society, and currently the vice-president of Italian NIR society and the coordinator of the Chemometric study group of EUCheMS.

Marina Cocchi from University of Modena and Reggio Emilia, Italy

Marina Cocchi is at present Associate Professor of Analytical Chemistry at University of Modena and Reggio Emilia. She got the PhD degree in Chemical Sciences in 1992 at the same University. Author of more than 100 publications on International Journals and books (H-ind 27, 2246 cit., Scopus). Main research topics: Multivariate, Multi-way and Multiset methods; Data Fusion; Feature selection; MSPC; Food Authenticity; Chemical fingerprinting by spectroscopy (MIR, NIR, NMR) and chromatography; Multivariate calibration; Experimental Design. She is member of editorial Board Chemometrics and Intelligent Laboratory Systems, and of Advisory Board of Comprehensive Chemometrics, Wiley, 2nd Ed.

Jean Michel Roger from INRAE, France

Jean-Michel Roger focused is research on the robustness problem. In 2003, simultaneously with Prof. Tom Fearn, he proposed a new generic method called External Parameter Orthogonalization (EPO) which permits to eliminate specific spectral effects from the NIRS calibration and thus to solve certain problems of robustness. He is also involved in the design of portable or online spectrometers using filters technology. In this aim, he developed a method (CovSel) that allows to select wavelengths with regard to multiple responses. He has created ChemHouse, a chemometrics research group, forge of the ChemFlow software (see https://chemproject.org).

Matthieu Lesnoff from CIRAD, France

Matthieu Lesnoff is biometrician at the Selmet (Mediterranean and tropical livestock farming systems) research unit in CIRAD. In chemometrics, he specializes in non-linear prediction methods, in particular on locally weighted PLSR approaches. He is actually in charge of developing a web platform for automated predictions of the composition of tropical forage compositions in CIRAD. He is member of the ChemHouse research group in Montpellier (https://chemproject.org) and has developed several chemometrics free packages in R and Julia languages (rchemo and Jchemo: https://github.com/mlesnoff ).
