Scientific expertise and academic outputs

Dr. Eric TRABLY, 43 years old, is research engineer and deputy director at INRA-LBE. His academic background is about microbial ecosystem engineering and microbial metabolisms in mixed cultures. He defended his PhD in 2002 on the bioremediation of organic micropollutants and was then granted of a two-year EU Marie-Curie project about the characterization of the microbial processes involved in anaerobic xenobiotic biodegradation (Denmark). He joined then the National Institute for Agronomy in a research group interested in microbial removal of pesticides in soils.

Since 2007, Eric Trably has joined the INRA-LBE, and has been leading a research group on “Biohydrogen production by dark fermentation in mixed cultures”. He coordinated a French national project InGEcoH (“microbial ecosystem engineering”) with an objective of biohydrogen production. He has been involved in several national projects and three EU projects dealing with “biohydrogen – bioenergy - production from organic materials in fermentative bioprocesses”. Since 2010, Dr. Eric Trably has also been involved in several national major research programs in the domain of BioElectroChemical Systems, and is currently developing the concept of Electro-fermentation.


Overall, Dr. Eric Trably has supervised 13 PhD students, 9 Post-docs (> 1 year) and 38 MSc. He was awarded by the French ADEME price of Innovation in 2012 and 2013 about bioH2 production in fermentative systems. He has (co-)authored >270 references, including 4 patents, 70 papers in peer-review journals (80% in Q1), 15 major national chapters of book, and >100 communications in international conferences (9 as invited speaker - 3 keynote lectures). Since 2014, he has been involved as French representative at the International Energy Agency (IEA) - Hydrogen Implementing Agreement (HIA) in taskgroup 34 “BioH2”, and he is member of the Latino-American BioH2 Network. He has a H-index of 22 (Web of Science) or 27 (Google Scholars).
