I obtained a B.Sc. in biochemistry in 1993 and a M.Sc. in chemistry (with honors) in 1996 from the Université du Québec à Montréal (Montréal, Québec, Canada). Later on, I earned a Ph.D. in natural resources sciences (soil science) in 2007 from McGill University (Montréal, Québec, Canada. During my Ph.D. studies, I developed a passion for the soil, because of its high importance for human life on earth, its essential functions, and the diversity of the forms of life that inhabit it and their complex interrelations.


At the same time, I also developed a passion for studying organic molecules and especially lipids. In my Ph.D. research, I was using an approach based on fatty acid profiling to characterize soil microbial communities. To acquire more knowledge about lipids and methods to study them, I became interested in working at the Kansas Lipidomics Research Center. As a biochemist, elucidating the diversity of molecules found in a highly complex environment like soil is a life-long challenge.  It will require hard work, intelligence, and collaboration with enthusiastic biochemists, chemists, biologists, and soil scientists who are fascinated by the rich biological and molecular diversity found in nature.


My current research goals are (1) to study plant and soil biota responses to anthropogenic and environmental factors using a lipidomics approach; (2) to contribute to the characterization of the biochemical complexity and cycling of organic molecules in soil ecosystems; (3) to develop mass spectrometry methods to study soil ecology, organic geochemistry, archeology and plant biology; (4) to improve the sustainable management of natural resources and biodiversity using OMICs approaches; and (5) to study relationships between human health and ecosystem health.





Currently, through the REU program in grassland ecology at Kansas State University, Dr Welti, Dr Blair and I, as co-mentors, are proposing three research projects to undergraduate students for summer 2008.  More details on these three projects could be found by going at the address of the program:


Briefly, these projects are:

1. Environmental Factors Controlling the Dynamics of Archaea Communities in Grassland Ecosystem  

2. Soil Algae in the Konza Prairie Grassland Ecosystem

3. Molecular Characterization of Grassland Soil Ecosystem by Mass Spectrometry

If you aren’t able to be part of the KSU REU program, I would like to invite you to communicate with me and express your interest in working on a related project.
