      Research Interests<\/h3>\n
      \n\t

      Kinetic analysis of complex gas phase reactions related to environmental chemistry, pyrolysis and combustion. I have a background as experimentalist (laser photolysis \/ LIF detection; low pressure flame studies using MBMS techniques or flow reactors combined with GC analysis) but work recently mainly on ab initio calculated thermochemistry. The objective of my current research is to develop software that automatically generated concise but complete reaction networks for predetermined conditions using a rate-based criterion for reaction selection.<\/p>\n<\/div>\n<\/div><\/div>
