Gwenola Burgot, Pharmacist, PhD, formerly Professor in Analytical Chemistry, Faculty of Pharmaceutical and Biological Sciences of University of Rennes 1. Scientific adviser for the collection database "Techniques de l'Ingénieur". Her research interests and publications involve the determination by continuous adiabatic titration calorimetric method of physicochemical equilibrium, water/n-octanol kinetic and thermodynamic parameters of transfer of drugs and the optimization of analytical methods for quantitative analysis of drugs in pure form or formulations.
