Brief Background

José is an analytical chemist with over 20 years of experience in drug discovery and development in pharmaceutical, biotech, and academic organizations. He has extensive experience in the development of bioanalytical methods for small molecules, and has focused in recent years on the design and application of in vitro drug metabolism assay methods using predominately liver S9 fractions, liver microsomes, and primary hepatocytes. José joined the EIDD in 2011 to lead the Drug Metabolism function of Bioanalytical Chemistry, Drug Metabolism, and Pharmacokinetics.

He began his industrial career in 1989 at Battelle Memorial Institute in Columbus, Ohio in the Product Registration and Evaluation Division, where he conducted drug metabolism studies using HPLC and other analytical methodologies. In 1999 he joined Solvay Pharmaceuticals, Inc. where he primarily conducted in vivo metabolite ID studies in samples from first-in-man Phase I clinical trials using LC/MS, LC/MS/MS and HPLC/UV. José also worked for AtheroGenics, Inc. where he developed and validated bioanalytical methods under the rigors of GLP principles. While there he performed the analysis of thousands of clinical study samples using state-of-the art sample preparation techniques and LC/MS/MS methods. José has authored or co-authored over 12 research papers and abstracts.
