Currently employed as the CTO for Extracta, a small Brazilian biotechnology company, where successfully designed and implemented the first Brazilian high throughput screening program involving the preparation of the collection, assay development and validation, automated screening against in vitro biological activity assays and the identification, isolation and chemical characterization of the active compounds. Would like to return to North America or Europe to work with other researchers to develop creative solutions in drug discovery with focus on medicinal chemistry or coordinated discovery programs. 15 years experience in organic chemistry including doctorate research and biotechnology based companies.

Work & Research Experience:

Extracta Moléculas Naturais SA, Rio de Janeiro, Brazil

Director, CTO September 2001 -present

Technical Development Director, September 1999 - August 2001

Chemistry Manager, February 1999 - August 1999

R&D company started in 1999 committed to add value to the Brazilian Biodiversity through the discovery of new bioactive molecules for the Pharmaceutical, Veterinary, Cosmetic and Agro Industry. Led the implementation of the scientific plan of the company designing the program, recruiting and managing a team of 35 scientists and technicians. Actively participated in the development of protocols for collection and sample processing, assays development and automation, bioguided fractionation, hit isolation and structure elucidation.

Neurogen Corporation, Branford, CT USA
