Objective:

A highly motivated synthetic chemist is seeking an opportunity to work in a successful pharmaceutical company. With my experience, from synthetic research to process development to GMP production, from medicinal chemistry to out-sourcing, will greatly benefit your organization.

Summary:

Process chemistry: Synthetic route design, scale up, technical transfer and GMP production; synthesis of active pharmaceutical ingredients, generic drugs and reference compounds; identification and synthesis of drug metabolites, process impurities; crystallization condition and polymorph screening; good communication skill and ability to work within cross-functional teams with aggressive timelines.

Medicinal chemistry: SAR and modeling study in small molecule drug discovery; making large scale intermediate in house on time; solid phase combinatorial chemistry in new drug discovery; outsourcing co-ordinate.

Natural product synthesis: Synthesis and modification of steroid compounds, synthesis of oligonucleotides, carbohydrates, peptides and heterocyclic compounds.

Broad knowledge and hands-on experience: Spectroscopic methodologies, such as NMR, MS, IR, UV, TGA, DSC and fluorescence; HPLC, GC. Experience with Reaction Colorimeter and Flow Reactor.

Working Experience:

Genzyme: (Waltham, MA. From Sept. 2004 – present)

Sr. Scientist – Process Chemistry: Process development and scale up; synthetic route design, optimization and technical transfer; synthesis of reference compounds, drug metabolites and process impurities; crystal salt formation and polymorph screening; medicinal chemistry and large scale intermediates synthesis; participating CMC meetings; mentoring junior chemists. I have completed three cGMP projects, from medicinal chemistry to kilograms (100 L reactor) GMP phase I material production.

Prime Organics: (Lowell, MA. From May, 1999 – August, 2004)

Sr. Scientist - Custom synthesis from mg to kg scale (100 L) in broad chemistry; synthesis and scale up of advanced intermediates; process development of generic drugs (Clopidogrel, Gleevec, Taxol); making oligonucleosides, peptides and phosphoramidites; synthesis and modification of cardiac steroids.

Sepracor: (Marlborough, MA. From July, 1998 – May, 1999)

Synthetic Chemist – Worked on several process developments of highly enantiomerically pure intermediates and drug candidates; synthesizing metabolites of anti-depressant drug, such as Desipramine, Metoclopramide, Zolpidem and Venlafaxine.

Biogen: (Cambridge, MA. From Dec. 1997 – June, 1998)

Medicinal Chemist - Synthesis 1, 3, 7 and 8-substituted xanthine derivatives as adenosine receptor antagonists and SAR studies; using solid phase combinatorial techniques synthesizing peptides in new drug discovery.

Education and Post-Doctoral Experience:

Southern Mississippi University, Post-doctoral Fellowship (from Dec. 1996 - Dec. 1997)

Study photo-degradation and photo-stability of polystyrene and acrylate / styrene co-polymer. Study radical polymerization and photo-initiator effect on polymerization. (Advisor: Professor C. E. Hoyle)

University of Bristol, UK. Post-doctoral Fellowship (from Oct. 1994 – Nov. 1996)

Synthesis and modeling study of bi-cyclic medium-ring compounds with N, P and B bridgeheads. Synthesis of C-13 labeled fatty acids and N-14 labeled amino acids. (Advisor: Professor R. W. Alder)

University of Wales, Swansea, UK Ph.D. and Master Degrees in Organic Synthesis

Ph.D. Advisors: A. Pelter and K. Smith; Master Degree Advisors: R. Khan and K. Smith.

Study novel organoborane reactions and their application in asymmetric synthesis (1990 – 1994).

Carbohydrate chemistry. Improvement and patented of synthesis of Sucralose (1989 -1990).
