PROFESSIONAL EXPERIENCE

09/2001 - 12/2011

Development Scientist III, Process Analytics, Biopharmaceutical Development Program (BDP)

SAIC-Frederick, Inc., Frederick, MD.

Pre-Clinical Development of Biologics:

• Developed and executed bioanalytical methods to determine therapeutic quality (identity, purity, stability, and potency) of biologics during late stage product optimization efforts.

• Ensured the on time delivery of critical material for clinical trials (non-pivotal phase III

for neuroblastoma) in multiple medical centers in United States and Canada by the timely development, completion, and oversight of multiple assays for multiple lots of a monoclonal antibody.

• Developed and delivered two peptide vaccines (2gram each) in final formulation buffer with and without CpG adjuvant for Phase I dose escalation studies (Vaccine Therapy in Preventing Cytomegalovirus in Healthy Participants. http://clinicaltrials.gov/ct2/show/NCT00722839).

• Evaluated interim process samples, drug substances, and product produced by third-party to determine product comparability and best assay methods in critical path of project transfer to third-party.

• Developed a BIAcore based binding assay to confirm the identity and specificity of an immunotoxin under evaluation for the treatment of a specific type of brain tumor.

• Collaborated and reviewed a PK study that determined the cardiovascular effect of salt, pH, counter-ions (TFA or acetate), and excipients in the formulation buffer of a potential drug.

• Conducted analyses and validation of medical devices (Gene-gun containing gold chelated DNA vaccine against Human Pappiloma Virus) to determine their safety, efficacy, and stability.

• Developed and evaluated the accuracy, precision, or reliability of new protocols for product development using parameters like system suitability controls, assay controls, limit of detection (LOD), limit of quantitation (LOQ) and standard curves.

• Worked with internal teams and Quality Assurance (QA) to successfully achieve GMP compliance as well as safety of medical devices and products.

01/1998 - 09/2001

Staff Fellow, Section of Histopharmacology, NIMH, NIH.

• Performed highly independent research in the area of molecular biology and protein chemistry.

• Identified, cloned, and characterized a point mutation in a calcium binding protein, calretinin, present in mesothelioma cells. Performed in vitro phosphorylation studies as well as molecular modeling studies were performed to characterize the WT and mutant proteins.

• Differential display along with RT-PCR, DNA sequencing, cloning, and Bioinformatics was used to identify an alternatively spliced variant of a caveolae associated protein, Flotillin-1, from frozen Parkinson’s disease brain sample. Brain localization of this particular protein was accomplished thorough in situ hybridization histochemistry.

• Developed a 2-D gel electrophoresis protocol for characterizing proteins present in various brain samples and is currently in use at Center for Molecular Medicine at Uniformed Services University, Bethesda, MD.

• Developed a database to combine the molecular and clinical patient data.

• Trained and mentored students and technicians.

02/1994 - 12/1997

Post-doctoral Fellow, Section of Molecular Biology, NIAAA, NIH.

• Purification and characterization of enzymes (pyruvate dehydrogenase complex).

• Cloning, expression, purification, and characterization of recombinant enzymes from bacteria and baculovirus expression systems; mutagenesis using PCR.

• Homology molecular modeling of enzymes (e.g. transketolase) and G-protein coupled receptors (e.g. serotonin receptor 1A1); founding member of the NIH Molecular Modeling Interest group.
