PROFESSIONAL EXPERIENCE
JOHNSON & JOHNSON PHARMACEUTICAL RESEARCH & DEVELOPMENT, San Diego, CA • 2010-Present
Research Associate (On Assignment through Kelly Services/US Tech Solutions, no end date postion)
Selected to support drug discovery initiatives as contract employee of global pharmaceutical preparations manufacturer. Under restrictive deadlines, develop bioanalytical methods (API 4000 LC/MS/MS methods) for approximately 5 compounds per week for DMPK in drug discovery. Perform protein crash and prepare calibration standards/quality controls; establish highly accurate/consistent results for plasma, lung, and brain samples in 96 well plates (automated and non-automated). Utilized rapid equilibrium dialysis device and LC/MS/MS (API 4000, ESI) to screen batched compounds for plasma protein binding.
• Acquired comprehensive knowledge of DMPK assays and gained proficiency troubleshooting matrix effects and ion suppression issues.
• Validated data to assure quality, completeness, and reliability of information and presented results to research scientists and associates in immunology/neuroscience/cardiovascular.

Analyst I
Performed broad range of laboratory processes and analytical tests in analytical group with private drug development/manufacturing company, specializing in creating new formulations of existing drugs using novel polymeric technologies. Conducted quantitative analyses within non-GLP, preclinical environment; supported formulation studies, in vivo/vitro studies, and stability tests. Utilized HPLC, ELISA, Karl-Fischer, and dissolution tester to complete quantitative analyses and characterization of proteins, peptides, and small molecules in polymer for formulation.
• Played key role in maintaining and troubleshooting variety of equipment and instrumentation, specifically HPLCs, ensuring optimal functioning and guaranteeing reliability and accuracy of data collected.
EDUCATION
Master of Science in Chemistry, emphasis in Analytical Chemistry, San Diego State University – San Diego, CA • 2010
• Thesis: “Method Development for Analysis of Testosterone / Epitestosterone in Human Samples Using LC/MS/MS,” Supervisor: Prof. Dale Chatfield
• Research Focus: Separated testosterone/epitestosterone using C8 column with LC/MS/MS (Thermo TSQ Quantum, ESI/APCI). Developed method for urine sample preparation, enzymatic hydrolysis of steroid conjugates followed by solid supported liquid-liquid extraction. Obtained 10 pg/mL LOD and 50 pg/mL LOQ from standard solutions and reconstituted urine samples with faster, more sensitive method than existing GC/MS/MS methods.
Bachelor of Science in Chemistry, University of Utah – Salt Lake City, UT • 2002
