Experience

January 2012 to CurrentResearch Chemist / Staff Fellow
Rockford , IL

Plan and manage toxicological and pharmacokinetic bioassays, analyzing all formulation-related and biological samples and performing non-compartmental analysis on data.
Direct study activities, including formulation mixing and supply purchasing to maintain uninterrupted continuation of study while working collaboratively with study director, animal technicians, diet preparation, and other team members to achieve study objectives and advance organizational mission.
Uncover opportunities to improve workflow and maintain high quality standards by optimizing formulation mixing protocols, performing stability testing, testing gavage pump accuracy, certifying dose concentrations, and certifying test articles using LC-UV, LC-MS, LC-MS/MS, and NMR.
Develop sample preparation and LC-MS, LC-MS/MS, and HPLC-UV methods to conduct quantitative and qualitative analyses on compounds such as drugs, metabolites, DNA adducts, cosmetology products, and food products, supporting ongoing toxicological studies conducted at NCTR for the FDA.
Perform complex quantitative analyses using stable isotope dilution LC-ESI/MS methods and qualitative analyses using LC/MS, GC/MS, NMR, LC-UV, and other techniques.

January 2010 to Current

Conceptualized, coordinated, and oversaw studies examining nephrotoxicity following co-exposure to melamine and cyanuric acid in adult rats (sub-chronic study), in neonatal rats (treatment PND 1-21) and during recovery study after 90-day co-exposure to melamine and cyanuric acid.
Conducted PK study evaluating pharmacokinetics of oseltamivir and its pharmacologically active metabolite oseltamivir carboxylate in non-pregnant rhesus macaques and during three trimesters of their pregnancy.
Designed high-throughput LC-MS/MS method to analyze oseltamivir and oseltamivir carboxylate in rhesus macaque plasma, enabling analysis of 150 samples per day and 3,000 samples within one month.
Developed simple "one-pot" liquid-liquid extraction sample preparation and hydrophilic interaction liquid chromatography isotope dilution mass spectrometry method to quantify nicotine, cotinine, and two tobacco-specific nitrosamines (NNN and NNK) in small blood serum volume, allowing for high-throughput preparation of 100 samples per hour without automation; publication in peer review process.
Realized and performed experiments to elucidate oxidative mechanism underlying cleavage of diphenyl ether bond of triclosan during incubations with human liver microsomes (CYPs) in isotopically-enriched water, using LC-MS and LC-MS/MS to perform qualitative analyses; published findings in Archives of Toxicology.
Devised and validated ultra-sensitive LC-MS/MS method to quantify 4-hydroxy-1-(3-pyridyl)- 1-butanone (HPB) in HPB-releasing DNA adducts derived from tobacco-specific nitrosamines.
Experience National Center For Toxicological Research (NCTR) / Food and Drug Administration (FDA).

Oak Ridge Institute For Science And Education ORISEJanuary 2010 to January 2012Postdoctoral Fellow
MA

Performed stability testing, dose certifications, gavage pump accuracy testing, and test article analysis for two toxicological bioassays following good laboratory practice (GLP) regulations, including preparing standard operating procedures and conducting all chemistry analyses.
Co-designed, managed, and provided analytical support to two studies addressing nephrotoxicity from co-exposure to melamine and cyanuric acid in F344 rats -sub-chronic study in adult rats and in newborn rats from PND 1 to 21 (weaning).
Developed HPLC-UV method to quantify melamine and cyanuric acid in 0.1% and 0.5% carboxymethyl cellulose dosing formulations.
Optimized ball-milling process of melamine and cyanuric acid using laser-diffraction particle size analyzer.
Synthesized highly-selective derivatization reagent for alkyne-bearing compounds, and designed sample preparation procedures and LC-MS/MS methods.
Research Assistant at the University of Basilicata in Italy, Research Assistant at the University of Texas at Arlington, and Research and Teaching Assistant and Researcher at Charles University in Prague in the Czech Republic.
