Meet Our Team


Matthew S. Halquist, Ph.D.

Laboratory Director, Associate Professor


Matthew Halquist, Ph.D., is an associate professor in the Department of Pharmaceutics, School of Pharmacy. He received his bachelor’s degree in biology in 1998 along with minor studies in chemistry and forensics science. After eight years of working at PPD Bioanalytical Labs in Richmond, Virginia, developing and validated LC-MS bioanalytical methods under cGLP regulations, he returned to graduate school to obtain a Ph.D. in pharmaceutical sciences. During his graduate work, Halquist continued working as technical director in the Bioanalytical Shared Laboratory at VCU directing collaborations and helping graduate students with their research. Since 2015, Halquist has been the director of the Bioanalytical Shared Resource Laboratory and continues to foster collaborations within VCU and with other academic and industrial partners. His research interests include bioanalytical techniques for analysis of therapeutic proteins, tobacco product characterization and biomarkers of exposure, pharmacokinetic studies, separation sciences, stability indicating methods, and building in vitro release devices than can predict in vivo performance of parenteral dosage forms.

Leon Kosmider

Leon Kosmider, Pharm.D., Ph.D.

Affiliate Faculty


Leon Kosmider is an affiliate assistant professor of the Bioanalytical Shared Resource Laboratory within the Department of Pharmaceutics at the VCU School of Pharmacy. After Dr. Kosmider received his Pharm.D, he earned his PhD in Pharmacy and Toxicology from Medical University of Silesia, Poland. He has conducted research in toxicology of various tobacco products including e-cigarettes and cigarettes. He has studied smoking topography and yields of toxic agents in tobacco smoke and e-cigarette vapor generated under various smoking conditions. Dr. Kosmider was the Principal Investigator for the design and construct smoking machine - Palaczbot. Twice at Queen Mary University for two months internship. He was involved in the standard development for electronic cigarettes and e-liquids as an expert for the Polish National Committee for Standardization, the European Committee for Standardization, and the International Organization for Standardization.

Vinit V Gholap, Ph.D.

Recent Alumni now working for Merck in Boston, MA


Vinit was a graduate student in Department of Pharmaceutics at Virginia Commonwealth University (VCU).  Vinit received his Bachelor in Pharmacy from University of Pune, India in 2010. He later earned his MS in Pharmaceutical Sciences from University of Southern California. After achieving his MS, he joined pharmaceutical industry, Piramal Healthcare in Analytical Research and Development. As an analytical scientist, he worked on several dosage forms such as tablets, injections, liposomes and semi-solids. With industrial expertise developed in method development, validation and technology transfer, he decided to move back to academia to achieve his doctoral degree in Biopharmaceutical Analysis. He obtained his doctoral degree at VCU under the mentorship of Dr. Matthew Halquist. His research was focused on analysis of e-cigarettes. He has presented his research on e-cigarettes in SRNT conferences. He is also a recipient of Schwartz Award, Thakker Award and Graduate Poster Award at VCU. Besides being passionate about the analytical field, he enjoys being active member of professional committees such as AAPS and SRNT. He now resides in Boston and works for Merck in Boston, MA.

Catherine Del Guidice, Ph.D.

Recent Alumni now working for the FDA


Catherine Del Guidice received a B.S. in Chemistry from Christopher Newport University in 2011. She then received a M.S. in Clinical Laboratory Sciences with a concentration in Clinical Chemistry in 2014 from Virginia Commonwealth University, at which point she became a certified medical technologist (ASCP). While working on her Masters degree, Catherine worked at both the Division of Consolidated Laboratory Services as a Scientist I and at St. Mary’s Hospital as a Medical Laboratory Technician. Upon graduation, she accepted a full-time position at St. Mary’s Hospital as a Medical Technologist in the Chemistry and Hematology Laboratory. In 2015, she left St. Mary’s Hospital to work at PPD Laboratories as a Quality Assurance Auditor. Following that, she continued working at PPD Laboratories as a Project Manager for the Biologics by LC-MS/MS Research and Development group. While employed as a Project Manager, Catherine completed her Ph.D. part-time in Pharmaceutical Sciences under the mentorship of Dr. Halquist. Her research was focused on method development for quantification and characterization of antibodies and antibody fragments in human biofluids (plasma, vitreous and aqueous fluid) using hybrid LBA-LC-MS/MS. She is now working at the FDA.
