Justin Pritchard is a Senior Director in Analytical Development at Vertex Pharmaceuticals Incorporated working on the Analytical Development Leadership Team and leading two groups in the department, the Process Analytics & Control Team and the Dissolution Team. Vertex has the first automated continuous drug product manufacturing process with three approved products manufactured continuously. Justin and the PAC team are responsible for the development, implementation, and validation of PAT methods and for the implementation of an automated control strategy for continuous drug product manufacturing at Vertex. The dissolution team is also responsible for dissolution method development and justification for all clinical products and initial submissions. Justin has spent his career innovating in Analytical Development, the last 14 years at Vertex and, prior to that, working at Alkermes and Aphios. Justin also currently serves on the IFPAC Scientific Board.
Elizabeth Bielski, M.S., Ph.D. is a Senior Pharmacologist working at Division of Therapeutic Performance-I (DTP-I), Office of Research and Standards (ORS), Office of Generic Drugs (OGD), Center of Drug Evaluation and Research (CDER) at the FDA since October 2022. Prior to her role as a Senior Pharmacologist, she served as a Pharmacologist (October 2020-October 2022) and as a Chemist (January 2020 t-October 2020) within DTP-I. Her areas of expertise involve orally inhaled and nasal drug products (OINDPs) and drug-device combination products (DDCPs). She is actively involved in developing general and product-specific guidances, addressing controlled correspondences, pre-ANDA meeting requests, citizen petitions, internal consults, and collaborating on current research projects to promote generic drug development of OINDPs and DDCPs. Prior to joining the FDA, she served as an ORISE Fellow at FDA within DTP from August 2018-December 2019. Elizabeth completed her Ph.D. in Chemical Engineering from Wayne State University (Detroit, MI, USA) in July 2018 encompassing work also conducted at Department of Chemistry at the University of São Paulo (São Paulo, Brazil) and Department of Pharmaceutics at Virginia Commonwealth University (Richmond, VA, USA) related to novel inhaled drug delivery strategies for treatment of lung cancer and lung metastases. Prior to receiving her doctorate, she received her Bachelor of Science in Biomedical Physics Honors with University Honors in 2011, and her Master of Science in Biomedical Engineering in 2012 from Wayne State University.
James Mullin is a Senior Principal Scientist at Simulations Plus, Inc. and has a graduate degree in Chemical Engineering. In his role at Simulations Plus, he contributes to modeling and simulation development and consulting activities across multiple programs including GastroPlus, MembranePlus, and DDDPlus. Most recently, James is participating in an FDA grant project to extend the capability of Gastroplus to predict local tissue concentrations by enhancing the model structure. Additionally, he has developed models to predict partitioning in pulmonary tissues and simulate inhalation of vapors for purposes of toxicological modeling and assessments. James has 19 years’ experience in PBPK modeling, computational fluid dynamics, and mathematical modeling.
Dr. Ross Walenga joined the FDA in 2015 as an Oak Ridge Institute for Science and Education (ORISE) Fellow. He is currently a Chemical Engineer at the Division of Quantitative Methods and Modeling at the Office of Research and Standards. He began his career at Virginia Polytechnic Institute and State University (Virginia Tech), where he earned a Bachelor Science in Aerospace Engineering. He later earned his Ph.D. in Engineering (mechanical track) from Virginia Commonwealth University in 2014, where he also spent seven months as a postdoctoral fellow prior to joining the FDA. His research interests include computational fluid dynamics modeling of orally inhaled, nasal, ophthalmic, and dermal drug products to answer questions pertaining to bioequivalence.
Dr. Vaka is a Director of Formulation R & D, specialty product division at Amneal Pharmaceuticals. He obtained his Ph.D in Pharmaceutics & Drug Delivery from the University of Mississippi. After graduating, he worked at Kashiv Pharmaceuticals LLC., for about 8 years in R & D, focusing on 505(b)(2) programs. He developed GRANDE® (advanced gastric retention system) and KRONOTEC® (advanced osmotic oral drug delivery system) proprietary technology platforms for controlled drug delivery of challenging compounds that significantly improve efficacy, tolerability and compliance. He has authored 25+ research articles in peer-reviewed international journals, 2 book chapters and is an inventor on over 15 patents.
Nilay Patel is a Director of Pre-Formulation & Analytical R&D for the Specialty & complex generics product division at Amneal Pharmaceuticals. He holds a Master’s degree in Pharmaceutical Sciences from Stevens Institute of Technology. Nilay joined Amneal in 2010 as a scientist in the Analytical R&D department and has since progressed through a series of leadership positions within the company. Throughout his tenure at Amneal, Nilay has gained extensive experience working with a wide range of dosage forms, including oral, semisolid, ophthalmic, otic, implants, transdermal, nasal, and inhalation formulations. He has played a pivotal role in suggesting in-vitro alternatives to clinical testing for complex generic products. Currently, he is actively involved in supporting 505(b)(2) programs, focusing on establishing in-vitro models for proprietary gastro-retentive oral dosage forms using multiple approaches.
