Mission
The Society for Pharmaceutical Dissolution Science was originally formed on July 16, 2012 in Mumbai, India. Gradually growing over the years, SPDS decided in 2018 to expand internationally to the USA. The US Chapter coordinates with the Indian parent society while operating as a wholly independent not-for-profit organization incorporated in the USA. Membership in any chapter of SPDS grants members reciprocal membership benefits in all chapters. Member benefits include discounts to any and all SPDS conferences and workshops. SPDS aspires to be the most prominent professional society focused solely on pharmaceutical dissolution science. Our mission is to support progress in and disseminate information pertaining to the on-going advancement of pharmaceutical dissolution science across industry and academia worldwide.
About The Organization
SPDS US Chapter is incorporated as a non-for-profit US corporation. The Board of Directors for SPDS US is a volunteer group which manages the business aspects of the non-for-profit society including such things as the annual meeting, annual report, and tax filings. The Scientific Steering Committee is a volunteer group that determines and directs all scientific content including programming, conferences, training sessions, and membership outreach.
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.
