Samuel Odebamowo is a Senior Application Scientist at Lhasa Limited and a former FDA computational toxicologist. He specializes in the application, interpretation, and regulatory acceptance of (Q)SAR models and in silico frameworks for chemical safety assessment. In his role, Samuel plays a key part in translating complex regulatory requirements, such as ICH M7, S1B, and Q3E, into practical, reproducible toxicological workflows that support confident decision making. He also contributes to scientific engagement activities and cross industry collaborations aimed at improving the use of predictive toxicology in regulatory settings. He holds an M.S. in Environmental Toxicology from New York University and is committed to advancing next-generation risk assessment (NGRA) methodologies across the life sciences.
Candice Johnson, Ph.D. is a Senior Research Scientist at Instem. Dr. Johnson has co-authored several peer-reviewed publications and book chapters describing the implementation of in silico approaches and methodologies for gaining confidence in in silico predictions. Her work expands into novel application of in silico approaches and supporting the advancement of alternative methods. She is particularly interested in the application of computational tools to support toxicological evaluations; for example, in the assessment of extractables and leachables.
Josh received his BA in Chemistry from Boston University in 2013, and his PhD in Chemistry from the University of Pennsylvania in 2020. He joined Takeda Pharmaceutical Company in 2020 as part of the Global Material Qualification team in Manufacturing Sciences and Analytical Technology supporting the organization’s manufacturing and pharmaceutical sciences network. Josh helps to harmonize processes to streamline the material qualification process, centralize knowledge, and develop digital tools to help automate workflows. Prior to joining Takeda, Josh has also worked as a QC Chemist, and as a project management consultant for clinical trials focusing on central nervous system disorders.
Dr. Erica Rogers is a board-certified toxicologist and Senior Toxicologist II at Gad Consulting Services, where she has worked since 2017.
