Biomedical Engineering & Organic Bioelectronics Leader | Neural Interfaces, Medical Devices & Materials–Tissue Interaction | Expert Witness in Product Safety & Failure Analysis

Overview

Multidisciplinary biomedical, mechanical, and materials engineer with a career bridging advanced materials science, neural engineering, and medical device innovation. Work focuses on designing and characterizing organic semiconductors, conducting polymers, hydrogels, and composite systems that interface safely and effectively with neural and other biological tissues. Extensive experience integrating analytical techniques, such as TEM, SEM/EDS, PLM, AFM, and XRD, with in vitro and in vivo studies to understand how material chemistry, morphology, and biopersistence drive biological responses. Regularly supports litigation, regulatory evaluations, and product development by translating complex data into objective, scientifically grounded opinions on product safety, contamination, and failure mechanisms. Academic leadership includes directing NIH- and NSF-funded programs, mentoring numerous trainees, and shaping the field of organic bioelectronics through publications, patents, and conference and editorial roles.
