About
Stephen P. Cavnar is a biomedical engineer whose research centers on advancing three-dimensional (3D) cell culture technologies for high-throughput drug screening and cancer biology. His most-cited work, "Microscale 3D Collagen Cell Culture Assays in Conventional Flat-Bottom 384-Well Plates" (2014, 26 citations), addresses a critical bottleneck in drug development: the transition from traditional 2D monolayers to more physiologically relevant 3D microenvironments. Cavnar pioneered methods to integrate cell-laden collagen hydrogels into standard multiwell plates, enabling scalable, reproducible 3D assays compatible with existing high-throughput screening infrastructure. This innovation bridges the gap between academic research and pharmaceutical applications, allowing researchers to better mimic in vivo tumor microenvironments for drug efficacy testing. His contributions have been cited by groups working on cancer metastasis, tissue engineering, and microfluidic organ-on-chip systems. By simplifying complex 3D culture protocols, Cavnar has empowered labs worldwide to adopt more predictive models, reducing the reliance on animal testing and improving preclinical drug validation. His work exemplifies how engineering solutions can transform biological discovery and therapeutic development.
