Dr. Weiss is a mechanical engineer specializing in custom mechanical testing, solid mechanics, soft materials, and biomanufacturing. He is experienced in mechatronics and additive manufacturing, with particular focus on fused filament fabrication, stereolithography, and 3D printing of single cells and organoids. Through his work, he has led multidisciplinary projects at the intersection of engineering and the life sciences, driving solutions that bridge fundamental research and real-world applications.

Before joining Exponent, Dr. Weiss received his Ph.D. in bioengineering at Stanford University, where he developed an open-source, multi-material 3D bioprinter platform, including novel multi-nozzle printheads that significantly improve throughput of tissue fabrication. Using these technologies, he engineered stem cell-derived heart tissues, investigated differentiation and maturation strategies for therapeutic applications, fabricated acellular trileaflet heart valves with photocurable hydrogels, and characterized auxetic lattices constructed from soft silicone materials.

Dr. Weiss' prior work includes research in microfluidics, where he designed single-cell capture devices for studying the molecular mechanisms of cardiomyopathies while completing his B.S. in biomedical engineering at Yale University.
