Prof. Robert C. ChangPrincipal InvestigatorRobert Chang received his B.S. from The University of Pennsylvania and Ph.D. in Mechanical Engineering from Drexel University with a research focus in computer-aided tissue engineering. His doctoral dissertation centered on the development of biofabrication systems to create reproducible, biomimetic 3D micro-organs as a high-throughput in vitro radiation/drug model for NASA's exploration in planetary environments. He received a National Research Council (NRC) Research Fellowship to work as a biomechanical engineer in the Physical Measurement Laboratory at the National Institute of Standards and Technology (NIST) where he has engineered novel tissue models towards the validation of depth-resolving optical modalities including optical coherent tomography (OCT) and confocal microscopy for dimensional metrology as well as hyperspectral imaging for wound healing applications and surgical scenes. Robert is currently an Assistant Professor in the Mechanical Engineering Department at Stevensm, where his research interests are in biofabrication, biomodeling, and measurement of biotissues.

PHD Students
Ralf Zgeib (Google Scholar - LinkedIn - GitHub)Bio:
Ralf Zgeib is a mechanical‑engineering researcher whose career began with a B.E. in Notre Dame University-Lebanon and has since encompassed industry roles, entrepreneurship, and doctoral work in the United States. He specializes in gradient multi‑material bioprinting, designing next‑generation 3D bioprinting systems such as a modular quad‑extrusion platform paired with an in‑situ rheometric module that fuses load‑cell force data and pressure sensing to calculate real‑time viscosity of non‑Newtonian bioinks during deposition. These integrated hardware–software tools underpin his efforts to fabricate spatially precise hydrogel constructs and to create rigorous in‑vitro models of cell–cell and cell-matrix interactions.
