Principal Investigator

Mark A. Skylar-Scott, PhD
Assistant Professor, Bioengineering
Basic Science and Engineering (BASE) Initiative at the Betty Irene Moore Children’s Heart Center

Mark received his B.A. and M.Eng in Engineering at Cambridge University (Sidney Sussex College) in the UK in 2007. Under the supervision of Professor Mehmet Fatih Yanik at MIT from 2007-2012, Mark’s Ph.D. in Medical and Electrical Engineering involved the creation of new methods to use femtosecond lasers to print protein structures in 2D and 3D to direct neural and endothelial cell development. After his Ph.D., Mark had a brief foray into the startup world at Formlabs, where he developed and tested 3D printer resins for the Form 1 stereolithography printer. Mark performed his postdoctoral research from 2013-2020 with Jennifer Lewis at Harvard, where he developed new methods of manufacturing vascularized biological tissues, organoids, soft robotics, and metals. Mark is now a member of Stanford’s Basic Science and Engineering (BASE) Initiative of the Children’s Heart Center, where he aims to develop integrative strategies for billion- and trillion-cell bioprinting towards therapeutic scale and whole-organ biomanufacturing.

Research Staff and Scholars

Stacey Lee, PhD
Life Science Research Professional 3

Stacey received her B.S. in Chemical Engineering, with an additional major in Biomedical Engineering from Carnegie Mellon University. Under the supervision of Professor Sanjay Kumar, she earned her Ph.D. at the UC Berkeley-UCSF Graduate Program in Bioengineering. Her dissertation focused on understanding the biophysics of cell motility by combining single-cell micropatterning and femtosecond laser nanosurgery of the actin cytoskeleton. After her Ph.D. and postdoctoral studies in Dr. Kumar’s lab, she worked as a software developer at a biotech startup. At the Skylar-Scott lab, Stacey is working on developing microvascularized tissues.
