He received a masters and Ph.D. from M.I.T. in 1996 and 2001, respectively. His Ph.D. work led to the development of a minimally invasive instrument for measuring solid organ mechanical properties.
His masters work focused on developing a teleoperated laparoscopy system for examining the effects of long distance time lag on surgeon performance.

He currently serves as the senior engineering of the Medical Device and Simulation Laboratory, with particular interests in 3D printing of anatomical models for surgical planning and education, and development of medical devices in support of research and clinical applications.
He joined MGH in 2001 as one of the earliest members of the Simulation Group at CIMIT under Dr. Steven Dawson.  He took on the role of Research Lead for the group in 2007 and Director in 2013, stepping down to focus on engineering efforts and the anatomical 3D printing efforts in 2018.
