Dr. Shen is among those who develop new methods and instruments filling the big gap between demand and supply in healthcare training and medical education. During the past decade, his research and development energies have been dedicated to a few interdisciplinary teams striving to build computer-based virtual surgery simulation platforms and provide trainees better curricula to achieve rapid clinical proficiency leading to excellent clinical outcomes. One example of these initiatives is the laser BPH surgery trainer created by the team at the Center for Research in Education and Simulation Technologies (CREST). The simulation engine of the virtual trainer is built on a set of robust and fast algorithms integrated from their original work. These algorithms provide lifelike realism as well as sustain extreme conditions that could be imposed by arbitrary manipulations from users. The curriculum is guided by a clinical advisory panel consisting of Drs. Robert Sweet, Carson Wang, Claus Roehrborn and Cully Carson. By May 2011, this virtual trainer had been verified by over 60 board-certificated surgeons in two validation studies.
As a principle developer in various modeling and simulation projects, Shen’s work ranges from solution deriving, system architecting to source-code implementation of computation modules such as soft tissue deformation and dissection, collision detection and contact modeling, haptic rendering and visualization. His earlier BME training includes medical image and signal processing, medical signal analysis and system control, and bioinstrumentation.
Before joining CREST, he worked as a research assistant/associate in the Biomedical Engineering Programs at Zhejiang University, University of Texas Southwestern Medical Center at Dallas and University of Texas at Arlington.
