Jeffrey T. Borenstein is Laboratory Technical Staff at the Charles Stark Draper Laboratory in Cambridge, Massachusetts, USA. Dr. Borenstein is a Technical Director for several of Draper’s programs in artificial organs, tissue engineering and implantable devices. His expertise is in MEMS fabrication technology, biological microsystems and the development of microdevices for therapeutic clinical applications. Dr. Borenstein currently serves as Principal Investigator for projects involving the application of microsystems technology towards engineered tissue constructs for organ assist devices and drug discovery, as well as implantable drug delivery systems for hearing loss and other diseases. These programs are funded by the Department of Defense, the National Institutes of Health and several commercial sponsors. Vishal Tandon is a Research Fellow at the Biomedical Engineering Center, Draper University, USA. His research focuses on the design and testing of implantable microfluidic devices for drug delivery into the ear. Sarah Tao is Senior Manager, New Technologies at CooperVision, Inc. She was previously Senior Member Technical Staff, MEMS Design Group at Draper University, and Research Professor Equivalent, Bioengineering and Therapeutic Sciences at the University of California, San Francisco, USA. Her research interests lie in the areas of biomaterials, nanotechnology, regenerative medicine, drug delivery, BioMEMS, microfluidics and cell culture. Dr. Charest is director of in vitro model and organ-assist work at Draper Laboratory. The work of his teams leverages micro- and nano-fabrication along with advanced machining techniques to create systems which recapitulate native tissue and organ architecture, morphology, and function in vitro. The systems span applications from medical devices to screening platforms for pharmaceuticals, and impact fields of use in various organ and tissue types such as tumor, kidney, vascular tissue and lung. Dr. Charest graduated from Georgia Tech with an MS and PhD in Mechanical Engineering and from Penn State with a BS in Mechanical Engineering.
