Christopher Bettinger is a Professor at Carnegie Mellon University in the Departments of Materials Science and Engineering and Biomedical Engineering. He directs the laboratory for Biomaterials-based Microsystems and Electronics at CMU, which designs materials and interfaces to integrate medical devices with the human body. Chris has published over 80 articles and has been issued over 10 patents. Chris has received honors including the National Academy of Sciences Award for Initiatives in Research, the MIT Tech Review TR35 Top Young Innovator under 35, and the DARPA Young Investigator Award.  Prof. Bettinger is also a co-inventor on several patents and Co-Founder and CTO of Ancure, an early stage medical device company. Prof. Bettinger received an S.B. in Chemical Engineering, an M.Eng. in Biomedical Engineering, and a Ph.D. in Materials Science and Engineering as a Charles Stark Draper Fellow, all from the Massachusetts Institute of Technology.  He completed his post-doctoral fellowship at Stanford University in the Department of Chemical Engineering as an NIH Ruth Kirschstein Fellow.


Ph.D., Massachusetts Institute of Technology, 2008


The mission of the Bettinger Group at CMU is to design, synthesize, and process synthetic polymers into medical devices for use in neurotechnology. We bring to bear expertise in polymeric biomaterials and flexible electronics for use in next-generation medical devices that can integrate seamlessly with excitable tissue in the human body. Representative examples of our work includes the following: (1) design and synthesis of novel materials and devices to improve the reliability of neural interfaces; (2) the use of flexible electronics for non-conventional neural interfaces; (3) adhesives for use in soft electronics and surgical materials. We work towards this goal by investigating fundamental properties of polymers and then applying these discoveries to design new types of flexible electronic devices. If successful, the innovations in materials and devices could fundamentally improve our ability to sense and modulate the nervous system to diagnose disease or administer new treatment paradigms.
