Arno Tilles

Dr. Tilles was born in Hollywood, Florida in January 1959.  He received a BS degree in Biology (1979), a BS degree in Mechanical Engineering (1981), and an MS degree in Biomedical Engineering (1985), all from the University of Miami.  He also received his MD degree from the University of Miami School of Medicine in 1993. 

After completing an internship and residency in Internal Medicine at the University of Miami/Jackson Memorial Hospital, Dr. Tilles was appointed a research fellow in the Biomedical Engineering Research and Education (BERE) Program at the CEM.  In 2001, he was promoted to Instructor in Surgery and Bioengineering at Harvard Medical School.  Dr. Tilles is a licensed physician in Massachusetts and Florida, and is board certified in Internal Medicine by the American Board of Internal Medicine.  Dr. Tilles serves as the coordinator of the weekly “Seminar Series in Biomedical Science and Engineering” at the CEM.

Dr. Tilles’ research focuses on the application of metabolic and tissue engineering principles to the optimization of biomedical devices which can be integrated with the host and perform as designed.  The goal is to develop a bioartificial liver device in which cultured hepatocytes can maintain long-term, differentiated liver-specific functions.  Methods utilized include preconditioning hepatocytes to optimize functions at the cellular level, as well as microfabrication and cell micropatterning techniques to optimize hepatocyte functions at the tissue level.  His research also involves developing protocols for differentiating embryonic stem cells into a pure population of mature hepatocytes.
