Dr. Ritter'’s current research interests are in Mathematical Modeling of Physiological Systems, Angiotensin Converting Enzyme (ACE) and Cardiac Myocytes, The Failing Heart, Pulsatile Flow in Distensible Vessels, Rotary Protein Motors, and Robotic and Minimally Invasive Surgery.

He is working on nano-robotics and developing a biological battery that runs on glucose. The concept is a battery that can be implanted and run without replacement. Current implantable motors and medical devices such as artificial hearts require energy sources such as batteries that deplete, which requires replacement. Ritter’s goal is to create a battery that can overcome these current limitations.

Dr. Ritter is a pioneer in the biomedical field, and has played an integral role in the growth of the program at Stevens. He is the co-author of over 40 publications in peer reviewed journals and numerous abstracts and presentations at local, national and international conferences. He is the primary author of a recent undergraduate textbook in Biomedical Engineering.

He has been the PI or Co-PI on grants from NSF, NIH, AHA and New Jersey Commission on Science and Technology, is a member of ASEE and BMES, and has been awarded a patent No. 6,324,419. 2001, Inventors: A. Nejat Guzelsu, Thomas W. Findley, John Federici, Hans Chaudhry, Arthur B. Ritter. Title: Apparatus and Method for Non-Invasive Measurement of Stretch.
