Andrew C. Ahn, MD, MPH is an Assistant Professor of Medicine and Radiology within the Hospital Medicine Program  at Beth Israel Deaconess Medical Center and Massachusetts General Hospital Martinos Center for Biomedical Imaging.  In 2005, he was awarded an NIH sponsored K-23 Career Development Award entitled “The Biophysics of Acupuncture: The Electrical Properties of Loose Connective Tissue”.  As part of this award, he became proficient in biological engineering by taking numerous graduate level courses at MIT and has explored applications of engineering principles to medicine and physiology. He has researched the role of collagen piezoelectricity, electrokinetics of blood and fluid flow, the electrical properties of loose connective tissue, the use of Scanning Kelvin Probe for measure of skin electrical potential, and aortic input impedance in hypertension.  He has redirected his efforts toward the mathematical analyses of physiologic waveforms and use of computational methods for clinical medicine.  He is the Lead Medical Adviser for the Dynamical Biomarkers Group.
