Dustin Heldman, PhD

President and COO

Dr. Heldman received his B.S. in Biomedical Engineering from Duke University in 2002 and went on to complete his Ph.D. in Biomedical Engineering at Washington University in St. Louis in 2007. He has a broad background in neural engineering and neurophysiology, with extensive experience in developing algorithms for quantifying movement disorder motor symptoms. He joined the company in 2007 as senior biomedical engineering researcher and is now the President and COO.

Dustin has served or is serving as principal investigator on eight Phase I and four Phase II SBIR grants funded by the National Institutes of Health totaling nearly $9 million. He has served as principal investigator on multi-site clinical trials and been responsible for the preparation of IRB protocols, collection of clinical data, training clinicians, algorithm development, and statistical analysis. Dr. Heldman is currently leading a team of researchers and engineers in the development and clinical evaluation of the next generation of movement analysis systems. A list of Dr. Heldman’s publications can be found on PubMed

Robert Schmidt, JD
