Dr. Brad Ringeisen

Dr. Brad Ringeisen joined DARPA as the Deputy Director of BTO in December 2016.


Before DARPA, Dr. Ringeisen was the Head of the Bioenergy and Biofabrication Section at the U.S. Naval Research Laboratory (NRL) where he oversaw diverse research programs including the development and application of laser-assisted printing approaches to biology, development of organs-on-a-chip, microbial energy harvesting and extracellular electron transfer, as well as microbial discovery and microbiome characterization. He was also the Chief Technology Officer for the Defense Department's Advanced Technology Biofabrication Manufacturing Innovation Institute.


From 2012 to 2014, Dr. Ringeisen was detailed at the Defense Threat Reduction Agency (DTRA) Joint Science and Technology Office as a science and technology manager, where he oversaw the development of field-forward diagnostic technology with wireless connectivity to the cloud.


Dr. Ringeisen is a pioneer in the field of live cell printing, having demonstrated the first living bacteria and mammalian cell printing experiment using modified laser-induced forward transfer (LIFT) technology in the early 2000s. He is a named inventor on thirteen patents, eight involving modifications to LIFT for biological applications. He has published more than 60 peer-reviewed manuscripts and has edited a book on cell and organ printing.


Dr. Ringeisen received a Doctor of Philosophy degree in Physical Chemistry from the University of Wisconsin-Madison and a Bachelor of Science degree in Chemistry from Wake Forest University. /p>
