Mark Rosker, Director of DARPA MTO

Mark Rosker has served as the director of the Defense Advanced Research Projects Agency's Microsystems Technology Office since April 2018. He was a program manager in the office from 2003 to 2011.

The MTO's core objective is to develop intelligence microsystems and next-generation components in the areas of command, control, communications, computing, intelligence, surveillance and reconnaissance; electronic warfare; and directed energy. 

As a program manager, Rosker developed a portfolio of technical programs in gallium nitride and other compound semiconductor radio-frequency devices, heterogenous circuit integration, terahertz electronics and quantum cascade lasers.

Rosker's Wide Band Gap Semiconductors for Radio Frequency Applications program was honored in 2016 with the DARPA Game-Changer Award. 

He previously also served as the deputy director of DARPA's Defense Sciences Office, which pursues high-payoff research initiatives in science and engineering disciplines related to national security technologies. 

Prior to his most recent DARPA role, Rosker served as a principal engineering fellow at Raytheon's space and airborne system division based in Rosslyn, Virginia. 

Earlier in his career, he worked in NASA's Jet Propulsion Laboratory, where he was part of a team that pursued submillimeter-wave advanced technologies.

He also worked at Rockwell Scientific, now Teledyne Scientific, where he researched photorefractive oscillators and visible and infrared frequency conversion materials and devices, time-domain spectroscopy of materials and optical power limiters, among other nonlinear optics disciplines. 

Rosker earned a bachelor's degree in physics from the California Institute of Technology and both a master's degree and a doctorate in applied and engineering physics from Cornell University.

In 2012, the Institute of Electrical and Electronics Engineers selected Rosker as a fellow for “his leadership in microwave and millimeter-wave phased arrays, gallium nitride semiconductors and terahertz electronics.”
