Bart Bortnik, PhD
Project Scientist

Bart Bortnik, PhD, received his doctorate in Photonics from the Electrical Engineering Department of UCLA in 2007. He subsequently led the team at JPL/NASA responsible for the space-grade Optics/Fiber/Laser assembly of the OPALS project, a laser-based optical communications technology demonstration which was launched and installed onto the International Space Station. He has authored or co-authored over 20 publications and conference proceedings. In his spare time, Bortnik enjoys machining metal parts and assembling automated CNC lens grinding and polishing machinery for the fabrication of microoptical elements for endoscope applications.

David Scott Kittle, PhD
Project Scientist

David Scott Kittle received his doctorate from the Department of Electrical and Computer Engineering at Duke University in May 2013, where he worked on computational imaging systems under David J. Brady, PhD. Kittle received his bachelor's degree in Systems Engineering from Walla Walla University in 2005. He worked for the Loma Linda University Department of Radiation Medicine under Robert Pearlstein, MD (Neurosurgery, Duke University School of Medicine), prior to beginning graduate school at Duke University. Kittle joined the Department of Neurosurgery under Keith Black, MD, at Cedars-Sinai in September 2013.
