Mr. Kief has extensive background in programmable logic involving FPGA and CPLD technologies. He is currently developing a 1U CubeSat to perform space weather analysis. This satellite will be launched in 2012. Mr. Kief retired from the Air Force in 1998 following 20 years of military service. His final military assignment was at the Air Force Operational Test and Evaluation Center (AFOTEC) at Kirtland Air Force Base.

Mr. Kief has a B.S. and M.S. in Computer Engineering from the University of New Mexico. He has published and taught in the areas of digital and programmable logic and in verification and validation of systems. He is also an IEEE senior member.

Chief Research Officer:
Dr. Steven C. Suddarth
is the Chief Research Officer of COSMIAC. He serves as Research Faculty at the University of New Mexico.

A retired Air Force Colonel with 24 years of service, Dr. Suddarth served his last military assignment as the liaison from U.S. Strategic Command to the National Laboratories. Based in Los Alamos, NM, Col. Suddarth initiated and oversaw a development team of 60 people spanning four sites to develop key technologies for the war fighter. Dr. Suddarth has overseen several substantial computer engineering/embedded systems projects. These include the development of a first-ever 3-dimensional mixed analog/digital image processor which advanced the State-of-the-Art by 3 orders of magnitude. Dr. Suddarth also built and tested several airborne optical sensing systems, unmanned aerial robotics systems, and software systems for large military space programs.

Dr. Suddarth is a 1982 graduate of the U.S. Air Force Academy (B.S. in Electrical Engineering), and he holds M.S. and Ph.D. degrees in Electrical Engineering from the University of Washington. Dr. Suddarth is also a graduate of the Brazilian Air Command and Staff College, U.S. Joint Forces Staff College, and the U.S. Air War College. He has authored over 20 papers.

Dave Alexander

Research Scholar:
Mr. David Alexander
received BSEE and MSEE degrees from the United States Air Force Academy in 1968 and from the University of New Mexico in 1973. He has been an active member of the radiation effects community for 42 years. He has held positions at the Air Force Weapons Laboratory, BDM Corporation, Sandia National Laboratories, Mission Research Corporation, the Institute for Space and Defense Electronics, and the Air Force Research Laboratory. He is currently a consultant for COSMIAC and the University of New Mexico. He has been an active participant in the technical community authoring numerous papers in the IEEE Transactions on Nuclear Science and the Hardened Electronics and Radiation Technology Conference.

Brian Zufelt

Research Engineer:
Mr. Brian Zufelt
is an electrical engineer and graduated from the University of New Mexico. He has written many tutorials over FPGA design utilizing VHDL. He has also assisted many community colleges in the creation of FPGA based curriculum. Over the last three years, Zufelt has been working with the Air Force Research Lab (AFRL) and the COSMIAC to create Space Plug-and-play Architecture (SPA) components, and provided training on SPA tools and architecture. To date, Zufelt has trained over 500 engineers in this new approach to spacecraft design. Recent work involves the use of different types of Mini Plug and Play network managers that can control various Appliqué Sensor Interface Modules. This approach builds on the current SPA-1 standard while remaining ITAR free. This architecture will be flown on the RAMPAT Cubesat mission and the Trailblazer Cubesat mission that are in current development. Trailblazer will be one of the first satellites to completely run on top of the new Plug and Play concept. It will be a 1U Cubesat that is set to launch next fall. It will fly a dosimeter to test the radiation levels of the South Atlantic Anomaly in addition to testing a new type of 3D Printed Circuit Board – rapid prototyping design. Trailblazer will also show the benefit that Plug and Play methodology has on spacecraft design in both development time and cost. The RAMPART mission will include a small Mini Plug and Play network to test different types of ASIMs. This Mini PnP network will contain a set of modules from microcontrollers to FPGAs. Their performance will be tested by taking advantage of RAMPARTs placement within the Van Allen belts and measuring the effects this highly radiated environment will have on the components.

Scientist:
Dr. Dolores A. Black
received her B.S. from the University of New Mexico in 1991, M.S from Vanderbilt University in 2006 and her Ph.D. from Vanderbilt University in 2011 in electrical engineering.  After completing her B.S degree she worked in the aerospace industry in the areas of circuit design, FPGA and ASIC design for 15 years before returning to graduate school.  Her research interest is in soft error rate prediction as it applies to complex digital IC's, FPGA's and ASICs. This included research and development on the radiation effects for a lightly ionizing environment on complex integrated, analyzed the physics of particle interaction of semiconductor materials, developed a methodology and tools to evaluate the effects of an ion strike on a semiconductor using a Monte Carlo Radiative Environment tool, converting the charge deposited into a current threshold resulting in a voltage rail-to-rail strike analyzed via SPICE that would propagate a higher level analysis tool, such as ModelSim resulting in a complex IC’s soft error rate prediction. Her earlier research in accordance with her Master’s work included research and development of VHDL components to develop a hardware-software co-design environment for a Single Processing Platform (SPP). She is a member of IEEE.
