D. Marshall Porterfield
Director, Space Life and Physical Sciences
Dr. D. Marshall Porterfield is now serving as Division Director for Space Life and Physical Sciences in the Human Exploration and Operations Mission Directorate at NASA headquarters in Washington DC. The division includes the Human Research Program, the Physical Sciences Program, and the Space Biology Program, as well as acting as the liaison for the ISS National Lab. The SLPS program includes responsibility for managing all extramural grants and research, as well as the intramural research and engineering assets at six NASA centers. Currently the programmatic focus is on ISS utilization. Dr. Porterfield is on official leave from Purdue University where he is a Professor of Biological Engineering.His teaching and research focus is on advanced physiological sensing technologies for research applications in biology, agriculture, the environment, and medicine. Several of his recent projects involve scanning probe sensor technology, biosensors, bio-MEMS, bio-nanotechnology, and lab-on-a-chip systems. He also is working on understanding how living systems adapt and respond to the spaceflight environment. His work in gravitational and space biology includes cell signaling, biophysical limitations in microgravity, nutrient delivery technology, and biomimetic sensors. He was recognized by the American Society for Gravitational and Space Biology in 2007 with the Halstead Young Investigator Award. Overall his research work at Purdue was recognized by the University Faculty Scholar Award, the University’s top mid career research distinction. His work includes publishing over 100 peer reviewed manuscripts, papers, technical publications, patents, and book chapters; he has also delivered almost 100 invited presentations.His leadership activity includes service as President of the American Society for Gravitational and Space Biology, and he was also recently elected to serve as President for the Institute for Biological Engineering.Dr. Porterfield’s work in the field of biological engineering was recently recognized by election to the College of Fellows for the American Institute for Medical and Biological Engineering, an honor reserved forthe top 2% of medical and biological engineers in US. He was cited for his work \\\\\\\"bridging the interface between engineering and physiology through outstanding contributions to biosensor technology and fundamental cell biology.\\\\\\\"
Advanced physiological sensing technologies for research applications in biology, agriculture, and medicine. Specific projects include: scanning probe sensor technology, biosensors, bioMEMS, bionanotechnology, and lab-on-a-chip systems. He also is working with plant systems in bioregenerative life support systems for spaceflight. His work in this area includes cell signaling, biophysical limitations in microgravity, nutrient delivery technology, and biomimetic sensors.
