He has published over 150 scientific papers and been invited to participate in international scientific conferences. He has been the recipient of numerous research grants from NSF, from NASA, and from private foundations. Dr. Calle received the NASA Exceptional Technological Achievement Medal, the NASA Spaceflight Awareness Award for his outstanding contributions to the space program, and the NASA Silver Snoopy Award for his exceptional contributions to human spaceflight. He is the author of Superstrings and Other Things: A Guide to Physics, Second Edition, Taylor & Francis (2009), Einstein for Dummies, Wiley (2005), Coffee with Einstein, Duncan Baird (2008), and The Universe, Prometheus Books (2009). His books have been translated into French, Spanish, Dutch, German, and Serbian.

Dr. Charles BuhlerDr. Charles Buhler received his B.S. in Engineering Physics from Embry-Riddle Aeronautical University in 1995. He then pursued his M.S and Ph.D degrees in Theoretical Condensed Matter Physics from Florida State University while working at the National High Magnetic Field Laboratory. His research focused on the physics of High Temperataure Superconductors. Soon after graduating, he began working at the EMPL as a postdoctoral scientist and is currently working on trying to understand the electrostatic nature of Martian and lunar soil simulants. He is responsible for overseeing graduate student research while performing experiments in simulated Martian environments to test and develop future instrumentation for a Mars Landing mission.

He is currently working on the development of dust mitigation technologies for the moon and Mars.


Sarah SnyderSarah Snyder graduated from Florida Institute of Technology in 2005 with a B.S. in Physics and a B.S. in Space Sciences. Since that time, she has worked on Project SHORE with Florida Space Research Institute and with ASRC Aerospace in the Transducer Development Lab prior to joining the Electrostatics and Surface Physics Lab in December 2007. She is currently working on her M.S. degree in Space Sciences at the Florida Institute of Technology.


Steve TrigwellDr. Steve Trigwell is a senior research scientist in the Electrostatics and Surface Physics Laboratory. He received his B.Sc. in Physics from Leicester University in England, his M.S. in Materials Engineering from San Jose State University, and his Ph.D. in Applied Science from the University of Arkansas at Little Rock. Prior to joining KSC, he held positions as a Scientist in the Materials Science and Characterization Group at Raychem Corporation, and as the Laboratory Director for the Auger Electron Spectroscopy Lab at Surface Science Laboratories in California. His current research interests include atmospheric plasma glow discharge (APGD) modification of material surfaces for space applications, investigation of the tribocharging properties of simulated Lunar and Mars dust, and characterization of modified nanomaterials.

SidClementsDr. Sid Clements is a professor of Physics at Appalachian State University and a faculty fellow in the Electrostatics and Surface Physics Laboratory. Dr. Clements obtained his Ph.D. in physics from Florida State University where he was a postdoctoral fellow and a research professor for 10 years. In 1988, he joined the department of physics and astronomy at ASU. He joined our NASA laboratory in 2003 as a NASA Summer Faculty Fellow and has continued a collaborative research effort since. He has conducted research on the charging of high-resistivity aerosols by ions and/or electrons produced by corona discharge. The main applications of this research are electrostatic precipitation of pollutants and electrostatic painting. His current research efforts with NASA involve both electrostatic applications and electrostatic hazards in the space program, including those in the Space Shuttle, International Space Station, and the exploration of the moon and Mars.

Dr. Albert Chen is a professor of Physics at Oklahoma Baptist University and a faculty fellow in the Electrostatics and Surface Physics Laboratory. Dr. Chen obtained his Ph.D. in physics from Baylor University. He joined the ESPL in 2002 as a NASA Summer Faculty Felow, after serving in the same capacity at Stennis Space Center, Mississippi, Johnson Space Center in Houston, Texas, and Dryden Flight Research Center in the engineering research division in Edwards, California.
