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.

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. Dr. Chen’s research includes Martian dust simulation studies and researching the design of high altitude diffusers for space shuttle main engines. He also has worked on the NASA project CODEM, where he designed and tested prototype hardware and simulation software.
