JASON J. AMSDEN
DUKE UNIVERSITY | Steering Committee
Jason is an associate research professor in the department of electrical and computer engineering at Duke University. Jason received his PhD in physics from Boston University and did postdoctoral work at Tufts University and Seoul National University. At Duke, Jason focuses on the application of computational and compressive techniques to improve spectroscopic instrument design. Conventional spectroscopic instruments are designed such that the instrument response is a delta function and the measurements are essentially the desired spectrum. However, this design approach can limit the spectrometer performance. Jason and his team use a different approach by designing the system response to maximize parameters of interest such as throughput and resolution, and then computationally deconvolve the system response from the measurements to achieve a spectrum – thus improving instrument performance.

He earned his BS (1999) in Agricultural Sciences from the Aristotle University of Thessaloniki, Greece and his PhD (2004) from the Center for Microbial Ecology at Michigan State University, under the supervision of James Tiedje. Prior to joining the faculty at Georgia Tech, he was a Postdoctoral Fellow in the Department of Civil and Environmental Engineering at MIT under the supervision of Ed DeLong.

Dr. William Sparks obtained his Ph.D. in 1982 from the University of Wales, UK (now Cardiff University). He was a research astronomer at the Space Telescope Science Institute in Baltimore for over 30 years and is now a senior researcher at the SETI Institute. From an initial interest in the optical properties and physics of radio galaxies, galaxy clusters and their interstellar medium, his research has moved into astrobiology, exoplanet detection and characterization and the search for life. He showed microbial life can be detected remotely using circular polarization, a diagnostic of homochirality, and patented new types of polarimeter, well-suited to the task. He used the Hubble Space Telescope to search for plumes on Europa, which may offer the prospect of easier access to the liquid subsurface of Europa and a candidate location to seek evidence of extant life beyond Earth. Dr. Sparks is now leading an exobiology program to determine the ultraviolet circular polarization properties of microbial life; exploring the use of light echoes from M dwarf stellar flares as a means to detect and characterize exoplanets; and developing an innovative polarimeter through a newly formed LLC.

Dr. David Stillman is a near surface geophysicist with experience in planetary, oil, and environmental exploration. He has over a decade of experience performing electrical properties measurements at cold temperatures and conducting field geophysical surveys (primarily GPR, spectral induced polarization, resistivity, & EM-induction). His laboratory research focuses on electrical properties measurements of Martian, Europan, and Lunar analogs as a function of temperature, frequency, water/ice content, salinity, humidity, and microbial content. The purpose of these measurements is to determine radar loss and to create a library of dielectric relaxations that can be used to detect and characterize subsurface ice, unfrozen water, and life throughout the Solar System. Currently, Stillman and his colleagues are using electrical property and nuclear magnetic resonance measurements of salt-doped ice and ice-regolith mixtures to determine how ice-binding extracellular proteins change the microstructural properties of liquid vein networks. Additionally, they will determine if such changes could be detected by measuring the bulk electrical resistivity of the icy unit. Stillman also performs laboratory measurements with to measure the metastability of brine, including determining when deliquescence and efflorescence occurs. The laboratory results are then used to produce more accurate models to predict when brine formation occurs on Mars and also determine the water activity of such brine. David has been applying his laboratory knowledge of ice-water phase transitions of brines and his hydrology background to investigate the flow and recharge mechanism of Martian recurring slope lineae (RSL). He has been using spacecraft data to test his theories on RSL formation and recharge. Highlights include the discovery of (1) seasonal differences of RSL regions (2) interannual variations of RSL, (3) water budgets of all RSL demonstrate a RSL are likely not recharged via the water-poor atmosphere, and (4) recharge of northern mid-latitude RSL are consistent with a briny aquifer.
