Past and Present Distinguished Postdoctoral Fellows
The Distinguished Postdoctoral Fellows Program
The Jackson School of Geosciences Distinguished Postdoctoral Fellows Program seeks to hire creative and enterprising postdoctoral scholars who will conduct independent research on topics that advance our understanding of Earth as a system while engaging with researchers and faculty across the Jackson School. We welcome applicants with research interests across geosciences disciplines, but we are particularly interested in applicants who want to work at the interfaces between disciplines.

Current Distinguished Postdoctoral Fellows
Ekaterina (Katya) Larina (beginning 2022) received her PhD from the University of Southern California. Ekaterina is an interdisciplinary geoscientist that bridges research between paleoecology, geochemistry, geobiology, sedimentology, and earth-system modeling. Specifically, her expertise includes the investigation of the ammonite ecology, the end-Triassic and the Cretaceous-Paleogene mass extinctions. Ekaterina is interested in ecological and environmental trends during major earth-life perturbation events, and what lessons we can learn to understand the consequences of future warming, ocean acidification, and deoxygenation on marine ecosystems.
Andrew Moodie (beginning 2022) received his PhD from Rice University in Houston, TX. He is a geomorphologist and sedimentologist interested in landscape change at a variety of time and space scales. His research focuses on river and delta environments, which possess an abundance of natural resources that are critical for human life. He primarily uses numerical models to explore how sensitive these environments are to various external processes and forcings. Now (i.e., as a JSG postdoc), he is using numerical modeling to understand the development of rivers and deltas on Mars.
Past Distinguished Postdoctoral Fellows
Kyle Ashley (2015-2017) received his PhD at Virginia Tech. His research is focused on the evolution of metamorphic and igneous systems, applying pseudosection analysis, petrographic assessment, geochronology, and conventional and unconventional thermobarometric techniques to unravel changes in a rock’s pressure, temperature, fluid, mineralogy and deformation across time. Lately, Kyle has been studying the theory and application of trace element thermobarometers (e.g. Ti-in-quartz), as well as making advances in utilizing included minerals in rigid hosts for thermobarometry purposes with the application of elastic theory. He is currently studying rocks from Scotland, Himalayan Mountains (India, Nepal, and Bhutan), Greece, northern Appalachians, the Adirondack Mountains, Australia, Colorado, Lesser Antilles (Caribbean), and Madagascar, and since 2017, he has been a Visiting Assistant Professor at the University of Pittsburgh.
William Foster (2015-2017) received his PhD from the School of Geography, Earth and Environmental Sciences at Plymouth University. William is a paleoecologist primarily interested in the recovery of marine invertebrates following the late Permian mass extinction event. His research focuses on how subsequent environmental change following the late Permian mass extinction led to shifts in the recovery of the benthos and if wave-aerated settings provided a ‘habitable zone’ allowing diverse benthic life, in particular reef ecosystems, to survive and recover following major climate warming. He is currently at Universität Hamburg’s Department of Earth Sciences.
Tim Goudge (2015-2017) received his Ph.D. from Brown University. Tim is a spectroscopist and planetary scientist studying the surface geology of Mars to further understand the planet’s climatic and hydrologic evolution. He is interested in how aqueous surface processes are recorded in both landscape topography/geomorphology, and the mineralogy and stratigraphy of the sedimentary rock record. He is currently a member of the faculty in the Department of Geosciences at the University of Texas at Austin.
Nick Dygert (2014-2016) received his PhD at Brown University. He is a petrologist/geochemist interested in the physical and chemical evolution of the terrestrial and lunar mantles. Nick’s research focuses on mantle melt migration, the thermal history of the upper mantle, petrogenesis of lunar basalts, lunar cumulate mantle overturn, and trace element partitioning in systems relevant to Earth, the Moon, and Mars. Since 2017, he has been a member of the faculty in the Department of Earth and Planetary Sciences at University of Tennessee at Knoxville.
Burch Fisher (2014-2016) received his Ph.D. at the University of California at Santa Barbara. Burch’s research is broadly interested in how landscapes evolve with respect to complex linkages between climate, tectonics, organisms, and humans at the Earth’s surface. To this end, his projects are diverse in both spatial (Himalaya, Andes, North America) and temporal scales (10^0 – 10^6 years) and have generally relied on several distinct data sets to decipher and quantify landscape drivers and signatures, including geochemical (cosmogenic and fallout radionuclides, U-series, etc), topographic (terrestrial and airborne lidar), remotely-sensed (TRMM, ASTER, GeoEye, etc), and field-based observations. In 2016, he accepted a post doc position at the University of Pittsburgh’s Department of Geology and Environmental Science.
Tieyuan Zhu (2014-2016) received his Ph.D. degree from Stanford University in 2014. Tieyuan is an exploration seismologist who seeks to solve challenging energy and environment problems using seismic waves. His interests include advancing understanding of physics of seismic wave propagation in real Earth media, time-reversal, seismic inversion & imaging, time-lapse monitoring, and microseismic. He is now a member of the faculty at Penn State’s College of Earth and Mineral Sciences.
