The Terrestrial Ecosystem Science (TES) program advances fundamental understanding of environmental processes through recognition and collaboration with other U.S. Department of Energy (DOE) programs and user facilities. These include the related Subsurface Biogeochemical Research program, which studies biogeochemical structure and function of subsurface environments. Linkages include other research programs and DOE scientific user facilities within the Office of Biological and Environmental Research (BER) and other parts of the Office of Science.
DOE's Office of Science oversees the construction and operation of some of the nation's most advanced research and development user facilities, located at national laboratories and universities. These state-of-the-art facilities are shared with the science community worldwide and offer some technologies and instrumentation that are available nowhere else. Guidelines for submitting proposals for access to these facilities are available from the individual centers.
The TES program currently supports a postdoctoral research assistant position at EMSL to facilitate linking the TES program within the Terrestrial and Subsurface Science Theme. Dr. Malak Tfaily is the current postdoctoral research assistant in EMSL's mass spectrometry group. She has been assisting EMSL users in implementing next-generation, state-of-the-art mass spectrometry and infrared and fluorescence spectroscopy techniques to understand carbon cycling in the environment. Dr. Tfaily has extensive experience especially in applying ion cyclotron resonance mass spectrometry to characterize organic matter composition from different terrestrial and aquatic systems, and helping users interpret these data to enrich the understanding of biotic and abiotic processes that impact carbon dynamics such as microbial respiration, photo degradation, and anthropogenic activities. She is also interested in investigating the effect of climate change on carbon dynamics in the terrestrial ecosystem. Dr. Tfaily has recently developed extraction protocols for the characterization of carbon compounds in soil organic matter, thereby providing the chemical and structural detail needed to develop mechanistic descriptions of soil carbon flow processes. In addition to her current research, Dr. Tfaily seeks to leverage EMSL capabilities within the TES program.
