You will use multiple approaches, including laboratory and field measurements and modeling, to characterize the physiological response of microorganisms (both site-derived isolates and whole communities) to hydrological perturbation within the tropics. The central objective of the proposed work is motivated by two critical uncertainties concerning the short- and long-term stability of soil organic matter (SOM): <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.5pt;font-family:"Optima",serif'>• What are the microbial mechanisms that lead to the formation and evolution of SOM, and contribute to its stability and persistence?<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.5pt;font-family:"Optima",serif'>• How are these processes affected by hydrological perturbation. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.5pt;font-family:"Optima",serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.5pt;font-family:"Optima",serif'>The project will employ multi-scale laboratory and field experiments to manipulate the soil pore water in a manner consistent with soil drying. Laboratory experiments will include the design and fabrication of microfluidic devices abstracting the soil pore structure and replicating the heterogeneity of soil chemical gradients and temporal perturbation. Further soil microcosms will establish whole community responses to soil drying and provide better connections to a drought experiment being conducted by project collaborators in Panama. The response of the microbial community and individual isolates to hydrological perturbation will be assessed using infrared spectroscopy and detailed genomic and metabolomic approaches, and feedbacks to soil organic matter formation evaluated using geochemical analyses (including spectroscopy). This project will leverage facilities available at Lawrence Berkeley National Laboratory (including the Advanced Light Source), and work closely with collaborators at the Berkeley Synchrotron Infrared Structural Biology (BSISB) group, UCLA, and the Smithsonian Tropical Forest Institute. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.5pt;font-family:"Optima",serif'><o:p> </o:p></span></p><p class=MsoNormal><b><span style='font-size:11.5pt;font-family:"Optima",serif'>What You Will Do:</span></b><span style='font-size:11.5pt;font-family:"Optima",serif'><o:p></o:p></span></p><p class=MsoNormal><b><span style='font-size:11.5pt;font-family:"Optima",serif'>• </span></b><span style='font-size:11.5pt;font-family:"Optima",serif'>Use multiple approaches, including laboratory and field measurements and modeling, to characterize the physiological response of microorganisms (both site-derived isolates and whole communities) to hydrological perturbation within the tropics.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.5pt;font-family:"Optima",serif'>• Employ multi-scale laboratory and field experiments to manipulate the soil pore water. <o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.5pt;font-family:"Optima",serif'>• Design and fabricate microfluidic devices abstracting the soil pore structure and replicating the heterogeneity of soil chemical gradients and temporal perturbation.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.5pt;font-family:"Optima",serif'>• Communicate regularly and work with other researchers on this project in order to facilitate progress toward program goals.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.5pt;font-family:"Optima",serif'>• Work carefully but efficiently in order to meet project goals in a timely manner.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.5pt;font-family:"Optima",serif'>• Publish research results in peer-reviewed journals.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.5pt;font-family:"Optima",serif'>• Present research results to internal groups and at large national and international meetings.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.5pt;font-family:"Optima",serif'>• Work within an interdisciplinary team of soil scientists, biogeochemists, microbiologists, and modelers.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.5pt;font-family:"Optima",serif'><o:p> </o:p></span></p><p class=MsoNormal><b><span style='font-size:11.5pt;font-family:"Optima",serif'>Additional Responsibilities as needed:</span></b><span style='font-size:11.5pt;font-family:"Optima",serif'><o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.5pt;font-family:"Optima",serif'>• Dynamic energy budget modeling.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.5pt;font-family:"Optima",serif'><o:p> </o:p></span></p><p class=MsoNormal><b><span style='font-size:11.5pt;font-family:"Optima",serif'>What is Required: </span></b><span style='font-size:11.5pt;font-family:"Optima",serif'><o:p></o:p></span></p><p class=MsoNormal><b><span style='font-size:11.5pt;font-family:"Optima",serif'>• </span></b><span style='font-size:11.5pt;font-family:"Optima",serif'>Ph.D in Earth Science, Soil Science, Environmental Microbiology, Environmental Chemistry, Biogeochemistry or a closely related field.
