PhD Applications welcome on the broad topics of climate impacts of forest change and/or drought and disturbance impacts on ecohydrology and water resources. Applications are invited for a PhD assistantship focused on quantifying carbon, water, and energy flux consequences of temperate forest disturbances and recovery, or examining the ecohydrologic and ecosystem services impacts of land cover change, droughts and natural disturbances. Successful recruits will join the Biogeosciences Research Group of Clark University’s Earth System Science program within the Graduate School of Geography. Experience with terrestrial ecosystem ecology, ecohydrology, biosphere-atmosphere exchange, eddy covariance, EOS remote sensing, and/or ecosystem and hydrologic process modeling is desired.   Send inquiries to Prof. Christopher Williams ( and see application details at Clark University is an Affirmative Action, Equal Opportunity Employer. Minorities and women are strongly encouraged to apply.
