Student Research Opportunity

PhD position in critical zone processes. This position will be filled by an exceptional student with interest in connections between geomorphology, geochemistry, and ecology. Students with a strong track record of research are especially encouraged to apply. Applicants will be competing for an assistantship begininning in the 2015-2016 academic year. The assistantship covers tuition, a stipend for the academic year, and eligibility for summer support. The successful applicant will conduct cross-disciplinary research on linkages between bedrock composition, regolith development, forest structure, and landscape evolution across the Southern Sierra Critical Zone Observatory. The project builds on work summarized in an article recently published by my research group. It fits well with other research on ecosystem function in the CZO network and offers many opportunities for cross-institutional networking with world-class students and scientists from a broad range of disciplines in Earth systems science. Hence it provides an excellent platform for launching a career in a research field that is vital to understanding the implications of human activities in our warming and increasingly populated world. Interested students should apply for the position via UW's standard graduate application process. Please include specific reference to this opportunity and list me as your prospective advisor when applying. Applicants are advised to contact me by e-mail or by phone before submitting an application for more details about the project.

When you contact me, please provide the following:
  • a current curriculum vitae or resume;
  • a one-page statement of interest in graduate studies in my research group;
  • a copy of your academic transcript(s) – unofficial copies (e.g., screenshots) are OK at this stage;
  • if available, your most recent GRE scores; &
  • an example of your scientific writing (e.g., your master's thesis), if available.
