organized by the Environmental Protection Agency in 2013. The UCFR project began in 2017, is a large collaborative endeavor, sponsored by the National Science Foundation Long Term Research in Environmental Biology program, and joins chemists, aquatic ecologists, and biologists across four US institutions to learn how the UCFR is responding to major restoration efforts. The position will be based at the University of North Texas, under the supervision of Dr. Juliana D’Andrilli and cannot be conducted from a remote location. The student is expected to participate in Ph.D. coursework, research, committee engagement, conferences, Montana collaborative project meetings and field work, and potentially mentor other research scholars. While the research focus is set with using bulk-level dissolved organic matter characterization techniques, other opportunities to learn other analytical chemistry instruments may be available, e.g., atomic absorption spectroscopy and/or inductively coupled plasma mass spectrometry for metal identification and concentration analysis. Travel is expected for conference attendance, project meetings, and field work. This position requires laboratory, field, and computer work, successful completion of coursework and Ph.D. dissertation, writing manuscripts for publication, giving presentations, and outreach. Applicants that are curious about ecosystem function and how changes at the microscopic level influence river networks are particularly encouraged to apply. Previous chemistry and/or biology laboratory experience is required as the position involves responsible and appropriate handling of glassware and meticulous use of analytical chemistry instruments. Applicants with field work experience are encouraged to apply, though previous field work experience is not required.
