Job Summary

Profs. Julio Sepúlveda and Tom Marchitto are seeking a full-time laboratory manager to oversee the Organic Geochemistry and Trace Metal Labs in the Institute of Arctic and Alpine Research (INSTAAR) and the Department of Geological Sciences at the University of Colorado Boulder. Both labs are housed in the Sustainability, Energy, and Environment Laboratory (SEEL) building, a thriving hub of Earth scientists, biologists, ecologists, and environmental engineers. The starting date is flexible, although Fall 2022 is preferred, and the appointment split will be 60% with PI Sepúlveda and 40% with PI Marchitto. Review of applications will begin in mid-September and will be accepted until the position is filled.

We are looking for a highly motivated individual with excellent communication and organizational skills to oversee instrumentation in gas and liquid chromatography–mass spectrometry (GC-QQQ-MS and HPLC-Orbitrap MS), and magnetic sector inductively coupled plasma mass spectrometry (ICP-MS). Our research groups investigate organic and inorganic chemical signatures in both modern and ancient sedimentary systems to address key questions in oceanography, biogeochemistry, paleoceanography and paleoclimatology, and geobiology. The initial appointment will be for two years with the possibility of renewal pending evaluation.

The University of Colorado Boulder is committed to building a culturally diverse community of faculty, staff, and students dedicated to contributing to an inclusive campus environment. We are an Equal Opportunity employer, including veterans and individuals with disabilities.

Who We Are

Our traditional focus has been on alpine, Arctic, and Antarctic regions, where effects of global change are especially pronounced. In recent decades, our research has broadened to include environmental challenges that span local, regional, and global scales. INSTAAR’s research activities integrate field studies, state-of-the-art laboratory experiments, sample analysis, and numerical and laboratory modeling. Our field sites are located across all seven continents and the world's oceans.

Our expertise across disciplines helps us generate influential science that can inform public and policy decisions and move us toward a more sustainable society. INSTAAR's national and international research leadership is augmented by exceptional strength in graduate education and bringing undergraduates into the research process.

INSTAAR is committed to building an inclusive, actively antiracist institute where all people from groups underrepresented in science and academia are welcome, safe, and supported. We welcome applications from individuals from diverse backgrounds and with a commitment to support INSTAAR’s mission. See the links below for more information on our JEDI mission and work:
