Postdoctoral Position in Environmental Chemistry

We are seeking to hire a highly motivated, full-time postdoctoral fellow with a background in Environmental Chemistry/ Environmental Engineering or related field to work on the project ‘Fate and Transport of Unregulated Organic Contaminants in Biosolids – Development of a Human and Environmental Exposure Risk Framework’ funded by the U.S. EPA (additional details can be found here).

The goals of the project are to i) identify organic contaminants in biosolids from across the U.S. using liquid chromatography – high-resolution mass spectrometry (LC-HRMS) approaches, ii) assess their fate in agricultural soils, including groundwater leaching and plant uptake, and iii) evaluate the potential exposure risks using computational toxicology approaches. This exciting position, which involves conducting research from both an academic and practical perspective, provides substantial career growth opportunities.

The primary responsibilities for this position will include:

  • Planning, conducting and managing laboratory experiments to identify organic contaminants in biosolids from across the U.S. and evaluate their fate in agricultural soils and assess plant uptake
  • Planning, conducting and managing field studies to assess the fate of biosolid contaminants
  • Supervising of PhD and Master’s students
  • Supporting the Principal Investigator in the coordination of sampling efforts
  • Support the Principal Investigator in coordination of project meetings and dissemination of project outcomes
  • Preparing manuscripts for peer reviewed journals and presenting findings at conferences

Required Qualifications & Skills:

  • Ph.D. in Environmental Engineering, Environmental Chemistry or related discipline.
  • Demonstrated knowledge and expertise with the analysis and fate of organic contaminants in the environment with a demonstrated publication record in these areas.
  • Experience conducting laboratory studies to investigate the fate of organic contaminants.
  • Experience with the analysis of organic contaminants, in particular liquid chromatography – mass spectrometry (LC-MS).
  • Experience with LC – high-resolution MS (LC-HRMS) is desirable but not required.
  • Extremely strong verbal and written skills. Evidence of writing skills will be requested.
  • Strong problem-solving and organizational skills.
  • Detail oriented.

Applicants should submit an electronic version of their curriculum vitae, a 1-2 page statement of interest, and the names and contact information for 3-5 references.

Correspondence should be addressed to:

Dr. Carsten Prasse
Department of Environmental Health and Engineering
Johns Hopkins University Bloomberg School of Public Health/Whiting School of Engineering
615 North Wolfe Street Room E6636
Baltimore, MD 21205

We have positions available at the undergraduate and graduate level. Applications from prospective visiting students and researchers are also welcome.
