Application Deadline: 7/5/2024 3:00:00 PM Eastern Time Zone

Reference Code: EPA-ORD-CCTE-CCED-2024-03

Research Project: Non-targeted analysis (NTA) has been increasingly used in recent years to elucidate structures of novel compounds of emerging concern, however, the majority of studies use liquid chromatography. Gas chromatography (GC) has the potential to be equally useful and compliment chemical space coverage but methodologies for GC data collection and processing need to be further developed, tested, and applied in order to be widely adopted and used in decision making.

The goal of the research project is to develop GC-NTA techniques to identify chemicals of interest in environmental samples.

Under the guidance of a mentor, the research activities will include, but not limited to:

• Exploring the usefulness of combining data from various ionization techniques (e.g., electron impact, chemical ionization).
• Exploring and mastering software features (e.g., Compound Discoverer, MSDial, etc.).
• Writing QA/QC procedures and documents, and writing programming code (R, python, or other) for processing data output.

Applications of GC-NTA will include identification of novel per- and polyfluorinated alkyl substances (PFAS) in samples originating near manufacturing facilities and products of incomplete combustion formed from household items during a fire.

Learning Objectives: The research participant will be part of a multidisciplinary team of experts who are identifying chemicals to which humans are exposed. The research participant will be expected to actively participate in internal and external research groups such as the EPA NTA group, a GC-Orbitrap users group, etc. An emphasis will be placed on publishing in peer-reviewed journals with the aim of preparing the research participant for a successful career in science.

Mentor(s): The mentor for this opportunity is Seth Newton (Newton.Seth@epa.gov). If you have questions about the nature of the research please contact the mentor.

Anticipated Appointment Start Date: May 15, 2024. All start dates are flexible and vary depending on numerous factors. Click here for detailed information about start dates.

Appointment Length: The appointment will initially be for one year and may be renewed upon EPA recommendation and subject to availability of funding.

Level of Participation: The appointment is full-time.

Participant Stipend: The participant will receive a monthly stipend commensurate with educational level and experience. Click here for detailed information about full-time stipends.

Open position in the Department of Environmental Science

The Department of Environmental Science is one of the largest departments in the Faculty of Science. The department is divided into four units with more than 190 researchers, teachers, doctoral students and technical/administrative staff from over 30 countries. Research and teaching focuses on chemical contaminants, atmospheric science, biogeochemistry, and (eco)toxicology. As an employee at the Department of Environmental Science you will be part of a dynamic environment with a strong international profile.

Research in the Contaminant Chemistry Unit focuses on the occurrence and behavior of pollutants in the environment and in the technosphere. Areas of particular focus include the discovery of new contaminants, understanding the physical, chemical, and biological pathways that contaminants follow, and the development of novel tools and techniques for sampling and analysis. We strive to synthesize our scientific understanding about the sources, transport, transformation, bioaccumulation and pharmacokinetics of environmental contaminants into mathematical models that inspire new scientific hypotheses, and support environmental decision-making.

The 21st century has seen exponential growth in both the volume and diversity of organic chemicals and plastic produced globally. As emissions increase, our ability to identify and
monitor these so-called “novel entities” in the environment using conventional tools becomes increasingly difficult. To address this problem, next-generation analytical and data science tools are urgently needed. For example, state-of-the- art mass spectrometers can now measure thousands of known and unknown chemicals simultaneously, providing unprecedented insight into the extent of chemical contamination of the global environment. At the same time, data science tools such as machine learning (and more generally, artificial intelligence) have opened up new possibilities for predicting, identifying, and quantifying problematic chemicals, and for improving our understanding of their environmental fate, behavior and effects. These emerging data science tools are increasingly in demand in a range of jobs in private industry and government, highlighting the need for their inclusion in our Department’s Educational programme.

Considering the rapid growth within environmental chemistry and data science, we believe it is strategically important to recruit an early career Environmental Chemist with expertise in emerging Data Science tools to support our core missions in research, teaching and outreach. The successful applicant will be encouraged to exploit our state-of-the-art interdepartmental Mass Spectrometry lab (MassSLab), as well as existing networks such as the Centre for Circular and Sustainable Systems (SUCCeSS), and Science for Life Laboratory (SciLifeLab), while building new connections which contribute to enhancing the Department’s reputation as a global leader in Environmental Science research and education.

Familiarity with QTOF platforms, Agilent software, statistical analyses of large data sets, computational and statistical data analysis, machine learning, and innovative sample processing are especially valued. The candidate will support exploratory research, method development, several ongoing projects, and contribute to research proposals. The candidate will help lead our research group and projects while working with a broad collaborative team of environmental researchers, including undergraduate and graduate students, post-doctoral scientists, research scientists, technicians, and academic faculty.
