Post-Doctoral Associate in Atmospheric Chemistry Prof. Hannah Kenagy

Position Summary / Primary Purpose of Position:
The Kenagy Lab (Department of Chemistry;(Use the "Apply for this Job" box below).) at the University of Minnesota isseeking a Postdoctoral Researcher to join an upcoming ground-based field campaign focused on particle formation chemistry in agricultural regions. While agricultural emissions represent agrowing driver of air quality as urban emissions decline, theirunderlying atmospheric chemistry remains understudied–a criticalgap this project aims to fill. The successful candidate will leadthe deployment of aerosol instrumentation during this project andwill bring a strong foundation in atmospheric or environmentalchemistry, chemical analysis, data processing and analysis, and dissemination.

This position is available starting in January 2027.The work schedule is typically Monday-Friday, with some weekend work during field deployments (planned for 6 weeks in summer 2027and 4 weeks in summer 2028). Outside of deployment periods, thework schedule has increased flexibility to balance the field work demands.

30% Instrument Calibration, Operation, and Maintenance:
This position will lead the operation of an aerosol chemical speciationmonitor (ACSM) and scanning mobility particle sizer (SMPS) forparticle composition and size analysis, respectively. They willwork collaboratively with a UMN graduate student who will lead the deployment of a chemical ionization time-of-flight massspectrometer (CI-ToF-MS) for gas analysis, as well as with a teamof collaborators from Purdue University who will measure trace gasfluxes.

30% Data Analysis:
This position will lead the data processing and data analysis for the ACSM and SMPS and will assist with the processing and analysis of CI-ToF-MS data.

10% Mentorship:

This position will work closely with a graduate student in preparing for and completing the deployments.

10% Outreach:
This position will contribute to a collaboration with a 4H Youth Development specialist to develop a hands-on workshop where high school students explore agriculture and air quality throughlow-cost sensor building, field measurements, and data analysis.

20% Research Documentation, Dissemination, and Publication:
Workwith the PI to plan and draft extramural research proposals and manuscripts reporting study results. Contribute to the preparation of presentations and other research communications.

• PhD in chemistry, atmospheric science, environmental science,engineering, or a closely related field.
• Hands-on experience with instrument calibration and operation.
• Data analysis experience.
• Proficiency in statistical data analysis and coding (e.g.,Python, R).
• Strong organizational skills with experience in laboratory operations.
• Effective written and verbal communication skills.
• Familiarity with standard laboratory safety practices.

• A strong publication record demonstrating independent researchcontributions.
• Experience with mass spectrometry.
• Experience preparing research documentation such as manuscripts,grant applications, or regulatory submissions.
• A willingness to learn and expand skillset and research interests.
• Previous experience mentoring or supervising trainees,particularly undergraduate students.
