Pacific Northwest National Laboratory Post Doctorate RA - Analysis of measurements of SOA formed in particles and clouds in RICHLAND, Washington

Organization and Job ID

Job ID: 310646

Directorate: Earth & Biological Sciences

Division: Atmospheric Sciences & Global Change

Group: Earth System Modeling

Job Description

Pacific Northwest National Laboratory (PNNL) is seeking a highly motivated postdoctoral research associate with a strong background in atmospheric chemistry of organic aerosols who will develop and apply innovative techniques for measurement and analysis of aerosols. The candidate will also work on analysis of data collected during recent field campaigns conducted by the Atmospheric Radiation Measurement (ARM) facility, and other complementary laboratory and field measurements.

Aqueous and cloud chemistry of organic aerosols is one of the least understood aspects of aerosol-cloud interactions. Our project focuses on analyzing aqueous and cloud chemistry data from several laboratory and field measurements. The objective is to elucidate new processes based on these measurements, and build cutting-edge integrative-predictive models, which will be used to understand the role of aqueous and cloud chemistry in aerosol-cloud interactions.

The ideal candidate will have demonstrated prior knowledge in measurement, troubleshooting and analysis of aerosol chemical composition and size distribution measurements, mainly collected from Aerosol Mass Spectrometer (AMS). The candidate would be expected to make new measurements of SOA using AMS in the laboratory and also analyze measurements to understand aqueous aerosol chemistry processes observed in the laboratory and field. Working in a highly collaborative environment, the candidate will develop their own hypotheses of aqueous and cloud chemistry processes, and execute a research plan that addresses those hypotheses. The position will provide many opportunities to learn other aerosol measurement techniques including the single particle laser ablation mass spectrometer (SPLAT), and also atmospheric modelers at PNNL, and other national laboratories and Universities.

This is a full-time position anticipated to last for two years (contingent on performance), starting as soon as possible.

Please provide a single PDF file containing (1) a cover letter of 1-2 pages summarizing research interests, qualifications and experience that fit the advertised position and possible start date at PNNL if selected (2) a CV listing past employment, education and research experiences, skills, publications and contact information of three references.

Further details about the position can be obtained from Dr. ManishKumar Shrivastava (

Preferred Qualifications

  • A strong background in secondary organic aerosols

  • Familiarity with Aerosol Mass Spectrometer data and other aerosol measurements

  • Familiarity with computer languages (FORTRAN, Python, etc.), data analysis tools and techniques (such as IGOR, R, NCL, Matlab, IDL, etc.)

  • Ability to analyze a wide range of chemical and aerosol measurements

  • Track record of high-quality publications in peer-reviewed journals

  • Strong communication skills

Candidates must have received a PhD in atmospheric science or a related field.¿
