Scientist - Aerosol Chemistry

Job ID 2072 Date posted 02/19/2020

Brookhaven National Laboratory is a multipurpose research institution funded primarily by the U.S. Department of Energy’s Office of Science. Located on the center of Long Island, New York, Brookhaven Lab brings world-class facilities and expertise to the most exciting and important questions in basic and applied science—from the birth of our universe to the sustainable energy technology of tomorrow. We operate cutting-edge large-scale facilities for studies in physics, chemistry, biology, medicine, applied science, and a wide range of advanced technologies. The Laboratory's almost 3,000 scientists, engineers, and support staff are joined each year by more than 4,000 visiting researchers from around the world. Our award-winning history, including seven Nobel Prizes, stretches back to 1947, and we continue to unravel mysteries from the nanoscale to the cosmic scale, and everything in between. Brookhaven is operated and managed by Brookhaven Science Associates, which was founded by the Research Foundation for the State University of New York on behalf of Stony Brook University, and Battelle, a nonprofit applied science and technology organization.

The Environmental & Climate Sciences Department focuses on a wide range of theoretical, experimental, and field studies in support of the U.S. Department of Energy's climate research agenda. Within the Department, the Atmospheric Radiation Measurement (ARM) Research Facility is an observation-based program created to measure aerosols, clouds, precipitation, radiation, dynamics, and thermodynamics, with the ultimate goal of reducing the uncertainty in global and regional climate models. These observations are supported by various measurement platforms and instrument suites designed to conduct in situ observations of aerosols and related trace gases.

The Environmental and Climate Sciences Department has an exciting opportunity for a scientist with in depth experience with aerosol mass spectrometry (AMS) to perform research on chemical aspects of aerosols related to climate and to be responsible for the operation, maintenance, and deployment of the DOE Atmospheric Radiation Measurement (ARM) User Facility’s Aerosol Chemical Speciation Monitors (ACSM). The job has two main roles, of equal weight. In the first role, the scientist will design and carry out independent research on aerosol chemistry and/or microphysics within a highly collaborative environment on topics that align with our Science Focus Area (SFA) ( for the US DOE Atmospheric System Research (ASR) program. In this capacity, the scientist will be expected to publish, present results at national and international scientific conferences, develop future directions for his/her research program, and participate in and contribute to the development and growth of the department. In the second role, the scientist will be responsible for multiple ACSMs ( In this capacity, the scientist must be proficient in deployment, operation, calibration, maintenance, and repair of the ACSM (see Appendices B and C of This role requires domestic and foreign travel (up to two months per year) in support of ARM-sponsored field programs; documentation, analysis, and quality assessment/quality control (QA/QC) of ACSM data; support and interaction with ARM personnel and other stakeholders with regard to the ACSM data; identification and implementation of instrumental and procedural improvements to ARM measurement systems; and the ability to work well in a diverse team across cultures, language skills, and experiences.

This position is on the Scientific Tenure Track.  The appointment level for the selected applicant will be commensurate with experience and scientific accomplishments.

Essential Duties and Responsibilities:

For the SFA role:

  • Conduct independent research of high scientific value in aerosol chemistry and/or microphysics relevant to climate, suitable for publication in leading journals; this may involve off-site work for field testing and campaigns
  • Publish scientific research in peer-reviewed journals
  • Present at national and international conferences
  • Actively participate in and contribute to program development and other aspects of the department
  • As needed, mentor students and/or postdocs, organize seminars, and represent the department and/or laboratory in work groups and committees

For the ACSM role:

  • Support ongoing field operations by providing guidance to onsite operators, specifying and updating configurations and sampling procedures, and visit field sites as necessary for installation, calibration, and maintenance of instruments. This will include both domestic and foreign travel for up to two months per year.
  • Perform field work in remote locations, including polar and tropical climate zones. Work involves moderate lifting and strenuous activities.
  • Use scientific expertise to support instrument operation by adjusting measurements based on local conditions and scientific objectives, solving measurement problems, and working with vendors to improve performance. Fundamental knowledge of measurement principles is essential.
  • Monitor data quality using scientific background; apply judgements, devise algorithmic tests, and perform QA/QC. Work with ARM Data Quality Office to develop automated checks and improved ingest and processing of data.
Initial appointment is for 2-years with expected renewal subject to continued funding and performance.

Required Knowledge, Skills and Abilities:

  • Ph.D. in the atmospheric sciences, chemistry, physics, or a related field;
  • Knowledgable in atmospheric chemisty;
  • Ability to pursue independent research;
  • Strong publication record in peer-reviewed journals;
  • Oral and written communication skills; 
  • Experience with aerosol mass spectrometry and fundamental knowledge of the measurement principles, including instrument maintenance, troubleshooting and repair, and adjusting instrument operation based on local environmental conditions;
  • Ability to travel (domestic and foreign - up to two months per year) in support of ARM-sponsored field programs; and,
  • Ability to work well in a diverse team across cultures, language skills, and experiences.

Preferred Knowledge, Skills, and Abilities:

  • Completed postdoc.
  • Experience with data analysis programs for AMS data processing and QA/QC.
  • Experience in operating Scanning Mobility Particle Sizer (SMPS) and Condensation Particle Counter (CPC).
  • Proficiency in basic aerosol instrumentation installation, operation, maintenance, and repair.
  • Experience working on field campaigns, including measurement planning, running and troubleshooting instruments in the field, and verifying/documenting data quality.

Environment, Safety & Health, and other information:

  • Ability to work in tight spaces
  • Routinely lift more than 30 pounds
