Postdoctoral Research Associate Radiolytic Reaction Kinetics

Job ID 2863 Date posted 04/30/2022

Brookhaven National Laboratory ( delivers discovery science and transformative technology to power and secure the nation’s future. Brookhaven Lab is a multidisciplinary laboratory with seven Nobel Prize-winning discoveries, 37 R&D 100 Awards, and more than 70 years of pioneering research. The Lab is primarily supported by the U.S. Department of Energy’s (DOE) Office of Science. Brookhaven Science Associates (BSA) operates and manages the Laboratory for DOE. BSA is a partnership between Battelle and The Research Foundation for the State University of New York on behalf of Stony Brook University.

Organizational Overview

The mission of the Chemistry Division ( is to conduct basic and applied chemical research with an emphasis on new energy conversion pathways. The Electron- and Photo-Induced Processes (EPIP) Group ( is a leader in the application of both photoexcitation and ionization by short pulses of fast electrons (radiolysis) to investigate fundamental chemical problems relevant to the production and efficient use of energy, thus obtaining unique insights not attainable with other techniques. These studies may play an important role in the development of safer, more effective, and environmentally beneficial processes for the chemical conversion of solar energy and advanced nuclear fuel cycles. The EPIP group utilizes cutting-edge radiolysis tools within its Accelerator Center for Energy Research (ACER,, including the 9 MeV picosecond Laser Electron Accelerator Facility (LEAF) and a 2 MeV Van de Graaff accelerator for pulse radiolysis, and 60Co sources for continuous gamma radiolysis. A wide variety of time-resolved detection methods are available for pulse radiolysis, including transient absorption from the UV to mid-IR, as well as microwave conductivity.

Position Description

The Chemistry Division has an opening for a postdoctoral research associate in the Electron- and Photo- Induced Processes Group. The successful candidate will work on gaining a fundamental mechanistic understanding of the radiation chemistry of organic liquids, such as acetonitrile, and DMF, using pulse radiolysis, gamma radiolysis and/or laser flash photolysis. This will include the development of new solvent-class-based radical scavengers for the conversion of radiolytic solvent radicals into secondary reductants/oxidants and/or less reactive species. Another major aspect of the work will be to develop and exploit the unique time-resolved mid-IR (TRIR) detection capabilities at ACER for the structural characterization of transient intermediates involved in light harvesting charge transfer and the radiolysis of non-aqueous media that are important in energy-related applications, such as ionic liquids and alkyl carbonates. The work will be under the supervision of Dr. David Grills.

Essential Duties and Responsibilities:

  • Plan and carry out research in radiation-induced reaction kinetics and mechanisms, including pulse radiolysis experiments on ACER’s accelerator facilities.
  • Develop and apply the TRIR detection methodologies at ACER to systems relevant to solar energy conversion.
  • Manuscript preparation and presentation of results at national and international meetings.

Position Requirements

Required Knowledge, Skills, and Abilities:

  • Ph.D. in chemistry or a related field.
  • Experience with basic synthetic methods and sample preparation under inert conditions.
  • Self-motivated and able to work in a diverse, collaborative team environment.
  • Excellent verbal and written communication skills as evidenced by a publication history.

Preferred Knowledge, Skills, and Abilities:

  • Radiation chemistry (including pulse radiolysis), photochemistry or a related field.
  • Experience with time-resolved spectroscopies, such as UV/Vis transient absorption (TA) and time-resolved infrared (TRIR).
  • Kinetic modeling, thermodynamics, electron transfer.
  • Experience designing, building, and/or modifying experimental apparatus.

 Additional Information: 

BNL policy requires that after obtaining their PhD, eligible candidates for research associate appointments may not exceed a combined total of 5 years of relevant work experience as a post-doc and/or in an R&D position, excluding time associated with family planning, military service, illness or other life-changing events.

 At Brookhaven National Laboratory we believe that a comprehensive employee benefits program is an important and meaningful part of the compensation employees receive. Our benefits program includes, but is not limited to:

  • Medical, Dental, and Vision Care Plans
