SENIOR RESEARCH ASSOCIATE - Liquid Surface/Interface Science
Center for Advanced Radiation Sours (CARS) at the University of Chicago

The Center for Advanced Radiation Sources (CARS) at the University of Chicago houses three national synchrotron x‐ray user research facilities, GSECARS, BioCARS, and ChemMatCARS, at Sector 13, 14 and 15, the Advanced Photon Source (APS), Argonne National Laboratory (ANL).

CARS invites applications for a Senior Research Associate (SRA) position in the area of liquid surface/interface science to join ChemMatCARS, which operates a world‐class synchrotron x‐ray liquid surface scattering facility available for scientists world‐wide. Synchrotron x‐ray liquid surface scattering is the most powerful probe of molecular and mesoscale structure at liquid interfaces and is indispensable for understanding the fundamental science of soft interfaces, as well as model systems of many natural and technological systems. The successful candidate will be expected to originate and engage in collaborative efforts in x‐ray studies of liquid surfaces with ChemMatCARS users and staff, lead the user program on the liquid surface/interface science, as well as lead R&D efforts to expand capabilities of synchrotron beamlines in the area of liquid surface and interface science. Scientific areas of interest include, but are not limited to, ionic liquid interfaces, ferroelectric assemblies, tunable nanoparticle arrays, nanoparticle toxicity, chemistry of life processes at the liquid interfaces, and separation of metal ions by solvent extraction.

The position requires a Ph.D. in Chemistry or Physics in the study of liquid surface/interface phenomena with synchrotron x‐ray surface scattering techniques, a research record in liquid surface/interface x‐ray scattering science, and a minimum of 8 years of relevant experience with 3 years in running user science program at a synchrotron x‐ray liquid surface scattering
facility. Experience in advanced synchrotron x‐ray liquid surface/interface scattering techniques, such as GISAXS, XFNTR and high energy PDF, is highly desirable. Capability of developing liquid surface x‐ray scattering techniques, strong computer skills, as well as a demonstrated ability to use these to write data acquisition, data analysis, and instrumentation control software, are also preferred. Expertise in the full range of synchrotron x‐ray techniques, including the use of high energy x‐rays (20 keV and above), for studying liquid surfaces and interfaces is especially beneficial. Moreover, the successful candidate will have the opportunity to serve in the role of Principal Investigator, writing proposals to federal and non‐federal agencies to support such research and development.

The successful applicant must be able to satisfy the requirements for access to ANL. Interested candidates must apply through the University’s Academic Jobs website at (Posting number: 03685)

A CV including a list of publications, names and contact information for three references, and a statement describing past and current research accomplishments must be uploaded to be considered as an application. Review of complete applications will begin April 26 and will continue until the position is filled.

Canadian Light Source Inc.

Canadian Light Source Inc. (CLSI) is Canada’s national synchrotron research facility located on the campus of the University of Saskatchewan in Saskatoon, helping to facilitate scientific research aimed at finding Canadian solutions for global challenges in agriculture, health, advanced materials and the environment.

In support of Canadian-based researchers, CLSI and Argonne National Laboratory have entered into a partnership to operate the Spectroscopy group (SPC) of the X-ray Science Division (XSD) Facility at the Advanced Photon Source (APS) in Argonne, Illinois. The SPC group operates and maintains the sector 20 and 9-bend magnet (BM) beamlines.

CLSI is currently recruiting an Associate Scientist (equivalent to an Assistant Physicist position at the APS) to work as a member of the Spectroscopy (SPC) group to support Canadian researchers. The incumbent will be based at the APS, with an employment contract facilitated through a Research Service Agreement between the Illinois Institute of Technology and  CLSI.

Responsibilities: Reporting to the CLS@APS Staff Scientist, the Associate Scientist will be a positive representative of the CLS, supporting the general user program at sector 20 and 9-bend magnet (BM) beamlines.  This includes providing Canadian users with proper training, preparing the beamline for different experiments, and assisting the users during their measurements. As a member of the SPC group, the Associate Scientist will be expected to perform general beamline maintenance and scheduled beamline performance tests, as well as prepare documentation and protocols for sector 20 and 9-BM operation. The incumbent must have a strong interest in conducting research, either independently or collaboratively, utilizing sector 20 and 9-BM beamlines. Working flexible hours, including evenings and weekends, is a requirement of the position. Travel to the CLS may be required on occasion.

Requirements: Applicants should possess considerable experience in the application of x-ray spectroscopy to problems in surface science, materials, catalysis, chemistry, life sciences or environmental science.  A good knowledge of general experimental practices currently employed at x-ray synchrotron radiation facilities is important.  Skill in working with diverse research groups, potentially outside the position’s primary field of expertise, to understand abstract concepts and aid in interpreting results within experimental and theoretical frameworks is an asset.  The successful candidate has earned a Ph.D. degree in a relevant discipline and should have a strong research background with a continuing interest in personal research. This position requires an individual who is willing to relocate to Argonne, Illinois.

Remuneration: Compensation will be commensurate with qualifications and experience, with a salary range of $56,000 to $75,000 USD per annum. Benefits include supplemental health & dental, life insurance, and 4 weeks annual vacation as part of a competitive compensation package.

Interested individuals should submit a resume along with a list of three references, in confidence to Please quote Job No. 911 in the subject line of the email. Applications will be considered as of February 15, 2018 and will continue until the position is filled. While all applicants are thanked for their interest, only short-listed candidates will be contacted.   Visit our website:
