[Met-jobs] Post Doc Gas-particle partitioning in CU Boulder

From Gavin Phillips <>

Date Wed, 5 Oct 2016 15:16:05 +0000

Postdoctoral Position on Lab Gas-Particle Partitioning using ToF-CIMS
A postdoctoral position is available in the Jimenez Group in CIRES and the 
Dept. of Chemistry at the University of Colorado-Boulder 
(, collaboratively with the Ziemann group 
([ The successful candidate 
will investigate gas-particle partitioning of organic species in the 
laboratory, including how the dynamics and equilibria are affected by particle 
composition and phase state, molecular identity, humidity, temperature, OA, and 
other factors. A large suite of start-of-the-art instrumentation is available 
for the project, within two highly dynamic research groups. The key tool will 
be a real-time High-Resolution Chemical Ionization Mass Spectrometer (CIMS) 
including a FIGAERO and other inlets, I-, acetate, and NO3- sources, and a new 
Ion Mobility Spectrometer-CIMS. Participation in field studies and other 
ongoing projects is also possible. The position will involve extensive use of 
the new CU Atmospheric Chamber Facility ([, and 
also some computer modeling of partitioning equilibrium and kinetics.
Background information about the research group, techniques, and previous 
publications and projects is available at the Jimenez Group Web Page 
( Boulder is a great place to live (see, and it also houses the greatest concentration of 
atmospheric scientists in the world, thanks to the combined strengths of CU 
( and the NOAA 
( and NCAR ( National 
A Ph.D. in chemistry, atmospheric sciences, environmental engineering, or a 
related discipline is required. Skills in the operation and data interpretation 
for advanced chemical instrumentation, ideally CIMS, are important. Experience 
with mass spectrometry, vacuum technology, aerosol instrumentation, as well as 
computer programming and/or complex data analysis (especially Igor Pro) are 
highly desirable. Experience with laboratory or field studies of atmospheric 
chemistry is also desirable. Independence, drive and collaboration will be 
encouraged in order to develop the candidate's career.
To apply, please submit an application via this CU Careers Link 
(, with a cover 
letter describing your research interests, a CV, date of availability, 2-3 
first-author journal papers in PDF, and a list of 4-5 references who are very 
familiar with your research work. The initial appointment will be for one year 
(potentially starting before the end of 2016, depending on candidate 
availability), with the expectation of annual renewal for two additional years 
upon satisfactory performance. The University of Colorado is an equal 
opportunity employer.
Note that another postdoc position on Indoor Air Chemistry measurements w/ 
ToF-CIMS is expected to be available in early 2017.
