Open Positions

Staff Scientist Position

A Staff Scientist position in experimental atmospheric chemistry is available starting in Dec. 2009. This position will be 50/50 hard and soft money for at least 3 years. It will be centered in the Jimenez group but will likely be shared with other atmospheric chemistry groups within CIRES & Chemistry, such as the Volkamer, Tolbert, and Vaida groups. The Staff Scientist will help train and work with students and postdocs, and co-supervise laboratory and field experiments and data analysis and modeling studies on atmospheric chemistry.

The ideal candidate will have:

• A Ph.D. in Chemistry, Atmospheric Sciences, or a related discipline.
• Postdoctoral experience
• Ability to make a commitment of 3-5 years to this position
• Interest in working with students and postdocs and helping train them on lab techniques, see e.g. this list of lab skills
• Ability to travel to field studies to assist students & postdocs, especially during setup phase and in case of problems (~4-6 weeks total travel time per year on average)
• Willingness to participate on aircraft-based field studies
• Experience with advanced instrumentation and data interpretation, such as mass spectrometers, optical spectroscopy, vacuum technology etc.
• Desire and ability to communicate and work with multiple students and postdocs
• Experience with computer programming and data analysis, especially Igor Pro, but otherwise Matlab, Fortran, IDL etc.
• Experience with data acquisition programming with Labview (or similar software packages)
• Interest on having his/her own research projects, presenting results at conferences, and publishing some first-author papers
• Interest on participating on (and eventually potentially leading) proposal-writing

The initial appointment will be for 1 year but the expectation is of renewal for 3-5 years upon satisfactory performance. Please email jose.jimenez@colorado.edu if you are interested in this position, attaching a cover letter, your CV, 2-3 first author publications, and 4 references. The University of Colorado is an Equal Opportunity Employer.

Postdoctoral Position in Aerosol Mass Spectrometry

A postdoctoral position is available in the Jimenez Research Group in CIRES and the Dept. of Chemistry and Biochemistry at the University of Colorado-Boulder. This position focuses on field studies of organic aerosol sources and processing using high-resolution aerosol mass spectrometry (HR-ToF-AMS) and thermal desorption aerosol GC-MS (TAG) as part of the CalNex-LA-2010 and BEACHON-SRM-2011 field studies. Both field studies will provide excellent research opportunities and complementary data from many advanced instruments. Information on these studies can be found at:

• CalNex-LA

• BEACHON

A Ph.D. in chemistry, atmospheric sciences, environmental engineering, or a related discipline is required. Experience in experimental research is needed. Experience with instrument design and construction, advanced instrumentation use, computer programming, and/or complex data analysis is highly desirable. Experience with mass spectrometry, vacuum technology, aerosol instrumentation, Igor Pro or another data analysis package, Labview, or field studies are also desirable. Ability to travel to field studies, to work in a team with members of our group and multiple collaborators, and to lead the writing of papers for peer-reviewed journals is essential. Background information about the research group, techniques, and previous publications and projects is available at:

• Jimenez Group Page

Four papers that describe the techniques and scientific problems that our group focuses on can be downloaded from:

• Aiken et al., ACP 2009
• de Gouw and Jimenez, ES&T 2009
• Canagaratna et al., Mass Spec. Rev. 2007
• Hallquist et al., ACP 2009

and many additional publications can be downloaded from our group publications page:

• Group Publications Page

To apply, please send an email describing your research interests, a CV, date of availability, 2-3 first-author journal paper reprints in PDF, and a list of 4 references to Prof. Jose L. Jimenez (jose.jimenez@colorado.edu). The initial appointment will be for one year starting around Jan. 2010, with the expectation of annual renewal for two additional years upon satisfactory performance. Later start dates are also possible. The University of Colorado is an equal opportunity employer.
