Job description

Faculty of Arts and Science
University of Toronto


Area of Research:

Measurements of atmospheric composition are crucial for assessing the changes occurring in Earth's atmosphere due to human activity. Observations made from high-altitude balloon platforms provide insight
into the distribution of these trace gases with altitude as well as concentration. The Canadian Atmospheric Laser Absorption Spectrometer Experiment Test-bed (CALASET) project is developing a new measurement
capability for Canada by utilizing balloon-borne laser spectroscopy.

Description of duties:

The successful applicant will be part of a team developing a new payload for in situ measurements of the atmosphere from a high-altitude balloon platform.  This payload will be used to measure concentration profiles
of trace gases.  Working with the CALASET team, the PDF will participate in the development of an infrared laser absorption spectrometer including contributions to the design, construction, testing and deployment phases.  The position is based in Toronto, Canada and will be jointly supervised by Prof. Kaley Walker and Prof. Wolfgang Jaeger (Department of Chemistry, University of Alberta). This position will involve travel and extended field work.  Also, the PDF will spend part of their time working in Prof. Jaeger’s group in Edmonton, Canada. The period and timing of these visits is to be negotiated between the supervisors and successful applicant.

Salary: $45,000 per year.

Required qualifications:

A Ph.D. degree in Physics, Chemistry or a relevant field is required. We seek a candidate with expertise in construction and/or operation of field or laboratory instrumentation and programming experience (preferably with Python and Linux). Experience with laser spectroscopy (including diode laser or QCL technologies), scientific balloon measurements and/or atmospheric monitoring would be very advantageous.

Application instructions

All individuals interested in this position must submit a CV, the names and contact information for at least two referees, and a statement summarizing their experience and how it is relevant to this position to Prof. Kaley Walker (via email at) by the closing date.

Closing date: Consideration of applications will begin on 19 May 2017.
However, applications will be accepted until 1 July 2017 or until the position is filled.
