Post Doctoral Researcher

Project
PREP0002349
Overview

Radiocarbon Measurements by Cavity Ring-Down Spectroscopy

Work will include handling, preparation and preconcentration of gas-phase samples, performing ultrasensitive CRDS, and interpreting data to infer the origins and/or composition of the carbon source material. Success will require the design and assembly of a CO 2 preconcentration system, and the control and automation of laser-based instrumentation. Further work will include the use of metrology tools like optical frequency combs and NIST pressure and temperature standards to establish traceability.

Qualifications

PhD in Chemistry, Physics, or a related field.
Must have completed their PhD within the last 5 years.
Demonstrated experience performing isotopic analysis of greenhouse gases and/or air samples.
Interest in field sampling and measurements of greenhouse gases like carbon dioxide (CO 2 ).
Familiarity with high-resolution molecular spectroscopy and/or laser absorption spectroscopy.
Ability to control/automate scientific test equipment, gas handling systems, and laser instruments.
Ability to program in Matlab, LabVIEW, Python or similar software.
Strong oral and written communication skills.

Research Proposal
