Roles and responsibilities
Research and design engineering to support radio astronomy, specifically the electromagnetic (EM) design of reflector antennas, feed antennas including arrays, and radio-frequency (RF) signal chains. Also responsible for maintaining antenna engineering development infrastructure consisting of design software (GRASP, CST), a near-field spherical antenna range (measure radiation patterns), and the Hot/Cold Test Facility (measure the sensitivity of receiving systems).
Current research and/or projects
- RF signal chain design for the DRAO Synthesis Telescope upgrade.
- Member of the Canadian Galactic Emission Mapper (CGEM) team (led by UBC), helping with optical and RF signal chain design.
- Member of the Canadian Hydrogen Observatory and Radio-transient Detector (CHORD) team (collaboration of McGill, University of Toronto, NRC, and other universities).
- Member of the Radio Telescope Modelling team (RTMod) at DRAO, working on methods to integrate EM modelling along with structural analysis and using radiometric, photogrammetric, and laser-tracking measurements for verification.
