RESEARCH

I study how galaxies formed and evolved when the Universe was only a fraction of its present age. I am particularly interested in where and when the Universe made its stars and the complex chemical elements that we are all made of.


In my work I use space- and ground- based observatories.  From the ground, the CFHT, Subaru, and Gemini observatories in Hawaii and Chile are key. From space it’s Hubble and Spitzer, and very soon now the James Webb Space Telescope (JWST) where as a long-standing core member of its NIRISS instrument science team I will be using a truly massive 200 hours of Guaranteed Time Observations starting in 2021.

TEACHING

I regularly teach graduate and undergraduate courses, including cosmology, galaxy formation and evolution, observational astronomy, and 2nd-year physics of periodic systems.


In Academic Year 2019/20 I will be on research leave, but I will be back in the classroom come September 2020, teaching graduate Cosmology and 3rd-year Statistical Mechanics!

POSTDOC POSITIONS OPEN:

We have 2 post-doc positions open this Fall - check on the AAS Job Register here and here. One position will focus on imaging with JWST and large-area ground based surveys, the other on spatially-resolved IR spectroscopy with GIRMOS and JWST. Deadline: January 6.


The positions will be joining our growing research team and will be located at Saint Mary’s University in Halifax, a major centre on the Atlantic coast of Canada (click here).


Additionally, a third position, in support of the JWST GTO program and will be located in beautiful Victoria, BC.  Please look for the job ad on the AAS job register here. Deadline: December 17.


We also welcome externally-funded Fellowships (NSERC, CITA, Banting, JSPS, Marie Curie) in our group, so please consider applying for these (deadlines vary).

NEWS
2020 January 22: 
Thibaud’s luminosity functions paper goes on arXiv (click here). This work presents the best, most precise to date measurement of the rest-frame UV and U-band luminosity functions and their evolution from z~3 to z~0. In it we use 4 million (!!) galaxies to measure both the bright and faint ends of the LF simultaneously. 
    In this work we use our CLAUDS + HSC data to show that the shape of the UV luminosity function is remarkably stable, and that the evolution of the cosmic UV luminosity density (which we also measure) is driven almost entirely by the change in M*, the characteristic brightness of the galaxy population out to at least z~1. 

2020 January 13-14: 
Starting the new decade off by giving colloquia about the CLAUDS project at UBC (Monday) and NRC-Herzberg (Tuesday). Great thanks for warm welcomes and lively discussions at both institutes!
