I am an Astronomer/(Sub)millimeter Instrument Scientist at the European Southern Observatory (ESO), overseeing portions of ALMA development. Scientifically, I work primarily on observations of galaxy clusters through the Sunyaev-Zel'dovich (SZ) effect. Please see here for the arXiv.org version of the SZ review, or here for the fully published version.

News:

The AtLAST Design Study is underway! See atlast-telescope.org, for the latest updates and news.
Press release (also image below) on the detection of hot gas in the Spiderweb Protocluster at z~2.16.
Press release on the MUSTANG-2 observations of the cavities in MS0735.6+7421
A bit less recently, but ACA+ALMA Bullet SZ analysis was a highlight in A&A and on the ALMA Science Portal!

Here are some of the instruments and projects I work on or have worked on:

ACT: The Atacama Cosmology Telescope was a 6-meter CMB (and SZ) survey telescope, decommissioned in 2022.
ALMA: a 66-element mm/submm-wave interferometer and total power array in the Atacama desert in northern Chile. I'm working (along with many others) to improve the mapping speed, to bring new bands online, and to realise the ALMA 2030 Development Roadmap. See the Wideband Sensitivity Upgrade memo
AtLAST: The Atacama Large Aperature Submillimeter Telescope, a community-driven effort to realise a 50-meter widefield, high throughput submm telescope in the Atacama desert. Currently no large (>12-meter) submm/mm single-dish facilities exist in the southern hemisphere, and no facilities >15-meter anywhere can access frequencies >400 GHz. AtLAST would significantly advance submm/mm science, improving upon ALMA's mapping speed by >5 orders of magnitude.
CMB-S4
MUSTANG2: a 90 GHz, 9" SZE imaging camera on the 100-meter Green Bank Telescope.
Simons Observatory

And finally, my Orcid and Google Scholar pages can be found here:
