Dongwoo Chung

I'm a PhD candidate in Physics at Stanford, working on observational extragalactic astrophysics and cosmology.

I will be migrating and updating this site through autumn 2020 as I obtain my PhD and begin a term position as a CITA-Dunlap postdoctoral fellow at the University of Toronto. Watch this space!

Research activities

Here is an ADS library of articles that I've written or been involved in otherwise in some form.

My main research interest is in tracing the clustering of high-redshift galaxies through line-intensity mapping. Under the supervision of Sarah Church, I have worked on various aspects of the Carbon monOxide Mapping Array Pathfinder (COMAP), which aims to measure the CO(1-0) line-intensity power spectrum at redshift 3.

Most of my publications look at various questions about how to model the target signal for COMAP, with topics such as

Beyond modelling, I have also been involved in commissioning of the COMAP instrument, with tasks including

I have also written signal and sensitivity forecasts for the [C ii] line at high redshift as part of work done for the CCAT-prime science working group, and was involved in the final stages of lab integration of the Argus receiver on the Green Bank Telescope as part of the instrument team.

Teaching and service

I have worked as a teaching assistant in three different introductory physics courses at Stanford. Each time, a key goal has been to employ active learning techniques to have students reflect on their problem-solving process and thus gain understanding in ways that they could not with rote methods. I've been lucky enough to work under the supervision of physics education faculty and staff at Stanford who have strong interests in improving undergraduate courses through better teaching methods.

I mentored one undergraduate summer student in 2018, who worked on COMAP gain calibration as well as calibrator assembly and testing.


Until recently, I served on the Stanford Physics Equity and Inclusion Committee, as one of several graduate student representatives. As my first project, I led a redesign of the E&I committee's website to make more information more presentable to those interested. Working with the other student representatives, I also helped start a series of meetings with graduate students beyond the committee to identify action items in line with the E&I committee's strategic plan, with topics ranging from graduate admissions and first-year advising to health care subsidies and department climate.

I have also taken part in numerous education and public outreach events representing the Kavli Institute for Particle Astrophysics and Cosmology (KIPAC), from middle school science fairs to APS expos.

Miscellaneous history, professional and otherwise

I obtained an AB in Physics (high honours) as part of Princeton's Class of 2014. Most of my independent work was done with the Gravity Group. I did one summer's work on ACTPol bias electronics and one summer plus a junior paper's worth of work on MuSE bolometer characterisation. I completed an experimental senior thesis on microwave SQUID multiplexing, supervised by Lyman Page.

Beyond research and departmental service, I also served as webmaster for Stanford's Graduate Students in Applied Physics and Physics group, and have participated frequently in the Meeting of Astrophysics Students at Stanford (MASS) as well as the KIPAC Statistics and Machine Learning Journal Club.
