My Curriculum Vitae  and Publication List. Check out SAGA Survey Stage II results!

I am a NASA Einstein Fellow of the Hubble Fellowship Program, currently affiliated with the Department of Physics and Astronomy at Rutgers, The State University of New JerseyNew Brunswick.

My research answers key questions about the nature of dark matter, galaxy formation physics, and the uniqueness of our own Milky Way by studying the connection between visible galaxies and their nests, the invisible dark matter halos.

I participate in many science collaborations: I have been co-piloting the SAGA Survey, an ongoing spectroscopic galaxy survey aiming to characterize Satellites Around Galactic Analogs. I also serve as a Dark Matter Working Group co-convener, a Data Access Team co-lead, and a Collaboration Council member in the Rubin Observatory LSST Dark Energy Science Collaboration (DESC); I was credited the Builder Status by the DESC in 2019.

I received my Ph.D. in Physics from Stanford University in 2016. At Stanford, I was a Weiland Family Stanford Graduate Fellow and a Paul Giddings KIPAC Fellow. My thesis advisor was Risa Wechsler.

From 2016 to 2019, I was a Samuel P. Langley PITT PACC Postdoctoral Fellow in the Department of Physics and Astronomy at the University of Pittsburgh.

I was born and raised in Taipei, Taiwan. I received my B.S. in Physics from National Taiwan University in 2009.

I care about inclusion and equity, both in academia and more broadly. I am the current maintainer of the Astronomy and Astrophysics Outlist.

I am an avid programmer. Check out some software tools that I've developed, and also my  GitHub profile.

My name

My name is 茅耀元 in Traditional Chinese; the first character is my last name Mao.

At work I usually go by just "Yao", and use they or he as my pronouns.

How to pronounce my name?

  • Each character of my name is monosyllabic.
  • Yao starts as in yard and ends as in cow, with the falling (4th) tone.
  • Yuan starts with the ü sound, like über in German or lune in French (similar to few in English but with rounded lips), and it ends as in Ben, with the rising (2nd) tone.
  • Mao has the same vowels as in Yao, but with the rising (2nd) tone.
  • Listen to the pronunciation of my name with Google Translate.

How to style my name in writing?

  • In writing, "Yao‑Yuan" as a whole is my first name, with the hyphen indicating two syllables. Both Y's should always be capitalized.
  • When hyphen is not allowed (but why?), my first name can be written as "Yao Yuan". However, "Yuan" should not be considered as a middle name, nor should it be combined with "Yao" into a single word.
  • When abbreviated, my name should appear as "Y.‑Y. Mao".
  • In casual situations where only first names are being used, it is appropriate to use just "Yao" like in verbal communications.
  • These styling rules are for myself. They are not general rules and do not apply to everyone who use romanized Chinese names.
