Hi! I'm I-Da Chiang (江宜達), an observational astronomer at Institute of Astronomy and Astrophysics, Academia Sinica (ASIAA) studying dust and the interstellar medium in the nearby galaxies.

Research

I am interested in the relations between dust, metal, and neutral gas in the interstellar medium (ISM), especially how these relations evolves in different physical environments. I use the spatially-resolved (kpc scales), multi-wavelength data (far-ultraviolet to radio) to trace various physical quantities in the nearby universe in order to conduct my research.

About Me

I am currently a postdoc fellow at the Institute of Astronomy and Astrophysics, Academia Sinica (ASIAA). I work with Dr. Hiroyuki Hirashita to combine the efforts of modeling and observations to attack the remaining questions about dust evolution. I joined ASIAA in 2021. I am a member of the z0MGS and PHANGS collaborations. Prior to my current position, I got my Ph.D. in astrophysics (well, officially just physics) at the Center for Astrophysics and Space Sciences (CASS), University of California San Diego (UCSD). During my PhD, I was a member of Prof. Karin Sandstrom's Team Nearby Galaxy group.

I am from Taiwan, where I grew up and finished my bachelor studies in physics (National Taiwan University). I play badminton. Happy to bring anyone who visits ASIAA for some badminton games. I like ACG (Japanese Anime, Comics and Games) in general. Recently stepping into building Gunpla. Also likes to talk about history (especially East Asia) and economics.
