Dr Ting-Yun (Sunny) Cheng
- Astrophysicist & Machine Learner
As an Astrophysicist, my research explores
(i) galaxy structures across cosmic time, (ii) how galaxies are like in the
metal-poor environments and (iii) what mechanisms transform the structures and
physical properties of galaxies. I try to answer these questions using large-scale
survey data including images and spectra of millions of galaxies, and data
collected from individual telescopes!
As a Machine Learner, I am specialised at a
variety of machine learning and AI techniques to accelerate and improve the
analyses of the enormous inflow of astronomical datasets. In addition to the
improvement of accuracy and efficiency to astronomical analyses, I am keen to
understand what machines interpret images and spectra of galaxies, and to use
this knowledge to bring new insights.
