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 invidual telescopes!
As a Machine Learner, I am specialised at a variety of machine learning and AI techniques to accelearte 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.
