Dr Ting-Yun Cheng
(aka Sunny)

Hello! I am Sunny; a postdoctoral researcher at the Centre for Extragalactic Astronomy, Durham University. My research is all about galaxies! Galaxies are cosmic archelogical sites; I explore them to understand not only the evolutionary history of galaxies but also the story of our Universe. In my research, I apply a variety of machine learning (ML) techniques and develop novel ML algorithms to uncover patterns and insights within the vast sea of data.

As an Astrophysicist, my research investigates (i) how galaxies are formed and evolved in the early Universe and (ii) what mechanisms transform the structures and physical properties of galaxies across cosmic time. I try to answer these questiosn using large-scale survey data including images and spectra of millions of galaxies, and data collected from invidual telescopes myself!

As a Machine Learner, I am specialised at a variety of machine learning techniques to accelearte and improve the analyses of the coming plethora of astronomical datasets. In addition to the improvement of accuracy and efficiency to astronomical analyses, I also develop machine learning techniques to provide a new insight into galaxy structures.
