About Me

My name is Ting Zhang, a.k.a., happygirlzt. I am a research scientist at SMU since Feb 2024. Prior to this, I defended my doctoral dissertation titled "Supporting Software Engineers with Large Language Model-Based Automation" on 13 Dec 2023. I was fortunate to be advised by Prof. David Lo and Prof. Lingxiao Jiang. Previously, I got my Master degree in Information Systems from Nanyang Technological University and Bachelor degree in Computer Science and Technology from Sun Yat-sen University (SYSU).

Research Interests

My research aims to support software developers in (1) understanding the sentiment expressed in software artifacts (ICSME'20, ICPC'22), (2) enhancing software development efficiency and effectiveness (ICSME'22, ASE'22, TOSEM'22, SANER'23, MSR'23).

I enjoy cycling, running, and swimming. I also love playing the sports games on Nintendo Switch. I was a member of the SMU Aquathlon team and the SYSU rowing team. During my undergraduate studies, I was fortunate to represent SYSU in several national and international-level rowing competitions. Check out the moments.
