Biography

Dr. Taotao Cai is a Senior Lecturer in Computing at the University of Southern Queensland (UniSQ) and an Honorary Lecturer at Macquarie University. His primary focus is on research and teaching in the field of Graph Query. He completed his Ph.D. degree from Deakin University in 2020 after spending two years at The University of Western Australia (Jan 2017 - Mar 2019) and over one year at Deakin University (Mar 2019 - July 2020) during his Ph.D. studies. In addition to his Ph.D., Dr. Cai also holds a Master's degree in Computer Science from Shenzhen University, which he earned in 2016.

Prior to joining the faculty at UniSQ, Taotao held positions as a Postdoctoral Research Fellow at Macquarie University (Mar 2021 - Jan 2023) and an Associate Research Fellow at Deakin University (July 2020 - Feb 2021). During this time, he made significant research contributions, which have been published in leading international conferences and journals such as IEEE ICDE, IEEE TKDE, and Information Systems. Notably, his 2020 paper in Information Systems was recently selected as one of the most influential papers of the past decade, to be featured in the journal’s 50th Anniversary Virtual Special Issue—a recognition that highlights the international impact of his work. As you know, Information Systems Journal is a CORE A* ranked outlet and one of the top-tier journals in the information systems discipline. Being recognised in this way is a significant honour, reflecting the impact of Dr. Cai’s work on the global IS research community.

In addition to his research, Dr. Cai has gained considerable teaching experience in both online and offline settings. He has served as a Course Examiner, Lecturer, and Guest Lecturer in various units and courses, and has received positive feedback from students for his engaging teaching style and ability to effectively convey complex concepts.
