  • 08/07/2022 Three papers are accepted in ECCV 2022. Congrats to former Intern Jiale Li, Yu Hong, and Postdoc Dr. Xuebin Qin. Papers: CMKD (Oral presentation, acceptance rate: 2.7%), Self-Distillation,  DIS.


Dr. Hang Dai is a Lecturer in Machine Learning at the School of Computing Science (IDA Section), University of Glasgow, Scotland, UK. He holds a Ph.D. in Computer Science from the University of York, where he built a 3D morphable model of human heads (LYHM) from the Headspace dataset. He was awarded a three-year full Oversea Research Scholarship from the University of York during his Ph.D. study.

He is a regular publisher in top AI/CV conferences like CVPR, ECCV, ICCV, ACM MM and etc. He also wins competitive top conference challenge awards, such as CVPR 2022 Waymo Autonomous Driving Challenge and ECCV 2020 Command for Autonomous Vehicles Challenge. He leads his research group to formulate the problem of highly accurate dichotomous image segmentation towards entering an era of demanding highly accurate outputs from AI algorithms to support delicate human-machine interaction and immersed virtual life and deliver the DIS benchmark to the community.

Ph.D. Vacancies.

I am looking for highly motivated and competitive Ph.D. candidates. Publications in top conferences like CVPR, ECCV, and ICCV are a PLUS. For Ph.D. topics, please refer to the section of Supervision. If you are interested, drop me an email with your CV. I will reply when the Ph.D. applicant meets the requirements. 

[Hot!] One full Ph.D. studentship at Home Rate is available for the coming academic year (23-24). Qualified international students need to pay for the fee differences. This position is very competitive. Application Deadline: January 2023.

[CSC Ph.D. Studentship] Deadline: January of the academic year.

• What is covered: if accepted by the CSC, the CSC covers the stipend. The college’s graduate school endeavors to match this with a tuition waiver.
• Eligibility of Student: student has to be Chinese and has to agree to the CSC’s terms which include the requirement to return to China after completing their Ph.D.

Students who are not already in Glasgow, and who are affiliated with partner institutions are encouraged to apply for CSC Ph.D. studentship.

[Other scholarships] Deadline is usually January of the academic year. CDT studentships’ deadline is decided by the CDT team. More scholarship opportunities can be found here: University of Glasgow - Schools - School of Computing Science - Postgraduate research - Prospective students - PhD projects and funding opportunities.

[Ph.D. application process] Please refer to University of Glasgow - Schools - School of Computing Science - Postgraduate research - Prospective students. For international students, please make sure that you have the documentation that you meet the language requirements for the College of Science & Engineering before you start the application process.
