(刘杜钢)

Hello! I am an Associate Researcher in the Guangdong Laboratory of Artificial Intelligence and Digital Economy (SZ) at Shenzhen University. I got my Ph.D. from the College of Computer Science and Software Engineering at Shenzhen University, advised by Prof. Zhong Ming and Weike Pan. Before that, I obtained my Master's degree in Computer Science from Xiamen University and my Bachelor's degree in Mathematics from Fujian Normal University.

I am broadly interested in data mining, data-centric artificial intelligence, and user-centric personalized services, with a special emphasis on enhancing the responsibility in algorithms to provide fair, trustworthy, effective and efficient user-centric information services for various application scenarios. I am open to various kinds of collaborations. If you have any ideas, please contact me.

I am looking for multiple self-motivated Masters and PhD students. If you are interested, please contact me.

For Prospective Students

For prospective Masters and PhD students: I am looking for highly self-motivated Masters and PhD students. If you are interested in working with me, please email me with your CV, transcript, a description of your research interests and experience, and your writting samples (e.g., publications, dissertations, project reports, and so on).

For prospective intern students: I am also exicted to help other students with their research, especially if you plan to apply for higher degrees at graduate schools. Full-time interns will be offered a salary accordingly. If you are interested in working with me, please email me with your CV, transcript, a description of your research interests and experience, and your writting samples (e.g., publications, dissertations, project reports, and so on).
