I am a first-year second-year third-year Ph.D. student in the Department of Computer Science at University of Southern California (USC) with Prof. Mohammad Soleymani of IHP-Lab. I'm also a student researcher at TikTok-ByteDance Seed Vision Research, working with Dr. Yichun Shi and Dr. Peng Wang. During my PhD at USC, I'm fortunate to have collaborated with Prof. Gordon Wetzstein from Stanford University, Prof. Narendra Ahuja from University of Illinois Urbana-Champaign, and their students.
I was a Research Scientist Intern at TikTok-ByteDance Intelligent Creation Lab, working with Dr. Hongyi Xu and Dr. Linjie Luo during 2024 summer, and with Dr. Yichun Shi and Dr. Xiao Yang during 2023 summer.
Research opportunities:
For USC undergraduate students: We have openings for interns through CURVE program. Usually we recruit students (first-time researchers and continuing researchers) during Fall and Spring semesters, please apply early.
For USC master students: Please directly email Prof. Mohammad Soleymani for such inquiries. It would be better if you've attended CSCI 535 and obtained a good grade.
For all other students outside USC: we usually don't have openings during Fall and Spring semesters, but Prof. Mohammad Soleymani sometimes recruits good candidates (Undergrad/Ms/visiting PhD) during the Summer. Email him for further details.
I am happy to collaborate and/or answer questions about my research and my previous study at TUM and current PhD program at USC. If you are interested in research collaboration or have any inquiries about my experience, please send me an email.
