Openings
I will be on leave from Berkeley and will join Caltech on July 1, 2026. As a result, all new graduate students and postdoctoral scholars will be admitted through Caltech's application and admission system.
Postdoctoral Scholar:The Computing + Mathematical Sciences (CMS) Department at Caltech invites applications for one Postdoctoral Scholar position under the supervision of Professor Lin Lin. The position will focus on the development and analysis of quantum algorithms, with particular emphasis on the following areas:
- Open quantum systems
- Experimentally realizable quantum advantage
- Interplay between classical and quantum statistical physics
- Non-Markovian dynamics
Given the highly interdisciplinary nature of the work, we welcome candidates from diverse backgrounds with PhDs in broadly related fields. The successful candidate should demonstrate the ability to learn new tools independently and efficiently. A strong publication record in quantum algorithms is highly desirable.
All applications should be submitted online. Candidates should prepare and upload the following documents through the application portal:
https://www.cms.caltech.edu/about/positions/computational-mathematics-x
If you would like to be considered for the IQIM Fellowship, please note that this does require a separate application and you should mention my name in your application.
All applications must be submitted through the websites listed above. Please do not send application materials directly to me via email.
Graduate students:
All graduate applications must be applied through the Computing + Mathematical Sciences (CMS) Department's application portal. Please do not send application materials directly to me via email.
Internship:
Unfortunately, during 2025--2026 (including 2026 summer), there are currently no internship positions available for undergraduate or graduate students.
