About this position
Keio University School of Medicine is recruiting a Project Assistant Professor / researcher-equivalent fixed-term faculty member for the Mitsuhiro Sakaguchi Memorial Chair in Signal Research in Tokyo, Japan.
The position is centered on structural biochemistry, with a strong focus on cryo-electron microscopy (Cryo-EM), MicroED, protein expression and purification, and structural analysis of gut microbiota-related proteins and metabolites. The project, in collaboration with Associate Professor Wataru Shifutani, aims to understand and apply the principles of gut microbiota operation for extending healthy lifespan. Research themes include structural analysis of metabolite-related proteins such as enzymes and receptors including GPCRs, as well as structural determination of gut microbiota-derived metabolites. The work will be carried out in close cooperation with the Keio University Center for Human Biology, Microbiota, and Quantum Computing (Bio2Q), which provides a state-of-the-art Cryo-EM Core.
The lab notes that it is newly established but already fully equipped, and applicants may also contribute to other ongoing projects or propose their own themes depending on budget and discussion. The posting emphasizes proactive, collaborative researchers who can independently troubleshoot structural analysis problems. Experience with protein purification or Cryo-EM is required; prior MicroED experience is not necessary.
Eligibility: doctoral degree required. Candidates expecting to receive the doctorate on or after 2027-04-01 are also eligible if the timing is delayed by circumstances.
Funding and terms: annual salary starts at 5 million yen and is negotiated based on experience and other factors. The appointment is fixed-term and renewable annually; the posting states renewal is guaranteed until March 2030, with possible extension depending on budget. Online interviews are available, and travel expenses may be reimbursed for applicants from outside Tokyo.
Deadline: applications must arrive between 2026-09-28 and 2027-03-31, with the position closing early once a suitable candidate is found.
How to apply: submit the required documents via the JREC-IN portal online application system. Required materials include a CV, publication list, research history, statement of motivation and future plans, details of experience with protein structure analysis/Cryo-EM/small-molecule structure determination, and contact information for two referees.
