We are seeking talented postdoctoral researchers with expertise in optics, particularly in the areas of optical sensing and fiber optics, from around the globe to join our team. Currently, we are only able to consider candidates who have secured their own funding or are actively applying for external fellowships. In light of the large volume of inquiries we receive asking simply if a postdoctoral position is available without any information on funding, we have decided not to respond to such emails. One example of an external fellowship is the JSPS Postdoctoral Fellowships program, offered by the Japan Society for the Promotion of Science to international postdoctoral researchers. We are willing to support those who plan to apply for this program and join us. If you are interested in this opportunity, please send your academic CV to Prof. Mizuno for consideration. Please note that acceptance into this highly competitive program is dependent on the situation and may not be granted in all cases. If accepted, you will have the opportunity to thrive in a supportive research environment where you can fully dedicate yourself to your work.
