*While applicants can indicate for which position they wish to be considered, it will be determined based on each candidate’s qualifications, research experience and independence.

Job description

Specifics of the job description and work location will depend on the laboratory (see [Laboratory] section) to which the Applicant will be assigned. Applicants should mention in their cover letter which iTHEMS laboratories they would like to join based on their expertise and research proposal (see the list (1)-(9) in the [Laboratory] section above), and are encouraged to list more than one laboratory.

Applicants’ research projects will be one of:

(1)Basic interdisciplinary theoretical or computational research in disciplines including physics, biology and life sciences, computer science, information science, as well as theoretical and applied mathematics.
(2)Developing new mathematical and statistical approaches to uncover the evolutionary forces acting on our genomes
(3)Scientific research on the mechanisms behind AI, and applications of AI to basic science
(4)Applications of Mathematics to other research fields
(5)Promoting research in fundamental sciences (such as mathematics, physics, chemistry, biology, medical science, and information science) as well as applied sciences utilizing quantum computers.
(6)Integration of information theory, mathematical modeling and machine learning and their application to medical science problems
(7)Deep Learning in Biomedical Sciences
(8)Theory and methods on prediction, control and estimation
(9)Mathematical analysis and modeling of social behaviors

where numbers (1)-(9) above correspond to the same numbers in the [Laboratory] section above.

Applicants will be considered for their chosen laboratory whenever possible, but might be offered a position in a different laboratory as part of the screening process.
