Postdoctoral Scholar Positions, Algebraic Combinatorics and Fundamental Physics Unit

The position

The Algebraic Combinatorics and Fundamental Physics Unit, led by Matteo Parisi, investigates new combinatorial and geometric structures underlying quantum field theory. The group seeks to elucidate how scattering amplitudes and quantum observables arise from total positivity and positive geometry, connecting algebraic combinatorics, algebraic geometry, and high-energy physics.

We invite applications for postdoctoral positions to join this interdisciplinary program. Successful candidates will have the opportunity to work on topics such as cluster algebras, amplituhedra, Landau analysis, Feynman integrals, and related aspects of algebraic combinatorics and geometry in fundamental physics and cosmology. Candidates from pure or applied mathematics, theoretical physics, and related areas are encouraged to apply. Appointments are expected to commence in or after April 2026 and are offered for two years, with the possibility of renewal. The positions are particularly suited for researchers—whether early in their career or more senior—seeking to develop an independent research profile at the interface of mathematics and physics.

OIST provides an exceptionally well-resourced and supportive environment—including generous research-travel funds, relocation and housing allowances, and comprehensive assistance with administrative and daily-life matters. Its modern campus, set amid the natural beauty of Okinawa, hosts an inclusive and vibrant international community and offers a unique cultural experience within Japan.

We value diversity in all its forms and encourage applications from candidates of any background, particularly those traditionally under-represented in mathematics and physics, including women+, LGBTIQ+ individuals, and scholars from diverse socio-economic and cultural backgrounds.

About OIST

The Okinawa Institute of Science and Technology Graduate University was established in 2011 to contribute to the development of science and technology worldwide and to serve as a hub of innovation in Okinawa. OIST is a dynamic new graduate university of science and technology in Okinawa Prefecture, Japan which offers a 5-year PhD program and brings together outstanding researchers from across the country and across disciplines to conduct cutting-edge scientific research.

The university is located on 85 hectares of protected forestland overlooking a beautiful shoreline and coral reefs. The campus is striking architecturally, and the facilities are outstanding. To facilitate multidisciplinary research, there are no academic departments. Outstanding resources and equipment are provided and managed to encourage easy access and collaboration.

English is the official language of the University, and the university research community is fully international, with more than 50 countries represented. OIST is rapidly gaining recognition in the worldwide academic community as a model for excellence in education and research, and our unwavering commitment to scientific and technological innovation is dedicated to generating progress that will fuel Okinawa's economic growth.

Responsibilities
  1. Conduct high-quality research in algebraic combinatorics, geometry, or high-energy physics aligned with the themes of the Unit.
  2. Collaborate actively within the Unit and OIST, as well as with external researchers, to foster interdisciplinary and international exchange.
  3. Present and disseminate research results through publications and presentations at seminars and conferences.
  4. Help shape the intellectual life of the Unit by contributing to seminars, workshops, mentoring, or collaborative initiatives, and by engaging in community or outreach activities when appropriate.
Qualifications

(Required)

  1. PhD in mathematics, physics, or a closely related field by the start date.
