After five years, Prof. Higashiguchi (Utsunomiya University, Japan) returned to Belfield Campus.
After five years, Prof. Higashiguchi (Utsunomiya University) returned to the Belfield Campus, and his research collaboration with the UCD Physics team (Prof. Gerry O’Sullivan and Prof. Padraig Dunne) is going from strength to strength.
Here’s a list of recent publications, derived from their collaboration.

Utsunomiya University is a national university set up in 1949 by integrating three institutions - Utsunomiya Agricultural and Forestry College, Tochigi Normal School and Tochigi Normal School for Young People. Utsunomiya is one of the best technological universities in Japan. Utsunomiya University is globally well-known for its optics and weed science research ((opens in a new window)https://www.utsunomiya-u.ac.jp/en/). Prof. Yukitoshi Otani (Center for Optical Research and Education (CORE), Utsunomiya University) also visited Prof. Dunne in February 2024.
In 2017, as part of our celebrations to mark the 60th anniversary of the Ireland-Japan diplomatic relations, the School of Physics, UCD & Utsunomiya University held a joint seminar ‘Extreme Ultraviolet Source Development for Lithography, Surface Morphology & Water Window Imaging’, which was supported by the UCD Japan Group.
