Keisuke Oshimi

PhD student, Receipient of JSPS DC2 Felloship

Keisuke is working on the development of nanodiamond ODMR/Thermometry system for intracellular temperature measurements. He obtained BComm in 2019 and MSc in 2021 at Osaka City University. He was awarded to OU-Fellowship for 2021-2023 and JSPS-fellowship (DC2) for 2023-2025. He loves playing piano pieces by Beethoven (Moonlight Sonata 3rd Movement, Waldstein Sonata 3rd Movement).


Sara Mandic

PhD student, Receipient of Okayama University Felloship

マンディッチ サラ,大学院生(博士後期課程)OUフェローシップ受給者

Sara is interested in analytical chemistry applications on biological samples. She is investigating thermotaxis behavior of C. elegans, and molecular mechanisms behind it, by combining quantum thermometry with different imaging techniques. Before coming to Japan, she received a Master's degree in Biomedical Sciences/Medical imaging from Maastricht University in the Netherlands.


Muhammad Wahyu Nugraha

PhD student, Receipient of MEXT Scholarship

ヌグラハ ムハマド・ワッユ,大学院生(博士後期課程) 国費外国人留学生

Wahyu primarily works on material sciences. His previous work synthesized photocatalysts, absorbents, membrane composites, and AOPs for water purification. He is currently interested in studying the NPs synthesis, its functionalization, and its effect on the ecological environment. He loves to play strategic board games in his spare time. He received MEng from Universiti Teknologi Petronas in Malaysia.


Mina Tavakkoli

PhD student

タヴァコリ ミナ,大学院生(博士後期課程)

Mina received her MSc in Nanotechnology Engineering - Nanoelectronics from University of Tabriz in Iran. Her latest achievements was published in Plasmonics journal. She primarily works on application of nanodiamond thermometry to cellular thermal analysis. Her research interest is development of nanophotonic biosensors in cell research. She loves art, especially oil painting and chiaroscuro.
