Hideyuki Hotta is a professor at the Institute for Space-Earth Environmental Research at Nagoya University, a position he has held since April 2023. He earned a Bachelor of Science, Master of Science, and Doctor of Science from the University of Tokyo, completing his doctorate in 2014. His earlier career includes roles as a JSPS DC1 fellow from 2011 to 2014, a JSPS fellow abroad and scientific visitor at HAO/NCAR from 2014 to 2015, tenure-track assistant professor at Chiba University from 2015 to 2020, assistant professor at Chiba University in 2020, and associate professor at Chiba University from 2020 to 2023.
Hotttas research centers on solar and stellar physics, with emphases on thermal convection and dynamo processes in solar and stellar interiors, sunspot formation, and the development of numerical simulation codes for high-performance computing. He has authored or co-authored publications including the 2021 paper Solar differential rotation reproduced with high-resolution simulation in Nature Astronomy. Hotta has received several honors, such as the Commendation for Science and Technology by the Minister of Education, Culture, Sports, Science and Technology Young Scientists Award in 2022, the Astronomical Society of Japan Young Astronomer Award in 2021, the AAPPS-DPP Young Researcher Award in 2018, and earlier encouragement awards from the University of Tokyo. He maintains memberships in the Astronomical Society of Japan and the Japan Geoscience Union and has presented numerous invited and plenary talks at international meetings on topics including solar dynamo models and stellar convection.
