Ramon Alexander Wyss (born 1 March 1952) is a Swedish theoretical nuclear physicist.^[2] He is a professor emeritus at the KTH Royal Institute of Technology in Stockholm.^[3] He served as Vice President for International Affairs at KTH in between 2002 to 2016.^[4] He held professorships at Peking University and Shanghai Jiao Tong University.^[5]

His research focuses on nuclear structure physics, using simple theoretical models to elucidate complex experimental findings.^[6]

In 1995, he was awarded the Edlundska prize of the Royal Swedish Academy of Science.^[7]

Ramon Wyss was born to Dieter Wyss and Ursula Wyss Daecke.^[8] He became a Swedish citizen in 1973 and earned his Teknologie doktor (PhD) in 1990, followed by a postdoc stay at the Joint Institute of Oak Ridge National Lab 1990-1992. He earned docent promotion in 1994 and in 2006 he was appointed professor of theoretical nuclear physics at KTH.^[9]

Wyss was appointed professor of theoretical nuclear physics at KTH in 2006.^[10][11]

From 2002 to 2016, Wyss served as Vice President of KTH in charge of international education and global partnerships.^[4]

After retiring from KTH, Wyss has worked on interdisciplinary projects linking physics and societal challenges. With Ayşe Ataç Nyberg, he co-founded the European ArtEmis Project in 2022^[12], aimed at building a sensor network to improve earthquake forecasting.^[13]

He currently serves as chair of both the governing and science boards of the project. He was the interim director of the Center for New Energy Technology Oskarshamn (CNETO).^[14]

He was co-chair for the International advisory board of Beijing Jiaotong University and in 2021 he was appointed to the international advisory board of Shanghai Jiao Tong University.^[11]

In 2009, he was reappointed Vice-President for international projects at KTH.^[5]

Research and Opinions

Wyss's theoretical contributions in nuclear physics include simplified microscopic-macroscopic approaches and rotational models, notably in studies of backbending and high-spin band structures.^[15][13]

His research has centered on nuclear structure^[16], including rotational motion^[17], backbending phenomena, particle decay^[18] and the development of nuclear models linking experimental and theoretical approaches.

He co-authored research on neutron-proton pairing in nuclei and other mass systematics, reinforcing the effectiveness of accessible models in describing complex nuclear behaviors.^[19]

In Sweden, he engaged in the debate for nuclear power as an energy source reducing CO2 emission.^[20]
