Hans Thybo (born 19 February 1954) is a Danish geophysicist and geologist. He is President of International Lithosphere Program since 2017{{cite web|title=International Lithosphere Program | url=https://ilp.nju.edu.cn/43698/list.htm}} and currently employed by the Chinese Academy of Geological Sciences (CAGS).

Early life and education

In 1978, Thybo earned a Bachelor of Science (BSc) degree in Mathematics and Physics from Aarhus University, Denmark. In 1980, he completed his studies at the Delft University of Technology, the Netherlands. He earned two more degrees from Aarhus University: a Master of Science (MSc) in geophysics in 1982 and a PhD in geology in 1987.{{cite web|title=CV, Hans Thybo |url=https://web.itu.edu.tr/thybo/Thybo-CV.pdf}}

Professional career

Hans Thybo was a professor of geophysics at the Geological Institute and the Institute for Geography and Geology at the University of Copenhagen for 33 years, as well as at the Centre for Earth Evolution and Dynamics.{{Cite web|last1=Sæl|first1=Visiting address ZEB-buildingSem|last2=Evolution|first2=s vei 2A 0371 Oslo Mail address Centre for Earth|last3=Phone|first3=DynamicsPostbox 1028 Blindern N.-0315 OSLO Norway|last4=CEED|first4=e-mail +47 22 85 40 97 Contact|title=Home – The Centre for Earth Evolution and Dynamics|url=https://www.mn.uio.no/ceed/english/index.html|access-date=2021-09-15|website=www.mn.uio.no|language=en}} at University of Oslo. He is a professor at the Eurasia Institute of Earth Sciences{{Cite web|title=İTÜ {{!}} Eurasia Institute of Earth Sciences|url=https://eies.itu.edu.tr/en|access-date=2021-09-15|website=Avrasya Yer Bilimleri Enstitüsü|language=en}} at Istanbul Technical University, a 1000 Talents Professor at the School of Earth Sciences at China University of Geosciences, Wuhan, and a Distinguished Professor at SinoProbe Laboratory at Chinese Academy of Geological Sciences, Beijing. He was elected head of department at the Geological Institute and member of the board of Geocenter Copenhagen.

He was a professor at Department of Geosciences and Natural Resource Management{{Cite web|last=IGN|date=2005-03-10|title=Institut for Geovidenskab og Naturforvaltning|url=https://ign.ku.dk/|access-date=2021-09-15|website=ign.ku.dk|language=da}} until he was dismissed from his chair in 2016 for allegedly pressuring a postdoc to criticize department management and for using his personal email for work purposes.{{Cite journal |last=Schiermeier |first=Quirin |date=2016-12-05 |title=Sacking of prominent geoscientist rocks community |url=https://www.nature.com/articles/nature.2016.21095 |journal=Nature |language=en |doi=10.1038/nature.2016.21095 |issn=1476-4687 |s2cid=186102842|url-access=subscription }}

Thybo disputed the causes of his firing, and the researcher in question stated that he did not feel pressured.{{Cite web|date=2017-11-27|url=https://uniavisen.dk/en/sacked-geology-professor-thybo-speaks-out/#:~:text=Hans%20Thybo%20was%20to%20be,Copenhagen)%20to%20get%20him%20to|website=University Post|language=en | title=Sacked geology professor Thybo speaks out }} Thybo challenged the dismissal in court, which ruled the dismissal illegal, but the case was settled with Thybo receiving six months salary, which was the maximum possible according to the mutual agreement between Thybo's professional organisation and the University of Copenhagen, whereas the agreement did not allow for a verdict that the illegally dismissed professor should be reinstated into his position.{{Cite web|date=2017-11-27|title=Sacking of top geologist Hans Thybo was unjustified|url=https://uniavisen.dk/en/sacking-of-top-geologist-hans-thybo-was-unjustified/|access-date=2021-09-15|website=University Post|language=da}}

Hans Thybo has published more than 250 papers in international peer-reviewed journals and has been promoter of more than 40 PhD, 80 MSc and 50 BSc students. He has been leader of several geoscientific research programmes and he has been field expedition leader to e.g. the ice sheet in Greenland, east Africa and Siberia. He initiated several pan-European research programmes with east–west collaboration after the end of the cold war. His research includes the discovery of ca. 2 billion year old plate tectonic structures,Abramovitz, T., Berthelsen, A. and Thybo, H., 1997.
