Born: 1968

Interests: Marine Geology, Paleoclimatology, Sedimentology, Science Policy


Geoscientist at the Woods Hole Oceanographic Institution (Associated Scientist w/ Tenure). Educated in Geology in Romania (Diploma, Bucharest University) and Oceanography in the US (MSc and PhD, State University of New York at Stony Brook).

Leader and participant in research cruises on the Atlantic, Pacific and Indian oceans and land-based expeditions in the Americas, Asia and Europe.

Studies published in leading scientific journals such as Nature, Geology, Nature Geoscience, Proceedings of the U.S. National Academy of Sciences, Geophysical Research Letters.

His contributions reported in National Geographic, Discovery, New York Times, BBC and other mass media venues include: discovery of a new type of delta, the recognition of a fundamental sediment deficit for most river deltas to withstand future sea level rise, the first accurate determination of the age of the Danube Delta, demonstrating the catastrophic effects of deforestation on the evolution of the Danube delta and the Black Sea and analyses of the climatic causes of the development and decline of the ancient civilizations of India.

Giosan was a Honorary Research Fellow at the University of Aberdeen, a CICOR Postdoctoral Scholar at WHOI and a NAFSA Baltic and East European Program awardee at SUNY Stony Brook. He is an Editorial Board member for the journals Anthropocene and Frontiers in Earth Sciences. Giosan is a member of the U.S. Advisory Committee for the International Ocean Discovery Program and a member of the Mississippi River Diversion Expert Panel.

He initiated and co-founded the Ad Astra Association of Romanian researchers in 2000 and published analyses and OpEd texts in leading Romanian media such as "Romania Curata", "Adevarul", "Romania Libera" and "Dilema."
