Obituary

Professor Ebrahim Ghasemi-Nejad (1960-2020)

Ebrahim Ghasemi-Nejad died unexpectedly in Tehran on 2020/12/05 at the age of 60. He was professor of Paleontology in School of Geology, University of Tehran, since 1997. He received his BSc. in Geology from Mashhad University in 1986 and his MSc. in paleontology from Tarbiat Moallem University, in 1990. Then he continued his education in Canada and received his Ph.D. in Paleontology in 1996 from University of Saskatchewan. He was a member of several scientific committees in Iran and the editor-in-chief of the Geopersia, which with his management became a WOS journal.

Sadly, we lost a respectful, generous and ethical gentleman, who was a caring father and husband, an enthusiastic teacher cherishing his students, a knowledgeable researcher and devoted scientist, and above all a beloved wonderful colleague and friend.

May the departed soul rest in peace and May God give us and his family more strength!
