Daniel Sher is a Professor of Marine Biology at the Leon H. Charney School of Marine Sciences, University of Haifa (Israel). Daniel completed his undergraduate and PhD studies at the Hebrew University of Jerusalem, followed by postdoctoral studies at MIT. His main research interest lies in Aquatic Chemical Ecology and Microbial Oceanography – understanding the way aquatic organisms communicate through chemistry, the chemicals that mediate these interactions, and the way these interactions and chemicals affect entire ecosystems. Most of the people in his lab currently study how Prochlorococcus, a tiny marine cyanobacterium and the most abundant photosynthetic organism on Earth, interacts with co-occurring marine bacteria. Other projects in the lab focus on understanding the causes for jellyfish blooms (including whether their associated bacteria are involved in bloom growth and decline), and on developing methods to use natural marine bacterial communities as biosensors for pollution. Daniel is also a member of the steering committee of the University of Haifa Data Science Research Center, and of the outreach committee of the School of Marine Sciences. He is married, has three kids and a dog, and in his spare time loves hiking, cooking and photography.
