Guy Bloch's research focuses on understanding the evolution of sociality and the physiological and molecular basis of social behavior using bees (mainly bumble bees and honey bees) as the main research model. The main research topics include understanding the interrelationships between biological clocks, sleep control and social behavior, the influence of hormones, especially juvenile hormone (JH), on the evolution of sociality and social behavior, and diciphering the sociobiology of bumble bee colonies, including mechanisms determining body size and caste determination. Some of his group findings include the characterization of the molecular clockwork of bees, the discovery and characterization of remarkable socially regulated plasticity in the biological clock allowing bees to be active around the clock[1][2][3]. Additional studies have shown that the JH has a central effect on social behavior in bees, but the effect is different in bumble bees and honey bees[4][5]. Also, Bloch's research group was the first to show that RNA editing may affect social behavior[6]. The group also characterized charred honey bee remains in the oldest hives ever found in the world[7].

Guy Bloch (born May 23, 1962) is an Israeli scientist, Full Professor at the Alexander Silverman Institute of Life Sciences at the Hebrew University of Jerusalem. His research focuses on the evolution and the molecular and physiological basis of social behavior and sociality in bees.

Biography

Guy Bloch was born and raised in Kibbutz Nachshon and Moshav Kfar Bilo in Israel. He holds a bachelor's degree in Biology and MSc and a PhD degrees in Zoology from Tel Aviv University. During 1997-2001 he was post-doctoral fellow with Prof. Gene Robinson at the University of Illinois at Urbana-Champaign (UIUC). In 2001, he returned to Israel and founded the research group for the study of social behavior in bees in the Department of Ecology, Evolution and Behavior at the Alexander Silverman Institute of Life Sciences in the Faculty of Natural Sciences at the Hebrew University. In 2008 he was invited to serve as a Visiting Professor at the University of Auckland in New Zealand and in Arizona State University (ASU). In 2015, he won the Clark-Way Harrison Visiting Scholar Award and spent a year at Washington University in St. Louis. Prof. Bloch held a number of positions at the Hebrew University and other organizations, including Head of the Department of Ecology, Evolution and Behavior (2009-2015), member of the Hebrew University Senate, Head of the Hebrew University fellowship committee, and Head of the Institute of Life Sciences (from 10/2022).

Research

Guy Bloch's research focuses on understanding the evolution of sociality and the physiological and molecular basis of social behavior using bees (mainly bumble bees and honey bees) as the main research model. The main research topics include understanding the interrelationships between biological clocks, sleep control and social behavior, the influence of hormones, especially juvenile hormone (JH), on the evolution of sociality and social behavior, and diciphering the sociobiology of bumble bee colonies, including mechanisms determining body size and caste determination. Some of his group findings include the characterization of the molecular clockwork of bees, the discovery and characterization of remarkable socially regulated plasticity in the biological clock allowing bees to be active around the clock[1][2][3]. Additional studies have shown that the JH has a central effect on social behavior in bees, but the effect is different in bumble bees and honey bees[4][5]. Also, Bloch's research group was the first to show that RNA editing may affect social behavior[6]. The group also characterized charred honey bee remains in the oldest hives ever found in the world[7].
