Prof. Sharoni Shafir

Sharoni has been the director of the B. Triwaks Bee Research Center since 1998. He advocates a multidisciplinary approach to promoting bee health and bee pollination services. He is especially interested in bee nutrition and bee cognition, specifically aspects of perception and decision making that relate to foraging and pollination. He has a BA and PhD from Stanford University, an MS from University of Florida, and was a postdoctoral fellow at The Ohio State University.

Dr. Danny Minahan
Postdoctoral Fellow 

Danny has been a postdoctoral researcher at the B. Triwaks Bee Research Center since 2019. He received his BA from the University of Colorado-Boulder, and his PhD from the University of Wisconsin-Madison. His dissertation work examined the link between pollen foraging patterns and resource preferences by honey bees and bumble bees, to identify the potential for competition and resource partitioning. As pollen is a primary source of nutrition for bees, he has expanded on this work during his postdoc studying the effects of unbalanced nutrition, specifically that of omega 6 and omega 3 fatty acids on the behavior of honey bees and bumble bees. Danny applies modern barcoding and computer vision approaches to examine these processes at the level of individuals and colonies. In his free time, he enjoys long distance running and spending quality time with his dog Rupee.

Meray Kadee

Ph.D. student

Meray is a Ph.D. candidate in the Agroecology and Plant Health program at the Hebrew University of Jerusalem. He joined the lab as a research assistant in early 2017, and subsequently completed his Master's degree, co-supervised by Prof. Oz Barazani, where he studied the effects of honey bee pollination on Eruca sativa. Currently, Meray's research focuses on understanding the effects of dietary essential fatty acids on honey bee cognition and brain characteristics, with the goal of promoting pollinator health and developing sustainable beekeeping practices.

Zuzana Sykorova

Internship Student

Zuzana is an internship student from Czechia. She received her bachelor's degree in the field of inorganic non-metallic materials at the University of Chemistry and Technology in Prague. She is currently studying a master's program at the University of Life Sciences in Prague, where she deals with monitoring the honey bee as a biomonitor of the environment that was affected by the mining of brown coal during the communist regime, and this mining is still ongoing in many places in the Czech Republic.

Yael  Arien

Ph.D. Student

Co-supervisor: Dr. Arnon Dag

Yael has a B.Sc. in Agriculture from the Hebrew University of Jerusalem, and continued for a direct PhD program. She studies the importance of essential fatty acids in honey bee nutrition for their development, survival, and learning and memory. Yael uses methods such as proboscis extension response (PER) conditioning and electroantennogram (EAG) recordings.

Dr. Raquel Teixeira de Sousa

Postdoctoral Fellow

Raquel has a Bsc in Applied Biology from the Universidade do Minho (Braga, Portugal) and a Msc in Toxicology and Ecotoxicology from the Universidade de Aveiro (Aveiro Portugal). It was her first beekeeping endeavors in Portugal that led her to pursue a PhD in honey bee nutrition and feeding behaviour. In 2013, she enrolled a PhD Program (GABBA, Universidade do Porto, Portugal) that paved the opportunity to engage her research in Wright’s Lab in Newcastle University (UK). Her PhD research was on behavioural regulation and feeding preferences of mineral salts in adult worker honey bees. Raquel has recently started her first post-doc position (2018) to follow up her previous research in a joint collaboration between Wright’s Lab and Shafir’s Lab in the HUJI (Rehovot, Israel).

Dr. Sofia Bouchebti

Postdoctoral Fellow

Sofia investigates how ratios of macronutrients (proteins, carbohydrates, and fatty acids) affect various measures of performance in honey bees (such as survival, learning, and memory), and whether bees are able to balance their intake of nutrients as a function of different social parameters. During her PhD in the University Paul Sabatier Toulouse III, she has studied the foraging behavior of the leaf-cutting ant Atta laevigata, both in laboratory (in France) and in the field (in Brazil).

Rui Goncalves

Research Associate

Rui has a BSc in Applied Biology from the Universidade do Minho (Braga, Portugal) and a Joint European MSc in Environmental Studies (JEMES) between Portugal, Spain, Denmark and Germany. His MSc research focused on the development of a low-cost MFC (micro fuel cell) reactor using exoelectrogenic bacteria in the Universitat Autonoma de Barcelona (Spain) between 2009-2011. Soon after in Northern Portugal, he was introduced to beekeeping, co-founded a beekeeping association and a beekeeping company and ever since, Rui has been a devoted beekeeper without borders. In 2016, Rui conducted a market research in bee nutrition and beekeeping practices across the globe as an ICURE fellow. He joined Shafir’s Lab in Rehovot as part of a joint collaboration with the Wright’s lab (Newcastle University – UK) to improve bee nutrition.

Ira Treidel

Research Associate

Ira is a passionate beekeeper, right-hand man of Haim. He has a B.Sc. in Agriculture from the Hebrew University of Jerusalem and he joined the laboratory four years ago. In addition to his beekeeping work, he is involved in many different research experiments.

Dr. Harmen P. Hendriksma

Former Postdoctoral Fellow

Harmen is a devoted beekeeper and researcher. He studied ecosystem biology at the University of Wageningen, in Holand. Thereafter, he was a professional beekeeper for 4 years until he started his PhD in Bayreuth and Wuerzburg in Germany. His PhD research was on honey bee risk assessment with transgenic maize. Harmen was a postdoc in the B. Triwaks Bee Research Center from 2012 – 2015, working on the nutritional balancing done by honey bees.
