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.

Haim Kalev

Lab Manager and Beekeeper

Haim has a B.Sc. in Agriculture from the Hebrew University of Jerusalem. He has been a technician and beekeeper at the B. Triwaks Bee Research Center since 1997. Haim is very involved in education and collaboration with the international community of beekeepers. He has led many courses in subjects such as beekeeping for beginners, modern apiculture management (honey by-products and pollination), commercial beekeeping, and artificial insemination of queens. His courses take place all over the world, including Eritrea, Nigeria, Ethiopia, Uzbekistan, Rwanda, and El Salvador.

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).

Yael Katz

Ph.D. Student

Co-supervisor: Dr. Arnon Dag

Yael has a B.Sc. in Agriculture from the Hebrew University of Jerusalem. Her M.Sc. research focuses on the importance of fatty acids in honey bee nutrition, especially on learning and memory. Yael uses methods such as proboscis extension response (PER).

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.

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.

Shlomi Zarchin

Co-supervisor: Dr. Arnon Dag

Shlomi's M.Sc. thesis was on the ability of honey bee (Apis mellifera) foragers to discriminate between pollens according to their fatty acid composition

Nadav Ezra

Nadav's M.Sc. thesis tested the subjective evaluation by honey bees of nectar secondary compounds and their fitness consequences. Specifically, he tested the effect on colony fitness of various components of avocado nectar, which is known to be unattractive to bees. In addition, he assessed the subjective evaluation of honey bees of caffeine in nectar, through analyses of their round dances.
