Lab Members

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 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. Harmen P. Hendriksma

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 started his postdoc position in Rehovot, Israel in August of 2012 on the topic of the nutritional balancing done by honey bees.

    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.

    Yael Katz

    M.Sc. 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).

    Tal Erez

    M.Sc. Student

    Co-supervisor: Dr. Oz Barazani

    Tal has a B.Sc. in Agriculture from the Hebrew University of Jerusalem. Her M.Sc. research focuses on preferences of honey bees and decisions that they make when they are pollinating two morphs of the same flower.

    Tania Masci

    Laboratory Technician

    Tania has worked at the Faculty of Agriculture since 1997. She is a professional bee brain surgeon! She is currently working with Yael Katz on the effect of fatty acid nutrition on learning and memory. She has a B.Sc. in Biology from Bar Ilan University.

    Karmi Oxman

    Laboratory Technician

    Karmi has been a technician in the lab since June 2013. She is interested in nutrient balancing and foraging preferences of honey bees, as well as the transfer of information via honey bee dances. She has a B.A. in Biology and Environmental Studies from Oberlin College. Karmi is also an illustrator .

    Dan Eliahu

    Dror Friedman

    Lab Alumni

    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.
