Bee Lab Graduate Students
Katherine Hagan is a master’s student in the Honey Bee Program of the Entomology Department of the UGA College of Agricultural & Environmental Sciences (CAES).
Hailing from Whitesville, Kentucky, Katherine earned her Bachelor of Arts in Environmental Studies from Centre College in Danville, Kentucky. While working on a class project, Katherine became fascinated with honey bees and propelled herself into the world of entomology, starting with an internship in Dr. Daniel Potter’s lab at the University of Kentucky. There, she assisted in the identification of over 10,000 bee genera from the Ohio Valley Region.
While interning at the University of Kentucky, Katherine accepted a study abroad in Mérida, Mexico, where she worked with a local organization to develop information on the Melipona beechi, a stingless bee species of cultural and ecological importance in the Yucatán. Her interest in pollinator research accompanied her to an internship position at National Park Service in Washington D.C., where she first served as a Biodiversity Youth Ambassador for the National Park Centennial and 10th annual Bioblitz. Finishing up her degree at Centre College, Katherine moved to New York to work for the American Museum of Natural History and the New York Botanical Gardens. The outstanding reputation of the Honey Bee Program and the outreach of Dr. Keith Delaplane and Jennifer Berry attracted Katherine to UGA, and where she hopes to obtain her masters in honeybee research, specifically within the sectors of polyandry and social evolution.
In her free time, Katherine enjoys spending time outdoors: running with her dog, Catalina, hiking, and biking. She also enjoys reading and plans to read a book a week for the upcoming year. Katherine is an avid indoor volleyball player and was a varsity athlete throughout her four years at Centre College. She remains involved with the volleyball community as a coach for Classic City Volleyball and as an alternate player for local organizations.

Brett Nolan was a PhD student in the Honey Bee Program of the Entomology Department of the UGA College of Agricultural & Environmental Sciences (CAES).
Born and raised in Seneca, South Carolina, Brett’s colors are orange and purple - not red and black. He earned two science degrees from Clemson University: a Bachelor of Wildlife Biology and a Master of Entomology. While working at the Clemson bee lab during his undergraduate studies, he became interested in bees and served as an undergraduate research assistant in 2003 under Dr. Mike Hood - where he studied improved trapping methods for Small Hive Beetle (Aethina tumida) control.
While working on a joint UGA-Clemson research project, Brett was introduced to our UGA Honey Bee Program, and, upon finishing his master’s degree, moved the 60 short miles to Athens to continue his education in Bulldog country. His current research focuses on the host-parasite relationship between honey bees and varroa mites (Varroa destructor). In particular, he is looking at the transmission and virulence of varroa between honey bee colonies as related to colony distance and apiary density. In addition to his own studies and research, Brett regularly makes time to help with general fieldwork, lab work and brainstorming sessions at the Bee Lab, as well as serves as an instructor at the annual Young Harris - UGA Beekeeping Institute.
Brett is married to Emily Nolan, and they have three daughters: Lucy, June, and Camille. His hobbies and interests involve being outdoors: hiking, camping, fishing, and hunting. In his younger years, Brett played soccer; today, he coaches his 5-year-old daughter’s soccer team. And, when he can get a break from the grind of graduate school and work, he enjoys quite a reputation for expert grilling/smoking skills on the barbie and deep-frying delicious, dry-rubbed turkeys.

Avry Pribadi is a Master Student in the Honey Bee Program of the Entomology Department of the UGA College of Agricultural & Environmental Sciences (CAES). He started in Spring 2017 and plans to finish in December 2018.
Originally from Indonesia, a country crossed by the equator, Avry has a strong preference for summer temperatures. He finished his undergraduate degree in Zoology from General Soedirman University. For over ten years he has been working for Forestry Research and Development, a division of the Ministry of Forestry of the Republic of Indonesia. In Indonesia, he conducted research and extension projects with species of honey bees, such as Apis cerana, Apis dorsata, and many species of stingless bees. He also worked with insect pests and biodiversity in tropical forests.
After joining the UGA Honey Bee Lab, he studied the interaction between mating number in queens and parasitic mite (Varroa destructor) infestation on bee mortality. In addition to his own studies and research, Avry regularly makes time to help with general fieldwork, lab work, and brainstorming sessions at the Bee Lab.
Avry is married to Delvia Roza, and they have one daughter, Agnyssya. His hobbies and interests involve being outdoors and learning about public speaking. When he was young, he had a band and played keyboard.

My research was an attempt to quantify the pollination efficacy of the exotic honey bee (Apis mellifera) and native pollinators such as Halictidae, Bombus spp., Xylocopa spp., and Peponapis spp. under different levels of floral competition. This research also examined the effects of floral competition on pollinator diversity. Crimson sweet watermelons (Citrullus lanatus) served as the model plants for measuring pollinator efficacy and sunflowers (Helianthus annuus) as the model competitors.
