The primary focus of our current research is the cellular stress responses of the honey bee, a species that is crucial to agricultural and ecological systems. Honey bee colonies in the United States and elsewhere have suffered from an increased rate of die-off in recent years, likely stemming from a complex set of interacting stresses that include nutritional deficiencies due to loss of appropriate forage, chemical poisoning from pesticides, changes to normal living conditions brought about through large-scale beekeeping practices, myriad environmental changes due to climate change, and infection by insect parasites and pathogenic microbes.

My research program now focuses on two main questions to help understand the challenges facing honey bee colonies and to generate solutions for use by beekeepers in the field. First, we believe that an important aspect for understanding how the stressors listed above impact honey bees requires defining specific common cellular processes that are impacted by multiple stressors. To that end we have focused on how honey bees respond to stresses thought to play a role in honey bee health and disease at the cellular level. Specifically we have begun to characterize the pathways of the proteostatic network in bees. Second, we have focused more directly on one stressor, the infection of honey bees by the microsporidia species Nosema ceranae. We have begun to characterize the cellular responses to these same stressors in this key pathogen of the honey bee, focusing again on the pathways of the proteostatic network. The goal is to uncover elements that are unique to N. ceranae, and thus offer avenues for the development of novel therapeutics that have minimal impacts on the honey bee hosts.

Using the honey bee as a model also promises to improve our understanding of the dialogue between humans and our environment and will help move our society toward a more sustainable future.

Today we sit down with Eliana Elikan, a junior Biology major and research assistant in the Snow Bee Lab. Under the mentorship of Professor Jon Snow, she has been focusing on a parasite infecting the bees called Nosema ceranae, which is believed to be acting in conjunction with several stressors to drive the decline in honey bee populations.

Today, we sat down to chat with the two new faces on the 10th floor of Altschul: Mehrose Ahmad (BC '21) and Corey Marshalleck. As lab technicians for Professors Allison Lopatkin and Jon Snow respectively, Mehrose and Corey discuss research, mentorship, and life outside of Altschul.
