About Me
Postdoctoral Scholar, Department of Entomology, UC Davis, rlmalfi@ucdavis.edu
Rosemary earned her Ph.D. in Environmental Science (Ecology) from the University of Virginia in 2015 under the advisement of Dr. T'ai Roulston. Her doctoral research focused on the influence that flower (i.e. food) availability and parasitism have on bumblebee (Bombus spp.) population dynamics, and how risks associated with these factors vary among species within a community. Integrating field observations, parasite analysis, colony manipulations, the use of radio frequency technology, and simulation modeling, her work investigated these sources of environmental influence independently and interactively through studies that focus on bumblebee populations and environmental risks present in northern Virginia.
Among the bumblebee parasites she has studied is Nosema bombi, a pathogenic fungus that has been implicated in the precipitous and rapid decline of several bumblebee species across North America. During her graduate studies, she became especially interested in the interaction between bumblebees and one of their parasitoids, the conopid fly. Although the basic biology of this interaction has been described, little is currently known about the ecology of this host-parasitoid relationship, particularly in North America. Over three years, Rosemary worked with undergraduate student collaborators to investigate multiple aspects of this host-parasitoid relationship relating to behavioral ecology, population ecology, and even physiology. You can read more about her past and ongoing research under the "Research" and "People" tabs of this website.
Rosemary is a native of Philadelphia, PA. She earned her B.A. in Biology in 2007 from Bryn Mawr College, an all women's liberal arts school in the greater metro area, and worked for two years at the Academy of Natural Sciences of Philadelphia as a lab manager for the in-house Patrick Center for Environmental Research. Here, she worked with a team of scientists dedicated to water quality monitoring. During this time, she also coordinated the museum's NSF-funded Research Experiences for Undergraduates (REU) Program. As a graduate student, Rosemary was involved as a research mentor and workshop facilitator in the REU program hosted by Blandy Experimental Farm, a University of Virginia research station (and home of the State Arboretum of Virginia) located in the northern Shenandoah Valley of Virginia.
In September 2015, Rosemary started as a postdoctoral scholar in the the lab of Dr. Neal Williams at UC Davis, where she is continuing to research bumblebee ecology. Specifically, she is leading a large field experiment designed to understand how seasonal patterns of food availability affect bumblebee colony foraging dynamics, growth, and reproduction (i.e. demography). This work is being done in collaboration with the lab of Dr. Elizabeth Crone at Tufts University. You can read more about the details of this project here.
Starting in January 2018, Rosemary is joining the lab of Dr. Lynn Adler at the UMass Amherst to carry out research on the influence of diet on bumblebee colony development and health.
When Rosemary isn't busy corralling bees, she enjoys exploring nature with her family. Occasionally, she also enjoys exploring nature with her family while working - the benefit of being a field ecologist! She also spends time raising awareness about 22q11.2 Deletion Syndrome: the second most common chromosomal disorder in humans, affecting between 1:2000 and 1:4000 live births annually.
