Rachel Vannette, Assistant Professor 2015-present
Postdoc, Stanford University, Department of Biology
Ph.D., University of Michigan, Ann Arbor, Department of Ecology and Evolutionary Biology, 2011
Bachelor’s degree, Calvin College, 2006
Amber Crowley-Gall, Postdoctoral researcher 2019-current
Amber is a chemical ecologist with an interest in understanding the role of sensory systems in insect host choice. Her PhD dissertation focused on examining how variation in the olfactory system contributes to host specialization in cactophilic Drosophila. She is currently interested in exploring the role of microbes in insect host selection. She is particularly interested in understanding how plant-microbe interactions, especially plant pathogens, can alter the chemical signatures that insects are exposed to, as well as how these interactions can influence host choice and the impacts of time and environmental conditions. As a member of the Vannette lab she hopes to examine microbe-pollinator interactions, with a focus on plant pathogens and their potential microbial antagonists.

Allie is interested in understanding how microbial community composition and functions contribute to plant phenotypes. She finished her undergraduate degree in Biology at Howard University where her honor’s research focused on the role of nickel as a defense against herbivory. While studying at Texas A&M, Allie focused on microbial community dynamics in hydrocarbon-contaminated soil as a function of plant root exudation and earned a MS in Soil Science. Her current PhD work focuses on understanding how plant growth promoting bacteria contribute to the survival of California wildflowers on serpentine and non-serpentine soil.

Megan Christensen, PhD Student in the Microbiology Graduate Group
Meg is an evolutionary biologist turned microbiologist, broadly interested in microbial interactions/symbioses with plant-pollinator systems, weird evolutionary traits, and crosswords. She obtained her BS from University of Wisconsin-Madison in Evolutionary Biology, where she did research on reducing ecological impacts of phosphorus runoff, ethnobotany and domestication traits in B. rapa, botanical field excursions of all kinds, and the evolution of chemical sets in the early origins of life. In the Vannette lab, she is currently studying Acinetobacter and other nectar microbes and their potential influences on pollen for nutrient procurement.

Rachel is interested in researching how the bacteria in the residential gut microbiome of hummingbirds differ based on their host’s location, species, sex, and age. Rachel completed her undergraduate degree in 2014 with a B.S. in zoology and biological anthropology. As a member of the Vannette lab, she is studying the gut microbiomes of Anna’s hummingbirds.
Ivan graduated from UC Davis in 2018 with a B.S. in Biochemistry and a strong passion for ecology. He is interested in the microbial communities and chemical compositions of flower nectars, and how they are altered by pollinators. Ivan works with Epilobium canum, the California fuchsia, as a model species.
Undergraduates in the lab
Honey Pathak is a senior undergraduate majoring in global disease biology. She is passionate about learning diseases in general and various aspect of it that affect plants, animals and humans. For last few months, as a member of the Vannette lab, Honey got a great opportunity to be part in one of the research projects and learn to identify effective microbial biologics for sustainable biocontrol of fire blight caused by Erwinia amylovora led by Dr. Robert Schaeffer. For future, she aspires to use the skills she gained by working in the lab and the knowledge she is gaining through her GDB major, in pursuing Higher education and make use of her curious nature to explore the wide array of disciplines that can be used in the real world.
Isabelle Maalouf is a biological sciences major. She has a strong interest in the convergence of ecology and evolution, and hopes to pursue a related graduate degree. She loves plants and aquatic life, and her hobbies include theatre and cooking.
Madeline (Maddie) Handy is an undergraduate majoring in Microbiology. She joined the Vannette Lab as part of the Research Scholars Program in Insect Biology. Maddie has a strong interest in how gut microbiota influence host health. In the future, she hopes to be able to apply her research skills and knowledge into the relationship between microorganisms and human systems.
