Callie is interested in using molecular biology and analytical chemistry to explore species traits that contribute to priority effects. To investigate mechanisms that may underlie priority effects, she is planning to focus on Mimulus aurantiacus nectar microbes. Callie completed a concurrent undergraduate/Master's degree from the University of Michigan in 2017. As an undergraduate student, Callie worked with Mark Hunter to study how elevated atmospheric CO2 alters tri-trophic interactions in an Asclepias (milkweed) system via its influence on plant chemical defenses and the population dynamics of a specialist aphid. As a Master's student in Molecular, Cellular, and Developmental Biology, Callie was advised by David Sherman, and studied the biosynthesis of cyanobacterial secondary metabolites using heterologous expression, in vitro enzymatic assays, and analytical chemistry. Callie joined the lab in fall 2017 as a Stanford Graduate Fellow and an NSF Graduate Research Fellow.

Leslie is interested in the influence of plant chemistry on multitrophic interactions under future environmental conditions. Leslie joined the lab in summer 2018 and hopes to study the effects of environmental change on nectar microbial communities and consequent pollinator visitation. Leslie finished her PhD at the University of Michigan with Mark Hunter, where she studied the chemical ecology of the monarch butterfly in the context of environmental change. Her work investigating the influence of elevated CO2 on monarch tolerance and parasite virulence was published in Ecology Letters, summarized in this 3-min video and press release.

Nick is interested in how global change drivers restructure the spatiotemporal dynamics of tropical ecological communities. During his undergraduate studies, Nick used congeneric wood-wren species to look at how interspecific interactions contribute to diversity along elevational gradients in tropical montane forest ecosystems. In 2014, he completed his BSc at the University of Tennessee, Knoxville, under Aimée Classen, where his thesis focused on global drivers of belowground microbial diversity and abundance, published in Ecology. Nick joined the lab in fall 2015, and his PhD research focuses on the long-term consequences of climate and land use change for avian populations and communities in Costa Rica, as well as understanding how interactions within multitrophic communities respond to habitat conversion in Costa Rica and Hawai‘i. When not working, Nick can be found climbing and backpacking throughout California, playing old-time Appalachian and rag-time music, or birding. Nick is a Stanford Graduate Fellow.

Jesse is broadly interested in drivers of lichen and plant community composition, particularly in the context of global change. Recently, a focus of his research has been the effects of shifting wildfire regimes on lichen and plant communities. Jesse uses functional traits and remotely sensed data in combination with field studies to gain insight into mechanisms underpinning ecological processes. He worked as a postdoc at UC Davis after earning his PhD in 2016 with Ellen Damschen at the University of Wisconsin, Madison. He came to Stanford in fall 2018 as a Lecturer. He enjoys involving students in research, and is excited about exploring lichen functional traits and microbes in his teaching and research.

Megan is interested in the capability of microbes, including bacteria and yeasts, to modify environments, and aims to link the genomic potential of microbes with empirical observations to predict the influence of microbial activity on other trophic levels within an ecosystem. Megan joined the lab in fall 2018 and hopes to study the genomic and functional potential of nectar-associated microbes and the effects of their metabolic activity on plant-pollinator interactions. Megan received her PhD in Ecology through a Joint Doctoral Program with San Diego State University and the University of California, Davis. At SDSU, Megan studied with Elizabeth Dinsdale on the microbial ecology of temperate kelp forests, using metagenomics to describe microbial community composition, function, and fluctuations. At UC Davis, Megan worked with Rachel Vannette to study the influence of floral visitation types on microbial community structure and function. Megan is an ARCS Scholar alum.

Priscilla is broadly interested in understanding how animals are impacted by anthropogenic changes in the environment. She is particularly fascinated by the connection between animal microbiome and conservation. She completed her BA in Environmental Science at the University of California, Irvine. As an undergraduate, she researched antibiotic resistance in environmental bacteria, perchlorate toxicology in C. elegans, and the ecological roles of two invasive fish species in Mexico. She worked with Donovan German using digestive enzyme profiles to investigate how the fishes' roles change through a gradient of environments, ranging from pristine to urban conditions. Priscilla joined the lab in summer 2016, and is examining the effects of human land use on avian microbial communities and diversity. She is a Ford Foundation Fellow.

Maggie is interested in microbial community ecology, and the effects that these communities have on their hosts, such as through production of secondary metabolites. She is fascinated by the impacts these organisms have on their chemical environments, and the influences of gradients, such as temperature and pH, on microbial communities. Maggie completed her BS in Cellular and Molecular Biology at California State University, Dominguez Hills, where she worked with Kathryn Theiss and Karin Kram, studying the nectar microbiome of Asclepias curassavica, a non-native tropical milkweed, across the urban heat island gradient of Los Angeles, to explore the connections between temperature, location, and the intricate microbe-plant-pollinator relationships. She also studied the induction of secondary metabolites by Salinispora tropica, a marine obligate actinomycete, through competition with environmental bacteria under Paul Jensen at the Scripps Institution of Oceanography. Maggie joined the lab in summer 2018 as an ADVANCE fellow and an NSF Graduate Research Fellow.

Chih-Fu is interested in combining empirical work and theoretical modeling to understand processes shaping biodiversity, and how the structure and dynamics of ecological communities affect ecosystem functioning. As an undergraduate exchange student at the University of Helsinki, Chih-Fu worked with Janne Soinininen and Jianjun Wang to study the taxonomic scale dependence of elevational patterns in microbial diversity, published in Molecular Ecology. During his Master's studies at National Taiwan University, Chih-Fu worked with Chih-hao Hsieh on the effects of organic matter stoichiometry on marine microbial diversity and functioning. Chih-Fu joined the lab in fall 2019, and wants to study processes shaping microbial community assembly.
