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 will join the lab in fall 2017 as a Stanford Graduate Fellow and an NSF Graduate Research Fellow.

Jes is an ecologist who likes to think about processes driving variation in communities from large to small spatial scales. She completed her PhD in 2016 with Allen Hurlbert at UNC-Chapel Hill, where her dissertation research evaluated how morphological and functional traits can be used to detect environmental constraints on lichen epiphyte communities at different spatial scales. Currently, she is working on a model exploring the implications of mutualism on biodiversity patterns in the context of environmental constraints. Jes came to Stanford in September 2016 as a Lecturer to teach research-based undergraduate courses. For additional info on her projects and data sets, see her web site and GitHub.

Manpreet is interested in species interactions and how these networks drive evolutionary outcomes. She completed her PhD in 2012 at the University of Auckland in New Zealand, with Mike Taylor and Jacqueline Beggs. Her PhD research focussed on the previously undiscovered intracellular symbionts of scale insects. She studied the host-symbiont coevolution and traced the ecological significance of this relationship. She received her BSc (Honours) in 2009 and BSc in 2008, also from the University of Auckland. Before moving to Stanford, she worked as a research scientist at the Plant Health and Environment Laboratory of New Zealand, where she developed molecular diagnostics for the identification of some of the world's worst invasive species. In May 2014, Manpreet joined the lab as a postdoctoral fellow to study the community dynamics of Mimulus aurantiacus nectar microbes.

Nick is interested in how ecological communities respond to land use change. 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 Aimee 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 for his PhD thesis, he initiated a project that asks how deforestation and agricultural intensification impact resource use and predator-prey interactions in bird communities in Costa Rica. Nick is a Stanford Graduate Fellow.

Po-Ju is interested in understanding how plant-soil interactions influence plant and microbial community dynamics. He finished his Master's degree at National Taiwan University in 2013 with a focus on theoretical ecology. Supervised by Takeshi Miki and Tzung-Su Ding, his thesis took a trait-based approach to predicting plant-soil feedback strength, later published in New Phytologist. Po-Ju joined the lab in fall 2014, and for his PhD study, he uses 20 years of high-resolution aerial photos taken at Bodega Bay to study the temporal development of plant-soil feedback in dunes. By combining the aerial photo analysis with field work, high-throughput sequencing, greenhouse experiments, and mathematical modelling, he seeks to link microbial succession patterns to vegetation turnover. He is also working on incoporating mechanistic plant-soil feedback models into general coexistence theories to understand plant species coexistence. Po-Ju is a Volttera Award winner.

Andrew's research aims to bridge outstanding gaps between theory and empiricism in understanding the role of environmental variability in generating and maintaining biological diversity. He completed his PhD in 2015 with David Keith at the University of New South Wales in Australia, where he investigated the role of spatio-temporal environmental heterogeneity in maintaining species coexistence and diversity in plant communities in South-east Australia. Previously he received a Masters of Environmental Science and Law from the University of Sydney, and a BSc (Hons) in Ecology from the University of Cape Town, South Africa. Andrew joined the lab as a CEHG postdoctoral fellow in fall 2015. He is investigating the impact of variability in resources (amino acids) and non-resource factors (osmotic pressure and temperature) on species and genotypic coexistence in nectar microbial communities.

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 has started to examine the effects of human land use on avian microbial communities and diversity.

Kaoru is interested in flower-mediated species interactions. She completed her PhD in 2012 at Kyoto University, with Teiji Sota. Her doctoral research focused on the flower gender difference in defense against florivory and the adaptation of florivorous moths against the defense. Since then, she has worked as a research scientist to continue to study flower-florivore-pollinator interactions using chemical analyses. Kaoru joined the lab as a visiting postdoctoral fellow from Kyoto University in April 2017, to work on Mimulus aurantiacus nectar microbes until October 2017. Her previous work with us has been published in AoB PLANTS.
Akira and Yutaka FukamiHonorary members

Akira joined the lab as an honorary member when he was born in January 2012. Akira recruited his brother, Yutaka, into the lab when he was born in December 2014.
In addition, we often have undergraduate students in our lab, either doing their thesis projects or assisting others to gain research experience. In summer 2017, Nancy Chang, Jasmine Gilliam, and Ben LeRoy are working with us on nectar microbes and dune plants, funded by Stanford VPUE and NSF REU.
Our lab also hosts visiting students and scholars from other institutions. Most recently, we had Hirokazu Toju, an Assistant Professor from Kyoto University, as a visiting scholar from September 2015 to February 2016. Among other things, he helped to modernize our capacity and protocol for high-throughout sequencing and analysis.
