Callie Chappell

PhD student
E-mail: calliech at stanford dot edu

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.


Jessica Coyle

Lecturer
E-mail: jes.r.coyle at gmail dot com

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.


Nick Hendershot

PhD student
E-mail: jhende at stanford dot edu

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 in his PhD research, he 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 Ke

PhD student
E-mail: pojuke at stanford dot edu

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.


Noam Rosenthal

Master's student

E-mail: nrose at stanford dot edu

Noam is a Master's student interested in higher-order interactions in microbial communities and is currently examining competitive mechanisms in nectar yeast. Noam completed a BSc in Environmental Engineering at Stanford and worked with Matthias Rillig's lab on their "gradual change" project before returning to Stanford. In addition to evolution and ecology, Noam cares a lot about urban design and ways of integrating ecology into city planning.


Priscilla San Juan

PhD student
E-mail: psanjuan at stanford dot edu

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.


Akira and Yutaka Fukami

Honorary 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. Most recently, in summer 2017, Nancy Chang, Jasmine Gilliam, and Ben LeRoy worked 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. See below for former members.
