Science is a way of thinking.

I am a Ph.D. student in Stanford University's Department of Biology. In the Ecology and Evolution cluster, I work in the Fukami Lab studying priority effects and historical contingency in nectar yeast populations. I am a Stanford Graduate Fellow (2017-2022) and National Science Foundation Graduate Research Fellow (2017-2020). Before coming to Stanford, I completed a concurrent undergraduate/graduate (M.Sc.) degree at the University of Michigan in Molecular, Cellular, & Developmental Biology.

Stanford University Biology Department: Fukami Lab

In the Fukami lab, I research the chemical and genetic mechanisms that may contribute to priority effects exerted by Mimulus aurantiacus nectar microbes. I am interested in using analytical chemistry and molecular biology to investigate these questions. 


During my PhD, I am interested in investigating the influence of immigration on the end states of natural communities. Specifically, I am using a nectar microbe system to investigate the mechanisms yeasts use to exert priority effects in a floral nectar environment. During my undergraduate research, I investigated the role of global change (elevated carbon dioxide) on the chemical ecology and population dynamics of insect herbivores. 


In every ecosystem, there is an invisible web of chemicals that mediate interactions between individuals. I use analytical chemistry to identify and isolate these chemical compounds in order to learn how they influence interactions between individuals, populations, communities, and ecosystems.


Molecular biology provides a helpful set of tools and approaches with which to investigate the mechanisms that may drive changes in community composition. Using two approaches, gene cloning and population genetics, I am interested in investigating how genes influence community structure and function.

University of Michigan Life Sciences Institute: Sherman Lab

During my master's degree, I researched in the lab of Dr. David Sherman (Department of Medicinal Chemistry, Department of Chemistry, Department of Microbiology & Immunology) in collaboration with Dr. Shasha Li. Studying the pharmacological effects of natural products produced by non-model bacteria, I used molecular cloning and analytical chemistry (LC-MS, TOF MS, HPLC, NMR) to elucidate the biosynthetic pathway of hapalindole natural products in the cyanobacteria Fisherella ambigua (UTEX 1806).

University of Michigan Department of Ecology & Evolutionary Biology: Hunter Lab

As an undergraduate at the University of Michigan, I completed my Honors Thesis and a National Science Foundation Research Experience for Undergraduates ( NSF REU) with Dr. Mark Hunter (Department of Ecology & Evolutionary Biology) at the University of Michigan Biological Station. In this research, I investigated the effects of elevated, atmospheric carbon dioxide on plant chemistry, specifically two milkweed species, Asclepias syriaca (common milkweed) and Asclepias speciosa (showy milkweed), and how this changing plant chemistry may mediate plant-herbivore interactions with a specialist herbivore, Aphis nerii (Oleander aphid).
