*Check back later to learn about my recent project investigating how the spatial patterning of larval habitats influences egg-laying behavior in Aedes mosquitoes, which can act as vectors human diseases such as West Nile, Zika, and dengue fever.
Toxic microalgae in coral reefs and their seaweed hosts

For this project I am investigating how macroalgal (seaweed) biomass and species composition in coral reefs influence densities of toxic microalgae, focusing particularly on several species of dinoflagellates that cause ciguatera poisoning in people. (More here.)
Ocean Acidification & Coral Reefs
For my master's research I studied how physiological processes like photosynthesis, respiration, and calcification influence one another in calcifying coral reef organisms, and how environmental factors like light, temperature, and pCO2 modulate these relationships. The goal of this research is to provide insights as to how coral reef calcifiers will be influenced by ocean acidification and climate change in the future, including how their distributions may shift across depth zones and light environments.

Fishing Pressure Effects on Coral Reef Benthic Communities
As a research assistant at NCEAS, I assisted with this project characterizing benthic (seafloor) community composition at Kiritimati Atoll over time. This research sought to assess the influence of fishing pressure and environmental variables like oceanographic productivity on reef community structure. (More here.)
Effects of Artisanal Fisheries on Coral Reef Community Structure & Function
As a research technician at Stanford I assisted with this research investigating 1.) how the terrestrial and coral reef systems are linked to each other via nutrient and energy subsidies, 2.) which organisms play an important role shaping both ecosystems, and 3.) how humans change how coral reef food webs are structured.
Importance of Marine Nutrients in Tropical Island Terrestrial Communities
Starting as an undergraduate and then later as a research technician, I conducted research focusing on the effects of marine nutrient subsidies from seabirds on island ecosystems. Part of that work involved determining the role that coconut palm trees play in shaping terrestrial communities by reducing seabird densities, and consequently reducing their nutrient inputs to these systems.
