Introduction
I'm a plant ecologist with interest in plant community dynamics and functional trait diversity. My previous research focused on coastal plant community response to natural and anthropogenic disturbance. I served as a Visiting Assistant Professor at Minnesota State University, Mankato for the 2021-2022 academic year. My teaching responsibilities included introductory biology courses, MN taxonomy, and Plant Ecology. I am currently a PNNL post-doc at the Joint Global Research Institute (JGCRI).

Article
Full-text available
Sand dunes are important geomorphic formations of coastal ecosystems that are critical in protecting human populations that live in coastal areas. Dune formation is driven by ecomorphodynamic interactions between vegetation and sediment deposition. While there has been extensive research on responses of dune grasses to sand burial, there is a knowl...
Article
Full-text available
Previous work on the US Atlantic coast has generally shown that coastal foredunes are dominated by two dune grass species, Ammophila breviligulata (American beachgrass) and Uniola paniculata (sea oats). From Virginia northward, A. breviligulata dominates, while U. paniculata is the dominant grass south of Virginia. Previous work suggests that these...

Coastal systems experience frequent disturbance and multiple environmental stressors over short spatial and temporal scales. Investigating functional traits in coastal systems has the potential to inform how variation in disturbance frequency and environmental variables influence differences in trait‐based community composition and ecosystem functi...
Article
Full-text available
Despite recent advances, we still do not understand how chronic nutrient enrichment impacts coastal plant community structure and function. We aimed to clarify such impacts by testing for differences in ecosystem productivity and multiple community metrics in response to fertilization. We established plots in 2015 consisting of control (C), nitroge...

Nutrient enrichment alters plant community structure and function at a global scale. Coastal plant systems are expected to experience increased rates of nitrogen and phosphorus deposition by 2100, caused mostly by anthropogenic activity. Despite high density of studies investigating connections between plant community structure and ecosystem functi...
Article
Full-text available
When topography is incorporated into models of barrier dune dynamical states, how it is represented determines the dynamical properties inferred. Bottom-up representations rely on elevation and localized biogeomorphic modification. Top-down representations incorporate constraints imposed by the spatial patterns of topography. These spatial patterns...

Aims: Dune building processes are affected by interactions between the growth of ecosystem engineering dune grasses and environmental factors associated with disturbance such as sand burial and sea-spray. Research investigating how species interactions influence dune community structure and functional trait responses in high abiotic stress environm...
Poster
This poster demonstrates the methods and results of my REU project, wherein belowground biomass was analyzed from a number of plots across a communities and multidimensional gradients. This work was part of Joseph Brown's work as a Ph.D candidate.
