I am interested in conservation genomics. Specifically, how the genomic health of populations changes across ecosystems.

Introduction
I am a postdoctoral researcher in the Collaborative Conservation Genomics Laboratory at UIUC studying conservation genomics. I am particularly interested in the intersection of species distribution modeling and genomics for imperiled and invasive species. Through my time at UIUC, I have excelled in the use of next-generation sequencing, metabarcoding, and the use of eDNA for conservation actions.

Aim
Freshwater mussels are considered among the most at‐risk taxa in the world. As such, comprehensive monitoring assessments of what abiotic and biotic factors influence mussel occupancy will be vital for guiding effective conservation. Here, we analysed vertebrate and mussel environmental DNA (eDNA) metabarcoding data to explore the influence of...
While previous studies have explored the impact of behavior and life history on environmental DNA (eDNA), little research has been conducted on the impact of molting on eDNA detectability and particle size for aquatic arthropods like crayfish. To address this knowledge gap, we conducted a study examining how molting affects eDNA detectability over...
Fisheries monitoring, management, funding, and public interest have traditionally focused on game fishes, leading to insufficient data for many non-game freshwater fishes—including lampreys. Conserving lampreys is particularly challenging given their unique life history and propensity for avoiding conventional sampling methods. However, species dis...
Researchers, managers, and policymakers have historically neglected non-game fishes relative to game fishes, and this oversight has extended to invasive non-game fishes in the United States. One such fish—the Eastern Banded Killifish (Fundulus diaphanus diaphanus Lesueur 1817)—has established and rapidly spread in Lake Michigan and connected waters...
Sleeper” invaders are non-native populations that experience time-lags post-establishment before subsequent spread or negative impacts, challenging managers to differentiate harmless non-native species from invasive species. In lakes of northern Wisconsin, United States, Rusty Crayfish (Faxonius rusticus Girard, 1852) has dominated as an invasive s...
Hybridisation can be an important driver of evolutionary change, but hybridisation with invasive species can have adverse effects on native biodiversity. While hybridisation has been documented across taxa, there is limited understanding of ecological factors promoting patterns of hybridisation and the spatial distribution of hybrid individuals. We...
Biological invasions can produce severe ecological impacts at both large spatial scales between distantly related species and also smaller spatial scales between conspecifics. We investigated here a potential intraspecific invasion within Lake Michigan and adjacent waters. Banded killifish (Fundulus diaphanus) experienced population increases and s...
Citizen scientists may provide unique opportunities for surveillance and early detection of management-relevant biological invasions. Here, we report results of a classroom citizen science program that detected the first record of the invasive red swamp crayfish Procambarus clarkii (Girard, 1852) from northern Idaho, United States. Secondary school...
Non-native fishes can cause ecological impacts as invasive species, but identifying which non-native species have harmful impacts is critical to prioritizing management and policy responses. Here, we characterized the state of knowledge on the impacts of a possibly overlooked group of invasive species in the United States: non-game native transplan...
Neonicotinoid insecticides are highly water soluble with relatively long half-lives, which allows them to move into and persist in aquatic ecosystems. However, little is known of the impacts of neonicotinoids on non-target vertebrates, especially at sublethal concentrations. We evaluated the effects of the neonicotinoid clothianidin on the behavior...
The freshwater mussel fauna of the United States, while extraordinarily rich, has the highest imperilment rate of any group of organisms. It is important to understand what factors allow riverine freshwater mussels to persist yet, challenging because of their unique life cycle, benthic habitat preferences, and sensitivity to disturbance across spat...
Understanding the spawning patterns and egg production of clownfish is important for understanding their life history and the factors contributing to population persistence. The egg production and temporal spawning patterns of eight breeding pairs of yellowtail clownfish, Amphiprion clarkii (Bennett, 1830), were observed for a 14- mo period on a co...
