I am currently conducting two projects for Acadia National Park. In the first project, I am investigating vegetation cover changes along trails, campsites, and road systems to identify if those recreational infrastructures attract more direct vegetation impacts. In the second project, I am emphasizing the utility of remote sensing technology as a way of monitoring visitor-induced impacts and eventually assessing the efficacy of management strategies designed to enhance vegetation recovery at high-use destinations in the park.

My research focuses on using geochemistry to answer geological questions that focus on igneous petrology, ore deposits, and tectonics. Techniques that I use include petrography, bulk rock geochemistry, mineral geochemistry, and microanalyses of fluid inclusions. My largest current project involves looking at alkali-rich igneous rocks called lamprophryes from the end of Appalachian mountain building events in northern New Jersey and southern New York to better understand how they formed and their relationship with other intrusions in the area. My newest project is looking at critical minerals necessary for alternative energies such as gallium, germanium, and others in historic mining districts in New York to better understand whether these deposits or others like them could be reimagined for modern metals, but also how they form from hydrothermal fluids. A third project is aimed at understanding the mantle beneath the continental lithosphere of the East Coast by looking at xenoliths of the mantle rocks brough to the surface by volcanic activity in lamprophyres from Rhode Island. Finally, the last project that I am working on is understanding how iron oxide-apatite ore deposits form and whether these deposits can have rare earth elements needed for alternative energies, electric vehicles, and all modern technologies.

RESEARCH INTERESTS

My research interests span a wide range of issues related to applied wildlife management and population response to habitat and landscape change. I employ a variety of field techniques, spatial analyses, and statistical methods to evaluate wildlife population dynamics, demographic parameters, movement patterns, habitat use, and genetic structure of wildlife populations. I also focus on the human dimension of wildlife management to better understand stakeholder perceptions of wildlife populations and management decisions. Integrating the human dimension into conservation and management decisions is essential for developing effective solutions to these often challenging problems.

My current research interests incorporate many aspects of structural geology, metamorphic petrology, and rock magnetism within the context of field geology. I am interested in understanding the relationships between deformation and metamorphism at a variety of scales from thin sections to crustal exposures. These relationships provide the context for geochronological analyses that can be related to kinematic studies and metamorphic conditions including pressure, temperature, and oxygen fugacity. By determining the conditions of deformation and metamorphism, geophysical data derived from aeromagnetic and gravity surveys can be better interpreted with an understanding of the processes that influence rock properties such as magnetic susceptibility and density. I believe that this approach is instrumental in accurately reconstructing the kinematics, timing and rheology of crustal domains within polydeformed terrains. Ultimately, the information gained from this style of research furthers our understanding of modern tectonic processes and gives us insight to the geologic history of specific locations.
