I am an ecosystem ecologist who combines empirical and modeling techniques to understand the effects of environmental change on the physiological processes governing the fluxes of carbon, water, and nutrients in forest ecosystems. I received my Ph.D. at West Virginia University working under the direction of Dr. Richard Thomas, and I am currently a postdoctoral scholar working with Dr. Tara Hudiburg at the University of Idaho.
Excited to be starting a postdoc with Dr. Tara Hudiburg and her team at the University of Idaho! I will be diving into issues related to the influence of environmental change and policy on forest biogeochemistry.
February 2021: Happy to share a new publication with Richard Thomas where we showed increased photosynthesis is an overwhelming driver of increasing intrinsic water use efficiency over the last century using carbon and oxygen isotopes in tree rings. Check it out here!
I am excited to announce I have joined Dr. Anna Trugman's lab at the University of California, Santa Barbara as a postdoctoral scholar where I will be using ecological theory and ecosystem modeling to better understand how functional trait assemblages mediate ecosystem vulnerability to climate extremes.
I have successfully defended my dissertation! Stay tuned for the last few chapters of my dissertation which are currently in revision at my favorite journals. Many, many thanks to my good friend and major advisor, Dr. Richard Thomas, for the never ending support and for guiding me through my graduate studies.
I am thrilled and honored to say my 2019 ESA talk was awarded the W.D. and S.M. Billings Award from the Physiological Ecology Section. Dwight Billings was a pioneer in physiological ecology and was also my academic great grandfather. Many thanks to my friend and mentor, Richard Thomas, for the unwavering support.
Had a wonderful week talking science during the ESA's annual meeting in Louisville, Kentucky. Thanks to all of those who attended my talk, "Contrasting trends in growth and intrinsic water use efficiency of four eastern U.S. tree species".
Excited to have had the opportunity to talk about some of our most recent work documenting the drivers of tree growth in the eastern U.S. using a multi-proxy approach at the EGU's annual meeting in Vienna! Check out a brief overview of our soon to be submitted work here.
With the help of the Roland Schlich Early Career Scientist's Travel support and a travel award from the journal Plants, I will be traveling to the European Geosciences Union's annual meeting in Vienna, Austria to present research on the effects of environmental change on the growth and physiology of two broadleaf deciduous tree species in the eastern United States!
ESA Biogeosciences section awarded my paper, Disentangling the effects of acidic air pollution, atmospheric CO2, and climate change on recent growth of red spruce trees in the Central Appalachian Mountains, the Elizabeth Sulzman award for best graduate student publication of the year at ESA 2018 in New Orleans, LA!
Recent press for our new paper in Global Change Biology documenting red spruce forest recovery!

A great write up regarding my Forest-GEO grant!
My grant proposal, "Using dendroisotopes to disentangle processes of forest recovery from decades of acid deposition" has been selected to receive funding from the Smithsonian Center for Tropical Forest Science - Forest Global Earth Observatory Research Grants Program. I am excited to begin work on this!
