My research focuses on population genetics of fungal plant pathogens, population biology, forest health, forest pathology, and diversity and conservation efforts of native plants. Increases in both native and introduced pathogens as a result of climate change have provided numerous opportunities in basic and applied research. My program’s main goal is to utilize novel genetic and genomic tools to integrate molecular data into pragmatic management decisions and provide solutions for preservation of biodiversity, conservation of native species and overall tree improvement programs.
My primary research centers on understanding host-pathogen-vector interactions with a focus on Thousand Cankers Disease (TCD) complex. The fungus, Geosmithia morbida, vectored by the walnut twig beetle, Pityophthorus juglandis, has been associated with disease outbreaks in walnut trees, Juglans spp., known as TCD. Read More
Conservation Genetics and Biodiversity
An additional component of my research program focuses on conservation efforts of native trees, preservation of biodiversity in North American forests, and overall forest and tree health and protection on a global scale. We intend to devote research and teaching efforts to limit the impact of forest diseases and provide an understanding of the evolutionary dynamics, diversity and disease ecology of environmentally, socially and economically, significant trees.

In my lab, we have a number of projects related to population biology/genetics of native and/or economically important plants, as well their pathogens. We are interested in a number of different factors including, but not limited to, understanding the basic biology of the host-pathogen interactions, host-pathogen coevolution, how spatial distribution influences genetic diversity, their population structure and patterns of gene flow. Using these tools can expand our understanding of the ecological and evolutionary dynamics and elucidate historical processes that are a result of the past or current disease outbreak(s).
“Tell me and I forget. Teach me and I remember. Involve me and I learn.” The best way to share your passion is to teach and educate others. That is why I am involved in STEM outreach for both high school and college students. An undergraduate research opportunity I was given as a student was the sole reason I continued my scientific exploration through further education. As a result, I became the person I am today – someone who loves science and loves sharing that passion, enthusiasm and inspiration with students, through both research and teaching. I am a firm believer that the best way to learn is to teach and that one’s education is never ending.
I strongly believe that a teacher is a role model, advisor, guide, inspiration, and someone who is fundamentally involved and entirely dedicated to their student’s success. A teacher leads by example, motivates and encourages students to be the best they can be, and to go beyond their limits and even their own expectations. I feel fortunate and humble that I am able to do a job where I can share my passion and enthusiasm while fostering the educational growth of students. Teaching is an incredible gift, but also an enormous responsibility. As a teacher and researcher, I would like to have the same impact on students that my teachers and role models have had on me. I would like to be the change and inspiration to improve the world we live in by supporting future generations of environmental stewards and scientists.
