Former Graduate Students

Alison Hale

Understanding how biotic and abiotic contexts modify the strength of species interactions is a key goal in ecology. Mutualism effectiveness is particularly sensitive to environmental conditions, and the invasion of non-native species is hypothesized to be one biotic factor that can drive mutualism disruption between native species and their partners. Using an ecophysiological approach, Alison tested this mutualism disruption hypothesis using the allelopathic invasive plant, Alliaria petiolata, and examined its impacts on the interaction between arbuscular mycorrhizal fungi (AMF) and Maianthemum racemosum, a common native herb in North America.

Alison is currently a postdoctoral researcher with Dr. Stephen Tonsor at the University of Pittsburgh.

 

April Randle


April's work focused on better understanding the factors that lead to the origin of new species. One major factor central to speciation is the evolution of reproductive isolating barriers. For her dissertation, she simultaneously tested two prominent hypotheses related to the evolution of isolating barriers: The Dobzhansky-Muller (D-M) Model of Speciation and the Reinforcement Model. To test the predictions of these models, she used a comprehensive phylogenetic, biogeographic, and experimental approach to examine the strength of pre- and post-zygotic barriers to reproduction among all species in the genus Collinsia. She also examined how phylogenetic relatedness, divergence time, and current ecological interactions impact the fitness of closely related plant species in sympatry.

April is now conducting post-doctoral research with Dr. Pamela Diggle at the University of Colorado, Boulder.

Former Undergraduate Researchers


 

Katie Abele

I am a senior currently working on a BS degree in Ecology and Evolution, a BA degree in French Language and Literature, and a Chemistry minor. I started working in Dr. Kalisz’s lab earlier last year and so far it’s been great! After graduation I plan on taking some time off to volunteer either with the Peace Corps or Teach for America before continuing on with my education in grad school. In my spare time I like to hike, bike, and travel to new places.

 

Keith Garmire

Keith graduated in 2012 after majoring in Ecology and Evolution. He joined the Kalisz lab in the spring of 2012 and worked on an independent study researching species distribution of Collinsia flowers as a part of his certification in the Geographical Information System (GIS) program. He also worked in the university’s plant growth facilities. After graduation he intends to seek employment in a national or state park to help preserve and understand our nation’s unique ecosystems.

 

 

Brian Keil

I am an Ecology and Evolution major with a minor in chemistry. Currently, I am conducting an independent research project in the Kalisz lab in coordination with the National Aviary. The goal of the project is to determine how the Louisiana Waterthrush can act as a bio indicator for stream quality. I enjoy spending time outside and rock climbing whenever I can. After graduation I plan on finding a job for a couple years then going to grad school to further my education.

Katy Stark

Katy graduated in 2012 with a degree in Biological Sciences and a minor in Chemistry. She began working in the Kalisz lab in the fall of 2011. She is interested in conservation biology, and hopes to work in wildlife research upon graduation.

He then picked up an independent research project studying the effects of deer herbivory on woody species diversity at Trillium Trail. After graduation he plans on starting a career in the field of wildlife management.

 


Sarah Betz

Sarah graduated in 2011 with a Biology degree and was specifically interested in ecology and evolution. She worked in the Kalisz lab in the summer of 2010 collecting data on numerous native and invasive species at Trillium Trail Wildlife Reserve and assisting Alison Hale with her research project throughout the academic year. After graduation she plans to teach high school biology and then go to medical school to become a plastic surgeon.

He started in the Kalisz lab during the summer of 2008 with a project that focused on detecting allelochemicals released into the soil by garlic mustard. We may also eventually characterize an endemic garlic mustard pathogen. I was awarded a Rotary Ambassadorial Scholarship for the 2011-2012 academic year in Brisbane, Queensland in Australia. During my time abroad, I plan to work on a research project at the University of Queensland that aims to determine the mechanism of action of an anti-cancer compound isolated from an Australian plant and its efficacy against several human cancer types. Furthermore, I plan to volunteer with a local cancer council in their community skin cancer awareness and patient care programs. I will also visit Australian Rotary clubs and present about myself and the U.S. Lastly, I will teach woodworking for a few weekends and travel around Australia, Tasmania, and New Zealand during breaks. After all of this, I will begin medical school in August 2012. During my free time, I enjoy bicycling, motorcycling, and turning wood.
