Lab Members


Collin Edwards Collin Edwards
I joined the Crone Lab as a Post Doc in 2019, immediately after earning my PhD from Cornell University. Broadly, I am interested in combining fieldwork with mathematical models and simulations to answer interesting ecological questions, particularly those relating to plant and insect population dynamics. In my free time, I enjoy blacksmithing, archery, martial arts, reading, and amateur photography.

Research Associates

Leone (Lee) Brown Leone (Lee) Brown
Leone (Lee) Brown has returned to the Crone lab where she was previously a postdoc 2013‐2015. She is currently a Research Associate on a DoD SERDP project, Will climate‐mediated phenological shifts affect population viability? A test with butterflies on Department of Defense lands. She is also contributing to a DoD Legacy grant studying population declines in western monarch butterflies. Her interests include population ecology (particularly of birds and butterflies in response to anthropogenic change), movement ecology, landscape ecology, conservation biology, translational ecology, and the intersections of art and science.
Norah Warchola Norah Warchola
I study the ways organisms are affected by heterogeneous landscapes, with a focus on the movement and demography of Lepidoptera. Recently my work has focused on the Fender's blue butterfly (Plebejus icarioides fenderi), an endangered species found in the Willamette Valley of Oregon and the frosted elfin (Callophrys irus) in Massachusetts. In the past, I primarily worked with temperate fruit feeding Nymphalid butterflies, studying their movement in fragmented landscapes and the environmental cues they use to make movement decisions.

Graduate Students

Kirsi Alahuhta Kirsi Alahuhta
I am a graduate student in ecology at the University of Oulu, Finland, and I am working together with Dr. Crone to model the population dynamics of plant species with prolonged dormancy. Since true fate of a plant that does not sprout is unknown (dormant or dead), researchers have been forced to make simplifying assumptions when estimating survival of such plants. I studied, both analytically and empirically, how these assumptions affect the projections of matrix population models for two orchids, Isotria medeoloides and Epipactis atrorubens. In the future I would like to expand my theoretical research to variety of ecological systems.

Brendan Carson Brendan D. Carson, MS
After studying ecology and anthropology at the University of Michigan, Brendan spent several years teaching experiential ecology to middle school students in Texas and California. He earned an MS in entomology at Michigan State University in 2013, and then worked as a Research Associate and Lecturer at Loyola University Chicago. While at LUC, Brendan helped pioneer innovative research in wetland management and restoration in the Great Lakes and provided mentorship to aspiring young environmental scientists. In 2018 he joined the Biology department at Tufts University to earn a PhD studying under Colin Orians and Elizabeth Crone. "There is nothing I enjoy more than sharing my love of the natural world with others, and I feel privileged to be able to spend my life working towards understanding and stewarding life on this planet."
Nick Dorian Nick Dorian
I am a PhD student in the Crone Lab funded by an NSF Graduate Research Fellowship. I am interested in the population ecology of pollinators in the context of a changing environment. Specifically, I study the demographic consequences of climate-induced phenological mismatch for plant-pollinator interactions. I am also an avid naturalist and have previously worked with bumble bees in Massachusetts and California, stingless bees in Costa Rica, songbirds in The Bahamas, and endangered butterflies in Florida and New Hampshire. I graduated with my B.S. in Biology and Environmental Studied from Tufts in 2016.

Sylvie Finn
I am a PhD student in the Crone Lab. My research interests include bee population ecology and pollination biology.
Nathaniel Murphy Nathaniel ("Atticus") Murphy
I am a PhD student in the Crone Lab. I graduated with BSc in Ecology & Evolution from University of Toronto in 2018, where my undergraduate work was first in the community assembly of mutualist microbes living on plant roots and then in the nectar resources available to pollinating bumble bees. I am broadly interested in the evolutionary ecology of mutualisms and their role in maintaining natural populations, especially insect interactions. In the Crone lab, I plan to study the relationship between Puget blue butterflies (Plebejus icarioides blackmoeri) and the ants that protect them in exchange for sugar rewards.
Genevieve Pugesek Genevieve Pugesek
I am a graduate student in the Crone lab. My aspiration is to conduct impactful research and advocate change in conservation strategy. I am broadly interested in community ecology and conservation genetics as they relate to agroecosystems. I am particularly interested in pollinators, as the ecosystem services they provide are significant to both ecological and agricultural systems. After completing my Ph.D. studies, I would like to conduct research centered on the establishment of populations of feral organisms and their impact on ecological communities. Though underappreciated, understanding the impacts of this ongoing change is relevant to conservation of biodiversity.
Eric Scott Eric Scott
I am a Ph.D. candidate in the Biology department at Tufts University with an emphasis on chemical ecology. I’m interested in the mechanisms of plant defense and insect manipulation of plant defenses. My Ph.D. focus is on the effects of climate change and insect herbivory on the quality (flavor and health benefits) of tea (Camellia sinensis). I received my BA in Biology from Whitman College in 2006 and my Masters in Ecology, Evolution, and Conservation Biology from University of Illinois at Urbana-Champaign in 2010. I worked at a tea shop for several years, and since returning to academia have maintained a relationship with the tea industry. I have authored several guest blog posts related to my project on World Of Tea and Tea Geek Blogs.

June Arriens June Arriens
I am a research assistant in the Crone Lab, working with Baltimore checkerspot butterflies. As well as conducting research at our field sites in Maryland, I am also looking at phenological changes in the butterflies and the plants that they use. I graduated from the University of Connecticut in 2016 with a B.S. in Ecology and Evolutionary Biology.
James Michielini James Michielini
I'm currently studying the relationship between phenology and abundance of Massachusetts butterflies in the Crone Lab. We know that different organisms respond differently to anthropogenic changes like global warming and so we're essentially looking at how butterflies are changing their flight timing in response and how that affects their populations. To do this we're using citizen science data to see if butterfly species emerging earlier in the spring and persisting later in the fall are being seen more often.

Lab Manager

Rob Bosso Rob Bosso
My role is to ensure that every aspect of the lab runs efficiently, with a primary focus on sponsored research administration. I am also involved in the management of technological and physical resources. This position combines my experience in university administrative support with my academic background in biology and sustainability. Previously, I was employed at Harvard University.
