Dr. Nicholas Henshue

Ph.D. candidate (2013-2017); currently Clinical Assistant Professor, University at Buffalo

Dr. Nick Henshue has a B.S. in Environmental Education, Master’s in Biology, and Ph.D. in Ecology. Nick’s research entails earthworms in post-industrial soils — the way they are part of brownfield succession, and how earthworms could be beneficial to restoration ecology. He earned his Ph.D. in 2017 after a first ‘lifetime’ of teaching environmental science


Dr. Anthony Brusa

Ph.D. candidate (2010-2016); currently Postdoctoral Associate, University of Minnesota

Anthony received his PhD in 2016 for work on population genetics of high impact invasive plant species. His work takes a multidisciplinary approach, combining traditional ecology with modern molecular and computational techniques. He is currently a postdoc at the University of Minnesota, where he leads a team developing and verifying genetic markers for detection of


Dr. Megan Litwhiler

Ph.D. candidate (2009-2015); currently Research Communication Associate, Museum of Science, Boston

Megan is fascinated by the unforeseen biodiversity our cities can harbor. Birds are one of the most ubiquitous of the non-human city-dwellers, and one of her very favorite contributors to biodiversity. Coupling her curiosity with urban nature and her penchant for Aves, she focused her dissertation research on an unexpected bird habitat – a polluted


Dr. Kimberly Plank

Ph.D. candidate (2010-2015); currently Biologist, Environmental Protection Agency

Dr. Kimberly Plank’s dissertation research investigated the ecological role of the root enzyme polyphenol oxidase in the invasive plant genus Bromus. She currently is a Biologist in the Technical Support Group at the United States Environmental Protection Agency, where she serves an advisory role for site and project managers to develop and implement remedies and mitigation strategies to


Dr. John Francois

Ph.D. candidate (2006-2014)

Ph.D. thesis “The effect of low level toxicants on growth and fitness of plants – a test of the hormesis effect”.


Dr. Mark June-Wells

Ph.D. candidate (2006-2010)

Ph.D. thesis “Niche divergence: scale and community effects. Implication for community development and invasive species”.


Dr. Linda Rohleder

Ph.D. candidate (2008-2013); currently Director of Land Stewardship, NYNJ Trail Conference

Ph.D. thesis “The vertical dimension of deer browse effects on forest understories: species diversity, plant traits and floristic quality”.


Dr. Julia Perzley

Ph.D. candidate (2010-2018); currently Biology Lecturer, Rutgers-Newark

Dr. Julia Perzley is a plant ecologist interested in urban systems and public science education. Currently she is teaching Concepts in Biology, a large introductory biology course at Rutgers Newark. Julia completed her PhD in the Holzapfel lab in 2018. Her dissertation examined legacy effects of intensive land use by comparing early successional plant communities


Dr. Sahil Wadhwa

Ph.D. candidate (2013-2017); currently Biology Lecturer, Rutgers-Newark

Sahil’s research focused on understanding how heavy metal contamination shapes biodiversity in brownfields. During his PhD, he studied effects of metal contamination on diversity of epigeic invertebrate community and particularly on populations of terrestrial isopods in urban brownfields at Liberty State Park (LSP) in New Jersey, USA. In summer of 2008, he completed his Master’s


Dr. Anthony Cullen

Ph.D. candidate (2014-2018); currently Postdoctoral Associate, Rutgers-Newark (2018-2019)

Tony’s dissertation research explored the dispersal strategies of two invasive viburnum shrubs throughout New Jersey, the New York Metropolitan area, and the greater Philadelphia area. His two motivating questions were as follows: are dispersal strategies employed by closely related species comparable and what strategy leads to greater success at invading communities? To answer these questions, he employed an interdisciplinary approach
