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
