Principal Investigator

Dr. Liza S. Comita

Liza is a Professor of Tropical Forest Ecology in the School of the Environment at Yale University, with a secondary appointment in the Department of Ecology & Evolutionary Biology. She is also a Research Associate at the Smithsonian Tropical Research Institute in Panama and co-director of the Yale Center for Natural Carbon Capture. She earned a Bachelor's degree in Biology and Master's degree in Conservation Biology from the University of Pennsylvania and a PhD in Plant Biology from the University of Georgia. She was previously an Assistant Professor in the Department of Evolution, Ecology and Organismal Biology at The Ohio State University and held postdoctoral positions at the University of Minnesota, the Earth Institute at Columbia University, and the National Center for Ecological Analysis and Synthesis (NCEAS).  As a plant community ecologist, Liza is interested in ecological mechanisms driving patterns of diversity, dynamics, and species distributions in both pristine and human-altered tropical forests.

Graduate Students

Harikrishnan Venugopalan Nair Radhamoni

Picture
Hari is a PhD candidate conducting research on how the taxonomic and functional diversity of non-woody (herbaceous) plants vary along gradients of moisture and light in the forests of Western Ghats in India. He has a Bachelor's degree in Agriculture, a Master's degree in Environmental Science, and a diploma in Journalism. Hari previously spent many years working with wildlife conservation projects in the tropics. Currently, he is excited about finding new, efficient methods and protocols to study herbaceous plants and their traits, including field surveys, nursery experiments, and herbarium-based research.

Megan Sullivan

Megan is a PhD candidate. Her dissertation research focuses on the how selective logging alters regeneration and thereby changes the composition, structure, and function of seedling, sapling, and mature tree communities in the tropical rain forests of Gabon. Megan first started working with the Comita Lab as an undergraduate in 2013. Since then she has worked on plant ecology research in Panama, China, Brazil, and Gabon. Read more about Megan's research here.

Akshay Surendra

Akshay is a PhD student who joined the Comita Lab in Fall 2019. For his dissertation research, he plans to focus on the role of plant-soil feedback in promoting species coexistence and driving species distributions across edaphic gradients in tropical forests. He is interested in testing these questions in mixed dipterocarp forests of Sri Lanka. He has previously studied bird community dynamics in forest fragments, forest recovery from repeat selective-logging, and correlates of human-wildlife conflict around protected areas.

Alma Trujillo Miranda

Alma joined the lab as a PhD student in Fall 2021. She received a Masters of Science degree from Instituto de Ecología A. C. in México, where she conducted research on the effectiveness of active versus passive restoration strategies implemented in tropical montane cloud forest.

Postdoctoral Researchers

Dr. Luke Browne

Picture
Luke received his PhD from Tulane University where he focused on patterns of genetic and species diversity of palm tree communities in Ecuador. Following his PhD, he was a postdoctoral researcher at UCLA working on the genomics of climate adaptation in oak trees. Since joining the Comita Lab in 2019, he has been researching the effects of extreme climate events like El Niño on tropical tree communities across multiple sites in Panama.  Read more about Luke's research here.

Dr. Michelle Spicer

Picture
Michelle's research focuses on drivers of temperate and tropical forest community change. Currently, she is studying the assembly and development of epiphyte communities in Panama and in the Pacific Northwest. She is a postdoctoral scholar funded through a National Science Foundation Postdoctoral Research Fellowship in Biology. Michelle got her PhD in the Biological Sciences Department at the University of Pittsburgh.  Her dissertation research focused on two diverse, yet understudied plant communities: the herbaceous understory layer of the temperate deciduous forest in western Pennsylvania, and vascular epiphytes of tropical cloud forests in Santa Fe National Park in Veraguas, Panama. Read more about Michelle here.

Dr. Nohemi Huanca Nunez

Picture
Nohemi is a YIBS Gaylord Donnelley Postdoctoral Associate in the School of the Environment at Yale University. Her overarching research goal is to explain the ecological processes that shape and promote diversity in old-growth forests and influence the regeneration of human-modified landscapes. Currently, at the Comita Lab, Nohemi focuses on the interaction between above-ground and below-ground functionality and the role of root traits in shaping composition in tree communities recovering from human disturbance in Panama. She earned her Ph.D. from the University of Nebraska-Lincoln, focusing on abiotic and biotic factors shaping seed-rain and seedling establishment in human-modified landscapes in Costa Rica.

Dr. Anita Weissflog

Picture
Anita investigates how insect herbivores and fungal pathogens affect seedling dynamics during the natural regeneration of tropical rainforests. Anita has joined the Comita lab as a postdoctoral researcher in fall 2022 after obtaining her PhD at Bangor University, UK. Using a combination of laboratory and field studies in Panama, Anita hopes to advance our understanding of how species interactions contribute to shaping patterns of biodiversity and driving ecosystem recovery.
