Faculty & Staff
Mindy Morales-Williams, PhD
Associate Professor, Rubenstein School
Interim Director, Rubenstein Ecosystem Science Laboratory
ana.morales@uvm.edu
I'm a limnologist specializing in phycology and biogeochemistry. My research interests include phytoplankton community ecology, cyanobacteria bloom dynamics, land-water linkages, and effects of eutrophication on carbon cycling in lake ecosystems. I investigate how fine scale physiological and ecological mechanisms feedback to drive ecosystem and landscape scale processes.
Anila P. Ajayan, PhD
Postdoctoral Researcher, Rubenstein School
anila.ajayan@uvm.edu
I graduated from the University of Kerala from the Department of Botany, India. I am interested in learning trait-based phytoplankton community ecology. I am more interested in understanding: 1) How does trait diversity mediate the effect of anthropogenic/ climatic stressors on ecosystem function? 2) What is the effect of phenotypic plasticity on ecosystem function? 3)How do traits interact between the trophic levels? At UVM, I will be interested in understanding the phytoplankton phenology in response to warming winter conditions in experimental mesocosms and small lakes.
Personally, I am a cheerful, optimistic, and eco-friendly person. Interested in freshwater biomonitoring and biodiversity conservation.
