Ryan Chisholm PhD

 
   
 
 
  Ryan Chisholm  |  I am an assistant professor at the National University of Singapore. I am interested in theoretical approaches to problems in ecology and conservation biology, with a particular focus on patterns of biodiversity, ecosystem function, ecosystem services and alien invasive species. I am also a research associate at the Smithsonian Tropical Research Institute.
