Leslie New
Assistant Professor, Statistics
Dr New graduated from Cornell University (BS in Natural Resources, 2003) and the University of St Andrews (PhD in Statistical Ecology, 2010). She remained at St Andrews as a post-doctoral fellow, before continuing her research with the US Marine Mammal Commission and US Geological Survey.
She is an applied statistician whose research is aimed at addressing questions of ecological interest, often from both an empirical and management perspective. Her work on evaluating the population consequences of disturbance has focused on quantitatively assessing how observed short-term changes in the individual behavior or physiology of marine mammals due to anthropogenic activities may led to long-term impacts on the effected population. In addition, Dr. New has worked to better understand the risk operating wind turbines pose to bird and bat species, and how to estimate and predict the effects wind facilities will have on wildlife populations.
From a statistical perspective, Dr. New’s research has sought to fully incorporate uncertainty into management and conservation decisions and to develop the statistical tools required to analyze the data collected from innovative technology, such devices intended to deter birds and bats from colliding with wind turbines.
Fun Fact: Dr. New volunteers with the 501st Legion, a Star Wars cosplay organization that supports and raises money for charities around the world.
