Alison Macalady

I am a dendrochronologist and geographer investigating factors that affect tree mortality during droughts of the past century. Climate-induced tre mortality is an emerging global phenomenon that could have wide-ranging consequences for forest composition, structure and function. Warm drought and associated eruptions of bark beetles recently resulted in extensive tree mortality in piñon-juniper woodlands of the southwestern United States.

I am a PhD candidate in Epidemiology with a minor in Global Change. As well as a researcher and project coordinator for the Skin Cancer Institute of the University of Arizona Cancer Center. My research focuses on how global change (both physical and social) influences public health. My current primary research project concentrates on identifying spatial factors, related to geographic and built environments, which are associated with melanoma incidence and skin cancer risk.
