Research and Professional Interests

Dr. Brush's research focuses on biological and physical processes and their control of species distribution, the response of the terrestrial and aquatic ecosystem to climatic and human disturbances, using the fossil record of organisms and sediments, and atomospheric-biologic interactions in pollen dispersal.
