Your Expert:
Dr. David N. Appel – Dr. Appel is a professor in the Department of Plant Pathology and Microbiology (PLPM) at Texas A&M University. Since coming to Texas A&M in 1981, his research program has focused on the epidemiology, diagnosis, and control of forest and shade trees, with an emphasis on the devastating oak wilt epidemic in Central Texas. Dr. Appel has more recently been studying the biology and control of wine grape diseases, and is involved with statewide surveys for sudden oak death and citrus greening. He has taught several graduate and undergraduate courses during his career and served in many administrative posts.
