Emily Kraus

Assistant Extension Scientist

(352) 392-4722


Dr. Emily Kraus began her higher education in Entomology at Purdue University. There, she focused on both biological control and medical entomology. She continued to her M.S. at Kansas State University maintaining her studies on mosquito-transmitted disease. She then served in the U.S. Peace Corps in Senegal, West Africa. Upon her return, she resumed her studies by working in integrated pest management in rice production at Louisiana State University. She did her postdoctoral fellowship at Rhodes University in South Africa where she again studied biological control. This experience set her up nicely for a position with FDACS as a Biological Scientist and subsequently her current role as a UF Extension Scientist for pesticide knowledge and safety at the Pesticide Information Office (PIO).
