Dr. Wirtz has spent a distinguished career in researching and developing solutions to mitigate the impact of insect-transmitted diseases, especially by mosquitoes, on the world’s population. In 1997, he began an 18-year career at the CDC, where he directed activities to reduce the threat of arthropod-borne diseases to humans. He also supervised work on insecticide resistance, analysis of insecticides and antimalarial drugs, and evaluation and implementation of long-lasting insecticide treated bed net and indoor residual spray programs. His commitment to vector control spanned the globe and touched many countries and worldwide organizations, including the World Health Organization. Dr. Wirtz is also an accomplished author and co-author, with his work appearing in more than 275 publications, including nine book chapters, on worldwide parasite-related health issues. After retiring from the CDC in 2015, Dr. Wirtz continues to assist at the agency as a volunteer guest researcher and also works as an independent consultant.
