Two decades before the latest Ebola outbreak killed thousands of people and left the international community scrambling, former Army scientist Thomas Geisbert was already at war with the virus. His battlefield was the U.S. Army Medical Research Institute for Infectious Diseases at Fort Detrick, Md., home to an elite biosafety Level 4 lab where the U.S. military studies deadly contagions. Geisbert left USAMRIID in 2009, but his Ebola work continues at UTMB, which was designated an Ebola treatment center after Thomas Eric Duncan died of the disease in October at a hospital in Dallas. The facility in Texas where Geisbert works also houses an elite BSL-4 lab. Geisbert is using a grant from the NIH to do more Ebola research and develop three kinds of treatments. His team is hoping to develop a cocktail of drugs that can more effectively combat the virus. Geisbert has made his mark, but the hope of saving lives with better vaccines and treatments keeps him motivated to do more.
