Headshot of Gyanu Lamichhane
  • Associate Professor of Medicine


Dr. Gyanu Lamichhane is an Associate Professor in the Division of Infectious Diseases, Johns Hopkins University School of Medicine. His research focuses on the bacterial cell wall physiology in relevance to diseases in humans. He studies basic mechanisms associated with cell walls, but with an intent to leverage findings to develop tools that will be useful in the clinic. His group devotes significant effort on developing new strategies to treat mycobacterial diseases. Additionally, a new and significant effort of his research is fundamental but understudied mechanisms that lead to antibacterial resistance. more
