Dr. Timothy Amukele is an Associate professor in the Department of Pathology at the Johns Hopkins School of Medicine. His expertise is in clinical laboratories in developing countries. He pioneered several innovations including, the use of medical drones in hard-to-reach places and the List of Essential Diagnostics, which has been adopted by the WHO.

Dr. Amukele is the chief of Pathology and the Director of Clinical Laboratories at Johns Hopkins Bayview Medical Center, as well as the President of Pathologist’s Overseas Inc., a US-based non-profit organization dedicated to developing sustainable histopathology and laboratory medicine services in low- and middle-income countries. 

Dr. Amukele earned his MD and PhD from the Albert Einstein College of Medicine of Yeshiva University and completed his residency in Clinical Pathology at the University of Washington in Seattle, Washington. He is a diplomate of the American Board of Pathology. more

Research Summary

Dr. Amukele’s scholarly work is focused on the diagnostic clinical laboratory systems in low and middle-income countries (LMICs), and in sub-Saharan Africa (SSA) in particular. For this work, he has pioneered three innovations.

  1. Surveyed SSA laboratories by designing a snowball sampling method to identify hard-to-find diagnostic clinical laboratories in LMICs. This resulted in the first comprehensive survey of clinical laboratories in an SSA city as well as a second one for the continent. His approach for comprehensive surveys of clinical laboratories in low-resourced settings has been adopted widely and is being rolled out as a Gates Foundation-funded initiative in several African countries, in collaboration with the African Society for Laboratory Medicine.
  2. Proposed and published a list of Essential Diagnostic Tests (similar to the WHO list of essential medicines) to help guide countries and other large funders investing in clinical laboratories.  In March 2017 the WHO Expert Committee on Selection and Use of Medicines announced their intent to develop an Essential Diagnostics List based on this work.
  3. Pioneered the use of medical drones to transport clinical laboratory samples in places that are geographically challenged.
