The Annual Thomas C. Merigan, Jr., Lecture
Each year, the Division of Infectious Diseases and Geographic Medicine proudly hosts the Thomas C. Merigan, Jr. Lecture, an endowed lectureship honoring Dr. Merigan, Professor Emeritus and former Division Chief. He is a globally recognized virologist whose laboratory developed critical tests for measuring HIV viral load, among many other significant contributions. He has also trained numerous leaders in the field of infectious diseases.
The lectureship invites a distinguished scientist each year to present their research in infectious diseases during our Medicine Grand Rounds. The inaugural lecture in 1994 was delivered by the esteemed Dr. Jonas Salk.
The 29th Merigan Jr. Lecturer
Michael Osterholm, PhD, MPH, Director of Center for Diseases Research and Policy (CIDRAP)
The 2026 Merigan Lecturer
Michael Osterholm, PhD, MPH, is Regents Professor, McKnight Presidential Endowed Chair in Public Health, the director of the Center for Infectious Diseases Research and Policy (CIDRAP), Distinguished Teaching Professor in the Division of Environmental Health Sciences, School of Public Health, a professor in the Technological Leadership Institute, College of Science and Engineering, and an adjunct professor in the Medical School, all at the University of Minnesota.
In early 2025, Dr. Osterholm and colleagues founded the Vaccine Integrity Project, a key initiative dedicated to safeguarding vaccine use in the US. He is also author of the new book, The Big One: How We Must Prepare for Future Deadly Pandemics.
In November 2020, Dr. Osterholm was appointed to President-elect Joe Biden's COVID-19 transition advisory board. From June 2018 through May 2019, he served as a Science Envoy for Health Security on behalf of the US Department of State. He is also on the Luther College Board of Regents.

David L. Heymann is Professor of Infectious Disease Epidemiology, London School of Hygiene and Tropical Medicine; Head of the Centre on Global Health Security at Chatham House, London and Chairman of the Board, Public Health England, UK. Previously he was the World Health Organization's Assistant Director-General for Health Security and Environment, and Representative of the Director-General for polio eradication.
Dr. Sabeti is a computational geneticist with expertise developing algorithms to detect genetic signatures of adaption in humans and the microbial organisms that infect humans. Her lab’s key research areas include: (1) Developing analytical methods to detect and investigate evolution in the genomes of humans and other species (2) Examining host and viral genetic factors driving disease susceptibility to the devastating and deadly diseases in West Africa, Ebola Virus Disease and Lassa hemorrhagic fever. (3) Investigating the genomes of microbes, including Lassa virus, Ebola virus, Plasmodium falciparum malaria, Vibrio cholera, and Mycobacterioum tuberculosis to help in the development of intervention strategies. (4) Determining the microbial cause of undiagnosed acute febrile illness.
Dr. Sabeti completed her undergraduate degree at MIT, her graduate work at Oxford University as a Rhodes Scholar, and her medical degree summa cum laude from Harvard Medical School as a Soros Fellow. Dr. Sabeti is a World Economic Forum (WEF) Young Global Leader and a National Geographic Emerging Explorer, and was named a TIME magazine ‘Person of the Year’ as one of the Ebola fighters. Her awards included the Smithsonian American Ingenuity Award for Natural Science, the Vilcek Prize for Creative Promise, the NIH Innovator Award, the Packard Fellowship, and an Ellis Island Medal of Honor. She has served on the MIT Board of Trustees and the National Academy of Sciences Committee on Women in Science, Medicine, and Engineering. Dr. Sabeti is also the lead singer and co-song writer of the rock band Thousand Days.
Dr. Sabeti is one of the co-founders and a shareholder of SHERLOCK Biosciences, a company dedicated to improving health worldwide through accurate, fast and affordable testing. She is on the board and a shareholder of Danaher Corporation, the parent company of both Cepheid and IDT. She is a scientific advisory board member and shareholder of NextGen Jane, a women's health company launched by two lab alumni.
