This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Martin Kulldorff rather than just read about it. In short: Martin Kulldorff (born 1962) is a Swedish biostatistician. He was a professor of medicine at Harvard Medical School from 2003 until his dismissal in 2024.

Key takeaways

Martin Kulldorff belongs to astronomy; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Martin Kulldorff to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Martin Kulldorff from memory before moving on to harder problems.

Reference excerpt

Martin Kulldorff (born 1962) is a Swedish biostatistician. He was a professor of medicine at Harvard Medical School from 2003 until his dismissal in 2024. He is a member of the US Food and Drug Administration's Drug Safety and Risk Management Advisory Committee and a former member of the Vaccine Safety Subgroup of the Advisory Committee on Immunization Practices at the Centers for Disease Control and Prevention. In 2020, Kulldorff was a co-author of the Great Barrington Declaration, which advocated lifting COVID-19 restrictions on lower-risk groups to develop herd immunity through infection before vaccines became available, while promoting the fringe notion that vulnerable people could somehow be simultaneously protected from the virus. The declaration was widely rejected, and was criticized as being unethical and infeasible by Tedros Adhanom Ghebreyesus, the director-general of the World Health Organization. Former NIH director Francis S. Collins called him a "fringe epidemiologist". During the pandemic, Kulldorff opposed disease control measures such as vaccination of children, lockdowns, contact tracing, and mask mandates.

Early life and education Kulldorff was born in Lund, Sweden, in 1962, the son of Barbro and Gunnar Kulldorff. He grew up in Umeå and received a BSc in mathematical statistics from Umeå University in 1984. He moved to the United States for his postgraduate studies as a Fulbright fellow, obtaining a Ph.D. in operations research from Cornell University in 1989. His doctoral thesis, titled Optimal Control of Favorable Games with a Time Limit, was written under the direction of David Clay Heath.

Career Kulldorff was an associate professor at the Department of Community Medicine at the University of Connecticut for five years and an associate professor at the Department of Statistics at Uppsala University for six years. He has also worked as a scientist at the National Institutes of Health in the US. From 2003 to 2021 he was a professor of medicine at Harvard Medical School, and from 2015 to 2021 he was also a biostatistician at the Brigham and Women's Hospital. With Farzad Mostashari, Kulldorff developed SaTScan, a free software program used for geographical and hospital disease surveillance which is widely used, as well as a TreeScan software program for data mining. He is the co-developer of the R-Sequential software program for exact sequential analysis. He helped develop and implement statistical methods used by the Vaccine Safety Datalink (VSD) project that the CDC uses, among other tools, to discover and evaluate vaccine health and safety risks. During the COVID-19 pandemic, Kulldorff advised Florida governor Ron DeSantis on health policy. In a September 2020 meeting he advocated aiming for herd immunity by not inhibiting the virus, saying that young people could "live normal life" until it had been reached, at which point older people could live more normal lives too. and co-authored the Great Barrington Declaration. In 2021, Kulldorff was named a senior scientific director at the Brownstone Institute, a right-wing think tank launched by Jeffrey Tucker that publishes articles challenging various measures against COVID-19, presenting research supporting authors' opinions, and discussing alternative measures. Jay Bhattacharya and Sunetra Gupta, his co-authors on the Great Barrington Declaration, also have had roles there. Tucker is the former editorial director of the American Institute for Economic Research (AIER), where the declaration was signed. In December 2021, Kulldorff became one of the first three fellows, along with Bhattacharya and Scott Atlas, at the Academy for Science and Freedom, a program of the private, conservative Hillsdale College, a liberal arts school. In March 2024, Kulldorff announced that Harvard had dismissed him. Kulldorff had refused a COVID vaccination that was required by Mass General Brigham, the hospital through which Harvard employed him as Medical School faculty. In 2025 Kulldorff, along with Jay Bhattacharya and others, founded the Journal of the Academy of Public Health, with Kulldorff serving as one of two editors-in-chief. The journal only publishes work by members of the newly formed "Academy of Public Health,"and is a subsidiary of the Real Clear Foundation, a conservative donor funded organization. The journal has received criticism, with evolutionary biologist Carl Bergstrom describing it as, "dominated [by] a small clique of contrarians around the COVID pandemic," bibliometrics researcher Jens Peter Andersen describing it as "incredibly problematic," and Mallory Harris, a postdoc at the University of Maryland, stating it appears to be a "parallel structure" to facilitate research that wouldn't be accepted in other publications. In June 2025, U.S. secretary of health and human services Robert F. Kennedy Jr. named Kulldorff to the Advisory Committee on Immunization Practices.

Worked examples

Example 1 — a first encounter with Martin Kulldorff

Start with the simplest possible case. Write down what Martin Kulldorff claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Martin Kulldorff before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Martin Kulldorff ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Martin Kulldorff

In research: Martin Kulldorff appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Martin Kulldorff in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Martin Kulldorff is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1962 births, Academic staff of Uppsala University, Biostatisticians, so understanding it makes those chapters shorter.
In everyday life: Look for Martin Kulldorff outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
