Danish researcher Poul Thorsen, a former scientist associated with the U.S. Centers for Disease Control and Prevention (CDC), is expected to plead guilty next week to federal charges stemming from an alleged scheme to steal more than $1 million in government research funding, according to prosecutors and recent court developments.
Thorsen, 65, faces charges of wire fraud and money laundering connected to CDC-funded research projects examining autism, vaccine exposure and other childhood and developmental health issues. An assistant U.S. attorney has confirmed that prosecutors are working with Thorsen on a plea agreement, although the precise charges he will admit to and the final terms of the agreement have not been publicly disclosed.
Alleged misuse of CDC grant money
According to the U.S. Department of Justice, the CDC awarded more than $11 million between 2000 and 2009 to two Danish government agencies for research into autism and vaccine exposure, cerebral palsy and infections during pregnancy, and childhood development and fetal alcohol exposure.
Prosecutors allege that Thorsen, who had previously worked as a visiting scientist at the CDC, became responsible for administering research funds in Denmark. Between February 2004 and June 2008, he allegedly submitted more than a dozen fraudulent invoices containing a forged CDC laboratory official’s signature.
The invoices allegedly caused Aarhus University to transfer hundreds of thousands of dollars into accounts that were presented as CDC-related accounts but were actually controlled by Thorsen. Prosecutors say he subsequently used the money for personal expenses, including the purchase of a home in Atlanta, vehicles and a Harley-Davidson motorcycle.
Long-running federal case
Thorsen was indicted by a federal grand jury in Georgia in April 2011. He remained outside U.S. custody for nearly 14 years before being arrested in Passau, Germany, in June 2025 under an INTERPOL Red Notice. Germany later approved his extradition, and he was returned to the United States in May 2026.
Following his extradition, Thorsen was arraigned in federal court in Atlanta and held without bail while the case proceeded. The indictment charges him with two counts of wire fraud and nine counts of money laundering.
Why the case has attracted attention
Thorsen’s research has received renewed attention because he was a co-author of studies that reported no link between childhood vaccination and autism. His legal case has subsequently become a focus of wider debate over vaccine safety and the integrity of publicly funded medical research.
However, the financial fraud allegations and the scientific conclusions of his research are separate issues. The federal case concerns the alleged diversion of grant money through fraudulent invoices; the Justice Department’s allegations do not establish that Thorsen falsified scientific findings or that his research conclusions about vaccines and autism were fraudulent.
Guilty plea could bring long-running case closer to conclusion
The expected plea would mark a major development in a case that began more than 15 years ago. Thorsen’s reported agreement with prosecutors could resolve at least part of the federal government’s long-running effort to hold him accountable for the alleged misuse of public research funds.
The case also highlights the importance of financial oversight for government-funded scientific research. Federal officials have emphasized that grant money allocated for public health research is intended to support scientific work and cannot legally be diverted for personal use.
Thorsen remains in federal custody as proceedings continue. A guilty plea has not yet been entered as of August 25, 2026, and the final terms of any agreement remain subject to court proceedings.
