Gilles-Éric Séralini (born 23 August 1960) is a French molecular biologist, political advisor and activist on genetically modified organisms and foods.

Séralini underwent research on corticosteroid-binding globulin, before being appointed a professor at the University of Caen in June 1991, a position he has held ever since.

Séralini founded the Committee of Research and Independent Information on Genetic Engineering (CRIIGEN) with Corine Lepage, a former politician, and Pierre-Henri Gouyon, a professor from the Muséum national d'histoire naturelle, in 1999.

[11][12][13] They concluded that the genetically modified maize used, MON 863, resulted in significant variations to the control rats weight, triglyceride levels and urine composition.

[11] They also concluded it effected the liver, kidney, adrenal glands, heart, and haematopoietic system and recommended that safety experiments continue beyond 90 days.

It asked EU countries for any new data about the strain, new opinions on the original Monsanto study and a technical meeting with the authors of the 2007 CRIIGEN paper.

The EFSA concluded that all blood chemistry and organ weight values fell within the normal range for the control animals in question[15] and that the Séralini paper used incorrect statistical methods.

[25][non-primary source needed] On 19 September 2012, Séralini and his colleagues published a peer-reviewed paper funded by CRIIGIN titled "Long-term toxicity of a Roundup herbicide and a Roundup-tolerant genetically modified maize" in Food and Chemical Toxicology (FCT).

Smith disapproved of the planned inclusion of molecular biologist Kevin Folta and Séralini accused Jon Entine, who organized the debate's panel, of libel.

"[36] Various journalists criticized Séralini's strategy towards the public, since he asked media to sign non-disclosure agreements before the publishing and tried to interdict requests to other scientists.

[3][37][38] A 2016 paper published by Seralini claims homeopathic remedies protect against acute glyphosate intake alleged toxicity.

[50] The related lab received funding from Sevene Pharma to study the detoxifying capacity of their plant extracts on Roundup residues, bisphenol A and atrazine.
