Kathleen Seidel is an independent researcher and writer, and a sometime librarian, nonprofit staffer, web developer, bookseller, and proprietor of the website Neurodiversity.com (now archived at Neurodiversity.net). Her Neurodiversity Weblog featured essays on autism advocacy, disabling language, autism science, speculative autism treatments, and ethics in human subjects research; the series Significant Misrepresentations was the first in-depth exploration of Mark and David Geier’s “Lupron Protocol,” and Vaccine Court Chronicles discussed vaccine injury litigation and the attorneys and “experts” who promote marginally-supported hypotheses of disability causation. Kathleen is also author of the chapter, Neurodiversity.com: A Decade of Advocacy (in Autistic Community and the Neurodiversity Movement, Springer Nature, 2020), and co-author of A Worldwide Survey of Encryption Products (Berkman Klein Center for Internet & Society, 2016). Her work was the subject of Brian Deer’s article, What Makes an Expert? (BMJ, March 31, 2007), and a chapter in Paul Offit's book, Autism's False Prophets (Columbia University Press, 2008). She is mother to two adults, and lives with her husband of 44 years in Peterborough, New Hampshire.
