Dr. Mona Hanna-Attisha, one of the heroes of the Flint water crisis, has just been named to TIME Magazine's 100 most influential people in the world list.

Dr. Mona Hanna-Attisha, who is director of the Michigan State University and Hurley Children's Hospital Pediatric Public Health Initiative, is widely credited with bringing national attention to the higher lead levels in Flint children after the city switched to the Flint River as a primary water source back in April 2014. She has since appeared on national television and testified in front of Congress about the effects of lead on children.

Dr. Mona captured the 20th spot in the top 100 list alongside U.S. Senator Elizabeth Warren, talk show hosts Stephen Colbert and John Oliver and German Chancellor Angela Merkel.

The full list will appear in the May 2 issue of TIME Magazine which will be available on newsstands this Friday.
