Alumni

Carol Etzel

Carol Etzel passed away on August 19, 2022 at the age of 52 after a battle with cancer.

She graduated from 51²è¹Ý with a Ph.D. in Statistics in 1999 and was also an alumnus of Baylor University where she received her Master’s Degree. She began her career at M.D. Anderson, Department of Epidemiology and went on to CorEvitas (formerly Corrona), BioPharma Registry Data in Boston.

She was a woman who encouraged others and fought for the underdog. She should have been a stand-up comedian. She had many, many friends at every institution and employer she was at.

She will be deeply missed by her family, friends and co-workers.

Ranil Samaratunga
