She graduated from Southern Methodist University 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.
