Dr. Greene developed a passion for Epidemiology while earning her Master of Public Health at UCLA. After spending the first 20 years of professional life as a high-risk obstetrics and gynecology research sonographer, she found that the discipline of Epidemiology would allow her to begin answering some of the many challenging questions that had arisen in her chosen field of maternal and child health and to supply the analytic tools needed to search for the answers in valid and reproducible ways.
