My current research interests include characteristics and biological markers that are related to receiving a diagnosis of endometriosis and to how well patients respond to endometriosis treatments over time. I conduct research mainly within the Women’s Health Study: from Adolescence to Adulthood, which has been following participants with and without endometriosis for over 10 years. I currently have a National Institutes of Health R21 grant to look at nerve growth factors in the fluid within the pelvic cavity and how levels of these nerve growth factors are related to chronic pelvic pain among participants with endometriosis. My goal is to identify a biological marker that can be used to determine which endometriosis patients will continue to have severe pelvic pain even after they have received endometriosis-related treatment. Recently, I have also started to conduct research in health disparities and endometriosis. I’m currently conducting a qualitative, interview-based study to assess how racial and ethnic groups may experience different barriers to reaching an endometriosis diagnosis, which on average takes seven years from the start of symptoms to receiving a diagnosis.
