Biography
I am dedicated to decreasing the risk of cardiovascular diseases in women through a program of research focusing on sex and/or gender differences in clinical characteristics of cardiovascular diseases, including female-specific characteristics. My research aims to develop evidence showing that women’s cardiovascular health is uniquely different than men’s and this should be addressed at the individual, clinical, and systemic level. I use quantitative, qualitative, and mixed methods in my research collaborations to elucidate sex differences in heart health.
My doctoral work focused on sex-differences in symptoms in adults with heart failure, including strategies to collect reproductive system data from research participants. The focus of one of my career development awards (8K12AR084221) was to examine gender differences in symptoms and healthcare utilization in the year leading up to a new diagnosis of heart failure. The focus of my second career development award (K01H2177176-01A1) is to leverage informatics to improve cardiovascular risk prediction in females. Together, these studies are helping me build a program of research that considers health history, symptom presentation, patient experiences, and healthcare informatics to improve the way we assess and act of cardiovascular risk.
Outside of work I am an avid hiker, and love exploring the Portland food scene.
