Research

I am an academic nurse scientist pursuing research at the intersection of physiology and management of labor in women with obesity, a group with the highest cesarean and labor dysfunction rates. My dissertation research at the University of Colorado examined biobehavioral phenomena involved in unplanned cesarean delivery, including higher synthetic oxytocin requirements among otherwise low-risk, obese women in labor (NINR F31 NR014061). I built upon this single-site investigation in my subsequent analysis using the large NICHD Consortium on Safe Labor dataset to demonstrate there was an independent and dose-response relationship between increasing maternal BMI and both unplanned cesarean birth and longer labor duration, regardless of the hospital’s inclusion of nurse-midwifery providers. I work with a multidisciplinary group of scientists who are investigating the biobehavioral mechanisms, including metabolomics variations, of poor delivery outcomes among African-American women. I was awarded a career development award through NIH NINR (K01 NR016984) in 2017 to expand my training by incorporating high-resolution metabolomics methodologies to better understand alterations underlying obesity-associated pregnancy dysfunction. Utilizing a conceptual model of impaired labor endurance in the obese woman, I completed intensive 3-year training in metabolomic/lipidomics techniques and prospective pregnancy cohort recruitment/retention. I recently completed a series of analyses to search for associations in metabolites present in serum from late-pregnancy with labor dysfunction in an African-American cohort. I discovered that metabolomic pathways consistent with lipotoxicity predicted labor dysfunction—even in non-obese women, and changes in the linoleate pathway predicted difficult labor induction. Merging my rich, 12-year clinical experience as a midwife with a systems biology approach, my research is uniquely focused on biopsychosocial mechanisms underpinning poor labor outcomes.
