Dr. Lowenthal's work is focused on addressing health priorities for children in resource-limited settings. In addition to research projects she serves as research director for the Children's Hospital of Philadelphia Global Health Center, supporting junior researchers (and senior researchers newly working in international settings) to develop projects addressing other health priorities for children in resource-limited settings.
Dr. Lowenthal has a diverse portfolio of research, united by her drive to improve the health of children, particularly those in resource-limited settings. Her research career grew out of full-time clinical work in Botswana prior to coming to CHOP and University of Pennsylvania for research training. She is currently the principal investigator for a Botswana-based study focused on measurement of cognitive function in HIV-affected children and adolescents. Her team is testing the hypothesis that the Penn Computerized Neurocognitive Battery can be culturally adapted as a valid tool for use in youth affected by HIV in resource-limited settings with high HIV prevalence.
Her second study, a collaboration with scientists at the Monell Chemical Senses Research Center, grew out of her observation that dramatic variability in the taste acceptance of a pediatric HIV treatment drug seemed to drive early treatment outcomes. Her team found that differences in taste receptor genetics explain a high proportion of the variability in medication tolerance, paving the way for the R01-funded study to assess the relationship between taste receptor genetics, taste perception, medication adherence, and side effects related to a variety of bitter-tasting pediatric medications.
In addition, Dr. Lowenthal serves as the principal investigator for two philanthropically-funded trials based in the Dominican Republic that aim to evaluate a novel strategy to address iron-deficiency anemia in infants and young children.
Her notable research achievements to date include:
- Research publications/findings cited in and influenced changes to U.S. and international HIV treatment guidelines
- Work with international pediatric partners and CHOP/Penn collaborators to develop evidence-based approaches to improve local pediatric care and improve research capacity at partner sites
- Honored as one of two inaugural winners of the Carole Marcus Mid-Career Award to Promote Career Development and Mentoring in Pediatric Research at CHOP
