Find a Doctor Disclaimer
“Find a Doctor” is operated by Lifespan and includes all physicians who are on the medical staffs of Lifespan-affiliated hospitals, without any charge to them. Selection is based upon your needs and preferences. Search results will first present, in alphabetical order, physicians employed or contracted with Lifespan or its affiliates, followed by an alphabetical listing of physicians who are in Lifespan’s network of affiliated providers. At the end of that initial list, you can access an alphabetical listing of community physicians with privileges at Lifespan hospitals. All physicians in Find a Doctor have the opportunity to have a picture or video posted on the site. Neither the order of physicians, nor the presence or absence of a photo or video, in Find a Doctor is intended to reflect any preference, priority, or recommendation by Lifespan. Find a Doctor search results are also not based on the volume or value of referrals to Lifespan or its affiliates from any listed physician. Users are free to select their physician of choice from among all Lifespan-affiliated medical staff physicians.
Jennifer F. Friedman, MD, MPH, PhD
Director, Center for International Health Research (CIHR), Rhode Island Hospitalhttps://vivo.brown.edu/display/jffriedm
Jennifer Friedman, MD, MPH, PhD is director of the Lifespan Center for International Health Research (CIHR) at Rhode Island Hospital. Dr. Friedman is also a professor of pediatrics and epidemiology at The Warren Alpert Medical School of Brown University, as well as its vice chair for faculty affairs in the department of pediatrics.
Dr. Friedman's research addresses how parasitic diseases, particularly helminth infections, cause morbidity among pregnant women and children. Her work has quantified the impact of schistosomiasis on pediatric undernutrition, anemia, and cognitive impairment, including mechanisms mediating morbidity and optimal interventions to mitigate morbidity. Dr. Friedman's work has also addressed the impact of treatment for parasitic diseases during human pregnancy and addressing barriers to uptake.
Since 1995, she has led population-based studies in Brazil, western Kenya, and the Philippines. She designed and implemented a study of water contact patterns in a cohort of 86 volunteers in an S. mansoni endemic area of Brazil. Direct observation of water contact patterns were compared with self-reported contact.
As a postdoctoral Fulbright fellow in western Kenya, Friedman led a study of the impact of insecticide-treated bednets on malnutrition and body composition in 867 school-age children. In addition, she participated in the design and execution of malaria morbidity surveillance for outcomes in pregnancy and in children under five years of age.
Friedman has also participated in basic science studies of the mechanisms of hepatocyte invasion by malaria sporozoites. Together with Jonathan Kurtis, MD, PhD, she has studied the relationship between pro-inflammatory cytokines and malnutrition in an area of intense perennial transmission of malaria in western Kenya.
Friedman is currently leading a National Institutes of Health (NIH)-funded population-based study in the Philippines examining pro-inflammatory mediators of malnutrition and anemia in S. japonicum. For this project, she has developed and field deployed a culturally adapted questionnaire that allows quantification of socio-economic status. In addition, together with Kurtis, she has developed multiplexed lab assays to support hypotheses involving malnutrition (leptin, albumin) and anemia (ferritin, erythropoietin, soluble transferrin receptor).
Friedman's research addresses how parasitic diseases, particularly malaria and schistosomiasis, cause morbidity for pregnant women and children and have focused on how schistosomiasis causes anemia and undernutrition. Her research has identified anemia of inflammation as a primary cause of schistosomiasis related anemia. In addition, studies suggest that pro-inflammatory cytokines may mediate under-nutrition in the context of S. japonicum, due to their cachexia and anorexia inducing effects.
Friedman's current studies seek to quantify the burden of S. japonicum infection during pregnancy and begin to understand the possible mechanisms, including placental inflammation, maternal anemia of inflammation and maternal cachexialanorexia. A recently completed NIAID-funded, randomized, controlled trial of praziquantel given to pregnant women in Leyte, the Philippines, at 12-16 weeks gestation, will further our understanding of the impact of schistosomiasis on human pregnancy.
