  • Congenital Diaphragmatic Hernia
  • Endoscopy

Research Plan

  • Mentor: Ali Mencin, MD
  • Survivors of congenital diaphragmatic hernia (CDH) suffer from short and long-term gastrointestinal sequelae including reflux, failure to thrive and motility disorders. Our hospital is a referral center for babies pre- and post-natally diagnosed with CDH due to our NICU, ECMO program and surgical expertise. I will be looking at risk factors that predispose CDH survivors to worsening foregut dysfunction in order to achieve a better algorithm and standard of care to better optimize gastrointestinal and nutritional management in this population.

  • Taste Receptor Signaling in the Intestinal Tract

Research Plan

  • Mentor: Charles Zuker, PhD
  • Sarah Taylor is working in the laboratory of Dr. Charles Zuker, PhD investigating the role of taste sensing in the mouse intestine. Much research has elucidated the taste signaling pathway in the tongue and more recently similar taste cells and receptors have been localized to the intestine. Sarah's research will focus on defining this unique population of cells within the mouse intestine and creating knockouts of various taste receptor cells (eg sweet, bitter, umami) in the gut. By subjecting these different knockouts to diets varying in fat content she will explore the hypothesis that mice deficient in taste sensing would have altered hormonal pathways leading to poor satiety and subsequent obesity with its co-morbidities.
