To ensure the accuracy of our patient satisfaction scores, we require that providers who see patients receive
a minimum number of completed patient-submitted surveys before their reviews are listed on their profiles.
Star ratings on this site are collected on a rolling basis from the previous 12 months.
Additionally, some of the physicians listed on our site do not see patients directly, and therefore, do not receive
evaluation and ratings from patients.

Esophageal squamous epithelium exhibits a defined proliferation-differentiation equilibrium that supports barrier function, a primary defense against luminal contents, which may include food allergens and carcinogens. Esophageal pathology often features impaired squamous differentiation and barrier dysfunction, suggesting that mucosal defense mechanisms beyond mechanical barrier exist. We have identified autophagy as a critical cytoprotective mechanism in esophageal epithelia exposed to stressors relevant to esophageal squamous cell carcinoma (ESCC; one of the most deadly forms of human cancer), Eosinophilic Esophagitis (EoE; an emerging food allergy-associated inflammatory disorder) and Barrett’s Esophagus (BE; a precursor to esophageal adenocarcinoma). Using these studies as a foundation, we now aim to define the precise functional roles of autophagy in epithelial mucosal defense under conditions of health and disease. We utilize a multi-disciplinary approach coupling molecular biology and biochemical techniques with innovative murine disease models, 3D organoid culture and patient-derived specimens with associated clinical data to uncover fundamental mechanisms contributing to epithelial homeostasis and then apply this knowledge toward the development of novel translational avenues for prevention, prognosis and therapy in benign and malignant human diseases.
The following ratings and reviews are based on verified feedback collected from independently administered
patient experience surveys. The ratings and comments submitted by patients reflect their own views and opinions.
