My research interests are diverse but focused. I have a firm interest in bone tumors and a soft spot for soft tissue sarcomas, including understanding the underlying pathophysiology and translational work in the clinical pathology lab setting. I joined the 2019-2021 cohort within the Children’s Oncology Group Young Investigator Program with a focus in the bone tumor group. I also am interested in exploring cell signaling and cell-to-cell communication through conventional molecular and proteomic analysis with fellow investigators. My second area of research interest is in gastrointestinal pathology, particularly eosinophilic esophagitis (EoE). Through these EoE projects, I enjoyed expanding my experience in immunology which builds on an interest during my fellowship at Lurie Children’s Hospital of Chicago, which explored transplant immunology and the effect on the gastrointestinal tract. I also enjoy expanding my experience in the area of transplant immunology. My last primary area of interest is in developmental pathology, which often stems from identifying common pathologic findings in the interesting cases I encounter at BC Children’s and Women’s Hospital. I have an interest in leadership and administration, which blossomed during my time as Cohort 2 in the BC Patient Safety and Quality Council’s Clinician Quality Academy.
