Hobbies: I love finding new adventures with my husband and our almost 2-year-old, running, and reading (I’ll read just about anything — from historical fiction to romantasy to a good mystery)
Research/QI interests: I’m passionate about understanding how social factors affect how quickly children with cancer are diagnosed and begin treatment, and I hope to expand this work to underdeveloped countries. I’m also interested in improving how we give vaccines to children after stem cell transplant.
Why pediatric hematology/oncology? I chose hematology/oncology because I love the patients and the science — and because, let’s be real, cancer sucks. This specialty allows me to combine meaningful relationships with families, complex clinical care and opportunities to make a difference through research and quality improvement.

Research/QI interests: I am interested in the intersection of oncology, infectious disease and immunology. My research objectives are focused on identifying risk factors for, decreasing the incidence of, and improving outcomes associated with infectious complications and other immunologic sequelae in pediatric cancer patients.
Why pediatric hematology/oncology? Pediatric hematology/oncology combines everything I love about pediatric medicine — resilient patients, kind and supportive co-workers, opportunities for inpatient and outpatient care, longitudinal relationships with patients and their families, interesting pathophysiology and nearly endless opportunities for research in the field.

Why pediatric hematology/oncology? I chose pediatric hematology/oncology for the longitudinal relationships with families and patients of a variety of ages, the combination of inpatient and outpatient medicine for a spectrum of clinical status (stable to critically ill), and the highly collaborative culture amongst pediatric hematology/oncology docs at pediatric institutions. Additionally, the relationships between physicians and patients/families are embedded in resilience and teamwork.
Why IU School of Medicine and Riley Hospital? The culture at Riley Hospital is really great for trainees. They are used to having fellows and teaching but also comfortable functioning without them if needed. There is a wide array of patient presentations from common to exceedingly rare with encouragement of fellows to be involved.

Additionally the biology is endlessly fascinating and the landscape of care for patients with cancer is constantly evolving, making it exciting and dynamic.

Why Pediatric Hematology/Oncology?
