Faculty Statement

The primary theme of my clinical research has been improvement in the treatment of patients with sickle cell anemia (SCA). I work with colleagues Dr. Nancy Green on factors that affect response to hydroxyurea in patients with SCA and with Dr. Gary Brittenham on the safety of using valacyclovir, a well-established anti-viral medication, to prevent the red blood cell sickling that causes the complications of SCA. I have led a clinical trial investigating the utility of implementing a clinical pathway for the management of sickle cell pain in the emergency department, and I continue to collaborate currently with Pediatric Emergency Medicine colleagues to further improve our quality of care and explore expanded medication options in the treatment of acute sickle cell pain. We also seek to evaluate this paradigm of care and test its applicability and impact of their use in the medical home model of two city hospitals where I provide pediatric hematology services: Harlem Hospital Center and Lincoln Medical Center.

I have joined the faculty of the Foundations of Clinical Medicine course at Columbia University’s College of Physicians and Surgeons and with a subset of that faculty group I am participating in qualitative research examining the value of including reflective reading and writing in the medical school curriculum. Bringing together several interests, I have also begun to appreciate that the qualitative research methods I am learning in the context of medical education are valuable tools for a project in which I have joined colleagues in the division of Pediatric Pain Medicine in investigating how social media is used by patients with SCA and their advocates.

I am also currently pursuing a Masters of Science in Bioethics, which I hope will enrich and support the clinical and scientific efforts of our division to promote and protect the health of children with sickle cell disease, cancer, and other disorders of the blood.
