Assistant Professor-Clinical, Hematology
Preceptor: Internal Medicine Clinc- 4 hrs. 1/18/11Resident morning report preceptor- 1/12/11 & 11/17/10
During my final year of hematology and oncology fellowship training at the University of Rochester I was selected to participate in an intensive week long program sponsored by the American Society of Hematology (ASH) to learn clinical trial design. ASH is the world's largest professional society serving clinicians and researchers around the world who care for patients with hematologic disorders. It was here that I met Dr. John Byrd and was recruited to join the division of hematology at OSU in 2008 as an assistant professor on the tenure track. My interest then and now is in the development of novel therapeutic agents for patients with myeloid malignancies, both acute myeloid leukemia (AML) and myelodysplastic syndromes (MDS). Currently my assigned clinical effort has been set at 35%.
I approached joining the faculty and beginning a successful career with three goals in mind. First, I planned to learn and then fine tune the skills necessary to build a strong foundation in clinical research. I was able to do that initially with support provided by the K12 CURE supplement, which then allowed me to successfully compete for a career development award sponsored by ASH and the Robert Wood Johnson Foundation. My research has studied the use of novel agents that target aberrant signaling pathways in AML in the context of phase I clinical trials, and most recently has included determining a safe and tolerable dose that is also biologically effective, an innovative trial design. Overall I have led 5 investigator initiated studies, and been a principal investigator or co-investigator on more than 30 studies. This work has resulted in more than twenty peer reviewed articles. I have also continued to pursue excellence in the care that I provide to patients and this has been recognized by patient satisfaction scores and awards.
While initially my career was progressing along the tenure track, securing career development awards, it became clear that my interest in clinical research and education were more consistent with my longer term goals and I transitioned to the clinical track from the tenure track in March of 2014. This allowed me to pursue more fully my second goal, serving as a mentor for students, residents, and fellows. In recognition of my commitment, I was asked to become the associate program director for the Hematology and Oncology fellowship program, a role that I have transitioned into without difficulty and led three impactful curriculum changes.
I have taken on leadership roles within the cancer center as an executive member of the Clinical Science Review Committee and in the college as an alternate member of the College of Medicine Faculty Council. In support of furthering my leadership development I was selected to participate in the year long faculty leadership institute offered by FAME and completed this training in March of this year. Our project received the greatest number of votes and was selected as the winning project. To further my professional development I also enrolled and completed courses requirements for a Master of Public Health in May 2015.
Nationally, I am a member of the ASH Committee on Promoting Diversity and have served as an abstract reviewer, coordinating abstract reviewer, and oral session moderator at our annual meeting. I was also the scientific co-chair for the AML, MDS and Transplantation session at the American Society of Clinical Oncology (ASCO) annual meeting in 2012. ASCO is a professional oncology society dedicated to clinical oncology. Internationally, I successfully applied to establish OSU as a Center of Excellence by the international MDS Foundation and serve as the point of contact for the Foundation.
In summary, I have built a solid foundation and have had numerous achievements that are sure to continue in the future.
