Program Director Welcome
Daniel Bowles, MD
Associate Professor, Medicine-Medical Oncology
Thank you for exploring the University of Colorado Hematology Oncology Fellowship Program, where our mission is to develop future world-leaders in academic cancer medicine by providing comprehensive education and training in clinical practice, laboratory research, and clinical, translational and basic science.
Our fellowship fosters a multidisciplinary approach to cancer and blood-disease care with experienced specialists. Our faculty come from diverse backgrounds with a wide range of interests including hematology, medical oncology, surgical oncology, pathology, radiation oncology, and radiology.
While their interests may differ they all share a common passion for educating young hematologists and oncologists. Our fellows are inquisitive scientists, compassionate skilled physicians, and outstanding teachers. Our program offers the environment and educational resources to help each trainee reach their goals and thrive in their career path. As you explore our program, virtually tour our affiliate sites, and discover Denver, we hope you will become excited and inspired by the innovation and cutting edge research of our faculty and fellows.

The first year of fellowship is focused on intense clinical training in both hematology and oncology. Trainees divide their time in two and three month blocks on inpatient-based hematology and oncology consult services at the University of Colorado Hospital, Denver Health, and the VA. UCH blocks are divided into solid tumor oncology and benign hematology.
Fellows learn the science of the diagnosis and treatment of hematologic and oncologic diseases, the art of consultation, and the skills necessary to care for patients with these problems. This inpatient training is complemented by weekly outpatient continuity clinic and sub-specialty clinic experiences. Elective time during the first year allows for additional exposure to disease-specific sub-specialty clinics and the opportunity to work with leading faculty in areas of solid tumor oncology, hematologic malignancies, benign hematology, and palliative care.
Required clinical time in the second year includes one month of UCH benign hematology consults, two months of UCH medical oncology consults at UCH, and one month each on the consult service at Denver Health and the VA. Clinical research and laboratory-based research opportunities are plentiful and fellows are required to participate.
Additionally the second year of fellowship is comprised of training tailored to different tracks, listed below, selected by fellows based upon clinical and research interests.
Clinical Investigator Research Track
Recommended for those fellows anticipating a career in academic clinical research, and will allow fellows to team with a mentor to grow their clinical research skills.
Clinical Educator Track
Designed for fellows interested in a career focusing on medical education. Trainees interested in this particular track will receive funding support from the Department of Medicine.
Clinical Excellence and Quality Improvement Track
Designed for fellows interested in a career in clinical practice, and will focus on their clinical training.
Laboratory Based Research Track
Tailored to fellows desiring a laboratory based career and will focus on developing the skills needed for an independent lab career.
BMT Track
Designed for fellows interested in specializing in blood cancers
Your third and final year of fellowship will be devoted to completion of the research training for those in the research tracks and to broadening the clinical experience for those in the clinical track. Clinical time in the third year includes two months of benign hematology consults and one month of medical oncology consults at UCH.
Outpatient clinic experience during the first year involves a weekly general oncology and hematology clinic at the VA or Denver Health that allows the fellow continuity and autonomy with a panel of patients.
A second weekly clinic during the first year varies according to rotation site, with an additional general oncology and hematology clinic during the VA block, a breast cancer clinic during the Denver Health block, and sub-specialty clinic time selected according to interests and education goals during the two blocks at UCH.
Clinic experience during the remaining fellowship training years involves at least one weekly continuity clinic and additional sub-specialty clinics coordinated according to the fellow’s training track and area of interest.
In addition to clinics, three hours per week are dedicated to educational conferences for fellows. Conferences include didactic presentations from expert on various hematology and oncology topics, as well as journal club, grand rounds, and morbidity and mortality discussions presented by fellows. Discussions of patient cases during this conference time provide an open format to explore challenging clinical issues with faculty and other fellows.
