​The faculty of the Division of Hematology are responsible for teaching, clinical care and research in all aspects of Hematologic Disorders.  Our division has physicians and mid-level providers who are devoted primarily to clinical care and clinical research, physician scientists who divide their time between the lab and the clinic and scientists who spend their time focused primarily on laboratory research.  Because we take such an integrated approach to the diagnosis, treatment and curing of blood disorders we are able to move treatments from the bench to the bedside in a significantly more timely fashion.  Our patients have access to cutting edge treatments because our physicians and scientists are on the forefront of research in this critical area of medicine.

We invite you to get to know our faculty members better by taking the time to browse through their individual pages.

 Results From Hematology : Selected site

Blood Cancer & BMT Secondary - ​Pediatrics

Dr. Bernt is a physician-scientist who cares for children with leukemia and directs a laboratory research program studying leukemia biology and epigenetics.

Blood Cancer & BMT

Dr. Brewer leads the psychosocial team for the Bone Marrow Transplant program.  He works closely with Dr. Caspari to care for patients and families in the Blood Cancer Program.

Blood Cancer & BMT Secondary - Molecular Biology Program

Dr. Degregori is a leading expert in leukemia research and the Associate Director for Basic Science at the University of Colorado Cancer Center.

Patricia Ernst

​Blood Cancer & BMT Secondary - ​Pediatrics

Dr. Ernst directs laboratory research programs that focus on discovery of epigenetic regulatory mechanisms in leukemia and and in regulating stem cells to improve transplantation. An additional focus is the development of the hematopoietic system and the regulatory networks that coordinate self-renewal and differentiation.

Blood Cancer & BMT

Dr. Gutman directs the Allogeneic Bone Marrow Transplant (BMT) program and is a leading expert in the use of umbilical cord blood derived stem cells for BMT.  He oversees a broad range of clinical programs and trials.

Bradly Haverkos

Blood Cancer & BMT

Dr. Haverkos is an Assistant Professor of Medicine whose interest and expertise is in bone marrow transplantation and aggressive lymphomas with a focus on T and NK/T-cell associated lymphomas. His research is grounded in translating basic science discoveries into novel management and treatment strategies that can be studied in early phase clinical trials, which will eventually lead to improved patient outcomes.

Blood Cancer & BMT

Dr. Jordan serves as the Chief of the Hematology Division and directs a research program focused on the development of novel therapies for the treatment of leukemia.

Tanisha Joshi, Ph.D.

Dr. Neff is a physician-scientist who cares for children with leukemia and directs a laboratory research program studying leukemia biology and epigenetics.

Eric Pietras, PhD

Blood Cancer & BMT​

Dr. Pietras is a scientist who supervises a research laboratory focused on understanding the signals and molecular mechanisms that allow blood-forming stem cells to tailor their output in response to inflammation and other physiological challenges. His laboratory is also involved in understanding how these  mechanisms contribute to deregulated blood production in chronic inflammatory disease and leukemia.

Blood Cancer & BMT

Dr. Pollyea is the Director of the adult Clinical Leukemia Program, and cares for patients with leukemia, myelodysplastic syndrome (MDS), and related diseases.  He leads multiple clinical trials to investigate new treatments for patients with blood cancer.


Dr. Purev is a physician-scientist who cares for adult blood cancer patients. She focuses on marrow failure, myeloproliferative neoplasm, leukemia, bone marrow transplant, and adoptive cellular therap​y. Her research interest is to explore the role of immune system in the treatment of blood cancers.​​​

​Blood Cancer & BMT Secondary - Radiation Oncology

Dr. Rabinovitch is a professor of Radiation Oncology and works closely with the Hematology team to care for patients with various types of blood cancer.  She has been recognized multiple times as a 5280 magazine “Top Doctor.”

Blood Cancer & BMT

​​Dr. Robinson is an active clinical and basic investigator studying the molecular and genetic regulation of melanocyte development and melanoma, particularly the role of microRNAs in the regulation of melanoma associated genes. 

Daniel Sherbenou, MD, PhD

​Blood Cancer & BMT​

Dr. Sherbenou supervises a translational lab focused on the development and optimization of new treatments for multiple myeloma. In the clinic, Dr. Sherbenou takes care of patients with multiple myeloma and related plasma cell disorders.

Blood Cancer & BMT
