Dr. Dueck is a biostatistician with expertise in cancer clinical trial design, development/testing of patient-reported outcome tools, and statistical analysis of patient-reported outcomes. Dr. Dueck has been a key collaborator with Dr. Mesa and the MPN QoL Study Group team in the development/testing of the MPN-SAF total symptom score, and more recently the MFSAF v4 with Dr. Mesa and the Critical Path Institute.


Angela Fleischman, MD, PhD


Assistant Professor of Medicine, University of California Irvine



Dr. Angela Fleischman is a physician-scientist investigating hematologic malignancies. She integrates her research with the clinical care of patients with these diseases. Fleischman's longstanding interest in blood cell development began during her PhD graduate studies at Stanford. After completing her MD and PhD at Stanford, in 2005 she moved to Oregon Health & Science University (OHSU) for her internal medicine residency and medical oncology fellowship. She joined the University of California, Irvine in July 2013 as an assistant professor to develop her independent laboratory group focusing on the pathogenesis of myeloproliferative neoplasms. Her overarching research goal is to identify what drives disease initiation in myeloproliferative neoplasms and to ultimately translate her scientific discoveries into therapeutic benefit for patients.


Adolfo Enrique Diaz, MD MSc


Assistant Professor, Mays Cancer Center at UT Health San Antonio at MD Anderson

Office Phone: 210-450-1820 



Dr. Diaz is a Faculty member in the Division of Hematology-Oncology. He completed his medical training with honors at the Pontificia Universidad Javeriana (Colombia) and his Internal Medicine residency at New York University. He completed his Fellowship in Hematology-Oncology and also received a Master of Science in Clinical Investigation and Translational Science degree, both from University of Texas Health Science Center San Antonio. His research and clinical interests focus on improving outcomes in patients with lymphomas and also on health care disparities.

Darpan Patel, PhD


Associate Professor/Research of Nursing, Graduates School of Biomedical Sciences at UT Health San Antonio MD Anderson



The long-term objective of Dr. Patel's research is to investigate 1) how exercise and natural products modulate growth of tumors, 2) the signal transduction of by which exercise and natural products attenuate muscle loss associated with cachexia, and 3) how discoveries made in the lab translate to the clinical population to improve patient outcomes. He uses molecular and biochemical techniques on prostate tissue, blood and saliva to test various theories on the benefits of exercise and natural products on inhibiting the onset and progression of prostate cancer. Dr. Patel's lab employs pre-clinical studies using transgenic, knockout and orthotopic animal models. He studies the translational potential for these outcomes in clinical studies to determine the molecular transducers that underlie adaptations associated with physical activity and natural product supplementation.


Dimpy Shah, PhD


Adjunct Assistant Professor, School of Medicine, Epidemiology and Biostatistics at UT Health San Antonio MD Anderson



Dr. Shah is a clinical epidemiologist with a focus on cancer epidemiology, survivorship, and outcomes research. She earned her doctoral degree in Epidemiology from University of Texas School of Public Health, Houston, completed her postdoctoral fellowship focusing on infectious diseases in immunocompromised cancer patients from MD Anderson Cancer Center, and is formally trained in microbiome and metabolomic research as part of career development grant from American Cancer Society. She has extensive experience in designing and conducting creative epidemiological studies to identify etiology and examine host-microbe-environment interactions in the development of infections and long-term outcomes in cancer survivors. She chairs a multinational partnership (Respiratory Viral Consortium in SCT recipients) with a common goal of developing evidence-based infection management guidelines for stem cell transplant survivors. The consortium consists of 15 cancer sites working together to describe the epidemiology and outcomes associated with post-transplant complications (e.g. viral infection, pneumonia, bronchiolitis obliterans, mortality) through the largest ever study in this population. They aim is to leverage this framework for collaborative studies in hematologic malignancy and hematopoietic transplant survivors. Dr. Shah also leads the microbiome working group at UTHSA to facilitate microbiome research and education. Her cancer epidemiology research program at UTHSA focuses on applying precision medicine and precision public health approaches to change clinical management and improve survival in cancer patients through multi-institutional collaborations for utilization of electronic health records and existing databases and biorepositories, development of outcome prediction algorithms and BIG DATA analyses. She also serve as an Advisory Council Member for Texas Cancer Registry.
