He is a professor of oncology, neurology and neurological surgery at Johns Hopkins University School of Medicine. Dr. Holdhoff’s expertise is in primary brain cancers and central nervous system lymphomas. He earned his medical degree from Freie Universität Berlin, received his doctorate degree at Charité University Medicine Berlin. Dr. Holdhoff completed residency training in internal medicine at Johns Hopkins Bayview Medical Center, followed by a fellowship in medical oncology at Johns Hopkins Hospital with research training at the Ludwig Center for Cancer Genetics and Therapeutics (Kinzler-Vogelstein lab). As a clinical investigator in neuro-oncology, his research is focused on novel trials and translational biomarker studies in malignant gliomas and primary central nervous system lymphomas. He has led and contributed to numerous clinical trials, publications and presentations. Dr. Holdhoff serves as the director of the solid tumor inpatient service at the Sidney Kimmel Comprehensive Cancer Center. He is passionately involved in mentoring and teaching of fellows, residents and students. He is the director of the UCNS-certified neuro-oncology fellowship program at Johns Hopkins, and he is a teaching attending physician for the Osler internal medicine residency program. Dr. Holdhoff is highly rated in 19 conditions, according to our data. His top areas of expertise are Glioma, Glioblastoma, Astrocytoma, and Brain Tumor.

Christine L Hann, completed her MD and Ph.D. at Jefferson Medical College/Thomas Jefferson University follwed by an internal medicine residency at the University of Chicago Hospitals. Following a fellowship at Johns Hopkins University in Hematology and Oncology, Dr. Hann joined the Johns Hopkins Sidney Kimmel Comprehensive Cancer Center as a member of the Upper Aerodigestive Cancer Program and sees patients with non-small cell and small cell lung cancer. Dr. Hann's research focus is on developing novel therapeutics for lung cancer, particularly small cell lung cancer (SCLC) and neuroendocrine tumors (NETs) such as carcinoid tumors of the lung. As a faculty member she is involved in both clinical and laboratory research. Specific research projects include: 1) Studying mechanisms of resistant to small molecule inhibitors of the antiapoptotic protein, BCL-2 using patient-derived xenograft models. Her preclinical work has led to an NCI-sponsored Phase 1/2 clinical trial combining a BCL-2 inhibitor with a TORC1/2 inhibitors which is currently underway (NCT03366103). 2) Preclinical evaluation of various therapeutics including epigenetic modulators (LSD1 inhibitors) and nanoliposome chemotherapy in SCLC PDXs; 3) Modeling and characterizing chemoradiotherapy resistance in preclinical models of SCLC. She, along with Dr. Luigi Marchionni in Biostatistics and Dr. Phuoc Tran in the Department of Radiation Oncology, were recently awarded a 5-year NCI-sponsored U01 grant to study mechanisms of chemoradiation resistance in SCLC. Dr. Hann is PI of several trials in SCLC and NSCLC and is leading investigator-initiated clinical trials in SCLC and NETs. Dr. Hann is highly rated in 15 conditions, according to our data. Her top areas of expertise are Small Cell Lung Cancer (SCLC), Lung Cancer, Non-Small Cell Lung Cancer (NSCLC), and Squamous Cell Lung Carcinoma.

Dr. DeZern is a Professor of Oncology and Medicine at The Johns Hopkins University School of Medicine. She is active in the Division of Hematology Malignancies, Leukemia Program at the Sidney Kimmel Comprehensive Cancer Center at Johns Hopkins. Dr. DeZern has expertise in aplastic anemia, myelodysplastic syndromes, paroxysmal nocturnal hemoglobinuria, acute myeloid leukemia, and bone marrow transplantation. Dr. DeZern received her medical degree at The Johns Hopkins University School of Medicine. She completed a residency in internal medicine at Johns Hopkins, followed by fellowships in medical oncology and hematology, as well as obtained a Masters in Clinical Investigations at the Bloomberg School of Public health. Dr. DeZern is a member of the American Society of Hematology, the American Society of Clinical Oncology, and the American Society for Transplantation and Cellular Therapy. Dr. DeZern’s principle research activities consist of designing and conducting clinical trials that test investigational new therapies and approaches in the treatment of bone marrow failure (aplastic anemia and myelodysplastic syndromes). She has specific expertise in the use of alternative donor bone marrow transplantation in patients with severe aplastic anemia and trials of novel therapeutics for patients with myelodysplastic syndromes. Additionally, she has taken a rigorous approach to the study of diagnostics and supportive case (such as transfusion practices) in these patient populations. She is or has been the Principal Investigator for a number of multicenter trials in collaboration with the MDS Clinical Research Consortium, the Eastern Co-operative Oncology Group (ECOG)-ACRIN and now the Bone Marrow Trials Clinical Trials Network (BMTCTN). She is the Study Chair for the multi-site BMTCTN study (CHAMP) investigating the role of haploidentical donor transplantation using post-transplantation cyclophosphamide in patients with relapsed several aplastic anemia. Dr. DeZern is the local PI as well as the Deputy Chair for The National MDS Study, a collaborative natural history study of the NHLBI and the NCI. As a clinical investigator with a focus on translation of novel treatments to the clinic, Dr. DeZern’s goal is to improve outcomes for patients with bone marrow failure at the bedside and in her research environment. Dr. Dezern is highly rated in 27 conditions, according to our data. Her top areas of expertise are Myelodysplastic Syndrome (MDS), Chronic Myelomonocytic Leukemia (CMML), Acute Myeloid Leukemia (AML), Bone Marrow Transplant, and Bone Marrow Aspiration.
