Current Lab Members



charles3-1Charles G. Eberhart, M.D., Ph.D. (Professor; Pathology, Ophthalmology and Oncology; Director; Division of Neuropathology) studied meiotic cell cycle regulation in Drosophila spermatogenesis during his graduate studies at the University of Texas Southwestern Medical School in Dallas. After completing his MD and PhD degrees, he trained in Anatomical Pathology and Neuropathology at Johns Hopkins. He started his own laboratory in 2001.



Fausto J. Rodriguez, M.D. (Assistant Professor; Pathology and Oncology). Dr. Rodriguez received his undergraduate and M.D. degrees from the University of Missouri-Columbia. After graduating he pursued anatomic pathology residency, neuropathology fellowship and neuro-oncology research fellowship at Mayo Clinic, Rochester, Minnesota. He remained as faculty at Mayo for two years prior to assuming his current position at Hopkins. Currently he is an assistant professor of Pathology and Oncology. Dr. Rodriguez work aims to identify diagnostic, prognostic, and therapeutic biomarkers in primary brain tumors. His current research efforts specifically focus on the study of signaling pathways, such as MAPK and mTOR, and microRNA regulation in the biology of pediatric gliomas.


Eric H. Raabe M.D., Ph.D. (Assistant Professor, Pediatric Oncology and Pathology). Dr. Raabe completed MD and PhD studies at the University of Cincinnati College of Medicine, pediatrics residency at the Children’s Hospital of Philadelphia, and pediatric hematology/oncology fellowship at Johns Hopkins. He joined the Eberhart laboratory at a research fellow in July 2008 during his fellowship. Dr. Raabe was promoted to Instructor on the Oncology Department Faculty in July 2011 and Assistant professor in 2012. He uses human neural stem cells to create gain of function models of aggressive pediatric brain tumors. Dr. Raabe also uses cell lines derived from patients to test new drugs to help children with brain tumors. Dr. Raabe is a St. Baldrick’s Scholar: (


lauraLaura Asnaghi Ph.D. (Research Associate) received her Ph.D. in 2002 from the Dept. of Pharmacology at the University of Milan (Italy). She subsequently worked as postdoctoral fellow in the Laboratory of Cellular Oncology directed by Dr. Douglas Lowy (National Cancer Institute, NIH, Bethesda, MD, USA). She began working in the Eberhart Lab in fall 2008, and was promoted to Research Associate in fall 2011. Her projects are mainly focused on ocular oncology (uveal melanoma, ocular surface squamous neoplasia, retinoblastoma).


MingMing Yuan Ph.D. (Research Associate) Dr.Yuan received her Ph.D. from the Umea University, Sweden. She worked as postdoctoral fellow in the Dept. of Radiation Oncology and Molecular Radiation Sciences at Johns Hopkins University. She performed RNAi screening to identified novel tumor suppressor for glioblastoma. She joined the Eberhart, Rodriguez and Raabe laboratory in July 2014. Her current project focuses on low grade pediatric glioma.



harpreetHarpreet Kaur Ph.D. (post-doctoral fellow). Dr. Kaur received her PhD from The University of Toledo in Ohio. Her doctoral studies focussed on cell cycle regulation in cancer. She investigated the role of cell adhesion proteins in GBM during her three years of postdoctoral research at Case Western Reserve University, Ohio. She joined the Eberhart and Raabe laboratory in May 2012. Her current projects focus on the role of stem cell factors, specifically HMGA proteins, in adult and pediatric brain tumors. 


jeffrey Jeffrey Rubens M.D. (clinical-research fellow). Dr. Rubens is a pediatric hematology-oncology clinical and research fellow at Johns Hopkins Hospital. Dr. Rubens’ project focuses on LIN-28 in atypical rhabdoid tumors of the brain to help understand the malignant transformation of normal brain tissue and to help find curative therapeutics for this deadly tumor.




Antje Arnold Ph.D. (post-doctoral fellow). Dr. Arnold received her PhD from the University of Jena, Germany. Her doctoral studies focused on the derivation of human IPS cells with mRNA transfection. In her postdoctoral research at the Johns Hopkins University, Department of Radiology, she investigated the myelination status of primary human glial restricted progenitors cells after transplantation into myelin deficient mice with MRI. Dr. Arnold joined the Eberhart, Rodriguez and Raabe laboratory in August 2016. Her current projects focus on low- and high-grade gliomas.

Graduate Students


SamSamantha Semenkow is a graduate student in the Pathobiology program and has a BS in Molecular Biology, Biochemistry, and Bioinformatics from Towson University.  Her research focuses on how the Notch pathway and epigenetic mechanisms contribute to pathogenesis of adult Glioblastoma.




Allison Hanaford is a graduate student in the Pathobiology Program and has a BS in Biology from California State University. Her research focuses on developing therapeutic strategies for treating medulloblastoma, the most common malignant pediatric brain tumor.





Brad Poore is a graduate student in the Pathobiology Program who received his BS in Cell Biology and Neuroscience from Montana State University. His research focuses on examining the metabolic and phenotypic differences of Lin28A and Lin28B overexpression in gliomas, as well as the effect of glutaminase inhibitors on MYC driven cancers.
