I am an early stage investigator and assistant professor who joined the department of Pathology at the University of Maryland School of Medicine in May 2018.  I completed a master’s degree in Neuroscience at Brandeis University and worked in a neurobiology laboratory at the Massachusetts Institute of Technology for one year prior to enrollment in the Medical Scientist Training Program at the University of Michigan Medical School. At the University of Michigan, I rotated in neuroscience laboratories, but ultimately chose to study protein trafficking in cancer cells due to a personal interest in cancer biology. My interest in neuroscience remained, and I became particularly intrigued by the molecular diversity demonstrated by brain tumors. I then pursued residency training in anatomic pathology and neuropathology at the Johns Hopkins School of Medicine and pursued both basic and clinical postdoctoral research projects investigating the diagnosis and pathogenesis of gliomas.

My main research focus is brain-specific invasion programs in glioblastoma. Glioblastoma is the highest grade diffuse glioma and the most common primary malignant brain tumor in adults. Diffuse gliomas have a unique ability among both primary and metastatic brain tumors to travel along white matter tracts, namely the corpus callosum, to establish bilateral, unresectable disease. Because of the ability of glioblastoma tumor cells to sparsely infiltrate normal brain, it is particularly difficult to identify the furthest extent of glioblastoma spread at both the gross and microscopic level. These tumors are therefore often recurrent, with only one-third of patients surviving for more than 5 years. The over-arching goals of my research are to identify and clinically target those biological pathways that allow high grade gliomas to traverse and colonize the unique microenvironments present in the brain.
