Research Summary

Starting early in my education, I have been very interested in complex biological systems with relevance to human disease. During my four years at the College of William & Mary, I performed research in the lab of Dr. Margaret Saha defining the spatiotemporal development of neurotransmitter systems within the amphibian brain. I spent my summers during my undergraduate training in the multiple sclerosis lab of Dr. Timothy Vartanian at Harvard Medical School studying the regulation of oligodendrocyte myelination in the developing central nervous system. After completion of my undergraduate degree, I worked for two years at the University of Cincinnati College of Medicine in the lab of Dr. Erik Knudsen studying the regulation of cell growth by the retinoblastoma tumor suppressor, which led to several first-author publications, the most prominent of which describes the discovery of a novel oncogenic splice variant of cyclin D1 which we termed cyclin D1b and published in the Journal of Biological Chemistry in 2003.

Thereafter, I completed my medical and graduate training in the MD/PhD program at Georgetown University School of Medicine with my thesis research “Identification and Therapeutic Targeting of Novel Transforming Pathways in Human Glioblastoma Multiforme” performed in the lab of Dr. Todd Waldman. During my time at Georgetown, I gained expertise in the genetics of brain tumors and sought an opportunity to apply this knowledge in the field of diagnostic and translational neuropathology. I then entered a combined Anatomic Pathology Residency and Neuropathology Fellowship at UCSF, where I am currently in the final year of training devoted to neuropathology research with minimal clinical responsibilities. I am very interested in the application of molecular diagnostics for cancer pathology and the use of personalized targeted therapeutics based on the genetic profile of individual tumor specimens. I aspire to be an academic physician-scientist both attending as a neuropathologist and molecular pathologist, as well as continuing my research on the genetics of cancer.

During my graduate training, I made an important discovery in the field of cancer biology by identifying mutational inactivation of the STAG2 gene as one of the first common genetic causes of aneuploidy in human cancer (Solomon et al., Science, 2011). Moreover, I have subsequently discovered frequent truncating mutations of this cohesin complex gene STAG2 in urothelial bladder carcinoma (Solomon et al., Nature Genetics, 2013) and Ewing’s sarcoma (Brohl and Solomon et al., PLoS Genetics, 2014) which define a molecular subgroup of these tumors with distinct clinical outcomes. I now aim to define the role of cohesin gene inactivation in cancer pathogenesis and develop effective targeted therapies for the many patients whose tumors harbor cohesin mutations.
