Dr. Monk is a senior scientist and co-director of the Vollum Institute. After earning her B.S. degree in Biochemistry from Elmira College in 2001, Kelly pursued doctoral studies at the University of Cincinnati/Cincinnati Children’s Hospital under the mentorship of Nancy Ratner and was awarded her Ph.D. in Cell Biology in 2006. She did postdoctoral training in the lab of William Talbot at Stanford University School of Medicine. In 2011, she was appointed as an assistant professor in the Department of Developmental Biology at Washington University School of Medicine in St. Louis, and was promoted to associate professor with tenure in 2016. Monk joined the Vollum Institute as co-director and full professor in 2017 and was named director of the Vollum/OHSU Neuroscience Graduate Program in 2018.

 Kelly began her independent career in 2011 and has since gained recognition as a leader in the fields of glial cell biology and neuron-glial interactions. Her work on Gpr126 and other aGPCRs has helped to lay the foundation for the rapidly growing aGPCR field. She and her team have discovered new roles for aGPCRs in the developing nervous system, were the first to delineate aGPCR functions in the adult nervous system during homeostasis and injury, and defined new activation paradigms, ligands, and downstream signaling mechanisms for this previously completely enigmatic receptor class. Beyond aGPCRs, she has leveraged the power of zebrafish genetics coupled with synergistic approaches in mouse, and her group is now armed with ~30 mutants from new forward genetic screens that can address key outstanding questions in glial cell biology and neuroscience including: glial fate specification and heterogeneity; the cell biology of myelination; mechanisms of glial-neuron and glial-glial interactions; glial support of neurons; and the contribution of glia to circuits and behavior.

Carla Taveggia, PhD

San Raffaele Hospital, Milan

Dr. Taveggia is Group Leader and the Director of the Division of Neuroscience at San Raffaele Hospital in Milan, Italy. After graduating in Biology at the University of Milan, she obtained her Ph.D. in Molecular and Cellular Biology at the Open University London, UK. She then moved at the NYU Medical Center, New York, US and pursued her post-doctoral studies in the laboratory of Dr. Jim Salzer, where she investigated the role of the axonal molecules controlling myelination. Her studies demonstrated that Neuregulin1 type III is an essential instructive signal for PNS myelination as its axonal dosage regulates the amount of myelin produced. During these studies she was supported by a post-doctoral fellowship from the US National Multiple Sclerosis Society.

In 2007 she was awarded the “Rita Levi Montalcini” Transition Career Award from Federazione Italiana Sclerosi Multipla. She thus moved back to Italy in 2008, to establish her research group at the San Raffaele Scientific Institute in Milan, where she has been since then. Here she continued to study the mechanisms controlling neuronal glial communication and identified the secretase ADAM17 as a post-transcriptional regulator of Neuregulin1 cleavage and activity. More recently, her laboratory identified in Prostaglandin D2 synthase and its signaling mechanism a novel pathway regulating PNS myelin formation and maintenance.

Dr. Taveggia’s main scientific interests focuses in understanding the molecular basis controlling myelin formation and maintenance in the PNS, in both physiological and pathological conditions, the cell biology of myelination and deciphering glia support to neurons.
