Bio

 

I am an Associate Research Professor of Pediatrics in the division of Hematology/Oncology. In June 1997 I received my PhD in Neurobiology from the department of Psychiatry in the School of Medicine at Indiana University. The first part of my career was focused in the area of neuroplasticity and emotional memory, particularly with regards to stress and anxiety. In 2016, I joined the department of Pediatrics and refocused my career on the plasticity of the peripheral nervous system and how it recovers following exposure to chemotherapeutic agents, especially vincristine.
