Research
Throughout my research career, I have been dedicated to uncovering mechanisms of synaptic
development, maintenance, and plasticity. I am interested in how early-life events
can disrupt these mechanisms, often with long-term consequences. I focus largely on
excitatory synapses, particularly those located on synaptic structures called dendritic
spines, small protrusions off of dendrites that are the sites of 90% of the excitatory
contacts in the brain. Specifically, I aim to elucidate mechanisms by which the responsive
capacity of synaptic structures, known as structural plasticity, can be altered during
brain development. Although structural plasticity is a major component of the process
of synaptic plasticity, which is involved in everything from learning and memory to
addiction, it is still poorly understood. Changes indicative of altered structural
plasticity of dendritic spines have been observed in epilepsy, autism, chronic stress,
and depression models, signifying its importance in a broad range of neurological
and psychiatric disorders. As such, a long-term goal of my research is not only to
uncover the mechanisms underlying normal brain development, but also to provide a
new line of research on which to base therapies for multiple neurodevelopmental deficits.
