Research Interests

Our lab is interested in the role RNA-binding proteins play in the development and function of the nervous system. We begin by identifying rare variants that are linked to neurological diseases, including ALS-FTD and the dementias. By combining CRISPR/Cas9 gene editing and neuronal differentiation, we study how these variants alter RNA-binding protein function and ultimately modify disease risk. These findings feed into the development of novel drug screening assays to bridge the gap between mechanistic insight and early-stage drug development to correct disease-associated phenotypes.

Most significant discovery

A subset of mutations in the low complexity domain of the key ALS-FTD protein TDP-43 fundamentally alter its autoregulation, expression, and cause widespread transcriptomic instability (PMID:29556029). This work highlights how a single point mutation can alter an RNA binding protein’s function, cause far reaching transcriptomic modifications, and contribute to neurodegeneration.
