Research Interest

Dr. Toro’s research is focused on understanding the molecular basis for substrate specificity. Currently, she is working with Dr. Watt to understand how individual members of a family of enzymes known as lysine deacetylases (KDACs) select specific substrates from thousands of known cellular targets. Deacetylation is critical for proper regulation of many cellular processes and has been linked to numerous human diseases, such as cancer and inflammation.
