Research Summary
Stress-induced cellular inclusions: are they liquid-liquid phase separation? Do their kinetics change in aged cells? Let’s find out!
Research Statement
My training as a research scientist has taught me to view protein folding as a dynamic process that affects every single thing that happens in the cell. As a postdoc, I’ve chosen to focus on how protein “misfolding” can be an adaptive mechanism for cells challenged with environmental stresses. Specifically, I’m building on work pioneered in the Gardner lab that interrogates the yeast stress-responsive puncta formation and SUMOylation of the transcriptional repressor Cyc8. I aim to establish this protein as a model of stress-induced adaptive liquid-liquid phase separation. I am also interested in how these phenomena change as cells age.
