###[Mackenzie Gavery](http://students.washington.edu/mgavery/Welcome.html)
My research aims to improve our understanding of the physiological responses of marine invertebrates to natural and human-driven environmental change. Specifically, I am interested the role of epigenetics, processes that can alter gene activity without changes to the underlying DNA sequence, in mediating environmental responses in shellfish. I am using the Pacific oyster (Crassostrea gigas) as a model to examine the role of DNA methylation in regulating interactions between genes and the environment. Through this work I hope to better understand the pathways through which environmental contaminants, such as endocrine disruptors, induce physiological changes and to determine whether these induced changes can be passed on to future generations

I am currently a masters student in Steven Roberts’ lab at the University of Washington in the School of Aquatic and Fishery Sciences. My general research interests are studying aquatic ecosystem health as a function of environmental change, with an emphasis on the study of epigenetics.
