Through her career, Emily hopes to bridge the gap between studies of terrestrial and submarine large igneous provinces! She also loves teaching and has industry experience in the fields of environmental consulting and mineral exploration. In her free time, Emily enjoys exploring rural post offices in Oregon with her corgi Regis!
