In 2012 she graduated magna cum laude from Pacific Lutheran University (PLU: Tacoma, WA) in the International Honors program with a BS and honors in chemistry, a BA in biology, and minor in Hispanic studies. During her stay at PLU, Michaela was a Presidential Scholar (4 year scholarship), played an active role in the on campus Women’s center, played in the on campus harp ensemble, was a resident assistant in a social action and leadership community, and was a student delegate in Oaxaca, Mexico for a semester as a part of Witness for Peace. During the summer of 2010, she worked as an undergraduate researcher (REU student) at Montana State University in Dr. David Dooley’s inorganic biochemistry lab researching the Michaelis-Menton substrate binding of pseudoazurin with nitrous oxide reductase. In 2011 she worked in Dr. Justin Lytle’s materials and electrochemistry lab studying carbon inverse opal monoliths. In April 2016, Michaela got married and her name changed from Michaela S. Burke to Michaela Burke Stevens.
