Grant Ochoa

Grant Ochoa (left) graduated from the University of Northern Colorado in Greeley, Colorado with a B.S. in Chemistry in 2016. Since then he worked as a quality control chemist for RFI LLC in Broomfield, Colorado, testing dietary supplements with analytical techniques such as HPLC. In September 2018 Grant moved to Seattle with his wife, Kristy, and dog, Marty, to attend the Chemistry PhD program at the University of Washington. As a member of the Synovec group, Grant researches computational and chemometric methods for GCxGC data analysis. In his free time, Grant enjoys hiking the beautiful Cascades range and taking trips with his family.
