Graduate Student Ambassadors

Our graduate student ambassadors act as a resource for prospective graduate students. In addition to regularly reaching out to a diverse array of undergraduate students, they are happy to answer any questions regarding the graduate application process and life as a graduate student in the Department of Atmospheric Sciences. Please feel free to send an email directly to one of our ambassadors, or send your questions to and we will direct you to the appropriate person!



Matthew Graber

  • Matthew's research is about improving tornado predictability using weather regimes. It's research that goes into both climate change and severe weather. His hobbies include running and watching sports in general, hiking and being outside, trying different kinds of coffee, and hanging out with my friends. He is excited to be a graduate student ambassador because he is looking forward to outreach events and being a mentor to other students.
