Adam Kent is the Associate Dean for Graduate Programs and Faculty Advancement. Working closely with CEOAS leadership and faculty, Kent oversees graduate academic programs, identifies and coordinates faculty advancement and mentoring opportunities, and assists with long‐range planning, including new faculty hires. He also coordinates activities associated with promoting diversity, equity and inclusion within the college. Kent studies the behavior and evolution of magmatic and volcanic systems. He earned his Ph.D. in geology and geochemistry from the Australian National University, Canberra, Australia.
