John Stix has studied active volcanoes for 26 years, specializing in volcanic gases, eruption mechanisms, and the impact of volcanic activity. He teaches undergraduate and graduate courses in volcanology, natural hazards, and environmental geology. He also is involved in field courses, where he exposes students to hands-on observations of natural processes such as volcanic eruptions and floods. He has been involved in many training courses and workshops in Canada, the US, and Latin America to teach volcanology. He has collaborated extensively with colleagues in Colombia, Costa Rica, Nicaragua, and Ecuador in volcano studies and volcanic hazards. From 2003 to 2010 he was the Editor-in-Chief of the Bulletin of Volcanology, the leading international journal related to the study of volcanoes and volcanism. He is currently part of an international team to drill into an active silicic magma body beneath Krafla volcano in Iceland.
