As an experimental petrologist, I use high temperature\u00a0and\/or pressure laboratory experiments to learn about melting, crystallization, diffusion, and other processes relevant to the behavior of volcanic systems. In some cases, I design experiments to\u00a0constrain the\u00a0temperature and depth of magma stored beneath a volcano. In other instances, experiments can place\u00a0constraints on how fast a lava flow\u00a0cooled. I also examine more fundamental topics, including the kinetics of crystal growth and the effects of thermodynamic\u00a0variables like temperature and redox state on magma crystallization. My research areas (via lab work and occasionally in the field) have included Hawaii, Chile, Mars, the Moon, and exoplanets! I am excited to be teaching several related courses, including Mineralogy (GEOL 250), Volcanoes (GEOL 194), and more to come.<\/p>","protected":false},"author":40,"featured_media":2199,"template":"","class_list":["post-1324","profile","type-profile","status-publish","has-post-thumbnail","hentry"],"acf":[],"_links":{"self":[{"href":"https:\/\/www.macalester.edu\/geology\/wp-json\/wp\/v2\/profile\/1324","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/www.macalester.edu\/geology\/wp-json\/wp\/v2\/profile"}],"about":[{"href":"https:\/\/www.macalester.edu\/geology\/wp-json\/wp\/v2\/types\/profile"}],"author":[{"embeddable":true,"href":"https:\/\/www.macalester.edu\/geology\/wp-json\/wp\/v2\/users\/40"}],"version-history":[{"count":6,"href":"https:\/\/www.macalester.edu\/geology\/wp-json\/wp\/v2\/profile\/1324\/revisions"}],"predecessor-version":[{"id":1361,"href":"https:\/\/www.macalester.edu\/geology\/wp-json\/wp\/v2\/profile\/1324\/revisions\/1361"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/www.macalester.edu\/geology\/wp-json\/wp\/v2\/media\/2199"}],"wp:attachment":[{"href":"https:\/\/www.macalester.edu\/geology\/wp-json\/wp\/v2\/media?parent=1324"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
