I have\ \ been involved in the development and application of several models that simulate\ \ these processes.I have worked with emergency managers, Volcanic Ash Advisory\ \ Centers, and specialists from more than a dozen volcano observatories around\ \ the world to improve the accuracy of volcanic ash forecasts, both for aviation\ \ safety and for ground-based communities. From 2010-2020 I served as co-chair\ \ of the World Meteorological Organization\u2019s Volcanic Ash Scientific Advisory\ \ Group, an expert panel dedicated to advising Volcanic Ash Advisory Centers\ \ on the science and practice of volcanic ash-cloud detection and forecasting.My\ \ professional life began as a mud logger working on the North Slope of Alaska\ \ in 1980-81. While studying for my master\u2019s degree at Stanford in 1982-84,\ \ I worked part time for the Tectonophysics branch of the USGS in Menlo Park,\ \ California, where I assisted with hydraulic fracturing stress measurements,\ \ and studied the growth of fractures and the development of breakouts, i.e.\ \ stress-induced zones of failure, around boreholes in sandstone.My Ph.D. work\ \ at Stanford, from 1984-1988, under Professor David Pollard, involved field\ \ and laboratory study of the growth of surface faults above a shallow dike\ \ in Long Valley Caldera, California. A second half of this study focused\ \ on how the dike heated groundwater that erupted to produce several large explosion\ \ craters, the Inyo Craters, north of the town of Mammoth Lakes.After completing\ \ my Ph.D., I worked from 1988-1990 as a post-doctoral researcher in the Geophysics\ \ Institute at the University of Karlsruhe, Germany. My tasks included compiling\ \ data for the European part of a World Stress Map project, and examining the\ \ state of stress at a deep drillhole site in northern Bavaria.At the Cascades\ \ Volcano Observatory, from 1990 through the late 2000s, I concentrated on the\ \ role of water in the style and timing of eruptions. This work involved, for\ \ example, an examination of correlations between rainfall and gas explosions\ \ at Mount St. Helens; on the conditions that produced explosive phreatomagmatic\ \ eruptions at Kilauea, and effects of turbulent water-magma mixing on eruptive\ \ style.Since the late 2000s, I have been involved primarily in volcanic ash\ \ hazards, as described above." additionalType: personal statement - '@type': TextObject abstract: "2021: \u201CComparing the hazards of wildfire smoke and volcanic ash\ \ in the Pacific Northwest\u201D, invited talk in the Cascadia Wildfire and\ \ Urban Smoke seminar series, sponsored by Portland State University and the\ \ Cascadia Innovation Corridor Iniative (search for it on YouTube)" additionalType: staff profile page abstract - '@type': TextObject abstract: "2020: \u201CProtecting air travel from volcanic ash in the coming decade\u201D\ , invited talk V08-15 at 2020 American Geophysical Union Fall Meeting." additionalType: staff profile page abstract - '@type': TextObject abstract: "2016: \u201CForecasting Ashfall Impacts from a Yellowstone Supereruption\u201D\ , USGS Menlo Park Public Lecture, May 26, 2016, https://www.usgs.gov/media/videos/forecasting-ashfall-impacts-a-yellowstone-supereruption" additionalType: staff profile page abstract email: lgmastin@usgs.gov hasCredential: - '@type': EducationalOccupationalCredential name: 1988 Ph.D. Geomechanics, Stanford University - '@type': EducationalOccupationalCredential name: 1984 M.S.
