Current group members...
Daniel R. Viete -- Assistant Professor
After receiving his PhD from the Australian National University, Daniel moved on to postdoctoral work at Monash University, followed by 12 months as a Fulbright Visiting Scholar at the University of California, Santa Barbara and then 20 months as a Marie Curie (COFUND) Junior Research Fellow at Durham University. He started as an Assistant Professor at Hopkins in July 2016. Daniel is motivated by questions in tectonics (in particular on the time scale/tempo and drivers of processes) and uses petrology, geochemistry and geochronology to address these questions. He works across the North American Appalachians and Irish/Scottish Caledonides, in the Lake Superior region and the Caribbean.
Freya R. George -- Blaustein Postdoctoral Fellow
Freya did her PhD at Carleton University, Canada, graduating in May 2019. She was awarded a UK Fulbright Scholarship to perform research at Hopkins 2019–2020, and is currently a Blaustein Postdoctoral Fellow in the Department of Earth & Planetary Sciences, JHU. Her research uses techniques in spatially-resolved microanalysis to investigate metamorphic drivers, deformation, and chemical and fluid mobility in crystalline rocks. Freya has worked in the Sikkim Himalaya. Her current work considers spectacular metamorphic rocks from Baltimore and multiple subduction zones, globally.
Naomi A. Becker -- Third-year Graduate Student
Naomi started as a PhD student at Hopkins in August 2018 after finishing her undergraduate studies at the University of North Carolina, Chapel Hill. Naomi’s current graduate research concerns records of subduction initiation in the Iapetus Ocean. She is also interested in the petrogenesis of plagiogranites and their utility in dating tectonomagmatic processes. Naomi’s fieldwork focus is on mafic–ultramafic complexes in Alabama, Norway and Oman.
Joseph F. Browning-Hanson -- Third-year Graduate Student
Joseph did his undergraduate at the University of Maryland, College Park before starting as a Research Assistant at Hopkins in June 2018 and then joining the PhD program in August 2018. Joseph is working on multi-mineral detrital records of the timing and tempo of the rifting of Rodinia. He is also interested in the origins of granulite-facies metamorphism in oceanic settings, and the fate of sediments at mantle depths. Joe’s fieldwork spans Tennessee and Virginia, Vermont and Quebec, and Scotland.
Supratik Roy -- upcoming Graduate Student (starting 2021)
Supratik received a BS in Geology (with a minor in Mathematics) from the University of Calcutta in 2017, and an MS in Geology from the Indian Institute of Technology, Dhanbad in 2020. He will start as a PhD student at JHU in 2021, working on heat sources for orogenic metamorphism during the Paleoproterozoic and implications for tectonic evolution through Earth history. Supratik is interested in integrating observations from structural geology and metamorphic petrology to better understand tectonic processes, and has a background in analog modelling of large-scale deformation. His previous fieldwork has included mapping in Rajasthan, India and the Democratic Republic of the Congo, and his PhD work will begin with a focus on regional metamorphism associated with the Penokean Orogeny, Upper Peninsula, Michigan.
Jerry L. Burgess -- Research Affiliate
Jerry joined Hopkins as the Director of the MS in Environmental Sciences & Policy and GIS programs after receiving his doctorate from the University of Maryland. His research is highly interdisciplinary, ranging from geology to exploring serpentine ecology community dynamics. Current research interests center around using petrologic and geochemical tools to investigate igneous and metamorphic rock histories, with focus on petrogenesis and the growth and evolution of the Appalachians. Jerry's work focuses on Newfoundland and the Maryland piedmont.

Friends of the TeMPO Lab...
Dana C. Brenner -- Former TeMPO Lab Graduate Student (2016–2018)
Dana graduated with a PhD from Johns Hopkins University in 2018. Her final project focused on metamorphic geology, exploring the clumped-isotope signature of the the Alta Stock thermal aureole (and isograd sequence) in Utah. Dana is now Laboratory Manager for the Isotope Ratio Mass Spectrometry Facility at Hopkins. Her research interests still include the application of geochemical approaches to probe metamorphic processes, and she is actively involved in a project within the group that concerns the time scales of Grampian thermal activity in Scotland.
Robert M. Holder -- Former TeMPO Lab Postdoctoral Fellow (2018–2020)
Robert was a Postdoctoral Fellow in the TeMPO Lab July 2018–July 2020, after finishing his PhD studies at the University of California, Santa Barbara. He is broadly interested in petrology, petrochronology and tectonics, and has previously worked in Antarctica, Madagascar and Norway. Among various interests, some of his current work considers the metamorphic record of secular evolution in tectonics, and individual high-grade terranes in Minnesota, Nevada and Namibia. He is currently an Assistant Professor at the University of Michigan, Ann Arbor.
Herbert W. Fournier -- Queen's University
Herbert was an Instructor Professor at la Universidad Central de Venezuela 1999–2003 before moving to Canada where he earned his PhD from Queen's University in 2015. His research has considered tectonothermal histories of rock units of the Venezuelan Caribbean Mountain System, in addition to episodicity in records of crustal fluid flow (and associated heating) in Australia and Norway. He is currently working with the TeMPO Lab on the Cenozoic tectonic history of the southern Caribbean, as recorded in metamorphic rocks of the Cordillera de la Costa, Venezuela.
George L. Guice -- Peter Buck Postdoctoral Fellow at the Smithsonian Institution
George started at the Smithsonian in July 2019, after graduating from the PhD program at Cardiff University. His research considers mafic and ultramafic rocks throughout Earth history, with a focus on developing geochemical tools to aid assessment of petrogenesis and evolution in plate tectonics (regimes and products). Since moving to the Mid-Atlantic his work has focused on the tectonic origin of mafic–ultramafic bodies in the Baltimore Mafic Complex (including the Stateline Complex), in addition to Precambrian mafic–ultramafic complexes in other parts of North America and the world.
Will D. Junkin -- Geologist at the Maryland Geological Survey
Will started at the Maryland Geological Survey in 2018 after graduating with an MS from the University of California, Santa Barbara. He spent 2018–2020 mapping and describing metaigneous units in the Patapsco area of SW Baltimore (Relay and Savage 1:24k quadrangles), and has been working with the TeMPO Lab in further understanding the origin and significance of the Baltimore Mafic Complex (and associated units).
