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, and in the Lake Superior region, California, Greece, Oman and Venezuela.
Freya R. George -- Fulbright Postdoctoral Scholar
Freya did her PhD at Carleton University, Canada, graduating in May 2019. She was awarded a UK Fulbright Scholarship to perform research at Hopkins for 12 months, starting October 2019, and will thereafter switch become the Blaustein Postdoctoral Fellow within the Department of Earth & Planetary Sciences, JHU. Her work current research uses techniques in spatially-resolved microanalysis to investigate fluid mobility in subduction, and will focus on rocks from subduction complexes around the world. Freya has previously worked in the Sikkim Himalaya. She is broadly interested in petrology, and the rock record of heat and mass transfer in the lithosphere.
Robert M. Holder -- Postdoctoral Fellow
Robert joined Hopkins as a Postdoctoral Fellow in July 2018 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. His current work considers the metamorphic record of secular evolution in tectonics, and individual high-grade terranes in Minnesota, Nevada and Namibia. From September 2020 he will be an Assistant Professor at the University of Michigan, Ann Arbor. Students interested in graduate research that uses petrology and geochronology to answer questions in tectonics are encouraged to reach out to Robert.
Naomi A. Becker -- Second-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 and Norway.
Joseph F. Browning-Hanson -- Second-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.
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.
Dana C. Brenner -- Former Graduate Student (PhD 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.
