Current Graduate Students


Six graduate students currently work with me in the geochronology-isotope laboratory and earning their respective degrees at The University of Texas at Austin. They have a variety of topics but share a common theme in integrating field work with isotope work.


Staci Loewy
Tectonic history of the Proterozoic Arequipa-Antofalla Terrane, northern Chile
Field mapping, U-Pb geochronology, isotope geochemistry

Christopher McFarlane
Jointly supervised by W. Carlson
Examing isotopic and major element equilibria in metamorphic mineral systems.
U-Pb and Sm-Nd geochronology, geothermobarometry

Jamey Jones
Tectonic history of S. Colorado (Wet and Sangre de Cristo mountains), specifically testing the 
existence and implications of an exhumed Proterozoic brittle-ductile transition. 
Field mapping, structure, metamorphism and U-Pb geochronology. 

Adam Krawiec
Investigating the link between the Nagssugotqidian and Rinkian orogens of West Greenland.
Field mapping, U-Pb geochronology, isotope geochemistry

Roy Fuller
Timing and nature of deformation and metamorphism in the Heimefrontfjella Range, Antarctica.
U-Pb and Sm-Nd geochronology, geothermobarometry

Liz Roller
Petrogenesis of the late- to post-tectonic granites of the Llano Uplift of central Texas.
Sm-Nd, Rb-Sr, common Pb isotope geochemistry and U-Pb geochronology 


Past Graduate Students

Christopher Whitefield

Currently employed Midland Valley Services, New Braunfels

Catherine Christoffel
Thermotectonic history of the Halland region, Sveconorwegian Orogen, southwestern Sweden
Field mapping, U-Pb geochronology, metamorphic geology (finished December 1997)
Currently employed Cococo, Midland

Jennifer Piontek Matzel
Bimodal magmatism in southwestern Sweden
Field mapping, U-Pb geochronology, Sm-Nd
Currently pursuing a Ph.D. at MIT

Michelle Roth
Lithotectonic mapping of a proposed crustal boundary in the Nagssutoqidian Orogen, West Greenland.
Field mapping, U-Pb geochronology, isotope geochemistry
Currently pursuing a teaching career. 


I am currently seeking enthusiastic graduate students interested in applying isotope geology to any number of geological problems. If the main thesis of the work includes isotopic work but is outside my own expertise, joint supervision is common at UTA. If interested contact me directly and see the Department of Geological Sciences for general information regarding application and deadlines.
