New Faculty Members at NBMG

A message from Jim Faulds: Please welcome several new members of the NBMG team. This includes Lora Robb, our new Business Manager, who will oversee NBMG’s fiscal and administrative functions and Matthieu Harlaux, an Assistant Professor in Economic Geology. In addition, our Geothermal Center is growing with the additions of Rozena Brecke (who is handling important administrative aspects of the Center), Cary Lindsey (a post-doctoral scholar), and Eli Mlawsky (Geothermal Data Manager). These additions will greatly enhance our ability to analyze natural resources in the state and region. Please see short biographies of everyone below. We are very fortunate to have such a talented group joining NBMG.

New Faculty Members at NBMG:

Matthieu Harlaux, Assistant Professor–Economic Geologist
Dr. Matthieu Harlaux recently joined the Nevada Bureau of Mines and Geology and the College of Science at the University of Nevada, Reno as an Assistant Professor in economic geology. Dr. Harlaux received his MS in Geosciences from the Ecole Nationale Supérieure de Géologie in 2012 in Nancy (France). Then, he completed a PhD in Geosciences from the Université de Lorraine in 2016 (Nancy, France) focusing on granite-related tin-tungsten deposits in France. After completing his PhD, Dr. Harlaux joined the University of Geneva (Switzerland), where he did a two-year postdoc working on tin deposits in the Peruvian Central Andes.

Dr. Harlaux’s research focuses on understanding the formation processes of hydrothermal ore deposits. He uses a combination of field-work and modern analytical techniques (LA-ICP-MS, MC-ICP-MS, ID-TIMS, SIMS) for studying the trace element and isotope geochemistry of rocks, minerals, and fluid inclusions. More specifically, his research interests concern the processes at the magmatic-hydrothermal transition that occurs at the end of magma crystallization when exsolution of high-temperature volatile fluids occurs. This research aims to better understand the physico-chemical conditions (temperature, pressure, salinity, pH, gas content, and metal content) allowing the deposition of metal-bearing minerals by hydrothermal fluids.

Dr. Harlaux is excited to concentrate his research on the Nevada’s metallogeny, which has an incredible variety of hydrothermal ore deposits, including Carlin-type gold deposits, porphyry copper deposits, and epithermal gold-silver deposits, among the most important. Dr. Harlaux will help to strengthen the economic geology group at NBMG and to develop new research projects in strong collaboration with the mining industry and other universities. One of his ambitions will be to develop a new laboratory at NBMG focusing on the study of fluid inclusions applied to hydrothermal systems. His work will examine the ore-forming processes (fluid mixing, cooling, fluid-rock interaction, etc) in link with the Cenozoic magmatic and tectonic evolution of Nevada.

Lora Robb, Business Manager
Lora Robb joined NBMG in December as its new Business Manager. Her role includes overseeing the Bureau’s financial, administrative, and human resources operations working closely with the Director to make sure everything runs efficiently and effectively. She has worked in land use and water resources planning and as a business manager for several public agencies in the Reno area including Reno-Tahoe Airport Authority, Washoe County, Truckee Meadows Water Authority, and Truckee Meadows Regional Planning Agency. Lora holds an MA in Geography from California State University, Chico, and grew up in Truckee, California.

Lora is excited to join NBMG and return to a world where earth science and mapping are core to the organization’s mission. Her first real job out of college was working for the U.S. Geological Survey’s Mapping Division so joining the Bureau feels like returning home. When not at work, Lora is often with her husband Paul hiking, camping, boating, and otherwise exploring the wide open spaces of the great state of Nevada.

New Staff at Great Basin Center for Geothermal Energy

Rozena Brecke, Administrative Assistant
rbrecke@unr.edu, 775-682-8855
Rozena attained a dual degree from the University of Nevada, Reno Honors Program, earning a BA in Philosophy, a BS in Health Sciences and a minor in Biochemistry (2000). She pursued an internship at the UNR’s Medical School, and presented at Cancer Research conferences in the U.S. and abroad, with plans of an MA in Biomedical Ethics. After a change of plans and searching for her purpose and passion, in 2004 she opened up her own business, a tiny organic grocery store called Vegetus, Latin for “fresh, whole, lively and sound.” In 2006, she decided that it was time to seek that advanced degree, closed up shop, but then life happened, quite literally, and she welcomed her son, Soren, into the world.

In 2014, Rozena returned to University of Nevada to work at the Wolf Shop, the student-owned and operated campus store, where she curated the General Books department, led the bookstore’s first U.S. Passport Acceptance Facility and ultimately did her best to inspire and support students to become ‘real’ adults. In 2018, she transferred as an Administrative Assistant to the Great Basin Center for Geothermal Energy, housed in the Nevada Bureau of Mines and Geology, where she is proud to contribute to the global transition to renewable energy.

Rozena loves clean food, plants, great coffee, libations, ideas, kindness and humor. When she is not reading or cross-wording in the sunshine, she is appreciating the warm sound of vinyl in her 1938 brick home with the love of her life, son, and cat, Tuna.

Cary Lindsey, Postdoctoral Scholar

Upon completion of the program, she accepted a Data Science Fellowship at the National Center for Ecological Analysis and Synthesis (NCEAS), where she worked as the technical point of contact for researchers and working groups and assisted in managing data, instructing in data lifecycle best practices, performing statistical analyses, and presenting data through both static figures and interactive web applications. She was also a key player in the design and implementation of a new open science software portal for managing projects and disseminating data and results at NCEAS.

Emily is excited to join NBMG and apply her knowledge of database design and data workflow best-practices to managing and growing NBMG’s rich data stores. She will also utilize her software background in the design and implementation of new data dissemination portals to make NBMG’s data more available and discoverable.

New Structural Geologist at NBMG—Dr. Andrew Zuza

A message from Dr. Jim Faulds, NBMG Director and State Geologist:
We are very pleased to welcome a new faculty member to NBMG—Dr. Andrew Zuza. Dr. Zuza brings expertise and innovative approaches in structural geology and tectonics to NBMG.

zuza

Dr. Andrew Zuza recently joined the Nevada Bureau of Mines and Geology and the College of Science at the University of Nevada, Reno as an Assistant Professor. He received his BS in Geology from Cornell University and PhD from UCLA. Andrew’s research is primarily focused on continental deformation and the evolution of orogenic systems. He uses a mix of traditional field-based structural geology methods and modern analytical techniques, including geologic mapping, balanced cross-section construction, geo/thermochronology, metamorphic petrology, and analogue modeling. His past research has been focused on the evolution of the Tibetan Plateau’s northern and southern margins—both in northern Tibet and across the Himalaya—and he has conducted mapping-based research in India, China/Tibet, Mongolia, South Africa, and the western United States.

Dr. Zuza is excited to concentrate his research on Nevada’s unique geology, which is ideal for studying continental tectonics because late Cenozoic Basin and Range extension has exposed several important Phanerozoic orogens. His work will examine some of the enigmatic middle- to late-Paleozoic events, including the Antler and Sonoma orogenies, as well as the Jurassic-Paleogene Cordilleran thrust systems. To better constrain these pre-Neogene events, he is also focused on restoring the relatively recent extension and normal faulting that has been affecting Nevada since the Miocene. Detailed reconstructions of Cordilleran and Basin and Range deformation are important for economic geology purposes, and can help locate hydrocarbon reservoirs or ore deposits.
