Dr. Howerton is an Assistant Professor of Chemistry at Nevada State College. Dr. Howerton is actively involved in undergraduate research both as independent studies during the school year and as a mentor in summer NSF-INBRE. Her research centers around sporulating bacteria (Bacillus anthracis, Bacillus cereus, Clostridium difficile). Her students have studied germination kinetics to identify activation and inhibition compounds, synthesized potential spore germination inhibitors and studied the inflammation response initiated by these bacterial toxins and spore proteins. Also, as a researcher of C. diff, she is interested in the microbiome of the intestine before and after antibiotic use. Her students have studied bile salt hydrolases and their expression before and after rodents are treated with antibiotics. It is possible these enzymes play some role in the observable different susceptibility of rodents to C.diff. She is always up for new adventures if students present me with a workable research proposal!
Hans Moosmuller
Dr. Moosmüller’s interests include experimental and theoretical research in optical spectroscopy as well as its applications to atmospheric, aerosol, and climate physics. His research focuses on development and application of real time, in situ measurement methods for aerosol light absorption, scattering, extinction, and asymmetry parameter, and new optical remote sensing techniques. These measurement methods are being used for ambient air monitoring and vehicle, fugitive dust, and biomass burning emission studies. His latest research interests are fast, ultra-sensitive measurements of elementary mercury concentrations and fluxes and aerosol morphology and its influence on aerosol optical properties with a focus on fractal-like chain aggregates found in combustion particles. Dr. Moosmüller has also participated in the planning, fieldwork, and data analysis of several major air quality studies. During his first three years at DRI, he was responsible for the airborne ozone lidar research program under a cooperative agreement with the USEPA.
Before joining DRI, Dr. Moosmüller was at Colorado State University where he investigated Brillouin light scattering of spin waves and millimeter-wave effective line widths in thin metal films. He also did research on high-spectral-resolution lidar and coherent light scattering techniques. This work included the development of supersonic flow measurement techniques and the investigations of spectral line shapes. His earlier work at the Ludwigs-Maximilians Universität in Munich, Germany and the Max Planck Institute for Quantum Optics in Garching, Germany focused on laser remote sensing.
Brian Frost
The Frost group is interested in the development of new inorganic and organometallic complexes for use in aqueous and biphasic catalysis. Organometallic chemistry and catalysis remain exciting areas of research with many opportunities for fundamental, not to mention pedagogical, contributions. We are interested in the synthesis, structure, and reactivity of inorganic and organometallic complexes with emphasis on those applicable to catalysis. Techniques utilized in our laboratory include, but are not limited to, computational chemistry, multinuclear NMR spectroscopy (1H, 13C, 31P), UV-vis spectroscopy, mass specrometry, X-ray crystallography, and in situ IR using ASI’s ReactIR 4000.TM
Brenda Buck
Dr. Buck’s research focuses on medical geology – in particular how geological materials impact health. Currently, her work focuses on dust and hazards associated with dust exposure including those from asbestiform minerals, arsenic, and other carcinogens. She also performs research to better understand and quantify arid soil processes so that this knowledge can be applied in land use decisions, radionuclide and heavy metal contamination, biologic soil crusts, paleoclimate interpretations, landscape evolution, soil genesis, geomorphic hazards, and other applications.

Douglas Boyle
Dr. Boyle is a watershed hydrologist with over 25 years of experience in the field of hydrology and water resources with an emphasis in the development, implementation, and evaluation of complex computer-based hydrologic models to simulate watershed response to precipitation (rainfall and snowmelt). Integrated computer-based modeling of hydrologic processes to understand the impacts of historic and future climate on water resources in arid and semi-arid environments using paleoclimate information (e.g., pluvial lake shore dating, tree ring records and other climate indicators), global climate model estimates (e.g., paleo, historic, and future precipitation and temperature estimates from both statistical and dynamically downscaled studies), and instrumental ground-based information (e.g., NWS Co-op data, NRCS SNOTEL data, and PRISM data sets). Additional research interests include streamflow forecasting, water leasing and banking, water markets, GIS, remote sensing, parameter estimation and uncertainty analysis, and automated multi-criteria optimization. Dr. Boyle is a former Director of the Nevada Water Resources Research Institute.
Eric Wilcox
Dr. Wilcox’s research addresses the interactions among aerosols, clouds, and precipitation towards a goal of improved understanding of precipitation, cloud variability and radiative forcing of climate at regional scales. This work relies on satellite and in-situ observations, as well as simulations with numerical models of the atmosphere and climate.
Dr. Wilcox manages DRI’s climate modeling group, which implements a wide range of numerical models, including fine-resolution atmospheric models for regional climate studies and applied research in water resources and renewable energy projects, air quality and chemistry models, and global coupled ocean/atmosphere climate models.
Dr. Wilcox teaches Atmospheric Physics (ATMS 411/611) and Atmospheric Modeling (ATMS 746) at University of Nevada, Reno. He is an associate editor of the Journal of the Atmospheric Sciences, an associate director of the Nevada NASA Space Grant Consortium for DRI, and he serves as a member representative to the University Corporation for Atmospheric Research (UCAR) on behalf of the Nevada System of Higher Education.
Gannet Hallar
Dr. Hallar is an Assistant Research Professor with the Desert Research Institute, she directs Storm Peak Laboratory, a high elevation atmospheric science facility in Steamboat Springs, Colorado. This laboratory has undergone major changes under her leadership including new instrumentation, new research foci, new field courses, and a significant building expansion. Currently, at Storm Peak Laboratory, Dr. Hallar also work as adjunct faculty for the University of Nevada, Reno and teaches a graduate level field course in Mountain Meteorology.
The overarching theme of Dr. Hallar’s research is using high quality measurements of trace gases, aerosol physical and chemical properties, and cloud microphysics to understand connections between the biosphere, atmosphere, and climate, along with the impact of anthropogenic emissions on these connections. More specifically, currently her research uses high elevation sites, combined with airborne measurements, to study the formation processes of Cloud Condensation Nuclei (CCN) and Ice Nuclei (IN) and how differing formation processes impact mixed-phase cloud microphysics. This research topic is stemmed in many potential formation mechanisms of aerosols, including nucleation, secondary organic aerosols, and primary biological aerosol particles (PBAP’s).
Greg Pohll
Dr. Pohll’s major research interest is in numerical simulation of hydrologic systems. Evaluation of complex hydrologic systems requires tools from the traditionally fragmented fields of surface water hydrology, groundwater hydrogeology, and statistics. He is specifically interested in the development and application of numerical models that allow the end users to better understand the system and to make decisions within an uncertain environment. He uses state-of-the-art numerical tools to evaluate the all of the uncertainties inherent in the modeling environment so the end users understand how to quantify the worth of the modeling results in relation to the ramifications of the decision.
John “Jay” Arnone
My research focuses primarily on understanding the effects of global environmental change (a.k.a. “climate change”) on the functioning and structure of terrestrial ecosystems, and deciphering the underlying ecological mechanisms driving the responses. This includes the study of how rising atmospheric CO2, changes in ambient temperature, interannual climate variability (e.g. anomalously warm years or heat waves), reductions in biological diversity, and large periodic disturbances (e.g. wildfire) affect plant physiological processes, plant growth and survival, plant populations and plant communities, as well as ecosystem processes and feedbacks. Although my interests in ecology are broad, I am particularly keen on understanding how belowground processes are impacted by changing ambient environmental conditions (e.g. fine root dynamics, activity of soil fauna, soil hydrology and root biology). I attempt to bridge traditional ecological disciplines and seek out collaboration with scientists from other disciplines to address these wider-ranging ecological questions.
My research group and I also apply our expertise to directly address real-world environmental questions and challenges for clients such as the U.S. Department of the Interior, Southern Nevada Water Authority, Sempra Energy, American Vanadium, Washoe County Air Quality Management, U.S. Bureau of Reclamation, and the Gas Technology Institute.
