Philipp Ruprecht

I am a faculty member in the Department of Geological Sciences and Engineering at University of Nevada, Reno, since 2016. Most of my research focuses on the magmatic processes within the crust and upper mantle that drive volcanic eruptions and the formation of continental crust. I combine field work with geochemical and petrologic tools, while also including physical constraints during magma evolution. In particular, I am interested in the assembly of arc magmas and the timescales associated with formation, storage, transport, and eruption of those magmas.
I am also interested in the links of magmatic processes to the formation of mineral deposits and the processes that are controlled by magmatic fluids.

Xiaoliang Wang

Dr. Wang’s overarching research theme is to understand air pollutant emissions, transformations, and impacts. Specifically, his research interests include physical and chemical characterization of aerosols, pollution source emission measurement, and aerosol instrument development.
Dr. Wang has developed several widely used aerosol instruments. He is a co-inventor of nanoparticle aerodynamic lenses for efficiently delivering particles into aerosol mass spectrometers and the TSI DustTrak DRX Aerosol Monitor for measuring size-segregated aerosol mass concentrations in real time. He led the design of the DRI Portable Emissions Measurement System (PEMS) that has been used for characterizing gases and particles from vehicle exhaust, stack emissions, biomass burning, and biomass-derived syngas. Dr. Wang also led the design of the DRI Model 2015 Multiwavelength Thermal/Optical Carbon Analyzer that has been commercialized and used worldwide.
Dr. Wang has been studying real-world emissions from pollution sources with the goal of improving air quality management. His projects include researching dust emissions in underground coal mines, tailpipe and non-tailpipe (i.e., brake and tire wear, as well as road dust) emissions from vehicle traffic, toxic gas and particle emissions from the open burning of household solid waste in South Africa, smoke emissions from burning lithium-ion batteries and spacecraft-relevant materials, and mining fleet/industrial stack/fugitive dust emissions in the oil sands region of Canada. Recently, he participated in several projects to study the impact of visibility, air quality, and atmospheric deposition of particles generated from wildfires and prescribed burns in the Lake Tahoe Basin.
Dr. Wang is an active participant in several scientific organizations. He conducts peer reviews for scientific publications and funding agencies. He served as co-chair and chair of the Instrumentation Working Group of the American Association of Aerosol Research (AAAR) annual conferences and chair of the Young Investigators Committee of the AAAR.
Dr. Wang has been granted three patents and published three book chapters and 90+ peer-reviewed journal articles. He is the recipient of the 2020 AAAR Benjamin Y. H. Liu Award that recognizes outstanding contributions to aerosol instrumentation and experimental techniques. Most recently, he received the 2021 DRI Science Medal for his outstanding scientific contributions.

M. Rashed Khan

Khan Lab@UNR aims to study, design, and develop soft materials, unconventional processes, and reconfigurable micro/nanodevices that can be harnessed and optimized further for advanced biochemical, biomedical, and physicochemical applications. The lab is also keen to establish a multidisciplinary smart-manufacturing research group, including researchers from various backgrounds. Through short and long-term active collaboration, Khan Lab@UNR would like to address fundamental challenges associated with soft micro-device fabrication, 3D/4D (bio)printing, and patterning, advanced hybrid sensor manufacturing, biomedical device development – which are still unnoticed and under-explored, and need further investigation.

Additionally, our group also focuses on computational neuroscience and neurobioengineering. Under this research direction, we study human brain, brain functions, brain structure so that the established knowledge can be broadly applicable to general biomecical science and knowledge of the brain and brain-diseases.

El Hachemi Bouali

I am an applied geologist by training and an opportunistic scientist in practice, meaning I love geology but am interested in many areas of the natural sciences. I can abbreviate my research focus with the acronym GASP: geophysical and surface processes.

Geophysical Processes. I use geophysical and remote sensing instruments to study changes on the Earth’s surface and within the shallow subsurface. I will be starting a research project (early 2023) on utilizing passive seismic methods to map bedrock depth (or sediment thickness) as an indirect approach to identify buried faults and to study extensional tectonics of the Las Vegas valley.

Surface Processes. I use an interdisciplinary approach to study our dynamic Earth. A major research project I am currently working on (2021-future) is titled Analyses of spring water chemistry and microbiology in the Spring Mountains, Nevada. I use field and laboratory methods across multiple disciplines (geology, biology, and chemistry) to quantify physical properties of high-elevation springs and analyze microbial communities found in these springs.

I teach courses that are required or electives for the BS in Environmental & Resource Science and BS in Biology. I teach the following courses at Nevada State:

–GEOL 101A/L Exploring Planet Earth Lecture and Lab
–GEOL 333 Principles of Geomorphology
–GEOL 405 Geology of the National Parks
–NRES 322 Soils
–NRES 467 Regional and Global Issues in Environmental Science
–BIOL/ENV 494 Biology and Environmental Science Colloquium

I received a Ph.D. in Geology from Michigan Technological University, an MS in Geosciences and BS in Geophysics from Western Michigan University, and an AS from Kalamazoo Valley Community College. I was the Postdoctoral Fellow in Environmental Science at Trinity College (Hartford, CT) and a NASA Earth and Space Science Fellow while earning my Ph.D. I have also worked as a Geological Mapping Technician for two summers at Pictured Rocks National Lakeshore in the Upper Peninsula of Michigan where I assisted with the creation of ten surficial geology quadrangle maps by acquiring near-surface geophysical data and auger samples.

Helen J. Wing

Helen J. Wing is an Associate Professor of Molecular Microbiology in the School of Life Sciences at the University of Nevada, Las Vegas. She obtained her Ph.D. in Biochemistry from the University of Birmingham (UK) in 1997, where she studied transcriptional gene regulation in Escherichia coli. She worked with both Prof. Stephen J.W. Busby and Prof. John R. Guest in her first post-doctoral position, where she employed biochemical approaches to study transcription. In 2000, Helen moved to the U.S. to take a post-doctoral position with Marcia B. Goldberg M.D. at Harvard Medical School and Massachusetts General Hospital. It was here that she became interested in the transcriptional regulation of Shigella virulence genes and antimicrobial peptides. She joined the faculty at the University of Nevada, Las Vegas in 2005.
The primary focus of my research laboratory is virulence gene expression in the bacterial pathogen Shigella flexneri, the causal agent of bacillary dysentery, which is estimated to kill over 1 million people each year. All four species of Shigella harbor a large virulence plasmid, which carries most of the genes required to cause disease in the human host, including those required for invasion, type III secretion and actin-based motility, a process that allows bacteria to spread from one human cell to another. We are interested in the environmental cues, the timing and the molecular events that trigger the expression of virulence genes. We are particularly interested in the complex interplay between nucleoid structuring proteins, proteins that facilitate the packaging of DNA into tiny cells, and the transcriptional regulators of virulence in Shigella VirF and VirB.

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.

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.
