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.

Erin Hannon

Erin Hannon is faculty in the Psychological and Brain Sciences department at the University of Nevada, Las Vegas. She received a Ph.D. Experimental Psychology in 2005 from Cornell University. Her research program combines her interests in cognition, culture, infant and child development, music and dance, and language. Her research examines how an individual’s culture-specific listening experiences influence his or her perception of music, the similarities and differences between musical and linguistic skills as they develop and perhaps interact during infancy and childhood, how we acquire the ability to move in time with music, and how developmental milestones in music perception might be related to other social, cognitive, and linguistic abilities and behaviors.

Joel Snyder

Dr. Snyder received a Ph.D. in Psychology from Cornell University and was a post-doctoral fellow at University of Toronto and Harvard University before starting the Auditory Cognitive Neuroscience Laboratory at UNLV. He is an expert on auditory perception and its neural basis and has published numerous empirical studies and literature reviews in top psychology and neuroscience journals. His research has been supported by UNLV, the National Institutes of Health, the National Science Foundation, the Army Research Office, the Office of Naval Research, and the REAM Foundation. Dr. Snyder’s research accomplishments were recognized with the 2009 Samuel Sutton Award for Early Distinguished Contribution to Human ERPs and Cognition, and the William Morris Excellence in Scholarship Award. He was also the UNLV nominee for the 2018 Nevada Regents’ Researcher Award.

We are a research group that thrives on collaboration. Through our interactions with collaborators, public health labs, and patients we have developed a research program that interrogates the following themes:

1) Wastewater genomics and COVID-19

Wastewater testing has been used for years to investigate viral infections, to study illicit drug use, and to understand the socioeconomic status of a community based on its food consumption. While tools are in place in many states to evaluate the presence of specific viral strains, the community has not needed previously to collaborate on a global scale to standardize procedures to detect and manage COVID-19 transmission. In response to this challenge, our laboratories in Arizona, Nevada, and Washington have developed collection techniques and genomic and bioinformatic approaches to harmonize and visualize the impact of SARS-CoV-2 infection and viral mutation rates in communities populated by local citizens and international tourists. Our findings will contribute to the development of best practices in sampling and processing of wastewater samples and genomic techniques to sequence viral strains, an area required for environmental surveillance of infectious diseases, and has the strong potential to improve the clinically predictive impact of the viral genotype on patient care and vaccine utility.

2) Rare neurological conditions

An association between the 16p13.2 copy number variation deletion and seizures has suggested that a) systematic suppression of each of genes in the loci might yield similar neurological phenotypes seen in the 16p13.2 deletion; and b) such genes might be strong candidates for harboring rare pathogenic point mutations. Through these studies, we discovered USP7 as a message capable of inducing abnormal neurological activity in brain organoids, cultured neurons, and loss-of-function mouse models. Together with collaborators at the Foundation for USP7-Related Diseases (www.usp7.org), our studies are centered on the mechanism by which USP7 gene dosage and rare variants can induce pathology. In addition, we have also identified other gene loci that mimic USP7-related disorders in human and animal models.

3) Ciliary biology and neurodevelopmental conditions

Large-scale studies have begun to map the genetic architecture of Schizophrenia. We now know that the genetic contribution to this condition arises from a variety of lesions that include a) rare copy number variants (CNVs) of strong effect; b) common non-coding alleles of mild effect; and c) rare coding alleles that cluster in biological modules. The challenge that has emerged from these studies is the requirement for large sample sizes to detect significant genetic signals. These findings intimate that SZ is genetically heterogeneous and manifesting potentially as a clinically heterogeneous group of phenotypes with discrete physiological drivers. To address this challenge and to complement the ongoing sequencing effort of cross-sectional SZ, we propose to sample individuals with extreme phenotypes (i.e., resistant to treatment: TRS) to potentially discover an enrichment of causal rare variants which would have otherwise not been observed or been difficult to detect in a large, random sampling of SZ. In addition, we will focus on the role of a specific biological module, the pericentriolar material (including the centrosome, basal body, and primary cilium) and how it relates to the development of the brain and behavior through the genomic and functional dissection of PCM1.

My research examines how people store and manipulate information over short intervals to solve problems and make decisions – what we typically call short-term memory. We use behavioral methods combined with non-invasive measurements of brain activity (primarily EEG and fMRI) to examine many basic questions about short-term memory: how does the brain represent information that’s no longer present in the environment? How are memory representations created, accessed, updated, and deleted when no longer necessary?

Donald Price

A major theme in my research is to understand how species adapt to diverse environmental and biological factors and diverge into new species. The evolutionary changes that permit species to survive and reproduce across a wide range of environments has resulted in a remarkable range of biological complexity.

My research group studies the interplay of behavior, ecology, genetics, and physiology to determine how species adapt to environmental changes and how diversification of populations leads eventually to the formation of new species. One focus of my group is the amazing Hawaiian Drosophila, which boasts up to 1,000 species in several taxonomic groups. Using genome sequencing and gene expression analyses coupled with detailed behavioral and physiological measurements we have identified genes that are involved in temperature adaptation between two species and between two populations within one species along an environmental gradient. We have also identified genes and epicuticular hydrocarbons that are involved in behavioral reproductive isolation and hybrid sterility between species. Initial studies have begun on the interaction with microbes, (bacteria and yeasts) that are important for food, internal parasites/symbionts, and possibly host-plant associations. In collaboration with others, we are also investigating the genetics of Hawaiian bats and birds, Drosophila melanogaster, the invasive Drosophila suzukii, and Hawaiian Metrosideros trees.

Paul Verburg

I am a broadly trained soil scientist with an interest in applying fundamental knowledge about soils to assess effects of natural and anthropogenic perturbations such as climate change, acid rain and land management on terrestrial ecosystems. I have worked in a variety of ecosystems including boreal forest, tallgrass prairie, Mojave deserts, and Sierra Nevada forests. In my research I use a combination of field, laboratory and modeling approaches to obtain a better mechanistic understanding of how soils and ecosystems function and respond to external stressors.
