Susan Lambrecht's lab studies plant physiological ecology, focusing on how climate and other abiotic factors shape variation and evolution of plant functional traits.

Dr. Shaffer's Lab studies the physiological ecology of vertebrates, focused primarily on linkages between energy expenditure, behavior, and life history evolution in free-ranging birds. His lab uses a variety of novel data logging technologies to monitor behavior as well as conventional methods to measure energy expenditure and physiological performance. 

Our research combines field, museum, and molecular genetics approaches to address questions in evolution, ecology, and wildlife conservation biology. Our primary research focus is on American pikas and Urban Wildlife.

In the deVries Lab, we study what and how marine invertebrates eat and defend themselves from predators in order to understand how diet and morphology can help shape the ecology of an ecosystem. We further explore how environmental change may alter these relationships. We examine these concepts in coastal ecosystems by integrating tools from animal behavior, stable isotope ecology, aquaculture, genetics, biomechanics, engineering, and robotics.

Larabee Insect Biomechanics and Evolution Lab

Fredrick Larabee's lab studies insect morphology and biodiversity, particularly how mouthpart morphology influences insect ecology and evolution. His lab uses techniques ranging from behavior and 3D imaging to molecular phylogenetics and geometric morphometrics.

Kate Wilkin's lab investigates how fire interacts with plants, plant communities, ecosystems, and our communities from wilderness areas to the wildland urban interface. We are proud to be part of the NSF at 91猎奇, and are excited to collaborate on interdisciplinary projects.

We study the effects of alcohol exposure on development using fruit flies as a genetic model. Our current projects involve examining the interactions between alcohol and epigenetic regulation of gene expression, as well as the links between alcohol and neurodegeneration.

We are interested in the molecular and genetic mechanisms of neural development and behavior in the microscopic nematode C. elegans.  Specifically, we are interested in neural circuit formation and function of the phasmid sensory circuit.  These studies may help us to understand neurological disorders such as autism and schizophrenia.

How does the environment of a cell regulate its behavior? Our lab studies how chemical changes alter cell behaviors. We focus on acid levels, also called intracellular pH (pHi). Cells generate acids as a result of normal cellular processes, and cancer cells are more basic than normal cells. We showed that increasing pH in normal cells is sufficient to induce cancer cells behaviors. Current questions include: How does increased pHi promote cell proliferation? Paradoxically, how does increased pHi promote cell death? How does increased pHi work with oncogenic Ras-signaling to promote metastasis? Which molecules mediates these processes, and how does this occur?

Ouverney Lab

Our research focuses on the characterization of emerging uncultivable pathogenic Bacteria and Archaea associated with humans.  Most prokaryotes in natural environmental sites are thought to be uncultivable.  Some of these prokaryotes are also present in humans and have been recently associated with human diseases, such as bacteria in the Candidate Division TM7 associated with the oral disease periodontitis.  More specifically our research interests are to discover the natural sources of human-associated TM7 bacteria and to establish a TM7 bacterium model to further understand its role in the human body. 

Text: The PhAGE lab uses microbes to study how living things evolve. We focus in particular on viruses that infect bacteria (called 鈥渂acteriophages,鈥� or 鈥減hages鈥� for short). Our lab addresses questions such as: 1) How do viruses evolve to withstand increasing temperatures? 2) How do viruses evolve to infect new host cell types? Our research has broader applications to the emergence of new diseases, adaptation under climate change, and evolutionary mechanisms in other living organisms.

 

Rech Environmental Microbiology Lab

Our major project focuses on the change of the soil microbial population in response to decreasing moisture in the Mojave desert. We are using molecular tools to characterize the populations in the soil samples collected along a precipitation gradient. Currently we specifically focus on the genes involved in the nitrogen cycle and we are beginning to elucidate the influence of available moisture on this cycle. In addition we are working with bacteria isolated from the red banded acorn worm. Our major interest is the production of bromoperoxidases by these isolates. This involves the isolation and characterization of the enzymes. 

Dinh Lab

The vasculature is composed of specialized endothelial cells that not only facilitate the exchange of oxygen and nutrient delivery, but is also the site of immune cell trafficking, underscoring its importance in disease pathophysiology. Post-capillary venules (PCVs) are a specialized type of venular endothelial cell that facilitate extravasation through binding of cell surface receptors, addressins, to their ligand on the immune cells. The Dinh lab鈥檚 long-term goal is to systemically delineate the transcriptional cues that dictate vascular segmentation, specifically venules, and how they change under inflammation.

Adams Pathogenic Microbiology Lab

The Adams Lab focuses on the epic microbial battle that takes place in your lungs everyday between dangerous pathogens and vigilant white blood cells. Caught in between are the poor lung epithelial cells that can be damaged in the process. What weapons do the microbes use to cause disease? What defenses can our white blood cells provide? And how can we help our lung cells survive it all? We investigate these questions by using a combination of approaches in microbiology, immunology, biochemistry, and computer science. Oh yeah, and we also love science puns.

Skovran Lab

Methylotrophic bacteria use single-carbon chemicals for growth and are important for the global carbon cycle. We are genetically engineering methylotrophic bacteria to recover rare earth metals from electronic waste for reuse in manufacturing. To facilitate these efforts, we use genetic, molecular, biochemical, and omics-based techniques to investigate the metabolism and homeostatic mechanisms needed for rare earth metal acquisition, storage, and use. Additionally, we are developing and implementing new tools for use in methylotrophic bacteria including CRISPR-Cas9 gene editing and gene silencing.

Katie Wilkinson's lab studies the muscle sensory neurons that innervate the muscle spindle and provide body position and movement information to the central nervous system. These neurons are essential for balance and motor control. Our lab is interested in understanding how these neurons translate muscle stretch into action potentials and what causes these neurons to malfunction. 

Our lab is interested in how the neuroendocrine stress response alters wildlife behavior, physiology, and molecular biology. Currently, we are studying the effects of stress during gestation in wild fence lizards and how that maternal stress alters offspring behavior, immune function, and redox balance.

The Huynh Lab studies how nutrients are metabolized and how this contributes to overall health. The way nutrients are metabolized and stored can have profound effects on most physiological processes. We use molecular biology as well as whole body physiology techniques to study how carbohydrate, lipid, and amino acid metabolic pathways are regulated, how they interact, and how dysregulation of these pathways can lead to diseases such as diabetes and obesity. We are particularly interested in how metabolic pathways are regulated by hormones and post-translational modifications.

Our research program focuses on understanding the molecular and cellular mechanisms limiting the proliferative capacity of cardiomyocytes, specialized cells responsible for heart contractility.  After a heart attack, cardiomyocytes die and are permanently lost resulting in pathological cardiac remodeling, heart disease, and human death. By understanding cardiomyocyte cell-cycle regulation, our lab aims to identify new therapeutic targets that may guide strategies in cardiac regenerative medicine to better treat ischemic injury and restore heart function.
