Upcoming Presentations

 

SPRING  2021

“Materials-Driven Approach to Discovering and Understanding the Materials of the Future.”

April 30th (tentative) 4-5pm on Zoom https://cwu.zoom.us/j/81154413957?pwd=UUVoN2lnV0pSRVg5aFg0bTJHTGVJQT09

One of the most productive mechanisms for improving existing technology or developing entirely new technologies is to incorporate novel materials with ground-breaking properties.  What kinds of materials are well-suited to drive the technological innovations of the future?  Many will be correlated electron materials that boast “super” properties such as superconductivity, colossal magnetoresistance, colossal magnetocaloric effects, and many others.  One of the dirty secrets of correlated electron materials research is that our understanding of the physics that governs such properties is surprisingly underdeveloped.  Theories that both comprehensively explain correlated electron phenomena and, more importantly, predict which materials will exhibit them remain elusive.  In such an environment, new correlated electron phenomena are discovered experimentally, sometimes completely by accident, by studying the properties of new materials.  This materials-driven approach to discovering and understanding correlated electron properties will be discussed, including how it is used in undergraduate student research at CWU.

 

“The Bawa Health Initiative – Meeting Healthcare Challenges in Rural Cameroon, Africa." 

May 21 (tentative) 4-5pm on Zoom https://cwu.zoom.us/j/81154413957?pwd=UUVoN2lnV0pSRVg5aFg0bTJHTGVJQT09

Winter 2021

"Defining the Impacts of Environmental Exposures on Host-Microbiota Interactions."  

Chris Gaulke, Assistant Professor, University of Illinois at Urbana-Champaign ... and CWU alum!

Friday March 5th at 4-5PM (PST)

Humans are bombarded by thousands of dietary, chemical, and microbial exposures daily. Emergent work indicates that the gut microbiome interfaces with these exposures potentially mediating their effects on host physiology. However, we have limited insight into the mechanistic underpinnings of these interactions. In this seminar I will detail how my lab applies integrative cutting-edge molecular and statistical techniques to examine the interplay between the host, the gut microbiota, and the environment and how we aim to leverage this knowledge to promote human health.

“A Dead Tree's Excellent Adventure: The Ecology of Dead Wood."
Ken Bevis, Stewardship Biologist, WA Dept. of Natural Resources

January 22, 4-5pm (This will be presented on Zoom)

Join Zoom Meeting

https://cwu.zoom.us/j/81154413957?pwd=UUVoN2lnV0pSRVg5aFg0bTJHTGVJQT09

 

Ever wonder what happens when a tree dies in the forest? Follow along as we track the changes in the dead tree, from fresh dead, to hard snag, to soft snag to down log, and all of the life that follows in the decaying wood. The important ecological role of dead trees is explored, particularly by way of habitat use by the many species. In fact, almost 40% of forest wildlife are somehow dependent and tied to dead wood for their survival. Ken will explore how dead trees persist in the environment, how they change with time and some of the fascinating species associated with them, particularly woodpeckers. He might even play a song!

Fall 2020

"Lichen Population Genetics: North American Patterns of Diversity in Three Species." 
Dr. Jessica Allen, Eastern Washington University

October 23, 4-5pm  (This will be presented on Zoom)  

Join Zoom Meeting

https://cwu.zoom.us/j/81154413957?pwd=UUVoN2lnV0pSRVg5aFg0bTJHTGVJQT09

 

Abstract: Lichens are quintessential symbioses that grow in all terrestrial habitats on the planet. Though they are abundant and diverse, they are often mysterious. Population genetics and genomics tools can illuminate patterns and processes that govern how lichens move across the landscape and reproduce.

 

In this talk three charismatic species will be discussed: lungwort (Lobaria pulmonaria), wolf lichen (Letharia lupina), and rock gnome (Cetradonia linearis). Each species exhibits a markedly different distribution, reproductive life history, and history of human impact, resulting in some surprising genetic outcomes.

Previous Presentations

Winter 2020

Title: “Democracy, the Worst Form of Government” *

Presenter:  Dr. Aaron Montgomery, CWU Department of Mathematics  

Dr. Montgomery will discuss different methods of voting and how effectively these methods meet standards of fairness.  In particular, what Arrow’s Theorem means for the idea of the “will of the people” in a democratic election.  And, since there are always questions about the electoral college in election years, he will spend a few minutes discussing how the electoral college process impacts the fairness of US elections.

*except for all those other forms that have been tried from time to time...

2019

Title: “Removing Carbon from the Atmosphere: Carbon Sequestration in Kittitas Valley Soils.”

Presenter:  Dr. Carey Gazis, CWU Department of Geological Sciences

Carbon is being added to the atmosphere by humans through the burning of fossil fuels, deforestation, and cement production.  In this research, we are examining the carbon budget of soils in the Kittitas Valley in order to quantify their current carbon content and fluxes and assess their potential for removing carbon from the atmosphere.

 

Title: “Exercise as a Lifelong Polypill.”

Presenter:  Leo J. D'Acquisto, Professor, Integrative Human Physiology, Department of Health Sciences, CWU

Regular physical activity is a foundation for the prevention, management and treatment of illnesses associated with poor lifestyle habits.  The focus of this presentation will be on the connection among human structure function, physical activity habits, and cardiorespiratory fitness over a lifetime.

 

Title: “Tropical Biodiversity Genomics”

Presenter:  Adam Leaché, Professor, Department of Biology, Curator of Genetic Resources & Herpetology, Burke Museum of Natural History and Culture University of Washington, Seattle

Understanding the processes that promote population and species diversification is important for describing the composition of biodiversity, interpreting how ecosystems and biomes develop over time, and guiding decisions on how to preserve threatened biotas. The tropical rainforests of West and Central Africa contain spectacular species richness and endemism, yet the factors responsible for generating this diversity are understudied.

Screening of I-90 Wildlife Project Documentary Film, “Cascade Crossroads”.

Cascade Crossroads is a 30-minute documentary film chronicling the amazing story unfolding on Interstate 90 just east of Snoqualmie Pass in Washington’s Cascade mountains, where the intersection of a vital east-west transportation corridor and a north-south wildlife corridor resulted in historic conservation, collaboration, and innovation that led to the I-90 Snoqualmie Pass East Project under construction today.  Commissioned by the I-90 Wildlife Bridges Coalition, the film aims to not only share this unique story but also inspire action in other landscapes facing similar challenges between wildlife and roads. 

A trailer for the film is available at https://vimeo.com/166867310

2017

Title: “Investigating Life in a Tropical Dry Forest in Jalisco, Mexico:
SOBRE Mexico Scholars Present Results of their 2017 Summer Research.”

Climate models predict tropical storms will grow stronger as global temperatures rise. The SOBRE Mexico team investigated the response of a tropical dry forest (TDF) ecosystem to Patricia, a category 5 hurricane that struck coastal Jalisco, Mexico in October 2015. In addition, the team investigated parasite/host interactions in the tropical dry forest after the storm.

 

Title: “A Basal Deinonychosaur from James Ross Island, Antarctica and the Biostratigraphy of the Latest Cretaceous, Antarctic Dinosaurs.”

Presenter: Dr. Judd Case, Department of Biology, Eastern Washington University

 

Title: “Patterns, Sources, and Impacts of Variations and Trends in the Timing of Seasonal Transitions Over the Coterminous U.S.”

Presenter: Dr. Julio Betancourt, Paleoecologist, USGS

Day-of-year [DOY] metrics can define spring onset in the CONUS. These DOY metrics exhibit secular trends consistent with both natural variability and greenhouse warming. In the atmosphere, spring onset variations also appear linked to the Pacific North American (PNA) pattern and the Northern Annular Mode (NAM). By contrast, last spring frost, first fall frost, and the duration of the growing season in CONUS poorly tracks common climatic indices, and instead is modulated by the polar vortex.

 

Title: “The Creation of a Marine Park:  Twenty Years of Research on the Intertidal Mudflats of NW Australia.”

Presenter: Bob Hickey, Professor, CWU Department of Geography

Come learn about the science behind the development of marine parks in Roebuck Bay and Eighty Mile Beach, Australia, one of the few places on Earth where soft bottom intertidal mudflats support vast numbers of migratory birds.

 

Title: “From Bones to Behavior: Using Signs of Injury and Illness to Understand the Lives of Extinct Mammals.”

Presenter: Meaghan Wetherell, Associate Director of Institutional Effectiveness, CWU and Adjunct Lecturer CWU Department of Geology

This presentation will discuss how evidence of illness and injury can be used to piece together a picture of herd structure, lifespan, and defense mechanisms for a group of extinct mammals called oreodonts. In particular, we will cover the abundance of bite marks, infections, bone bruises, and fractures found on the cheekbones of one genus of oreodont, and how such injuries could relate to herd behavior.
