RICHLAND, Wash. – Students will highlight semester course projects, research and art as part of the fall Undergraduate Research Symposium and Art Exhibition on Dec. 11 and 13 at Washington State University Tri-Cities.

Members of the public are invited to attend as students present on their projects, which include the areas of history, political science, psychology, wine science, biology, fine art, English, mechanical engineering and environmental science.

Students will present posters of their research and course projects both days from noon – 1 p.m. in CIC 120. The art exhibition will be held from noon – 1 p.m. on Dec. 13, in the CIC Art Gallery.

“The Undergraduate Research Symposium and Art Exhibition provides our students with an excellent opportunity to practice communicating their research and course projects, which is an essential skill for when they go out into the professional environment,” said Allison Matthews, ���سԹ� clinical assistant professor of psychology. “We have a variety of great projects that will be on display.”

Some of the projects include:

• Research on plant-mycorrhizal fungal interactions
• Research on public health education programs for people who are at-risk for developing Type 2 diabetes
• An analysis of data from the Tri City Union Gospel Mission regarding client demographics, factors that influence homelessness and other related variables
• Investigating heat transfer on a surface subject to nanoparticle coating
• Nutrient limitation of algal and microbial biofilms in the Yakima Watershed
• The effect of pesticides on algal and microbial biofilms
• Cluster architecture and fruit composition as influenced by rachis tipping in wine grapes
• Title IX in regard to procedures on campus
• The Plastic Garden – a fine arts and engineering collaboration to construct a moving mechanical garden made of plastic and mechanical components

RICHLAND, Wash. – Six student projects were presented with $3,000 as part of the Chancellor’s Summer Scholars program to pursue research in academic fields including environmental and biological sciences, viticulture and enology, mechanical and electrical engineering and fine arts.

The Chancellor’s Summer Scholars Program offers students the opportunity to work collaboratively with a faculty mentor, developing skills to prepare them for a career in the science, technology, engineering and mathematics (STEM) or STEM-related fields. The projects are funded by Washington River Protection Solutions, with Atkins also providing funding for an engineering heat transfer project that is indicated below.

Addressing nutrient pollution in the Yakima River watershed

Student Rhenton Brimberry is working with Sarah Roley, assistant professor of environmental sciences, to study the effects of seasonal irrigation flows on microbes and algae in the Yakima River watershed. Microbes and algae can mitigate nutrient pollution by removing and processing excess nutrients, but most of these assessments have occurred in the non-irrigated midwestern United States. In the irrigated West, seasonal irrigation flows influence nutrient quantity and quality, and so may influence microbial nutrient uptake, as well. By examining algal and microbial responses to nutrient inputs, this project can inform management of nutrient pollution in irrigated agricultural watersheds.

A new method to quantifying mycorrhizal fungi to assist in rebuilding damaged ecosystems

Student Megan Brauner is working with Tanya Cheeke, assistant professor of biology, to develop and test a new molecular technique for quantifying mycorrhizal fungi in roots and soil. The fungi, known as arbuscular mycorrhizal fungi, form symbiotic relationships with most plant species, and have been shown to improve native plant growth in disturbed ecosystems. However, quantifying mycorrhizal fungi from environmental samples remains difficult. Development of this technique will be useful for other fungal researchers and will allow further investigation into the effectiveness of mycorrhizal inoculations in ecological restorations.��

Effects of native and invasive plants on mycorrhizal colonization

Like Brauner, student Ella Krinitsyn, is working with assistant professor Cheeke on research pertaining to the use of mycorrhizal fungi to restore native plant populations. Her research focuses on on evaluating the correlation between the percentage of mycorrhizal fungi colonization and the percentage of native or invasive plants within sites they are hoping to restore at the Meyer’s Point Environmental Field Station in Olympia, Washington. The project will provide valuable information needed to find effective restoration strategies to improve the growth of native plants and mycorrhizal fungi in landscapes impacted by disturbances.

Manipulation of grape cluster thinning toward improving quality of wine grapes

Student Vince Hewett is working with Bhaskar Bondada, associate professor of wine science, to determine the effects of grape cluster thinning (tipping), removal of flowers and berries at different stages of grapevine development on fruit quality. Cluster thinning is a routine vineyard management practice intended to produce high-quality fruits by optimizing crop load, however, grape growers and wine makers are often not content with the fruit quality results of cluster thinning. The issue of poor fruit quality, despite taking thinning measure to improve berry composition, can be resolved by fine-tuning the cluster-thinning strategy.

Investigating heat transfer on a surface subject to nanoparticle coating

Student Abraham Martinez is working with Mohammed Noor-A-Alam, clinical assistant professor of mechanical engineering, to determine the effect that nanoparticles have on a standard heat transfer surface that can be applied to technology ranging from central processing units in computers to turbine systems where temperatures need to be maintained within a specific range. With the ongoing surge of nanoparticle research in various applications, there is little literature on the effect that nanoparticles have on heat transfer surfaces. The cooling of appliances that require heat transfer requires the design of a system that maximizes the amount of heat transfer between the components of interest and surrounding environment. Nanoparticle coatings on heat transfer surfaces can be used to enhance heat transfer.

Incorporating mechanical, electrical and artistic components to create “The Plastic Garden”

Students Amy Alvarado, Adriana Iturbe, Jared Johnson and Marsobyn Salalila are working with Sena Clara Creston, clinical assistant professor of fine arts and digital technology and culture, to blend their expertise in engineering and the arts to create a moveable and engaging “Plastic Garden” that responds to its environment and aims to evoke emotional expression from its viewers. Specifically, the team will spend the summer using 3D printers, laser cutters and engineering techniques to create the inner mechanics of flowers within the garden, which will open and close as to respond to their environment. Upon end completion, the garden will feature a range of mechanically-based plants and creatures that respond to their environment.
