The Use of Mt. Mazama Volcanic Ash as Natural Pozzolans for Sustainable Soil and Unpaved Road Improvement

Matthew Sleep
This Small Starts study offers sustainable road building materials for rural infrastructure, from an unlikely source. Approximately 7,000 years ago, the eruption of Oregon's Mt. Mazama blanketed the Klamath Basin region with a thick layer of volcanic ash. Matthew Sleep, an associate professor of civil engineering at Oregon Tech, investigated the use of this ash as a natural pozzolan for soil stabilization and unpaved roadway improvement. He found that the ash, prevalent in Southern Oregon, has… Read More

Understanding Human-centered AI through Data Integration and Analytics

David Yang
Human Centered Artificial Intelligence (HCAI) is an approach to developing and implementing Artificial Intelligence technology applications that focuses on the needs of individuals and communities who utilize these applications. This project intends to develop course modules and tools for students to understand human-centered AI methods and data requirements, conduct specific mobility analysis using AI-empowered technologies, and build multimodal technology solutions to improve mobility. The… Read More
