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.

Bridge Pile Foundations Subjected to Liquefaction-Induced Lateral Spreading

Arash Khosravifar
The overall goal of this research is to improve the seismic safety and resiliency of highway bridges in the Pacific Northwest during earthquakes. Past earthquakes have shown that liquefaction-induced lateral spreading can be a major cause of collapse for pile foundations. Bridge engineers generally agree that pile foundations must be designed for: (a) lateral spreading loads caused by liquefaction of soils adjacent to piles, and (b) inertial loads during shaking resulting from the… Read More
