Ongoing research includes measuring and mitigating the impact of humans on surface and drinking water quality, with emphasis on small organic molecules.
Laboratory research focuses on evaluating advanced treatment processes aimed at removing nutrients and select contaminants during water and wastewater treatment. We use environmental chemistry and microbiology principles to enhance water quality and promote water reuse in the region.
Areas of research include advanced simulation methods and machine learning for performance assessment of structures subjected to extreme events; characterization of earthquake hazard and risk to the built environment with focus on reinforced concrete buildings and distributed systems; and uncertainty quantification in performance-based seismic design.
My research deploys 360-degree LiDAR sensors at intersections or other road sites with traffic questions. The high-resolution 3D cloud points data from LiDAR is processed into all-road-user trajectories. Data is then analyzed. Students can be involved in any step of the process based on interest, background knowledge, previous experience and research projects requirement.
Ryan is working with collaborators to test a new seismic lateral system for tall timber building. A 10-story building will be tested on the large outdoor shake table at University of California San Diego in summer 2022. Ryan expects to have funding for an REU student (ideally having completed junior year) to work on this project at UCSD in summer 2022.
We have paid and voluntary undergraduate research opportunities on water treatment, wastewater reclamation for reuse and COVID-19 monitoring through wastewater surveillance during regular semesters as well as summer. Initial training and mentoring will be provided. Students must take laboratory safety training prior to conducting the research.
We work on applications of advanced construction materials such as ultra-high performance concrete (UHPC) for future structures and infrastructure systems. Students may join any of the continuously ongoing experimental and laboratory activities that include UHPC mixing, material characterization testing, large-scale specimens fabrication, etc.
Pavement engineering and science
The Western Regional Superpave Center conducts local/ regional / global projects on pavement system stability, pavement construction quality management and pavement responses to transient dynamic loadings. Current research thrust: responsible use of materials for flexible pavement systems.
Interested in hands-on research on the response of foundations in earthquakes? Helical piles are one of the pre-manufactured deep foundation types that are commonly used to underpin foundations suffering from excessive settlements. This study evaluates the dynamic behavior of helical piles in dry and liquefiable soils through a scaled shake table tests.

My group researches the reactions of organic carbon in natural and engineering systems, with implications on carbon cycles and water reuse. We use state-of-the-art technologies to studying organic carbon, especially the quinone-phenol components, ubiquitous in natural and engineered water bodies.
