Welcome to Water Chemistry & Technology Research Group at UC Riverside!

2016 Liu

Our group's research is focused on the understanding and application of aquatic chemical processes to improve water quality, design treatment processes and provide more reliable water supplies. We face great challenges on the availability of high-quality water resources. Aquatic chemistry plays a pivotal role in both the engineered and natural systems of water cycle. Our research focuses on the applications of aquatic chemistry principles to our benefits in engineered applications such as water purification and wastewater reclamation, as well as to understand how various redox and interfacial chemical processes influence natural systems such as estuarine, surface and groundwater. We aim to understand these important steps of water cycle with a "source to tap and beyond" approach. We seek to integrate fundamental principles of surface chemistry, electrochemistry and chemical kinetics modeling with advanced analytical capacities to address these issues. In addition, we are active in outreach activities to serve our community in science education, raise public awareness on water issues and inspire the next generation of professionals and scientists. If you would like to learn more about us, please take a look at our website, check our research opportunity webpage and feel free to contact me for more information. We are always excited to hear from colleagues and potential students who share an interest in these interdisciplinary fields.
