Use of molecular tools to understand microbial activities and resolve water reclamation problems 

Pitiporn Asvapathanagul

Research lab

Dr. Asvapathanagul's research focuses on using molecular tools to understand microbial activities and resolve problems in biological water reclamation processes and in the environment. She developed several molecular primers and probes for bacterial detection in water reclamation plants. Dr. Asvapathanagul is also interested in developing a novel system for sewage highly containing fat, oil and grease. She serves on the Water Environment Federation's Student and Young Professionals and Water Reuse committees. Her research has been published in Applied Environmental Microbiology and Water Research and other prestigious journals, as well as at conferences around the world. She joined the CSULB Civil Engineering and Construction Engineering Management Department as an Assistant Professor in 2012 after completing her Ph.D. at University of California Irvine.

Ted Yu

Research lab

Dr. Yu focuses on both computational and experimental research. His computational research closely examines chemical processes at the atomic level. This helps determine the mechanisms that govern the performance of electrochemical systems, which sometimes are too difficult to do with experiments. Once a model is established, computational research can be used to screen thousands of materials quickly, making it easier to determine which materials are the best candidates for further development. In addition to modeling, his work involves building rechargeable lithium batteries, applying the knowledge gained from computer simulations. Experimental battery research involves synthesis of battery materials, assembly of the cells, testing the cells on a battery tester, and detailed materials analysis. Dr. Yu holds a Ph.D. in Chemical Engineering from Caltech and worked as a postdoctoral researcher at UCLA.
