Project Scientists

  • Christopher Walthers Christopher Walthers
    • B.S., Biomedical Engineering, University of North Carolina, Chapel Hill
    • Ph.D., Biomedical Engineering, UCLA

    Chris is a Project Scientist in the Chen Laboratory. During his Ph.D. in the lab of Dr. James Dunn at UCLA, Chris researched biomaterial- and stem cell-based approaches for tissue engineering intestinal smooth muscle cells. As a postdoctoral researcher with Dr. Stephanie Seidlits, he further developed his biomaterials research to study differentiation of neural stem cells in hydrogels mimicking the brain microenvironment to treat brain and spinal cord injuries. In his free time, Chris enjoys seeing the world and watching great films.

Graduate Students, Ph.D.

  • Laurence Chen Laurence Chen
    • B.S., Bioengineering, UC San Diego
    • Ph.D. Student, Chemical & Biomolecular Engineering, UCLA

    Laurence is a PhD student in the Chemical & Biomolecular Engineering Department at UCLA. While an undergraduate at UC San Diego, he gained research experience in cartilage tissue engineering, nanobody engineering, and metabolic systems biology. Laurence is looking forward to apply synthetic biology in real world applications at the Chen Lab. He has adapted well to the beach bum lifestyle during his time in San Diego...except for surfing. He aspires to one day be a true surfer bro.

  • Meng-Yin Lin Meng-Yin Lin
    • B.S., Chemistry, National Chiao Tung University, Taiwan
    • Ph.D. Student, Chemical & Biomolecular Engineering, UCLA

    Meng-Yin is a PhD student in Chemical & Biomolecular Engineering. As an undergraduate student and research associate at National Chiao Tung University in Taiwan, Meng-Yin studied H-bond interactions between polymers and focused on synthesizing plasticizer metabolites to serve as biomarkers in diagnostic tools. She is now developing synthetic circuits to regulate cytokine levels in tumor microenvironments. Outside of lab, Meng-Yin enjoys great food and sometimes makes food (not guaranteed to be great food).
