Timothy is a doctoral candidate in the Department of Bioengineering at Stanford University. He works in a diverse range of research fields, including mammalian cell signaling and bacterial cell shape. He received his undergraduate education at the University of California, Berkeley and earned dual degrees in Bioengineering and Physics. During his time as an undergraduate, he performed research in super-resolution microscopy at UCSF and in magnetics at Berkeley. In recognition for his studies, Timothy was awarded the Departmental Citation award in Bioengineering in 2007. Now a graduate student at Stanford, Timothy studies mammalian cell signaling in Markus Covert's laboratory. He uses live-cell microscopy and computational modeling to study the dynamics of the immune response in single mammalian cells. More recently, he has been exploring high-resolution fluorescence microscopy techniques to study bacterial cells and how they define their shape. Timothy is dedicated to teaching, having developed course material at both Berkeley and Stanford as a teaching assistant. He also participates in the Chinese Undergraduate Visiting Research Program, where he acts as a research mentor to visiting Chinese undergraduates from Tsinghua and Peking University. In addition, he has been active in the Bioengineering Department, serving as the intramural sports coordinator and leading several intramural sports teams.
