Research Theme

Micro- and Nanoscale Biocomplexity
Proper development, function, and repair of tissues relies on how cells to a complex presentation of extracellular cues. My laboratory focuses on the understanding how cells interpret this complex environment at multiple spatial scales. The distribution of multiple proteins at the scale of single to hundreds of micrometers directs cellular coordination into functional tissues. At the nanoscale, the assembly, configuration, and dynamics of signaling ligands influences how cells respond to these powerful signals. Through the use of advanced techniques for patterning lipid bilayers (figure 1, movie 1, figure 2) and presenting biomolecules on a substrate (figures 3 and 4), my laboratory seeks to understand how these factors drive key functions of cells, ultimately leading to improved understanding of organism behavior and implantable devices.


Background and Education

Lance Kam is an assistant professor of biomedical engineering. He earned his doctorate in Biomedical Engineering in 1999 from Rensselaer Polytechnic Institute, developing tools that will lead to fine control over the attachment and growth of neurons on engineered surfaces. His interest in incorporating highly instructive proteins into these surfaces continued in his postdoctoral training at Stanford University through his work in supported lipid bilayers. Dr. Kam's laboratory builds upon these tools towards the investigation of cell interaction with spatially, temporally, and biomolecularly complex surfaces.
