DESCRIPTION:As cell biology moves to a more quantitative science\, there h
 as been an increasing need for new methods to study and manipulate individ
 ual cells and cell assemblies. In this talk I will describe our research i
 n developing microtechnologies that allow us to measure and manipulate cel
 ls for both fundamental biology and biotechnology. Our research focuses on
  two\ntechnologies: dielectrophoresis\, which acts as electrical "tweezers
 " for cells\, and microfluidics\, which we use to control the cell microen
 vironment. In this talk I will describe how we have combined these two tec
 hnologies to create a variety of enabling systems. For example\, we are us
 ing microfluidics and physical cell patterning to for modulating stem cell
  diffusible and contact-mediated signaling. We are also developing a numbe
 r of technologies (electrical\, optical\, etc.) to allow for image-based s
 orting of cells\, augmenting traditional microscopy with a sorting functio
 nality. Finally\, we have been developing electrical methods to separate c
 ells that are ideally suited for novel screens.\n
