Scope & Research Focus: The complex
properties and functions of biological membranes
have been the subject of experimental and theoretical scrutiny for many years. Despite
continued progress in this direction, both from physical and biological perspectives, many
questions still remain unanswered.
An emerging topic of interest is the interplay of membrane geometry (i.e.,
shape and curvature)
and mechanics with chemistry (interactions with neighboring molecules in a fluid). An understanding
of related problems can
elucidate issues of cell motility and, more generally,
mechanisms of cancer.
In this RIT we will introduce and work on combining basic
analytical and numerical techniques
for the mechanics and perhaps chemistry of biomembranes.
Students can take 1-3 units of credit by attending
this RIT, and
studying and presenting a paper on an acceptable topic agreed on with one
of the organizers,
or discussing original research.
