Abstract :
One hundred years
ago, D’Arcy Thompson – a nineteenth century polymath, working at
the turn of the
twentieth century – wrote a monograph, “On Growth and Form”, in which
he pondered the
geometry of living forms and how it emerges in the process of Morphogenesis.
Thompson was
ahead of his time. Since then, progress of Developmental Biology and
Molecular
Genetics uncovered many if not most of key genes and molecules involved in
Morphogenesis,
yet Thompson’s agenda of understanding how developmental processes
actually specify
the geometry of tissues, limbs and organs is far from complete. A particular
challenge is to
bridge the gap between microscopic scales, where molecular mechanisms
operate, and the
macroscopic scales of animal “shape and form”.
This challenge
offers much for a Physicist to think about. This talk will focus in particular
on the mechanical
aspects of morphogenesis i) examining the role of mechanical stress in
regulation of
growth and ii) seeking a quantitative understanding of tissue flows observed
in morphogenesis.
At the interface of Physics and Biology we will find some new biology
and new physics.
