Research
Highlights: |
|
The
Theoretical Biophysics Group at FIU is involved in several research
projects in the area of biological physics. The major projects include
theoretical and computational investigations of protein folding
dynamics, protein
aggregation, and protein engineering.
The group
is equipped with
several SGI workstations and a 16-node Linux cluster. Each node
consists of a powerful dual core processor and the cluster has a
total of about two Terabytes of disk space.
I am especially interested in the small peptide folding and protien
misfolding. I am also interested in broadly related fields of
biological physics such as mathematical modeling of the dynamics of
infectious diseases, SOC, and complexity.
