I am an Associate Professor at the
Physics Department of
Drexel University. My
research interests are the
study of: (a) the loss of spatial organization of neurons in the aged brain using
density maps, (b) the folding of the Alzheimer amyloid beta protein using
all-atom molecular dynamics, (c) growth of plaques in Alzheimer's disease using
cellular automata models, and (d) fluid flow through porous media using lattice

Programs that take advantage of Graphical User
Interfaces (GUI) as a means for research
- VIS Program: Tcl/Tk front-end for the Vtk
- PN Program: Tcl/Tk, C++, and OpenGL program for
the study of the correlation between senile plaques and neurons in the
- CW Program: C++, wxWindows, and OpenGL program
for the study of the morphological effects of senile plaques on
surrounding neurons in the Alzheimer brain.
- Distort Program: C++, FLTK, and OpenGL program
for the study of warping brain tissue images for the anatomical study
of the brain.
- LATG Program: C++, FLTK, and OpenGL program for
the study of the lattice gas cellular automata model for fluids in two
- CRUSH Program: Tcl/Tk and C++ program for the
study of close-packed disks and the
deformations in their arrangement from a growing space-occupying
central disk. Intended for the study of the interactions between a
growing senile plaque and neurons in its neighborhood.
Program: Tcl/Tk, C++, and OpenGL program
for the study of an interactive growing DLA.

in Physics. Little Tcl/Tk "applets"
for demonstrations of physics concepts. (To see the ticlets you need at least Tcl/Tk Plugin
Version 3 and Netscape, Internet Explorer, Konqueror, or Firefox).
Spheres Ticlet. Presents a little Tcl/Tk "applet"
with a rotating sphere around a fixed central one. You can set variable
elevation angle as well as rotational speed.
