Biography:
Alan E. Berger is an applied mathematician at the Naval Surface Warfare Center - Dahlgren. He
earned his B.A. degree in Mathematics from Rutgers University in 1968, and Ph.D. in Mathematics
from MIT in 1972. He has done research in the areas of numerical analysis of elliptic equations,
free boundary problems, and singular perturbation problems. He has done interdisciplinary 
collaborative research in deriving computable expressions for the intensities of sidebands in 
solid state NMR spectra with magic angle spinning thereby permitting determination of the 
principal values of chemical shift tensors from experimental data, in modeling the reversible 
assembly of amphiphilic molecules into aggregates that can form liquid crystalline phases with 
preferential orientation distributions, and in modeling equations of state of certain polymers. 
Recent interests include the protein folding problem, which led to his current involvement in
analyzing gene microarray data.  Dr. Berger can be contacted at alan.berger@navy.mil
