Research Highlights:
Beam Dynamics

* Implemented genetic algorithms for optimization of accelerator performance and design.
* Simulatied of beam-beam interactions and electron cooling as a part of the design for the proposed Medium-energy Electron-Ion Collider (MEIC) at Jefferson Lab
* Designed and implemented a new three-dimensional wavelet-based solver for the Poisson equation with Dirichlet boundary conditions, optimized for use in particle in-cell simulations of charged-particle beams.
* Designed and implemented algorithms for simulation of coherent synchrotron radiation in charged-particle beams.


* Developed a new density-potential pair for spherical stellar systems appropriate for describing bulges in spiral galaxies, dark matter halos, dwarf elliptical galaxies, and both ordinary and giant elliptical galaxies, including galaxies with depleted cores.
* Used techniques from nonparametric function estimation theory to develop new empirical models for dark matter halos.
* Investigated dynamical implications of close supermassive black hole binaries both as an example of resonant phase mixing and as a potential explanation of inversions and other anomalous features observed in the luminosity profiles of some elliptical galaxies.

Nonlinear Dynamics

* Studied chaotic dynamical system by applying tools of differential geometry.
* Applied statistical, differential-geometric approach to chaos in low degree-of-freedom dynamical systems.
* Studied manifestations of chaos in time-dependent Hamiltonian systems and their implications for violent relaxation in the early Universe.
