  The density dependence of the symmetry energy in the equation of state of
asymmetric nuclear matter (N/Z $>$ 1) is important for understanding the
structure of systems as diverse as the atomic nuclei and neutron stars. Due to
a proper lack of understanding of the basic nucleon-nucleon interaction for
matters that are highly asymmetric and at non-normal nuclear density, this very
important quantity has remained largely unconstrained. Recent studies using
beams from the Cyclotron Institute of Texas A$&$M University, constraining the
density dependence of the symmetry energy, is presented. A dependence of the
form E$_{sym}(\rho)$ = C($\rho/\rho_{o})^{\gamma}$, where C = 31.6 MeV and
$\gamma$ = 0.69, is obtained from the dynamical and statistical model analysis.
Their implications to both astrophysical and nuclear physics studies are
discussed.
