Minimal Supersymmetric Standard Model has all the ingredients to provide a successful inflation. The inflaton
is a gauge invariant flat direction which carries the Standard Model charges. I will discuss how such a model
predicts the CMB observations and provides hope for its detectability at LHC. I will also discuss how a thermal
production of neutalino in conjunction with MSSM inflation...

We will discuss the gravitino production in early universe from
scalar field which reheats the universe. Such production is pointed
out to be rather generic and modify usual cosmological scenarios
significantly. To be concrete, we will analyze several inflation models.

I will discuss the recently discovered gravitino overproduction from inflaton decay,
particualrly focusing on its implication for the SUSY breaking and inflation models.
Importantly, since the inflaton generically produces the gravitinos, those
constraints will turn out to be quite useful to know which models are realized in
nature, especially when the upcoming collider experimental data...

We study cosmological perturbations in two-field inflation, allowing for non-standard
kinetic terms. We calculate analytically the spectra of curvature and isocurvature
modes at Hubble crossing, up to first order in the slow-roll parameters. We also
compute numerically the evolution of the curvature and isocurvature modes from well
within the Hubble radius until the end of inflation. We...

We consider an inhomogeneous preheating scenario in multi-field inflationary
models. There are at least two fields trapped at the ESP after preheating,
one is the inflaton and the other is a ``trapped field'' that plays
important role in generating the curvature perturbation. We consider several
kinds of the potential for the trapped field, which mimics thermal or
quintessential inflation.

We present a chaotic inflation model dominated by the D-term in supergravity.
Our model opens a new branch of model building for inflation.
