Research Interests:
The Fast-Ion-Beam Laser Lab at Western investigates atomic oscillator strengths and Einstein A coefficients, which are essential for determining stellar nucleosynthesis. His work involves studying neutron capture processes (r-process, s-process) and photodisintegration (p-process) in chemically peculiar stars, using experimental techniques to measure atomic lifetimes and transition probabilities.

Laboratory Work:
In the lab, a 10-keV ion beam is excited by a dye laser, and photon emissions are analyzed to calculate atomic data. This research aids astrophysicists in interpreting stellar spectra and understanding element formation in extreme environments like supernovae.
