Biography

I am a staff scientist with expertise on laser development, laser ion sources,  and ultra sensitive methods for resoance ionizationation spectroscopy and mass measurements.

Research interests

My research contributes to the knowledge on the nuclear ground state properties of exotic nuclei, particularly in the immediate region near tin-100. In my research I utilize highly efficient and selective laser ion source coupled with a Penning trap or MR-ToF mass spectrometers to enable ultra-sensitive in-source resonance ionization spectroscopy and high-precision mass measurements. I am also involved in developing resonance ionization spectroscopy methods to bring very sensitive high-resolution laser spectroscopy capability to our laboratory.
