Stellar variability and distance indicators in the near-infrared in nearby galaxies
Multi-wavelength photometric variability in globular clusters in the Milky Way and LMC
Abundance measurements of pulsating variable stars based on high-resolution spectroscopy
Stellar evolution and pulsation modeling - Cepheid and RR Lyrae variables
Morphology and structure of Milky Way and nearby galaxies as traced by their variable stars
Structure and kinematics of stellar populations in the Galactic bulge
Observational datasets for these projects are available from PI/Co-I programs on the state-of-the-art 4-8m class telescopes : HAWKI@VLT, UVES@VLT, Gemini-F2, WIRCam/MegaCam@CFHT, OmegaCam@VST and large time-domain astronomical surveys (Gaia, TESS, ZTF etc.) Access to stellar evolution and pulsation models is through collaborations and using open-source MESA 1-D stellar evolution code
These projects are design to contribute to the broader research interests in precision cosmological distance scale, Galactic archaeology and near-field cosmology, and stellar evolution and pulsation theory.
