Current and recent research activities:
Aiming at cosmological constraints from galaxy surveys, I work on:
Galaxy cluster detection algorithm and cataloging
Mass measurements via weak lensing for nearby and distant clusters
Weak lensing cosmic shear detection
Photometric redshift catalogs
Deep wide-field survey image analysis software and catalog construction
Strong lensing survey (19 systems discovered so far)
When it comes to hands on data, I explore:
In preparation for future data, I work on:
Integration tests and commissioning of the DES imager, DECam.
Aiming at a theoretical understanding of cosmological gravitational waves, I studied:
The power spectrum of gravitational waves in a dark energy dominated universe.
