Abstract: 

Gravitational lensing is a powerful cosmic tool for exploring a wide range of astrophysical phenomena including understanding how ordinary and dark matter couple and finding the earliest galaxies and stars.  Using Convolutional Neural Networks to sift through legacy imaging data-sets, the AGEL survey confirms about 100 strong gravitational lenses that identify halos spanning a wide range in total mass and cosmological distance.  I provide an overview of the AGEL survey and describe AGEL projects based on observations from the Hubble Space Telescope, Keck Observatory, and the Very Large Telescope.

Bio:

I joined the UNSW faculty in 2017 and have been a professional astronomer for 20+ years. I also was a professor at the University of Zürich and Texas A&M University.  I received my PhD in Astronomy & Astrophysics from the University of California, Santa Cruz and I held postdoctoral fellowships at the Harvard-Smithsonian Center for Astrophysics, Leiden Observatory, and ETH Zürich.  I have given 180+ presentations at universities and conferences around the world
