I was PI of the GOODS NICMOS Survey, a 180 orbit Hubble Space Telescope program to image the most massive galaxies in the GOODS fields. This survey explored the deep near infrared universe. We used this data to study the size evolution of galaxies, early galaxy formation, star formation, enviroment and merger histories of galaxies.
I am a co-founder of the CANDELS survey starting in 2009 -- the largest HST program ever to explore the distant universe. My concentration within this survey was to measure the stellar masses of galaxies and their structures and morphologies. The data for this project can be found here.
Palomar Observatory Wide-Field Infrared (POWIR) survey. I led this survey from 2002-2005+ whereby we examined the evoluton of galaxies in a series of deep K-band imaging fields using what was at the time the largest near infrared imager on a large telescope. The DEEP2 autumn and Extended Groth Strip (EGS) data can be found here and here.

In a study based on extragalactic SETI, Tom Westby and I used the Astrobiological Copernican principle to show that there are at least 36 active communicating extragalactic intelligent (CETI) civlizations within our galaxy. The paper for this is here and a blog post of mine explaining the results is here.
In Oct 2016 I released a press release on the number of galaxies in the universe based on one of my papers, explaining that there are 2 Trillion galaxies in the universe -- ten times higher than we previously thought. This was covered in the New York Times, the LA Times, and the Washington Post, among other newspapers around the world. Article it is based on can be read here. This result was the 6th most popular news story in physical sciences in 2016.
I wrote a 2014 review article for Annual Review of Astronomy and Astrophysics on the evolution of galaxy structure. A copy of this review can be found here.
The stellar mass fitting code (SMpy) used in our paper on stellar mass evolution up to z=7 (Duncan et al. 2014) is publically available here.
