About Me

I am an astronomer at Steward Observatory at University of Arizona. I’m a member of the JWST NIRCam Science Team, and I helped with testing and commissioning the primary camera on board the observatory. My research explores the ultra high redshift universe, supermassive black holes and their host galaxies, and infrared selection of cold brown dwarfs. I am also an advocate for science outreach education. I’m very enthusiastic.

My Research

Prior to the launch of JWST, my primary focus was optical and infrared observations of obscured active galactic nuclei, or AGNs. I helped identify new obscured sources using the Wide Field Infrared Survey Explorer, or WISE, telescope. I also helped uncover the physical extent of the narrow-line regions for local obscured quasars.

Since moving to the University of Arizona, I worked to support JWST NIRCam. My research focuses on exploring sources in the JWST Advanced Deep Extragalactic Survey, or JADES. I have helped identify some of the farthest galaxies humans have ever seen, stretching back to a redshift of 14. I’ve also explored how JWST NIRCam can find low-temperature brown dwarfs in our galaxy.

I have a passion for science outreach education, and I’ve worked with many local and national schools and outreach groups. I’m an active member of Skype A Scientist, where you can have me virtually speak with your students about astronomy and the Universe!
