My students and I use radio telescopes to study pulsars—rapidly rotating neutron stars— for a variety of purposes, including the detection and characterization of long-wavelength gravitational waves. Much of this work is done as part of the NANOGrav Physics Frontiers Center. Our work is supported by the National Science Foundation.
A nice article on recent NANOGrav collaboration work is here:
Cosmic Ringtones in Pulsar Data? (APS news)
We were frequent users of the Arecibo Observatory. Unfortunately, after a series of cable failures, the observatory structure collapsed in December 2020. Despite this, pulsar research at Lafayette remains strong using other observatories, such as the Green Bank Telescope.
Personal: My wife, Marian Wentworth, is CEO of Management Sciences for Health, a global nonprofit organization that works with communities and governments to strengthen health systems serving the world’s most vulnerable populations. We have two daughters, one working in public education policy research and advocacy, the other a graduate student in math, both ballet dancers in their spare time.
