Research

Professor Kaplan’s research concerns multi-wavelength (radio, infrared, optical, X-ray) observations of a variety of types of young neutron stars such as isolated, thermally emitting neutron stars and magnetars. He is also working on detecting radio transients with the Murchison Widefield Array and the Australia Square Kilometre Array Pathfinder

Biographical Sketch

David Kaplan received his Ph.D. in Astrophysics in 2004 from the California Institute of Technology. He was a Pappalardo Fellow in astrophysics at the Massachusetts Institute of Technology Kavli Institute for Astrophysics and Space Research (MKI) from 2004-2007. The following three years Kaplan was a Hubble Postdoctoral Fellow at MKI and at Kavli Institute for Theoretical Physics (KITP) at the University of California, Santa Barbara.

Since 2010, David Kaplan has been at University of Wisconsin-Milwaukee where he holds the rank of Associate Professor. He is also a Visiting Professor at the University of Wisconsin-Madison.

Professor Kaplan is currently Chair of the Murchison Widefield Array Transient Science Team and he is a peer reviewer for several publications, including Astrophysical Journal, Astronomy & Astrophysics, Astrophysical Journal Letters, and Monthly Notices of the Royal Astronomical Society.
