Curriculum Vitae:

Calen Henderson

Hello! I am an NPP Fellow who specializes in using the gravitational microlensing technique to search for and characterize exoplanets toward the Bulge of our Milky Way Galaxy. For my Astronomy PhD at The Ohio State University I constructed simulations to optimize the observing strategy for and predict the planet detection rates of the Korean Microlensing Telescope Network (KMTNet), which consists of three ground-based survey telescopes dedicated to monitoring the Bulge to detect planets via microlensing.

At JPL I join a vibrant microlensing group that focuses on maximizing the scientific yield from space telescopes that conduct microlensing observations simultaneously with ground-based resources. Specifically I am analyzing results from a recent campaign using the Spitzer space telescope and K2's Campaign 9 (K2C9) as well as WFIRST. I have furthermore helped create a high-resolution follow-up group that uses Keck to directly measure the fundamental parameters of microlensing systems via a method that is orthogonal but complementary to space-based microlensing endeavors.

I am also an avid runner and cyclist as well as a classically trained pianist and would love to discuss any of these things in more detail!
