Ceremonies held in late September honored four postdoctoral scholars for their outstanding research efforts at JPL. The researchers won a competition at the Labs Postdoctoral Research Day, held August 26. The day showcased the outstanding work of 54 postdoctoral scholars in the fields of Earth science, astrophysics and space science, planetary science and life detection, and advanced technology. The winners delivered lectures on their work at the September 22 awards ceremony and were presented with commemorative plaques by JPL Chief Scientist Dan McCleese. The four winners were:

* An Nguyen (3248) for her work on "Brine rejection and its effects on the Arctic halocline"

* Abigail Allwood (3226) for her research on "Earths oldest biosignatures: A record of microbial activity within 3.45 billion-year-old evaporates"

* Richard Umstaetter (3267) for his work on "Bayesian comparison of approximations of gravitational wave chirp signals"

* Sergey Pereverzev (389B) for "An ultra-sensitive hot-electron nanobolometer"
