It also provides sensitivity to neutrinoless double-beta decay, a process that violates number conservation. Our group is involved in many aspects of the LZ experiment, from detector calibration, simulations to data analysis.</p> <p> </p> <p>The successful candidate will play an active role in analyzing LZ data, with opportunities to improve simulation models used in rare-event searches, develop machine learning methods for background rejection, and place constraints on new physics using LZ datasets.</p> <p> </p> <p>In addition, the postdoc will lead the development of a dedicated testbed to advance dark matter detection technologies. This work will involve close collaboration with the PI and technical staff to design, build, and operate a particle detector within a cryogenic system, evaluate photosensor performance beyond commercially rated specifications, and calibrate the detector response.</p></div></div><div style="padding:10.0px 0.0px;border:1.0px solid transparent"><div style="font-size:16.0px;word-wrap:break-word"><H2 style="font-size:1.0em;margin:0.0px"><b>Application Information</b></H2> </div><div><p>The position is available for a flexible start date as early as May 1, 2026.
