Bio: My research is developing liquid xenon detectors for particle astrophysics experiments. My group focuses on the direct detection of dark matter and the search for neutrinoless double beta decay. As a member of the XENON100, XENON1T, XENONnT, and DARWIN dark matter experiments, and also the nEXO neutrinoless double beta decay experiment, my research focuses on development of techniques for operating high purity xenon detectors, including purification and diagnostics, as well as novel radiopure electrodes based on thin films. My group also works on simulations and data analysis looking for new physics with these experiments.

B.Sc. Physics, Rensselaer Polytechnic Institute, Troy, NY, 2013
Bio: I'm currently a second year Ph.D student in Physics. As an undergraduate I participated in work on the Daya Bay Neutrino Experiment involving the use of background cosmic radiation to measure the clarity of the water in the water shields of the neutrino detectors, and hence the efficiency of the muon veto system. For my M.Sc. I oversaw a target arm upgrade of the PREX-II Moller Polarimeter, from mechanical design to production and installation. I also performed an analysis of spectrometer beam optics to understand the requirements for a precise measurement of electron beam polarization. My Current work is for the XENON Dark Matter Experiment.  I'm currently responsible for the design, simulation, production, and testing of a Gas Purity Monitor that will be installed at various points throughout the XENON1T purification system to help ensure adequate performance of various system components.  I'm also performing an analysis of  $^{83m}Kr$ in an effort to utilize the $9.4\ keV$ electron to characterize the detector in the region of the electron recoil band where we expect a dark matter signal.

Bio: I am a first year graduate student in the physics program, and just recently joined the nEXO collaboration. In my undergraduate career I competed in mathematical modelling competitions and completed a senior project on computational simulations of surface gravity waves on a circular fluid-fluid interface with varying conditions. There are many topics I'm beginning to investigate with regards to the nEXO experiment and high purity liquid xenon.

## Master’s Students

Name: Daniel Alexander
Position: Co-Terminal M.Sc. Student
Bio I am currently a Junior in the B.Sc./M.Sc. co-terminal program in Physics. As a member of the XeRPI group since 2014, I've been working mainly on developing laboratory infrastructure, including the design and construction of a gas distribution system to direct and control high-purity xenon to various experiments in the lab. I'm also beginning to investigate the physics of the $^{83m}Kr$ decay via internal conversion, and how it applies to the half-life measurement of the $7/2^{+}$ first excited state.
