Biography

After graduating from ETH Zürich, Switzerland with minors in geo– and astrophysics, I turned to neutrino physics and obtained a PhD from Neuch?tel University. In 1997 I received a Young Researcher Grant from the Swiss National Science Foundation to move to Canada and work on the SNO project, then in construction. After a postdoctoral fellowship with Carleton University, Ottawa, I was appointed assistant professor at 黑料吃瓜不打烊 in 2001. This was a very exciting year with the first SNO results! My contributions to SNO focused on the monitoring of ultralow levels of radoactivity in the water systems. I also led SNO's Low Energy Backgrounds Analysis Group. I have since pushed the sensitivity of the radon detectors used for SNO to support new initiatives with more stringent background requirements.

In 2002?I participated to the CFI proposal and helped?establish?SNOLAB; my main contribution was the design of the surface building.

I joined the Enriched Xenon Observatory Collaboration (EXO) in 2004. EXO is aiming at an absolute measurement of the neutrino mass scale with the discovery of neutrinoless double-beta decay of 136Xe -- if the transition exists. In June 2012 we published our first results from EXO–200?and had then?the best world limit on the effective neutrino mass. With this analysis, we have also essentially ruled out an earlier claim for discovery in 76Ge. My contributions to EXO include the calibration system, radon mitigation and radon production assessments. The collaboration is very active now?preparing for nEXO.

Since 2006 I contribute to the direct search for dark matter with PICASSO, then PICO. My interests, like in SNO and EXO are with the understanding and improvement of backgrounds. Since 2007 I am also a collaborator of HALO, a SNOLAB based detector of supernova neutrinos.

An avid caver, I have published frequently in spelunking journals and coordinate the survey of the Motiers Cave near Neuch?tel, Switzerland -- the second longest in the Canton.

Research

My research interests are in neutrino physics and the search for dark matter with a focus on low background techniques. I am very excited about the potential for discovery of neutrinoless double beta decay by nEXO;?the direct observation of dark matter using superheated liquids with PICO;?and the live detection of supernova neutrinos with the HALO detectors.

Current research activities:

- radon emanation at the level of <5 atoms/day (material screening; 222Rn, 220Rn, 219Rn)

- development of higher sensitivity radon counters

- radon mitigation in xenon (radon removal, emanation suppression)

- development of external calibration sources for nEXO

- gamma spectroscopy with 400cc Germanium detector (material screening)
