Research Activities:
As an undergraduate, my first experience in HEP was helping with the
performance evaluation of ATLAS thin gap chambers.  Later I worked on a
new RICH-type of particle ID device, the so-called TOP counter, for the
Belle upgrade.  I undertook R&D on the prototype of this quartz crystal
counter.  On the Belle experiment, I searched for the Lepton Flavor
Violating tau decay, tau -> ell eta/pi0, improving the sensitivity by a
factor of 50.  I also helped maintain the tracking electronics and
hardware. 

At the DZero experiment, I am working on the analysis searching for the
Standard Model Higgs, with WH associated production. I have kept
improving my analysis since 2006 by extending lepton acceptance, 
improving trigger efficiency, and implementing Neural Net and Matrix 
Element technique. So far the limit on the expected cross section has 
been declining almost linearly as the integrated luminosity has increased.  
 I have also been in charge of the Luminosity Monitor operation since 2005. 
To make a stable luminosity measurement, the front end electronics 
has been updated, and the scintillators have been replaced twice during 
this time to deal with radiation damage.
