physics analysis
• I was strongly involved in the analysis for the paper “Search for Leptoquarks with
the ZEUS Detector” (Phys. Lett. B306, 173 (1993)). Later leptoquark search
analyses which I’ve done have been presented at conferences.
• I performed the second analysis and was an author <strong>of</strong> the paper “Measurement <strong>of</strong>
Charged and Neutral Current ep Deep Inelastic Scattering Cross Sections at High
Q 2 ” (Phys. Rev. Lett. 75, 1006 (1995)).
• I performed the second analysis and was an author <strong>of</strong> the paper “Study <strong>of</strong> Charged-
Current ep Interactions at Q 2 > 200 GeV 2 with the ZEUS Detector at HERA”
(Z. Phys. C72, 47 (1996)).
• I performed the primary analysis and was an author <strong>of</strong> the paper “Search for Lepton
Flavor Violation in ep Collisions at 300 GeV Center <strong>of</strong> Mass Energy” (Z. Phys. C73,

613 (1997)).
• I performed the primary analysis and was an author <strong>of</strong> the paper “Comparison <strong>of</strong>
ZEUS Data with Standard Model Predictions for e + p → e + X Scattering at High
x and Q 2 ” (Z. Phys. C74, 207 (1997)).
• Since 1999, I have been developing an analysis to search for R-parity violating
supersymmetry. In March <strong>of</strong> 1999, I gave a talk on an early version <strong>of</strong> the analysis
at the Higgs and Supersymmetry conference (Gainsville, Florida) and in June <strong>of</strong>
2000, I gave a talk on an improved version <strong>of</strong> the analysis at the SUSY2K conference
at CERN. A paper on the analysis was submitted to the Osaka conference (paper
no. 456).
• I performed the statistical analysis for an excited fermion search which included a
full treatment <strong>of</strong> the natural width (hep-ex/0109018). The paper will appear in
Physics Letters B.
• I performed the primary analysis <strong>of</strong> multi-electron states for the paper “Study <strong>of</strong>
multi-lepton production with the ZEUS detector at HERA” which was submitted
to the ICHEP 2002 conference (Amsterdam). The analysis is being finalized for
publication.
physics coordinator
From 9/93 to 9/96 I was the deputy coordinator and from 9/96 to 9/97, I was the
coordinator <strong>of</strong> the High Q 2 /Exotic Physics Group. From 9/2000 to 9/2002, I was a
coordinator <strong>of</strong> the Exotic physics group. In addition to reviewing and supervising physics
analyses within the group, I have been strongly involved in writing and editing papers
based on these analyses.
ZEUS analysis coordinator
Since 10/2002 I have been the ZEUS analysis coordinator. Most ZEUS physics analysis
is now performed in a standard analysis framework. I am responsible for maintaining
the analysis code, integrating new analysis code, and providing a user-friendly and welldocumented
environment. This job involves interaction with all ZEUS physics groups.
reconstruction s<strong>of</strong>tware
• I wrote and have maintained the <strong>of</strong>fline data selection for the High Q 2 /Exotic
Physics group.
• I developed the electron identification algorithm used by ZEUS for high-Q 2 Neutral
Current cross section analyses and also for exotic searches. The algorithm is based
on a multi-dimensional likelihood which uses information from the calorimeter and
the tracking detector.
• I developed optimization s<strong>of</strong>tware which used Neutral Current data to determine

the following properties <strong>of</strong> the barrel calorimeter: the electromagnetic energy scale;
the position; the orientation; parameters describing the spatial and angular nonuniformity
<strong>of</strong> the calorimeter response. I provided ZEUS with code to calculate
non-uniformity and energy scale corrections for electrons in the barrel calorimeter,
resulting in improved energy resolution. The optimization procedure also determined
the momentum resolution <strong>of</strong> the Central Tracking Detector for isolated
tracks.
• I determined the response <strong>of</strong> the calorimeter to hadronic jets and the dependence
on jet energy, angle, and electromagnetic fraction.
trigger
• I designed trigger level cuts on calorimeter timing used to reject non-ep backgrounds.
I developed and implemented trigger algorithms for high Q 2 charged
current and neutral current scattering and also for other high Et processes. I have
been active in maintenance and development <strong>of</strong> these triggers.
• ZEUS is commissioning a new tracking trigger using the Central Tracking Detector
and the Micro-Vertex Detector. I wrote an interface between this trigger and the
geometry data base which describes the detector.
supervision <strong>of</strong> students
Both as a member <strong>of</strong> the Columbia group, and as a coordinator <strong>of</strong> the High Q 2 /Exotic
physics group, I have worked extensively with Ph.D. students who have written thesis on
high Q 2 charged current and neutral current cross sections, as well as searches for leptoquarks,
lepton flavor violation, excited fermions, supersymmetry, and heavy neutrinos.
shift leader
Since 1996 I have been a shift leader during all data taking periods except for 1998.
referee
I have refereed papers from major collider experiments for Physical Review Letters,
Physical Review D, and European Journal <strong>of</strong> Physics C.
computer system manager
Since 2001, I have been the compter system manager for the U.S. ZEUS group. I’m
responsible for maintaing about 15 Linux PCs including installation <strong>of</strong> hardware and
s<strong>of</strong>tware, ordering new equipment.

<strong>Experience</strong> on Fermilab E605
1/83 – 9/90: Research Assistant, University <strong>of</strong> Washington.
10-12/90: Consultant, State University <strong>of</strong> New York at Stony Brook.
4-5/91: Visiting Scientist, University <strong>of</strong> Washington.
• I worked on the 1984 and 1985 runs <strong>of</strong> Fermilab experiment 605. The purpose <strong>of</strong>
E605 was to study production <strong>of</strong> high-pt hadrons and high-mass hadron and lepton
pairs. I was involved in detector commissioning, wrote online detector monitoring
s<strong>of</strong>tware, worked on <strong>of</strong>fline detector studies and served as code manager for the
collaboration. I worked on all aspects <strong>of</strong> data analysis for 1984 run including pattern
recognition and fitting <strong>of</strong> tracks, trigger efficiencies, determination <strong>of</strong> calorimeter
energy scale and resolution. My analysis concentrated on the data from the ring
imaging Cherenkov detector, which was the first ever to operate. This involved
time-dependent calibrations <strong>of</strong> the the radiator gas index <strong>of</strong> refraction and the
focusing mirror positions. My thesis covered A-dependence, particle fractions, and
cross sections for single hadrons and for hadron pairs.
• I wrote a paper (Phys. Rev. Lett. 68, 452 (1992)) based on my thesis research
covering A-dependence <strong>of</strong> high-pt hadron and high-mass hadron pair production in
pA collisions at √ s <strong>of</strong> 38.8 GeV.
• I wrote a paper (Phys. Rev. D45, 3030 (1992)) based on my thesis research on
the relative abundances <strong>of</strong> high-pt π’s, K’s and protons, and species correlations
between opposite-side high-pt hadrons in pA collisions at √ s <strong>of</strong> 38.8 GeV.
Other <strong>Experience</strong>
9/81 – 6/83: Teaching Assistant, University <strong>of</strong> Washington.
Set up and helped students perform atomic, nuclear and low-temperature experiments.
6/80 – 7/81: Programmer, M.I.T. Lab for Nuclear Science, Cambridge, MA.
Worked on automated pattern recognition <strong>of</strong> bubble chamber photographs.
1/78 – 1/79: Programmer, GRI Computer Inc., Newton, MA.
