• Analysis:

Wide experience in statistical analysis of data to extract physical parameters, maximum likelihood fitting techniques, Monte Carlo simulation techniques. more details

• CVD diamond pixel detector development:

Involved in the developing CVD diamond pixel detectors with CMS readout scheme. Made major contribution to build and maintain a silicon strip tracking telescope to test diamond strip and pixel detectors, including associated electronics, hardware and data analysis software. Taking a leading role in the analysis of test beam data to evaluate the performance of diamond detectors.

• CMS Experiment:

A member of the USCMS forward pixel detector group. Participated in evaluating the performance of CMS prototype pixel detectors in beam tests, and analyzing test data. Involved in the design of the Token Bit Manager (TBM) chip of the pixel slow control system. Made significant contribution to the conversion of the TBM in radiation hard 0.25 micron technology.

Designed and built an alignment setup to mount high density and ball grid array integrated circuits. In the process of developing a flip-chip bump bonding system for diamond pixel sensors.

Was involved in the design of a luminosity monitor for the CMS based on CVD diamond pixel detectors, and CMS physics simulation/analysis .

Currently involved in the building of the CMS forward pixel detector, and implementing the pixel detector control system.

• Outreach (QuarkNet-CMS): (2004)

As Rutgers contribution to the QuarkNet high energy physics outreach program, participated in conducting a workshop for high school teachers building scintillation counters to detect cosmic ray muons. Designed developed and built scintillator counters and circuitry to detect cosmic ray muons and to measure muon life time.

• HiRes Fly's Eye Experiment: (2001-2003)

Developed a procedure to calibrate the photo tubes used in the HiRes detector using a hybrid photo detector (HPD) and a roving xenon flasher (RXF) based system. Designed and built test setups and developed the analysis procedure to measure the absolute efficiency of HPDs and to calibrate RXF. Built hardware, and participated in the FLASH test beam experiment to measure air fluorescence light from particle showers generated at the SLAC, FFTB facility.

• CLEO experiment (1996-1999):

Designed and and built the burn-in test setup for the burn-in and calibration of front end RICH electronics for the CLEO III detector upgrade. Also contributed in the design of the beryllium beam pipe and the remote controlled vacuum joint ('magic flange') for the CLEO detector upgrade. Using CLEO data measured the polarizations in B0 -> D*- rho+ and B+ -> D*0 rho decays.

• Fermilab E791 experiment (1992-1995):

Made major contributions to development and testing of offline reconstruction, analysis and simulation software maintained the Monte Carlo simulation software for two years. Participated and made contributions in data analysis and measured the resonant substructure of the decay D0 -> K+K-pi+pi- using an amplitude analysis technique.

• Fermilab E815 (NuTeV) Experiment (1993-1994):

Made significant contributions to the control software of the scintillating detector high voltage system. Built test setups and tested and evaluated scintillator oil used in the upgrade of the calorimeter counters. Participated in test beam studies to test transition radiation detectors used in the experiment.
