Hauser - Biographical Information

Born in 1958, grew up mostly in Ann Arbor, Michigan. Hobbies were amateur astronomy, photography, and trumpet playing.

Received a B.S. degree in Physics and Astronomy from the University of Michigan in 1979, and received a PhD in 1985 from Caltech. The thesis topic was semileptonic and hadronic decays of charmed meson particles, based on electron-positron annihilations at the Stanford Linear Accelerator Center using the SPEAR accelerator and the Mark III detector (PhD advisor David Hitlin).

Post-graduate work was at the University of Chicago as a Fermi Fellow. Worked with Profs. Frisch and Shochet on the trigger system of the Collider Detector at Fermilab (CDF) experiment, which selected the most interesting of the 1.8 TeV collisions of protons with antiprotons. Then spent one year at the Fermi National Accelerator Laboratory as a Wilson Fellow.

Came to UCLA as an Assistant Professor in 1990. First convenor of the CDF Exotics physics group. Built part of the CDF electromagnetic calorimeter upgrade. Became Associate Professor in 1994 and Full Professor in 1998.

Analysis of CDF data (1989-2008):

• First observation of charmed particles at a hadron collider.
• Charge asymmetry in W boson production (invented the technique and made the first measurement at a hadron collider).
• Searched for anomalous production of jets and missing-energy in a Supersymmetry context.
• Searched for anomalous production of multi-leptons from (e.g.) Supersymmetry, R-parity conserving as well as violating cases.
• Precision mass measurement of the Top quark.

Worked on the Cathode Strip Chamber (CSC) subdetector of the Compact Muon Solenoid (CMS) experiment since late 1994. Designed the CSC trigger algorithm, built some 1600 high-speed programmable electronics boards of various types. Commissioned the electronics in CMS, and now Project Manager of the subdetector at CERN.

Speaks and cooks Chinese reasonable well. Plays the trumpet and the piano (both badly now). Married, with several grown-up children.
