I worked on the CLEO electron positron collider experiment for my Ph. D. thesis work. First 3 years of my graduate work on CLEO was spent on building the CLEO III CsI End Cap calorimeters, from the mechanical/electronics design to the commissioning phase. It is so far the biggest hardware project of my scientific life. I also had worked on the monitoring and readout electronics of the End Cap calorimeters.

For analysis, I was a lone ranger, working alone on two-photon fusion physics, doing analysis from search for charmonium states to anti-search for glueballs. All my analysis projects ended up on PRL!
