Haocheng Zheng, Ph.D.

After my Ph.D., I worked for the Center for Research and Education on Optics and Lasers (CREOL), University of Central Florida and then as a Senior Optical Engineer for Confluent Photonics Corporation. Since coming to work with Sanford in 2002, we have assembled an evanescent field fluorescent microscope based on total internal reflection, a magnetic tweezers, and a homebuilt laser scanning confocal fluorescence microscope (SCFM). We have submitted a patent on certain parts of operation of the SCFM. I am currently collaborating with Syam Anand, of the Saleem Khan lab, on experiments with helicases. I attended the Paris Summer Physics School in 2005.
