According to his page on the website of UTMB, Prof. Zou Zhihua completed his BS and MS degree in First Military Medical University (now known as Southern Medical University), Guangzhou, China in 1986. He then went on PhD study in Osaka University, Japan from 1992 to 1997, followed by post-doctoral training in Havard University. His research interests include:

• Identification of functional neural circuits
• Odor and pheromone sensing
• Neural and Metabolic Control of Food Intake and Metabolism

He listed three publications under his page, he being the first or second author, with L. Buck being the last:

• Zou, Z. and Buck, L. Combinatorial Effects of Odorant Mixes in Olfactory Cortex. Science 311, 1477-1481, 2006
• Boehm, U., Zou, Z., and Buck, L. Feedback loops link odor and pheromone signaling with reproduction. Cell 123(4): 683-695, Nov. 18, 2005
• Zou, Z., Li, F., Buck, L. Odor maps in the olfactory cortex. Proc Natl Acad Sci USA 102 (21), 7724-7729, 2005

It is shown on the Science abstract page of the first paper that it has been retracted, with the retraction announcement by L. Buck published on the same journal on Sep. 24, 2010, the reason being failure to reproduce the result.

Nature News reported this event, in which the reporter mentioned:

Zou returned to his native China in July 2009, leaving no forwarding address, says the administrator. He could not be reached for comment.

I think the information I provided above may help the reporters reaching Prof. Zou for comment.
