Occupation:

I am professor at the Institute of Theoretical Physics and Astrophysics at Xiamen University. My field of research is computational physics, with applications to molecular biophysics and polymer physics, diffusion theory and electronic (atomic) structure. I was also the main programmer of FlexScreen, a software package for computer-aided drug design. Here a list of publications. Teaching: Polymer theory, quantum computation, cosmology, among others.

What I like to do in my spare time:

Doing sports (running, hiking, trekking), traveling around (preferably in Asian countries), shooting photos. From time to time I develop interest in optical equipment, especially cameras and binoculars.

Binoculars news from China

There are lots of mediocre quality binoculars coming from China and swapping the online auctions with ruby-coated plastic crap. However, with open eyes and some patience, it is possible to detect more. In this section I want to present samples that I have found here in China and which perform either far beyond the average or, at least, exhibit some interesting features.
