Welcome three outstanding visiting scholars to join our research group. They will stay at Texas A&M University for a year. Dr. Yun-an Li is a Professor of Geotechnical Engineering from China University of Geosicences (Wuhan). He is working on Groundwater Flow to Deep Tunnels; Mr. Guangyao Gao is a PhD candidate from China Agricultural University. He is working on Contaminant Tranpsport Using the Mobile-Immobile Apporach; Mr. Zhang Wen is a PhD candidte from China Agricultural University as well. He is working on Non-Darcian Flow in Fractured and Porous Media.

Hello, welcome to Hongbin Zhan's web page. My teaching and research interests cover various topics of groundwater hydrology and contaminant transport. Both theoretical and experimental approaches are used in our research projects. I am recently interested in (1) Dynamics of horizontal wells and its applications in hydrosciences and environmental engineering; (2) Aquitard control on flow and transport; (3) Non-Darcian flow in porous and fractured media and its impact on transport; (4) Stream-aquifer interaction. It is fun to study hydrology!

For many years, I am inspired by Prof. Richard Feynman's view of science (1918-1988) as follows: "What do we mean by "understanding" something? We can imagine that this complicated array of moving things which constitutes "the world" is something like a great chess game being played by the gods, and we are observers of the game. We do not know what the rules of the game are; all we are allowed to do is to watch the playing. Of course, if we watch long enough, we may eventually catch on to a few of the rules."

Prof. Feynman's explanation of nature: God made the laws only nearly symmetrical so that we should not be jealous of His perfection.
