Prof. Chris Paola
In 2008, it’s my first time to visit Prof. Chris Paola in the University of Minnesota. Chris is a respectable geologist and a great leader in the discipline of Erth Surface Processes. During the visit, I was so lucky to have contact with Prof. Vaughan Voller and Prof. John Swenson. I also thank Kyle Straub and Matthew Wolinsky for their time to share their wonderful research results to me.
