Selected Works of Zhongmei Yao

Associate Professor

I am an Assistant Professor in the Department of Computer Science. My passion for teaching and research led me to join UD in Fall 2009 after receiving my Ph.D from Texas A&M University. I truly enjoy programming computers. I like the complexity involved with technology and being able to conduct extensive research in this area.
