1. PROFESSIONAL CHRONOLOGY

I am an assistant professor of geological/environmental engineering and GIS/Remote sensing application in the Department of Geology at Sohag University since November 2004. I got a B.S. and a MS. in geology from the South Valley University (Sohag Branch), Egypt in 1992 and 1998, respectively. I got a second MS. in Civil Engineering (Geotechnical Engineering) and a Ph.D. Geological Engineering from University of Missouri-Rolla (Currently Missouri University of Science and Technology), USA, in 2004

----------------------------------------------------------------------------------------

2. RESEARCH INTEREST

My research interests focus on two major areas: 1) Geological/Environmental/Civil engineering and 2) Remote sensing and GIS. As a Geological engineering, I am interested in all aspects regarding application of engineering theory to solve geological, environmental, and geomorphological problems. As well as, the application of Remote Sensing and GIS in geological and structural mapping; environmental engineering; landslides; rock slope stability; database management systems; solid and liquid wastes disposal sites; sustainable development; statistical analysis applications in engineering geology; and geo-environmental hazards.

 

I enjoy geological/environmental engineering because I am curios about geological and environmental problems and using engineering theory with the help of remote sensing and GIS to solve them. It gives me a good chance to travel to remote places and examine the Earth.
