Sherif Farouk is a Professor at the Exploration Department of the Egyptian Petroleum Research Institute, Cairo. He gained his PhD from Al-Azhar University, Egypt. He worked with the Geological Survey of Egypt from 1996 to 2007, gaining a wide field experience in sedimentary rocks of the Middle East, including high-resolution stratigraphy and accurate paleontological applications. Sherif has published about 166 scientific research articles in many international journals of the Phanerozoic stratigraphy, especially in Egypt, Jordan, Saudi Arabia, Iraq, Emirate, and Tunisia. My fields of research are Litho-biostratigraphy, palaeoenvironmental analysis, and sequence stratigraphic studies, as well as the ability to solve many geological problems such as picking formation tops, lateral and vertical changes in facies and thickness, production zone identification, and integrating the sedimentary data with geophysics and tectonics.
