Dr. Ozeren has numerous publications on journals and conferences. He is a member of the American Society of Civil Engineers (ASCE), International Association of Hydro-Environment Engineering and Research (IAHR), and AGU (American Geophysical Union) and serves as an officer for the ASCE Hydraulic Measurements Committee.
Dr. Jia joined the National Center for Computational Hydroscience and Engineering, the University of Mississippi, in 1990 as a Post-Doctoral Research Associate. He was promoted to Research Assistant Professor (1994), Associate Professor (2000) and Professor in 2006. In the past twenty years at NCCHE, he has been the major developer of the two and three dimensional computational models: CCHE2D and CCHE3D. These two free surface turbulent flow models have been developed, verified, validated, and refined using many sets of analytical solution, physical model data and widely applied to research and engineering projects. With these models, detailed 3D turbulent flow structures and general flow patterns in channels, lakes, reservoirs, estuaries and around hydraulic structures can be modeled successfully. In addition to free surface flow hydrodynamics, capabilities such as sediment transport, bank erosion, water quality and pollutant transport, etc., are developed in these models. To enhance the efficiency of applications, these capabilities are integrated and operated with a user friendly Graphic User Interface. Dr. Jia has published over 100 technical papers in the areas of computational model development, verification, validation and applications, as well as numerous technical reports of engineering projects. Recently, his research group has extended the capabilities of numerical models to simulate flood associated phenomena, including dam break flows, dam break/levee breaching processes, pollutant transport due to floods, etc. A levee closure simulator has been developed to simulate an engineering practice in an attempt to close a breached levee with sandbags and/or rocks. Dr. Jia retired from NCCHE in June of 2021.

Throughout his time at NCCHE, Mr. Smith has also worked on various projects as DevOps engineer and systems programmer. These projects include the DSS-WISE (Decision Support System for Water Infrastructural Security) Web system, as well as the AIMS (Agricultural Integrated Management System) project.
His research and teaching assistantship over 6 years helped him to become familiar with computational solvers and other software, as well as laboratory experimental equipment setup and operation. He has participated in many physical experiments on spillways, bottom outlets and stilling basins of dams to investigate the flow conditions and related problems that may occur. He also has professional experience with flood inundation analysis.
In 2014, he participated in a project that received Grand Prize from the United Nations Development Programme. For the past 4 years, he has been vice president and instructor in the Turkish Chamber of Civil Engineers (TCCE) Ankara Office Vocational Training Commission.
