Amer Hmidan - Structural Emphasis
Research Area
By way of finite element modeling and experimental testing the interaction between CFRP (Carbon Fiber Reinforced Polymer) sheets and concrete/steel beams is being investigated. Effects of fatigue loading and temperature susceptibility are under investigation as to their contribution to deterioration effects.

Dalu Zhang - Environmental Emphasis
Research Area
My research is focused on materials and methods that improve the durability of concrete pavements. This includes the experiments design to evaluate the factors that affect the durability of concrete pavements. The outcomes of the research will provide sustainable solutions to concrete durability problems in roads, highways, and airport pavements.

Research Area
Analysis of drought impact and severity using derived indices based on U.S. Drought Monitor data. Application of Geographical Information System (GIS) and Remote Sensing technique to validate the indices and display spatio-temporal variations of drought respectively. Study of drought–yield relationship using derived indices and county wide yield data.

Mohy El Din Ragab - Environmental Emphasis
Mohy El Din RagabResearch Area
The utilization of recycled materials in flexible asphalt pavement is a way to sustainable development. Our research work is focused towards the employment of recycled scrap tires known as crumb rubber modifier (CRM) in the modification of asphalt. Through this approach, we save the environment by using scrap tires that were supposed to be land filled. In addition, we obtain comparable properties to those of asphalt virgin modifiers by controlling the interaction conditions between asphalt and CRM.

Chunju Gu - Material Science and Nanotechnology Emphasis
S.ShanbhogueResearch Area
Fundamental study of the molecular interactions between different constituents of nanocomposite materials such as polymer clay nanocomposites and natural bones with the aid of spectroscopy, and relate them to nanomechanical properties of these materials.

Dhritikshama Roy - Environmental Emphasis
Research Area
Polydimethylsiloxane and other polymers are used in surface modification of nanoparticles for environmental remediation. Low molecular PDMS are biodegradable in a particular soil moisture condition; however, high molecular PDMS are non-biodegradable in both soil and water. Biodegradation of PDMS is tested for the research using both pure and mix microbial consortium. Work is also being done on the nitrification of ammonia oxidizing archaea (AOA).

Ehab Noureldin - Pavement Materials
Research Area
As it is important to retain virgin aggregates for the future generations and in the same time to reuse the waste materials generated from the pavement industry in an useful way to our environment. My research work in this area is related to utilizing Recycled Asphalt Pavement (RAP) in the base layer of the pavement cross-section. The base layer in the flexible pavements is the main component that is responsible on carrying the loads of traffic and increasing the structural capacity of this layer leading to a longer life time for the pavement.

Yaping Chi - Water Resources / Hydrology Emphasis
Research Area
My current research focuses on "combined experimental and modeling study on overland flow generation”. Specifically, I characterize surface microtopography using different methods, do the experiments on microtopography controlled overland flow generation, and compare the experimental results with the simulated results by applying the P2P (puddle to puddle) modeling system.

Garrett Brunell - Structural Emphasis
Garrett Brunell Research Area
Both computer modeling with finite element analysis and experimental testing are being performed for structural rehabilitation of steel beams and trusses retrofit with composite materials. Two areas of research include; CFRP (carbon fiber reinforced polymer) sheets used for flexural strengthening of wide-flange beams and post-tensioned CFRP rods for rehabilitating damaged steel trusses.

Daniel Bogart - Water Resources / Hydrology Emphasis
Research Area
Work is being performed on the effect of microtopography on the characterization of the hydrograph. Improved models of the partition between infiltration and runoff generation, flow path delineation and sink filling have given way to better accuracy in predicting hydrographs at the watershed's outlet. This study involves a scaled down look into the microcosm that is small depressions in their effect on the time to ponding, time of concentration and total excess rainfall.
