Degree(s):

  • Ph.D., McGill University

Lab/Center Affiliation(s) (i.e. CoE or SBI):

  • Center of Excellence

Research Interests:

  • Combustion physics and chemistry (chemical kinetics, ignition, flame propagation, extinction, and pollutant formation, turbulent combustion)
  • Applied combustion in gas turbines, internal combustion engines and process burners
  • Fuel technology (formulation, additives and characterization)
  • Thermodynamic analysis of energy systems

Current Research:

Our research interests are in the area of energy conversion, with a special focus on Combustion Physics and Chemistry. Our work is a combination of experiments, combustion theory, and simulations. We determine combustion properties and pollutant formation trends, contribute to detailed and reduced chemical kinetic model development, and use computational fluid dynamics to study turbulence-chemistry interactions in combustion processes.

The ultimate goal is to develop tools for the analysis and design of advanced combustion devices such as gas turbines, internal combustion engines and industrial furnaces. We are also actively involved unravelling the physics of laser-induced initiation of burning processes; an approach that is promising as an alternative reliable ignition source for fuel-flexible engines. Other areas of research include thermodynamic analysis of energy systems and characterization of fuel blends.

  • M.S., Civil Engineering, 1990, University of Texas at Austin, Texas, USA.

  • Durability of wearing surfaces for FRP bridge decks
  • Seismic response of deteriorated concrete bridge components
  • Economy of preventive maintenance of highway bridges
  • GFRP reinforced concrete structures in corrosive environments
  • Smart reinforced concrete structures

Current Research:

Preventive maintenance is the most economical approach to maintain existing concrete bridges. Therefore, evaluation of existing bridges with intention of applying preventive maintenance should be based on chemical assessment of the bridge condition, not primarily based on physical assessment. An in-depth investigation of the combined deterioration effects of various deterioration mechanisms is needed to establish sound thresholds for harmful chemicals in concrete bridge elements. Such established thresholds are critical for cost-effective maintenance decision making, in a timely fashion, before any deterioration starts. This project takes a scientific-practical approach for preventive maintenance of concrete bridges.

Modern, low cost maintenance of concrete bridges using effective NDT test data. This project investigates the smart use of NDT data to predict the near future service condition of concrete bridge components, and its utilization for cost-effective preventive maintenance policy. The impact of this study will enhance the followings: (1) development of better rational for setting maintenance frequency based on condition, (2) development of preventive low-cost maintenance measures for better control of deterioration rate, (3) understanding of financial consequences of delayed maintenance, and (4) reduction of the number of structurally deficient bridges.
