Welcome! My background is applying mathematics to study wave propagation in elastic solids. I work with Surface and plane waves and my work can be found on my google scholar page for reference. Therefore, the research field is some times called as Elastodynamics or solid mechanics. I completed my PhD in the same field from University of Glasgow in 2011. My thesis can be found hereSince then I am affiliated with SNS-NUST. 

The phenomenon of wave propagation in solids has been an area of interest since it is applicable to many real life problems. For example, as mentioned in the book, the manufacturing of high frequency acoustic wave filters and transducers (used in everyday electronic device such as global positioning systems, cell phones, miniature motors, detectors, sensors, etc.), the health monitoring of of elastic structures (non-destructive evaluation in the automotive or aeronautic industry), the acoustic determination of elastic properties of solids (physics, medicine, engineering, etc.), ultrasonic imaging techniques (medicine, oil prospection, etc.), and so on. I would like to work with young researchers on new problems. The theories of linear and non-linear elasticity can be used in problems which involve fluid-solid interaction as well. ​

Research Area:

Solid Mechanics, Elastodynamics, Wave Propagation

Research Interests:

Study of wave properties in residually stressed materials is an saturated field of study in Elastodynamics. Materials are generally considered to be unstressed in their initial configuration. However, practically this is an assumption far from real. The presence of stress in the unloaded state of a material causes major changes in its properties and these changes are studied through the effect of this residual stress on the wave speed, its amplitude and various other parameters.
