The evolution of advance materials should be accompanied with successful manufacturing processes such as joining.  My research concerns the joining technology of dissimilar materials relating the process of joining to the properties of materials.  Currently, I have two directions to proceed with innovative joining processing.  First direction is to use Spark Plasma Sintering technology (SPS) to bond dissimilar materials and furthermore to produce interesting bulk composites from nanosized powders. The second direction of my research is using Femtosecond Laser technology (FSL) to perform micro and nanojoining of nanostructured materials and also to perform surface modifications of selected materials for various applications from sensing to bioimplants.  The FSL applications extends to the area of micro-scale 3D printing.  The modelling of joining processing especially the SPS process is done by finite elements.  In term of characterization techniques, we have extended experience related to surface analysis such as XPS and UPS along with XRD, SEM/EDS and Raman Spectroscopy.
