Research Interests
I am interested in phase transformations and microstructural evolution
during processing of metallic alloys. In particular, welding and
solidification processing has been one of my core research focus.
Collaborating with colleagues, we have also started to look at
phase transformations in other kinds of processing operations and systems
such as thin films. Using structural characterization tools (mostly electron microscopy
and associated tools, X-ray diffraction, DSC/DTA,etc.), we try to gain insight into
liquid to solid and solid state phase transformations, and in turn, and relate
them to the microstructure and properties. We also develop computational models
which can help us understand the macroscopic transport at one end and
microstructure formation on the other. The grand challenge, of course,
remains to link these together in a satisfactory fashion.
