BIOGRAPHY

 

Description

My research focuses on a class of materials called ferroics. Ferroics are so-called “functional materials” used for applications such as computer memory, sensors and medical imaging etc. Our group spends hours trying make these ferroics at very tiny dimensions and to see what happens when ferroics are scaled down to the size of a few nanometers. The challenge is not only in making them but also seeing these nanostructures and measuring their properties. At such length scales, the background noise often overrides the signal of interest. In materials science lingo we call this the synthesis-processing-characterization triangle…

Education

  • PhD in Materials Science and Engineering (University of Maryland, 2001)
  • Bach. Engg in Metallurgy, 1997 (University of Pune)

 

RESEARCH

 

My Research Goals

  • Ultra-thin ferroics
  • Interface effects in metal oxide nanostructures
  • Thin film epitaxy
  • Scanning probe microscopy of functional materials

My Research in Detail

In our group we are interested in the properties of a material at an interface. In fact often the system of interest is so small that the surface area dominates over the volume – we called this surface and interface mediated phenomena. We study interface morphology, chemistry and structure and its effect ultimately on the properties.

Current Student Projects (PhD and Honours)

1. Interface effects in ferroelectric/multiferroic thin films

2. Oxide nanocrystals for chemical sensing and resistive switching applications

3. Solid state dewetting of metallic thin films

Supervision Opportunities/Areas

I am always looking for prospective students interested in nanomaterials and interface/surface phenomena. For projects please write to me. I do read and reply to emails from students….

Advice for prospective students

Our lab thrives on research excellence. This means there is always high pressure to publish in leading journals. All students thus have to develop a sense of humour and a thick skin to survive the lab. In depth knowledge of Monty Python and other classic comedy is an added advantage. Of course we get to do visit international labs, conferences and workshops. Our international collaborators come from leading labs in the US, Europe and Asia-Pacific region, and often students combine visits to collaborator labs with a conference.
