Dr. Umananda Bhatta obtained his Ph.D in Physics from Institute of Physics (IOP), Bhubaneswar affiliated to Homi Bhabha National Institute (DAE undertaking). During his Ph.D he was instrumental in developing in-situ heating facility at IOP, Bhubaneswar, during which period he did an extensive study on temperature dependent behaviour of Au thin films on various Si substrates. After completing his PhD, he got selected to work on an Engineering and Physical Sciences Research Council (EPSRC), UK project, and undertook his postdoctoral research at the Department of Materials and Engineering, University of Sheffield from 2010 to 2013. During this time, he worked on a project titled, “Building Ceramic Metamaterials from Nanoparticles: A combined Modeling, Tomography and In-situ Loading Study” a part of EPSRC project which involved collaborations with several other distinguished Universities from UK and USA. During his postdoctoral stint, he played a key role in studying the surface properties of ceramic nanomaterials using advanced electron microscopy techniques, including Aberration Corrected Microscopy, Nanotomograpy, Electron Energy Loss Spectroscopy (EELS) and Nano indentation among others. His major specialization include, Advanced Electron Microscopy and associated techniques and has vast experience in other domains of experimental surface physics including X ray diffraction, X-ray Photoelectron Spectroscopy, Ion Beam Synthesis and Characterization. His main research interests include, studying Interactions at surfaces/interfaces of different nanomaterials/hetero epitaxial thin films, Ion beam synthesis (IBA) and characterization and in-situ thermal and mechanical studies of nanomaterials.
