About me PhD Degree MS Degree BEng Degree Resume

  • This is me...

    Dr Ravi HadimaniI am working on 7 projects in magnetics area of research. Biomagnetism is one of my research interests which has tremendous scope in solving various problems that are related to human health, especially in neurological interventions. I am excited to be working on Transcranial Magnetic Stimulation (TMS) which alters the neuronal functions when time-varying short pulses of magnetic field induce an electric field in the brain. This has been used to treat depression and is currently FDA approved. My lab has developed a TMS coil called the “Halo Coil” that can stimulate deeper parts of the brain non-invasively with greater penetration and less field decay than other coils. This coil has the potential to treat debilitating neurological disorders such as Parkinson'd disease, PTSD and TBI. We are currently developing treatment procedures for these disorders using our novel TMS coils in collaboration with Walter Reed National Military Medical Center and Premier Psychiatric Research Center.
    My bachelor’s degree “ is in Mechanical Engineering and my final year project, Preparation and Testing of Areca Reinforced Plastic Composites” not only yielded a new composite material with better mechanical properties but also, helped the local farmers socio-economically and environmentally. It was during this time I decided that academic research is what I want to do for a living.
    With this enthusiasm and vigour I took up a master’s degree course in Mechatronics at the University of Newcastle, UK. I benefited tremendously from my painstaking work on many research projects in such as design of an intelligent robotic weeder, design of interactive surface using shape memory alloys, etc in this course.

    I have then enrolled for PhD degree at Cardiff University. I was working on Advanced Magnetoelastic and Magnetocaloric Materials for Research Application. I have completed my degree in 3 years.

    For further details on my education and research, please view my resume.

  • PhD Degree from Cardiff University

    I did my PhD on the development of new magnetocaloric materials for magnetic refrigeration.
    During my course I have worked on various magnetic, thermal and electrical properties of Gadolinium Silicon Germanium. I have investigated first order and second order magnetic-structural phase transition in these alloys and developed an advanced technique to estimate second order phase transition temperature when it is suppressed by the first order phase transition. Heat capacity measurements were also carried out at high and low magnetic fields at high and low temperatures.

    I have developed and experimentally verified a model to explain recovery in resistivity due to the annihilation of dislocations in these samples. Single crystal and polycrystalline samples were prepared in collaboration with Ames Laboratory, US and Birmingham University, UK respectively. Various XRD measurements were carried out to determine the lattice structure and I have also carried out back scattered Laue diffraction measurements to determine lattice orientation of the single crystal sample.

    EDUCATION

    2006 - 2009 PhD Cardiff University

    Project title: Advanced Magnetoelastic and Magnetocaloric Materials for Device Applications
    Worked on characterisation of magnetocaloric materials mainly focusing on gadolinium silicon germanium. Magnetic properties such as magnetisation, magnetostriction, magnetoresistance and heat capacity with the variation of magnetic field, temperature, composition and the rotation of the samples were measured. Material preparation was carried out in collaboration with Ames Laboratory, US and Birmingham University, UK.
    As a part of the study, an advanced technique to estimate the second order phase transition temperature of the materials when it is suppressed by a first order magnetic- structural transition is developed. A model to explain the recovery in the resistivity when it passed through first order phase transition was developed.
