Ph.D student at Dept. of Physics, IISc, Bangalore, India. (August 2006 – December 2012)
- Development of pulse sequences for the study of dynamics and order in partially ordered systems and in the solid state.
- Systematic study of cross-polarization (CP) dynamics in the context of 2D-SLF spectroscopy pulse schemes such as PISEMA (Polarization Inversion Spin Exchange at the Magic Angle) and PDLF (Proton Detected Local Field).
- Sensitivity enhancement of 2D-SLF techniques by the incorporation of the ADRF and the ARRF schemes and obtained a gain by a factor of the order of 2 in signal to noise ratio both for solids and liquid crystals.
- The 2D-SLF experiments have been carried out on a variety of liquid crystal systems having different structure and topology.
- The 13C−1H dipolar couplings and 13C chemical shifts derived from these 2D-SLF experiments have been utilized for obtaining the order parameters of various segments of the molecule to get useful insight into the phase behaviour, dynamics and orientation of the molecules.
- Determination of 13C chemical shift anisotropies (CSA) values in the solid state using some of the recent methods like SUPER, ROCSA and utilized the information for the study of the liquid crystalline systems.
- Experience in handling solid state NMR spectrometers like DSX 300, AV III 500, AV III HD 400 WB equipped with various probes including high temperature MAS and static probes, as well as liquid state spectrometer like DRX 500, AV III HD 400.
- Performed and analysed experiments such as PISEMA, PDLF, SAMPI-4, HETCOR and recoupling experiments such as DARR, RFDR, SUPER, ROCSA, MAS based SLF.
- Expertise in writing pulse programs for novel NMR experiments, theoretical interpretations and computer simulations using Matlab, Mathematica computational software.
- Acquaintance with several NMR related software such as SIMPSON, WSOLIDS, DMFIT, matNMR, Bruker Solaguide for NMR spectral simulations.
