About myself: I am currently a Senior Research Officer in the Organic Chemical Metrology group in the Metrology Research Centre of the National Research Council Canada in Ottawa. Please check my ORCID iD iconORCID profile.

About my research: I develop solid-state NMR techniques for quantitative analysis (qNMR) and to characterize advanced materials in emerging technologies across a wide range of natural and synthetic advanced materials. These materials include natural and synthetic nano- and mesoporous materials for gas sequestration and storage such as gas hydrates, minerals, aluminates and zeolites, quantum dots for light harvesting, modern battery materials, fuel cell membranes, various hydrides for hydrogen storage applications, modern pharmaceutical compounds and polymers.

Please don't hesitate to contact me with your specific materials characterization problem, or if you would like to work with me as co-op, summer student or visitor.

Our paper entitled “Insight into the Chromophore of Rhodopsin and its Meta II Photointermediate by 19F Solid-State NMR and Chemical Shift Tensor Calculations” has been accepted for publication in Physical Chemistry Chemical Physics.

19F solid-state NMR studies together with bond polarization theory chemical shift tensor calculations provide insight into the chromophore of rhodopsin and its active state Meta II.

Our paper entitled “Quantification and stability of surface amine groups on silica nanoparticles using solution NMR” has been accepted for publication in Analytical Chemistry.

We have developed an optimized protocol for dissolution of aminated silicas and determined functional group content by quantitative 1H NMR (qNMR) of the released amines.

Our paper entitled “Capturing Elusive Polymorphs of Curcumin: A Structural Characterization and Computational Study” has been published in Crystal Growth & Design.

Two polymorphs of curcumin (monoclinic and orthorhombic forms) were obtained and characterized. The crystal structure of the orthorhombic form was redetermined and 13C and 1H solid-state NMR spectra assigned, based on the 2D 13C–1H HETCOR nuclear magnetic resonance experiment and GIPAW density functional theory calculations. We demonstrate the importance of combined experimental and computational approach in the characterization of polymorphs in bulk samples.

My paper entitled “Introduction to Average Hamiltonian Theory. I. Basics” has been published in the special issue of Concepts in Magnetic Resonance in honor of Alex Bain.

The goal of this paper is to introduce average Hamiltonian theory in a rigorous but educational manner. The application to two composite pulses in NMR spectroscopy is used to demonstrate important aspects of average Hamiltonian theory.
