Researcher and scientific writer in molecular magnetism with 8+ years of experience

Profile Summary

I completed my PhD from IIT Bombay, India in November 2016 and I have three years of postdoctoral experience. I mainly research in the area of synthesis and molecular modelling of transition metal and lanthanide based coordination complexes as Single-Molecule Magnets (SMMs)/Single-Molecule Toroics (SMTs). I synthesized various transition metal, mixed 3d-4f and lanthanide complexes. I am an expert in characterizing those metal complexes using single crystal X-ray diffraction method, IR and SQUID magnetometry and study their electronic and magnetic properties using both DFT and ab initio calculations.
