Doctoral Candidate - Doctor of Philosophy


Before pursuing my graduate studies, I attained Bachelor of Technology (B.Tech) in Biotechnology from Karunya University, India. Infact my interest towards research began during bachelor thesis work. The project titled " Synthesis of a novel protein from the non-coding region of E.coli genome and its nuclease activity. The work involved purification of protein as well as testing its nuclease activity. 

Further, I have obtained my Master of Technology (M.Tech) in Nanotechnology from Amity University, India. During Master thesis, I have done two projects through which I have gained skills of synthesis of nanomaterials as well as its characterization. Thefirst project was on " synthesis of gold nano rods and its application in heavy metal sensing" where as the second project was on " Synthesis of graphene oxide nanoparticles and its potential application in photocatalysis and water purification". 

Since March 2016, I am a doctoral student at the University of Auckland till present.



Research | Current

My research interest lies in Biophysical chemistry and Bionanotechnology.

The first project involved studying conformational changes, kinetics and thermal stability of PHD2 enzyme upon interactions with CODD or NODD substrates of HIF-α. This work is comprised of PHD2 DNA cloning along with protein expression and its purification as well as synthesis and purification of CODD or NODD peptides. In terms of characterization, I have gained skills in sample preparation, performing experiment and analysis of Small angle X-ray scattering (SAXS)

My current work involves creating and controlling dynamic and reversible bionanostructures of different physical dimensions and different shapes using peptide, boronic acid as building blocks  

Moreover, I am also interested in different characterization techniques especially in optics, instrumentation and sample preparation and  data analysis. Some of the interesting techniques I use for my studies are Light scattering, Small angle X-ray scattering and Small angle neutron scattering, Atomic force microscopy, negative stain and cryo Transmission electron microscopy among others.
