Chemical and Biological Approaches to the Synthesis and Organization of Inorganic Nanomaterials

I am now in the third and final year of my PhD. My research mainly involves working with microemulsions and proteins as, as outlined below.

Outside of work, I am a member of the Bristol University’s Ballroom and Latin team (ranked third in the country!) and was captain of the team last year. Basically I enjoy anything that keeps me active, such as squash and snowboarding.

Research

Mesoscale Architectures from Nanostructured Building Blocks

Calcium carbonate superstructures are synthesized from water-in-oil microemulsions. Novel morphologies with controlled morphology, polymorph and orientation have been obtained. Most interestingly, SEM studies reveal that at w = 40 (where w = [H2O] / [water]), the resulting product consists of stacked arrays of calcite plates with pseudo-hexagonal morphology (see published paper).

Fabrication of Protein/Silica Core-shell Nanoparticles in Microemulsions

Encapsulation of proteins such as ferritin, within a silica coating using a microemulsion-based synthesis.

Synthesis of calcium carbonate nanoparticles within a protein cage

Apoferritin, the empty protein shell of the iron-storage protein ferritin, is used as a constrained reaction environment for the synthesis of nanoscale particles of calcium carbonate.
