I am currently a Research Associate in Nanomaterials at Queen's School of Engineering, University of Bristol.  Before that, I was a CDT PhD student at the Centre for Sustainable Chemical Technologies, at the University of Bath (2014-2016) and completed my PhD at the University of Bristol (2016-2019) with a background in Chemical Engineering.


My research is about designing new nanomaterials which have hierarchical porous structures. The artificial porosity in these materials is tailored for improved energy storage, drug delivery and catalysis performance.


I have received some noteworthy awards for my involvement in a range of outreach activities. As the University of Bristol representative, I have been selected to present my work to MPs at the prestigious STEM for BRITAIN in the Houses of Parliament. My research contributions to the University of Bristol and to the wider community have been recognised by the Inspirational Bristol Scientist Award in 2019.


Defective hierarchical porous copper-based metal-organic frameworks synthesised via facile acid etching strategy

Introducing hierarchical pore structure to microporous materials such as metal-organic frameworks (MOFs) can be beneficial for reactions where the rate of reaction is limited by low rates of diffusion or high pressure drop. This advantageous pore structure can be obtained by defect formation, mostly via post-synthetic acid etching, which has been studied extensively on water-stable MOFs. Here we show that a water-unstable HKUST-1 MOF can also be modified in a corresponding manner by using phosphoric acid as a size-selective etching agent and a mixture of dimethyl sulfoxide and methanol as a dilute solvent. 

Interestingly, we demonstrate that the etching process which is time- and acidity- dependent, can result in formation of defective HKUST-1 with extra interconnected hexagonal macropores without compromising on the bulk crystallinity. These findings suggest an intelligent scalable synthetic method for formation of hierarchical porosity in MOFs that are prone to hydrolysis, for improved molecular accessibility and diffusion for catalysis.

Controlled formation of hierarchical metal–organic frameworks using CO2-expanded solvent systems

This work concerns the rapid synthesis of an archetypical metal-organic framework (MOF) material (HKUST-1) whereby the addition of supercritical CO2. The advantages of this method are that it allows a drastic reduction in the amounts of conventional solvents required for synthesis whilst removing the need for a separate post-synthetic solvent removal step and affording control over macroporosity in the resulting crystallites.
