Chemical Education

  • The RSC Missing Elements report provides clear evidence that racial and ethnic inequalities are pervasive in the chemical sciences community both in academia and in industry and creating an inclusive and diverse culture will lead to better science and a more cohesive and successful society. Data from the Higher Education Statistics Agency (HESA, UK) illustrates a ‘leaky pipeline’ in the qualifications obtained and career progression of minoritised ethnicities in chemistry. Minoritized ethnicities are more likely to be underemployed, under­promoted and underrepresented in senior positions in the UK, and this is more pronounced in STEM careers.
  • QMUL is in a unique position within the Russell Group to address the issues raised in the RSC Missing Elements report viz. addressing systemic racism, and racial and ethnic inequalities in the chemical sciences community. QMUL UG intake comprises 92% from state schools, 75% are minoritised ethnic, 49% 1st in family to HE and 30% have an annual taxable income <£20k.
  • Through the MEGS grant (£108k) in collaboration with colleagues with Imperial College London (ICL) and Greenwich University (GU) we have extended the Highlighting Minorities in Chemistry (HMiC) “Colouring the Curriculum - Inclusive National Curricula in Chemistry” school/college project to UG chemistry curricula at QMUL, ICL and GU to be a pilot for the implementation of inclusive curricula nationwide.
  • We are co-creating with UG and PG students resources that will be freely available to educators throughout this country and abroad. Thus far we have identified and created profiles of ~90 chemists/scientists from diverse backgrounds that are currently overlooked in the curriculum, and these are being mapped to specific modules in the UG programmes at the three institutions.
  • Tabs on QMplus module pages in chemistry labelled “Did you Know…?” contain module specific profiles of currently overlooked scientists to ensure that information about overlooked scientists are showcased to the UG and PGT student body to act as an inspiration for them to achieve higher.

Inorganic Chemistry

The modelling of small molecule activation in biological systems such as catechol oxidase, with current interests in the catalytic activation of dioxygen and the in situ generation of hydrogen peroxide.

  • Applications include low temperature bleaching, selective oxidation, wastewater treatment, corrosion control and disinfection and the generation of labelled hydrogen peroxide species (e.g. D218O2) as well as prototypes for the detection of hydrogen peroxide vapours.
  • These interests involve the synthesis and characterisation of novel manganese complexes.
