Dr Regeane Bagonyi

Research Associate



Biography:

Regeane obtained a B.Sc. in Chemistry (UFMG, Brazil) in 2010. Her B.Sc. final project was carried out at the Quality Control Laboratory of the Ezequiel Dias Foundation and her dissertation involved the development and statistical validation of an HPLC methodology for thalidomide analysis within the pharmaceutical production line. This project was awarded the maximum grade. She continued her academic education in Brazil completing in 2012 a M.Sc. in Science and Technology of Radiation, Minerals and Materials (CDTN). During her M.Sc., Regeane proposed and statistically optimised a remediation strategy employing oxidative precipitation to tackle manganese contamination from acid mine drainage affecting a deactivated uranium mine.

Later in 2012, Regeane was awarded a scholarship within the CAPES/COT collaboration program (UK/BRAZIL) to complete her PhD in the Engineering Department at the University of Cambridge. Her work was supervised by Professor Abir Al-Tabbaa and focused on the development of low-pH magnesia-bearing cements for the immobilisation of radioactive waste. The investigations employed statistical optimisation and geochemical modelling (PHREEQC) to design mixtures, assess the long-term degradation and radionuclides retention capabilities of novel matrices exposed to groundwater. 

Currently, Regeane works as Research Associate in the Resilient Materials 4 Life (RM4L), a project that, using the biomimetic approach, aims to create sustainable and resilient materials and structures that continually monitor, regulate, adapt and repair themselves without the need of external intervention.
