MChem, DPhil (Oxon)
Karwei completed her DPhil in Materials Science at the University of Oxford. Prior to her DPhil, she obtained her Master’s degree in Chemistry at the University of Durham. Karwei is based in our Hong Kong office and joined Brookes Bell as a Scientist in January 2019. She is fluent in speaking English and Cantonese and has a basic understanding of Japanese.
Karwei’s MChem research used a solid-state synthesis to produce photocatalysts for water purification. These materials were characterised and tested using a range of techniques, including XRD, BET, UV-Vis spectroscopy and DRS.
Karwei’s DPhil research topic was on optimising the production of carbon nanomaterials filled with magnetic metals and creating macrostructures from these nanomaterials. As part of her DPhil, she was the lead researcher in multidisciplinary collaborations with the Department of Engineering, University of Oxford, and the Bio-Nano Electronics Research Centre, Kawagoe, Japan. Throughout her DPhil, she developed strong skills in a range of analytical chemistry techniques, including SEM, TEM, EDX, SQUID, XPS, Raman spectroscopy, IR spectroscopy, XRD and contact angle measurements.
Karwei has attended onboard vessels and commodity facilities to investigate the extent and cause of cargo deterioration, cargo fires, and issues with minerals, such as liquefaction, contamination and quality matters. She has designed sampling protocols and overseen sampling of cargoes. Karwei has attended at laboratories to oversee sample analyses and interpreted the results for various commodities. She has also provided advice for the safe carriage of potentially dangerous goods.
