Woi Pei Meng is presently an academic affiliated with Universiti Malaya who focuses on applied electrochemistry studies. She earned her PhD in Electrocatalysis in 2011, focusing on the development of solid-state electrocatalysts that were modelled after the FeFe-hydrogenases enzyme, which oversees the reversible uptake and evolution of dihydrogen and whose chemistry has potential technological significance for the transmission of clean energy. Using materials like carbon-based polymers, first- and second-row transition metals, and 2D materials, she specializes in electrode surface modification through electrochemical methods such as electropolymerization and electrodeposition. Currently, most of her research focuses on the development of electrochemical sensors, such as non-enzymatic biomedical sensors to precisely detect body metabolites like glucose, sodium, sulphate, and chloride in body fluids and a self-correcting divalent cation sensor for precision agriculture by measuring plant macronutrients at the ppm level, which can be used in the agriculture industry to avoid excessive use of fertilizers. She has also fabricated electrochemical sensors for monitoring heavy metals and volatile organic compounds (VOCs), which relate to environmental pollutants. In addition, she is studying synthetic photosynthesis with the goal of creating a solid-state electrocatalyst system that is inspired by nature to produce hydrogen and turn greenhouse gases into renewable fuel, which will help solve the world's energy problem.
