Dr Kimal Wasalathilake
This person does not currently hold a position at QUT.
BiographyDr. Kimal Wasalathilake is a Chemical Engineer. He received his Bachelor’s honours degree in Chemical & Process Engineering with a Minor in Environmental and Energy Engineering from University of Moratuwa, Sri Lanka in 2014. As a Chemical Engineer, he has provided consulting services to improve process efficiency in various industries such as solar salt, tea, superabsorbent, and FMCG manufacturing. These work included process design and process optimization where he performed design calculations, plant and equipment design, and system validation using simulation software.
He received his PhD from Queensland University of Technology, Australia in 2019. Under the supervision of Prof. Cheng Yan, Kimal investigated the role of modified graphene materials in energy storage devices, i.e. lithium-ion batteries, lithium-sulfur batteries and sodium-ion batteries, and utilised first-principles density functional theory (DFT) calculations to assist in the interpretation of results. He is currently working as a postdoctoral research associate in Prof. Yan’s group.
He has over five years of experience in producing and functionalizing graphene and graphene-based materials to address topics in energy storage/conversion and composite applications. This includes both experimental methods and theoretical simulations to develop novel electrode materials, composites, and electrolytes tailored to specific applications such as next generation rechargeable batteries, hybrid solar cells and fuel cells. His experimental work focuses on producing high-performance nanomaterials, electrochemistry, battery manufacturing and in-situ and ex-situ instrumental analysis. He is specialized in characterizing and analysing nanomaterials using various techniques in the areas of microscopy, spectroscopy, and macroscopic techniques, physical and mechanical property testing and high temperature processing instruments. Furthermore, he performs DFT simulations to understand the interfacial properties of the electrodes.
