Research Topics:<\/strong> Dr. Keagan Pokpas joined the University of the Western Cape, Chemistry Department in 2018 as a Nano-Electrochemistry and Sensor technology lecturer under the SARCHI chair initiative. He completed his MSc in Nanoscience with a focus in Nanochemistry in 2014, the first of its kind on the African continent, as a part of the National Nanoscience Postgraduate Teaching and Training Program (NNPTTP). He later went on to receive his PhD in Electroanalytical Chemistry from UWC in 2017 prior to completing a postdoctoral fellowship in SensorLab with a focus on paper-based microfluidics.<\/p>\n<\/div>\n\n\n\n

Dr. Pokpas\u2019 research interest is in developing low-cost, disposable and integrated devices for early diagnostics and sensing of environmental and medical contaminants that plague the African continent. His research focus has been in the development of metal-graphene nanocomposites for stripping voltammetric applications and trace-metal analysis in environmental water samples. Due to the increased attention in paper-based diagnostics and microfluidics systems for on-site monitoring, Dr. Pokpas\u2019 research interests have expanded to include paper-based microfluidics, paper-based energy systems, conductive ink fabrication, materials printing and anti-breast cancer drug detection. His research further covers the interrogation of rheological properties of various samples. Dr. Pokpas has served as a member of the International Society of Electrochemistry (ISE) since 2012 and a member of the South African Chemical Institute (SACI) since 2013.<\/p>\n\n\n\n
