BiographyPrior to completing my doctorate, I have had 14 years of industrial experience in polymer, pharmaceutical and forensic laboratories during which, I gained extensive experience in spectroscopic, chromatographic and electroanalytical methods of analysis. After completing my PhD in 2001, I took up a Postdoctoral Research position in Prof. Krzystof Matyjaszewski’s group (inventor of, atom transfer radical polymerization, ATRP) at Carnegie Mellon University (Pittsburgh, USA), from 2002 to 2004. In April 2006, I joined the Chemistry Department as a lecturer teaching Analytical Chemistry. In 2010, I started the Graphene laboratory, which is one of five laboratories within SensorLab group.
ResearchElectro-analytical techniques are characterized by their simplicity, low cost and portability. The combination of electro-analytical techniques with graphene nanocomposites creates a portal for the development of analytical procedures for determining a myriad of analytes that are of importance at the parts per billion level. My research current interest involves the development of graphene and graphene-polymer nanocomposites for electrochemical sensing platforms for determining heavy metals and organic pollutants. The evolution of this research is now progressing towards paper microfluidic devices (PuFDs) with electrochemical detection for toxic pollutants determinations.

The ubiquitous use of pharmaceuticals, both prescribed and over the counter, has resulted in continuous discharge of pharmaceuticals and their metabolites into wastewater. The World Health Organisation (WHO) has classified pharmaceuticals in drinking-water as an “emerging issue” which requires constant monitoring and re-assessment of guidelines for safe water use. The use of electrochemical sensors as sensitive and selective analytical tools has been established unequivocally for the evaluation and monitoring of analyte species in the environment; in food; in water and the health industry. Semi-conductive polymers and polymer composites may be readily synthesised as electrochemical transducers onto screen-printed electrodes in the design of highly specific and sensitive analytical devices, that are capable of multi-element analysis, are cost effective and remotely deployable for species evaluation and quantitative analysis. The primary focus of the SARChI chair in Analytical Systems and Processes for Priority and Emerging Contaminants (ASPPEC) is the integrated application of analytical tools and technology to develop early warning systems for trace-level detection and quantification of critical contaminants. These systems are primarily electrochemically driven but draw on a wide range of supporting analytical techniques and energy sources for feasible outcomes. In a revolutionary partnership with University Cergy-Pontoise (Paris, France), Baker is Co-director of the first International Associated Laboratory (IAL) established between SensorLab (UWC) and an esteemed external research, teaching and training laboratory. Baker was appointed as Fellow in Residence on the Paris-Seine Initiative for Excellence (March-June 2020) to cement this partnership, which will offer internationalisation opportunities for many researchers and students alike. The IAL will pursue the synergy of new and renewable energy sources as a complement for sensor operations in the greater scheme of the Internet of Things.

He has been a visiting scientist at several institutions in Africa, Europe and the USA.
My research work involves the study of natural products derived from medicinal plants of South Africa. The main objective of the studies is to understand which chemical structures might be implicated in the therapeutic effects associated with the use of these plants as medicine. An effort to describe a broader natural product profile of selected plants is also pursued, as this may be of interest in the context of quality control when a particular plant becomes commercialized in future. Laboratory activities involve the application of modern chromatographic and spectroscopic techniques, such as HPLC, TLC, GC-MS, LC-MS, NMR, UV and IR spectroscopy. Some of the work is conducted in collaboration with other scientists at national and international levels.
