Research Interests

Dr. Alexander Tagg is a postdoctoral researcher. He is currently working as PI for his own DFG-funded project PaintSed here at the IOW, which aims to determine how paint particles infuence marine sediment microbial communities and use machine learning to design a model to infer paint pollution levels based on microbial community. Alongside this work, Dr. Tagg will continue to contribute to wider microplastic research. .

Dr. Tagg completed his Ph.D. at Swansea University, UK. This Ph.D. was concerned with assessing the fate of microplastics derived from industrial and domestic products in the water treatment process. This included the use of next-generation sequencing to investigate microplastic-biofilm formation in wastewater. Additionally, during this Ph.D., Dr. Tagg developed a new technique for identifying and quantifying microplastics using spectroscopic imaging, utilising a focal plane array-based reflectance micro-Fourier Transform infrared spectroscopic (FPA-based reflectance microFT-IR) approach. He then moved to the IOW and worked as a postdoc within the large BMBF-funded MicroCatch_Balt project which investigated microplastic presence in and around the Warnow river system and used information generated to build a model of microplastic dymanics within such a system.
