Biology, Chemistry and Forensic Science

Iza has an MSc in Biological Sciences from the University of Silesia, Poland completed in 1990. Within biosciences she first specialised in anatomy and histology (interactions between heavy metals and enzymatic activity in brain tissue). In 1991 she took a position as a junior research worker in the Institute of Polymer Chemistry at the Polish Academy of Sciences in Zabrze, Silesia, with a special interest in the biodegradability of different synthetic polymer blends. After one year there she decided to take a PhD researcher/lecturer post at the University of Silesia, Katowice, with a special interest in microbial biotechnology concerning the production of biodegradable polymers by bacteria under different environmental conditions. Iza completed my PhD in the Department of Biochemistry, University of Silesia, Katowice.

Iza joined the School of Applied Sciences at the University of Wolverhampton in September 2000. Since then she has continued her research into the production of biodegradable plastics from bacteria. Her research is focused on the cost-effective production of novel bio-based polymeric from waste.  Iza has published numerous research papers in highly ranked scientific journals, authored several chapters in biotechnological books. Iza has also given a broad number of invited lectures at international conferences.

She was awarded a Mercia Spinner Pathfinder concept grant and Enterprise Fellowship Scheme to develop new biopolymer extraction methods from bacteria grown in large fermenters.

Iza teaches on a wide variety of microbiology and biotechnology courses, both undegraduate and postgraduate level where she puts her knowledge and experience to good effect. Iza is also active member of the University of Wolverhampton Antimicrobial Research Development (UWARD) group.

Iza also is a tutor for Erasmus/Socrates exchange students.
