Dr Mohamed Abdallah has a wide experience in applying various mass spectrometric techniques for analysis of trace levels of environmental contaminants in biotic and abiotic matrices including different human tissues. He has also made contributions to the field of human exposure to persistent organic pollutants using various exposure and pharmacokinetic models.

Dr Mohamed Abdallah is part of the Birmingham Plastics Network, an interdisciplinary team of more than 40 academics working together to shape the fate and sustainable future of plastics.  This unique team brings together chemists, environmental scientists, philosophers, linguists, economists, and experts in many other fields, to holistically address the global plastics problem.

Qualifications

Biography

Dr Mohamed Abdallah finished his bachelor studies in pharmaceutical sciences in Egypt. He then completed a taught/research masters in analytical chemistry studying the proper methods for analysis of fluoroquinolone anti-biotics in different human tissues. During his masters studies, Dr Abdallah gained theoretical and practical experience in advanced chromatographic and spectroscopic techniques in addition to applying mathematical pharmacokinetic models to predict the in vivo levels of drug doses administered via different routes in hypertensive patients. His research during the master studies resulted in 2 peer-reviwed publications in international scientific journals.

Dr Abdallah, was awarded his Ph.D from the University of Birmingham in February 2010. During his Ph.D studies, he published 19 papers in high-impact peer-reviewed journals (including 5 as corresponding author). He also participated in several international conferences with 8 oral presentations, 4 poster presentations and 26 contributions as a co-author and won two prizes for his distinguished research.

Subsequently, He took a job as a lecturer in Assiut University, Egypt, where he continued his research in the environmental health fields, published in high-impact peer-reviewed Journals (6 publications in the past 2 years) and continued his collaboration with various international research groups via a Marie-Curie Staff Exchange Scheme, before coming back to the University of Birmingham as a Marie-Curie Research Fellow.
