Areas of expertise
Dr Medina obtained his PhD degree in Microbiology in 2007 at the University of Valencia (Spain). He was awarded the prize for the best PhD Thesis by the University of Valencia based on the novelty and quality of his research in 2008. Subsequently, he worked for almost 2 years in the food industry until he obtained a post-doctoral grant from the Spanish Ministry of Science and Innovation to work in the Applied Mycology Group at Cranfield University (UK) from January 2009 to August 2010. During this post-doctoral training period, he applied and was successfully granted a Marie Curie Individual Fellowship (Intra-European Fellowships for Career Development) to develop the project “Mechanism of action of antifungals against mycotoxigenic species: from molecular to phenotypic efficacy” (PIEF-GA-2009-253014) (September 2010 to August 2012). He was then part of the Applied Mycology group as Research Fellow until October 2013.
Dr Medina re-joined the Applied Mycology group (September 2014) in the new Cranfield Soil and AgriFood Institute as Research Fellow. He was quickly promoted to Academic Fellow and later on to Lecturer in Food Mycology (early 2016).
Dr Medina is currently leading research in relation to Climate Change impacts on fungal diseases of plants. He is focused on pre- and post-harvest approaches to enable fit for purpose accurate risk predictions, control and minimisation strategies for mycotoxin contamination and food waste under current and expected climate change conditions in key staple chains. This is complimented by work on the mechanisms used for ecophysiological tolerance to environmental stress and transcriptome (RNAseq) of mycotoxigenic moulds.
Parallel with this, Dr. Medina is responsible for managing the AgriFood suite of MSc Courses (3 courses), and is Director of the MSc in Food Chain Systems. In November 2017, he successfully completed the 1st Module of a PGCert in Academic Practice at Cranfield University and is now an Associate Fellow of the Higher Education Academy.
Dr. Angel Medina has focused his research interests on the impact that environmental stress has on the functioning of fungi (mainly mycotoxigenic species), the mechanisms used for ecophysiological tolerance, and the molecular basis of secondary metabolite production, especially mycotoxins. He has been developing research on ecophysiology, molecular ecology and modelling of mycotoxigenic fungi growth and toxin production for more than 15 years.
His current key research/interest areas are:
Other tasks include: supervision of PhD, MSc and Erasmus student projects.
