Soodeh has a Bachelor degree in “Plant Protection” and a master degree in “Plant Biotechnology”. Since moving to Australia in 2013, she has worked as a Graduate Research Assistant at the School of Biological science and ARC center of excellence in plant energy biology for three years. During that time, she worked on gene expression analysis in canola and genotyping Arabidopsis mutants. She has also been working as a Laboratory Demonstrator in UWA since 2016. She joined Batley’s Lab and started her PhD with Prof. Jaqueline Batley from mid-2016.

Association of DNA methylation changes with resistance against Leptosphaeria maculans in Brassica napus
Epigenetic changes, including but not limited to DNA methylation and demethylation, are one of the important mechanisms involved in transcriptional reprogramming of defence genes under stress conditions. DNA methylation refers to the addition of a methyl group to the cytosine bases of DNA to form 5-methylcytosine. DNA methylation is an important and common epigenetic modification of DNA in eukaryotes and by modifying the gene expression pattern during growth stages and stress conditions can play an important role in protecting plants from stress conditions. Crops of the genus Brassica are frequently named as plants with high nutrition values which are used throughout the world. Blackleg, caused by Leptosphaeria maculans, is one of the major diseases of Brassica species and can cause a significant yield loss annually. Based on the importance of DNA methylation changes in plants under stress conditions, the aim of Soodeh's project is to investigate the genome-wide DNA methylation in Brassica napus cultivars and its role in resistance against L. maculans.
