Current research topics/interests:

• Genetic and genomic basis of heavy metal tolerance and associated metal hyperaccumulation in plants.
• Transposable Elements dynamics in response to challenging and extreme environmental conditions.
• Transposable Elements regulation and evolution in plants.
• Comparative Genomics and Transcriptomics in Arabidopsis halleri ecotypes and related species.

Further Interests

I have a keen interest in muscular physiological, exercise and nutrition science. As a dedicated scientist, I like to stay informed in this field following research articles, news and podcasts. At times, I used my knowledge to consult people in exercise and nutrition to build and remain a strong and healthy body.
