Presentation

I am a postdoctoral researcher at the Division of Plant Biotechnology, specialising in the applications of new genomic techniques (NGTs) in potato and other crops. With a Ph.D. in Biological Sciences earned from the University of Buenos Aires, Argentina (2021), my doctoral research focused on the application of CRISPR/Cas9 to enhance post-harvest quality in potato tubers. 

Currently, I’m focusing on refining NGTs for higher precision and broader application, including homology-directed sequence integrations into the potato genome, aiming at an enhanced starch quality tailored to specific industrial applications. Additionally, I am exploring the application of NGTs in the industrial oil crop Camelina sativa, aiming at an enhanced accumulation of medium-size fatty acids in the seed lipids.  

Key Research Interests

Genome editing in crops (CRISPR/Cas9, CRISPR/Cas12a, RNP)

Homology-directed repair (HDR) and precision gene editing

Starch biosynthesis

Public acceptance and regulation of NGT-derived crops

Research

Starch is the principal storage carbohydrate in plants, accumulating in amyloplasts of seeds and storage organs, like tubers. Storage starch serves in human nutrition and industrial applications, and potatoes are among the most significant starch sources globally. My research focuses on developing biotechnological strategies to improve starch quality and accumulation in potato tubers, by exploring the molecular mechanisms governing its biosynthesis. I am employing NGTs like gene editing to deciphering the genetic networks involved in starch synthesis. Furthermore, I use a transgene-free approach for gene editing based on the isolation and transfection of potato protoplasts, followed by plant regeneration, which offers an effective breeding tool for obtaining varieties with novel starch qualities tailored to industrial applications. 

Teaching and supervision

I participate as lecturer in the course Plant Growth and Development from the MSc program in Plant Biology for Sustainable Production, Swedish University of Agricultural Sciences.
