Giving a class in Nextflow at the University of Chile (2025)

I’m a Bioinformatics Developer, currently working towards a PhD in Bioinformatics at the Dalmolin Systems Biology Group. I’m experienced with software development in Python and R, particularly in what pertains to scientific software and data analysis.

I also develop courses in subjects that interest me - I’ve taught short courses in Docker, Git (including one at Anaconda Learning!) and Nextflow (I’m also a Nextflow Ambassador!).

My interests include, but are not limited to: Single-cell transcriptomics, network biology and scientific software.
