About the Goncalves lab

Genome editing based on programmable nucleases allows for deleting, adding or “rewriting” the genetic instructions in living cells in a targeted fashion. As corollary, these technologies are having a significant impact on fundamental and applied research.

We investigate new genome editing principles based on activating and guiding specific DNA repair processes after delivering into target cells gene editing tools consisting of programmable DNA-cleaving enzymes (nucleases or “nickases”) and exogenous DNA-repairing templates (donor DNA). We further study the genome editing outcomes (wanted and unwanted) resulting from using nucleases versus “nickases” and donor DNA substrates with different structures and topologies. This research seeks to achieve seamless and scarless chromosomal DNA editing for modelling or repairing genetic defects in pluripotent stem cells and tissue-specific stem/progenitor cells. Underpinning these investigations, we develop and integrate gene delivery and gene editing technologies grounded on recombinant viruses and CRISPR-Cas9 systems, e.g., adenoviral vectors and RNA-guided nucleases, respectively.
