Crisanti's work exploits the biological properties of a class of selfish genetic elements (homing endonuclease) to develop a gene transfer technology.

[3][4] In 2018, Crisanti and colleagues demonstrated that CRISPR/Cas9 can be programmed to attack a conserved region of the sex determination gene, doublesex, which impairs female mosquito development and could spread effectively to 100% of a population in a few generations.

[9] In March 2020 during the COVID-19 pandemic in Italy, Crisanti conducted analysis of citizens in Vò and found that most of the infected people were asymptomatic carriers; without symptoms but capable of spreading the COVID-19 virus.

Crisanti demanded and obtained the co-operation of the President of Veneto, Luca Zaia, in the teeth of opposition by the WHO, which had co-opted the administration of Giuseppe Conte.

I think what Donald Trump did [moving to pull United States out of WHO] is one of the few things he's done that I can agree with.Andrea Crisanti is married with Nicoletta and has a son, Giulio; he considers himself Roman Catholic.
