HIGHLIGHTS OF 2018

I participate in the consortium that have sequenced the genome of a cockroach (Blattella germanica) and a termite (Cryptotermes secundus), doing a comparative analysis of genomes that provides key information about the evolution of insect eusociality. We also sequenced and identified, for the first time, the piRNA from a cockroach, studying its expression through the different developmental stages of B- germanica, and we did a comparative analysis against the piRNA from holometabolan insects showing the low level of conservation of these small non-coding RNAs between species. I was nominated as member of the ECE Praesidium.
