Brice Letcher

Researcher in Evolutionary Biology

Summary

Welcome! I am currently a post-doctoral researcher at the Laboratory of Biology and Modelling of the Cell (LBMC) in Lyon, France.

Mini-bio

After training in biology (Bsc) and bioinformatics (Msc), I did a PhD in bioinformatics in the UK, developing novel approaches to genotype microbial pathogens, with a focus on antibiotic resistance genes in M. tuberculosis and cell-surface antigens in P. falciparum.

I then moved back to Lyon for a postdoc where I have been working on the evolution of sex chromosomes and ties with the emergence of a strange mode of reproduction in nematodes, and the evolution of Programmed DNA Elimination during early embryogenesis, also in nematodes.

Research interests

Evolution of cellular processes; Evolution of reproductive systems; Evolution of host-pathogen interactions
