About me
I am interested in the many forces behind species divergence in sympatry, studying how pre- and post-zygotic barriers can participate to speciation. During my PhD, I specifically showed how differences in temporal patterns alone can generate speciation, by combining multiple field experiments and theoretical models.

My projects

Morpho butterfly

Morpho patrolling timings

Field study of diel activity patterns in Morpho butterflies across South America.

Temporal niche graph

Temporal divergence and speciation

Theoretical models of allochrony as a driver of reproductive isolation in sympatry.

XY_ Karyotype

Sex-determination and speciation

How XY vs. ZW systems shape the speed at which reproductive barriers evolve.
