Background
I grew up in Rio de Janeiro, Brazil, where I got my BA in Ecology and MS in
Genetics, working with Dr. Rui Cerqueira on the life-history strategies of
small mammals. In 2001, I moved to Campinas (São Paulo) and to the Drosophila
world. During my PhD, I worked with Dr. Louis Bernard Klaczko on the recent
invasion of Zaprionus indianus in Brazil. In 2002, I had the chance to do part
of my research in collaboration with Dr. Jean David at the CNRS
(Gif-sur-Yvette, France), where I stayed for six months. Still not enough
moving, I came to Hartl lab in 2003 and worked as a technician in Yun Tao's
project of describing the molecular basis of hybrid incompatibilities. Soon
moving back to Campinas, I defended my thesis for the Universidade Estadual de
Campinas in April of 2005.
Research interests
I am interested in several aspects leading to hybrid incompatibilities in
Drosophila. In my current research I am using species of the simulans
complex to map factors that might be associated with reproductive isolation and speciation.

Hobbies
I love to study music, both theory and practice, where mandolin has been my
preferred instrument. Also, I like to attend concerts, go for walks in the sun
and camping on mountain sites.
