Echinoid systematics and evolution

When I was about 8 years old, I sat at the kitchen table and used a blue ballpoint pen to draw the "blueprints" for the research vessel I would be using when I became a marine biologist. Things don't always go the way you plan--even when you start early. But I can say that my life as a field biologist and phylogeneticist of marine organisms has never wavered from the exciting endeavor represented by those childhood sketches.

Hudson Pinheiro
Postdoctoral Fellow
Biodiversity, ecology and evolution of mesophotic reef fishes

The study of mesophotic reef fish communities is among my major research interests. I am exploring biodiversity and evolutionary processes of reef fishes in isolated seamounts and oceanic islands of the Atlantic Ocean. The discovery of endemic species and the assessment of their distribution and genetic patterns have contributed to a better understanding about the origin of species and biodiversity in these isolated environments.

Systematics, Biogeography, Taxonomy, Malagasy flora

My research interests focus on the taxonomy, systematics and biogeography of the Malagasy flora. I am conducting ongoing research on the St. John’s wort family, Hypericaceae, and the princess flower family, Melastomataceae, and am also investigating the relationships between Malagasy species and closely related groups from mainland Africa and the New World.
