Here you find information about our current lab members. After 16 years at USP I was lucky to have the opportunity to work with a special group of people. Information on former lab members is available here. Our lab also host undergraduate and visiting students, please click here.

Paulo R. Guimarães Jr. (Miúdo)
Full Professor at the Departamento de Ecologia, IB - USP Interests: how ecological networks shape and are shaped by ecological and coevolutionary processes. I explore this problem by integrating data and natural history of ecological interactions, network science, and mathematical modelling. Selected publications: Guimarães, P. R. 2020. The structure of ecological networks across levels of organization. Annual Review of Ecology, Evolution, and Systematics 51:433-460. Guimarães, P.R., M. M. Pires, P. Jordano, J. Bascompte, J. N. Thompson. 2017. Indirect effects drive coevolution in mutualistic networks. Nature 550: 511–514. Guimarães, P.R., P. Jordano, J. N. Thompson. 2011. Evolution and coevolution in mutualistic networks. Ecology Letters 14: 877-885 [PDF]. See also the article in Science highlighting this study: [Editors' Choice].

Special Guest Members

Alice
Alice joined the lab in 2012. Alice is interested in butterflies, toucans, flowers, hummingbirds, sacis, arts and science (especially Albert Einstein's ideas). She is now testing predictions of entropy-based theories, using her bedroom as studied system. |

Marina
Marina joined the lab in 2015. Marina is interested in whales, mermaids, perching birds, Dengo's chocolate, turtles, giraffes, and especially sloths (what makes me pround). She is now applying Chaos Theory to the dynamics of toy models. |
