A venue to connect researchers interested in Physics of Life within South America
We are a growing South American network of scientists united by a shared passion for advancing physics of life — where physics meets life’s complexity. Born from a collaborative workshop at ICTP-SAIFR in 2025, our community strives to span researchers, students, and institutions, working together to bridge disciplines and borders.

Abstract: Mitochondrial shape and motility emerge from the interplay between active cytoskeletal forces and thermal fluctuations in the crowded cellular environment. In our group, we investigate the mechanical principles governing mitochondrial dynamics by combining high-resolution live-cell imaging with quantitative physical modeling. Tracking individual mitochondria in Xenopus laevis melanophore cells, we analyze transport dynamics, shape fluctuations, and mechanically induced jittering. Our results identify microtubules as the dominant mechanical scaffold driving long-range transport, elongation, and force transmission, while actin filaments impose constraints on mitochondrial mobility and morphology. We introduce a minimally invasive quantitative method to detect localized active force impulses acting on mitochondria and to separate them from background thermal noise. Our findings frame mitochondrial behavior as an out-of-equilibrium mechanical process governed by cytoskeletal force transmission, highlighting the role of intracellular mechanics in organelle dynamics.

Group of researchers that participated in the School and Workshop on the Physics of Life at ICTP-SAIFR, São Paulo, Brazil, in March, 2025 — A kickoff event for the Physics of Life South American Network, POLSAN.
Hybrid Seminars
Regular talks featuring experts on topics of Physics of Life. The organization of the seminars rotate among the subnetworks.
Some hybrid seminars can be attended in person at designated hubs — join locally to watch live, whether the speaker is on-site or streaming remotely. You are always welcome to join the seminars remotely as well!
Fostering Collaborations
The network is a great way to connect with peers that have similar interests and complementary skills!
Schools & Workshops
We are always interested in organizing schools and workshops on the different topics of Physics of Life.
We encourage the submission of proposals to ICTP-SAIFR to organize schools and workshops in the different areas of physics of life. For 2027 proposals, the application deadline is Jan. 15th 2026. Read here for more information.
Mobility Grants & Funding
We strive to make available information on mobility grants and funding for researchers to collaborate across institutions.
We also encourage members to write joint grants, including the possibility of constructing partnerships with different funding agencies across borders.
