How Friction Evolves During an Earthquake
Professor Ares Rosakis, and colleagues including Professor Nadia Lapusta and Research Scientist Vito Rubino, are studying the way friction changes along a fault during a seismic event by simulating quakes in a lab. "Our unique facility … allows us for the first time to study friction point-wise and without having to assume that sliding occurs uniformly, as is done in classical friction studies," Rosakis explains. Professor Lapusta adds, “some numerical models of earthquake rupture … have used friction laws with slip-velocity dependence… It is gratifying to see those formulations validated by the spontaneous mini-earthquake ruptures in our study.

Professor Rosakis Named ICF Honorary Fellow and Vice President
Ares J. Rosakis, Theodore von Karman Professor of Aeronautics and Mechanical Engineering, has been named an honorary fellow of the International Congress on Fracture (ICF) which is the premier international body for promotion of worldwide cooperation among scientists and engineers concerned with the mechanics and mechanisms of fracture, fatigue, and strength of solids. He has also been elected as one of the group's three vice presidents.
123rd Commencement Ceremony
Caltech’s 123rd commencement ceremony was held on Friday June 16, 2017. The commencement speaker was Mae Jemison, an engineer, physician, and NASA astronaut. Looking up, she said, allows us to remember that there is more that connects us than divides us. "Connection to the greater universe is something I hope for you throughout your lives. Never forget to look up and keep the bigger picture in mind. Look up at the sky, the moon, the stars when you need to recharge. Let the gravity of Earth give you a warm hug when you're feeling low. Look up to remember what inspires you. Keep the sparkle in your eyes, keep it long past graduation." [Caltech story]
Professor McKeon Receives GSC Mentoring Award
The Caltech Graduate Student Council (GSC) has selected Professor Beverley McKeon as the recipient of the 2016-2017, GSC Mentoring Award. The GSC Teaching and Mentoring Awards recognize individuals “who have an extraordinary impact on Caltech graduate students through their roles as teachers and mentors.” Nominations submitted by graduate students, both within and outside of GALCIT, described her commitment as a mentor. The nominations highlighted her attentiveness, inclusivity, and great support for students.
Professor Dickinson Joins GALCIT Faculty
Professor Michael Dickinson joins the GALCIT faculty as the Esther M. and Abe M. Zarem Professor of Bioengineering and Aeronautics. Professor Dickinson has spent the last 25 years creatively pairing physics with biology to probe and understand at a detailed level how animals move, behave and make decisions – work that has advanced a number of divergent fields, ranging from aerodynamics to neuroscience. GALCIT Director Mory Gharib welcomes the potential that Michael brings to GALCIT for collaborating on activities such as development of advanced experimental techniques for unsteady aerodynamic visualizations and measurements; unsteady flight dynamics and characterization of engineering principles underlying biological systems. GALCIT is also looking forward to Professor Dickinson’s involvement in research projects under development in the Center for Autonomous Systems and Technologies (CAST) which is currently under construction in GALCIT.
