Peter Schroeder, Shaler Arthur Hanisch Professor of Computer Science and Applied and Computational Mathematics, and colleagues have generated a computer simulation of underwater bubble rings that is so realistic it is virtually indistinguishable from a video of the real thing. "What drives me is finding these beautiful descriptions of something that looks terribly complicated but can be reduced to a few mathematical key concepts. Then the rest just follows from there. There's beauty in seeing that a very simple principle all of a sudden gives rise to the complex appearance we perceive," Professor Schröder says. [Caltech story]
Marco Bernardi, Assistant Professor of Applied Physics and Materials Science, was a recipient of the Emerging Young Investigator Award at the 4th Functional Oxide Thin Films for Advanced Energy and Information Technology Conference. Professor Bernardi also gave an invited talk entitled “Advances in Computing Charge Carrier Dynamics in Oxides From First Principles.”
MedE Professors Wei Gao and Lihong Wang are working on microrobots that can deliver drugs to specific spots inside the body while being monitored and controlled from outside the body. "These micromotors can penetrate the mucus of the digestive tract and stay there for a long time. This improves medicine delivery," Professor Gao says. "But because they're made of magnesium, they're biocompatible and biodegradable." [Caltech story]
The paper "Distributed multi-target relative pose estimation for cooperative spacecraft swarm" co-authored by GALCIT students Kai Matsuka, Sorina Lupu, Yashwanth Kumar Nakka, and Rebecca Foust, as well as Professor Soon-Jo Chung and JPL Chief Technologist, Dr. Fred Hadaegh has won one of the two Best Student Paper awards at the 2019 International Workshop on Satellite Constellations and Formation Flying (IWSCFF). The paper presents a multi-agent localization algorithm architecture applied to a large-scale spacecraft swarm. The proposed algorithm is verified by simulation and robotic experiments using the air-bearing spacecraft simulators. The team also acknowledged the work of two Caltech undergraduate students Aaron Feldman and Jennifer Sun for their contribution to the robotic experiments. [Read the paper]
Konstantin Zuev, Lecturer in Computing and Mathematical Sciences, is the recipient of the 2019 Northrop Grumman Prize for Excellence in Teaching. The Prize is awarded to an EAS professor or lecturer who demonstrates, in the broadest sense, unusual ability, creativity, and innovation in undergraduate and graduate classroom or laboratory teaching. A nomination for Konstantin Zuev read, "It is not just his major contributions in terms of teaching classes and designing new ones that set him apart and make him an ideal candidate for the Northrup Grumman teaching award. It is his rapport with the students, and the passionate love they show for his teaching and his classes."
Michael Ortiz, Frank and Ora Lee Marble Professor of Aeronautics and Mechanical Engineering, has received the highest academic distinction from the Polytechnic University of Madrid (UPM) in a ceremony chaired by its Rector, Guillermo Cisneros, accompanied by José Manuel Torralba, general director of Universities and Superior Artistic Teachings of the Community of Madrid. Professor Ortiz was recognized as one of the leaders in theoretical and computational solid mechanics. Rector Cisneros stated that the curriculum and life path of Professor Ortiz is "an example of what a true Master - teacher with capital letters - should achieve or at least maintain as a goal.

Manuel P. Soriaga, Research Professor of Applied Physics and Materials Science, passed away on July 17, 2019. As a principal investigator in Caltech's Joint Center for Artificial Photosynthesis (JCAP), Soriaga studied electrochemical reactions that make artificial photosynthesis possible. "Manny’s accomplishments as a surface scientist were peerless and of the highest quality, and he made essential and indispensable contributions to JCAP’s mission," says Professor Harry Atwater. "All who knew him well will also remember with fondness the warmth and humor that he brought to his work and life." [Caltech story]
Leonardo da Vinci studied the motion of blood in the human body. He was interested in the heart’s passive, three-cusp aortic valve, which he realized must be operated by the motion of blood. He theorized that vortices curl back to fill the cusps in the flask-shaped constriction at the aorta’s neck. Morteza Gharib, Hans W. Liepmann Professor of Aeronautics and Bioinspired Engineering; Booth-Kresa Leadership Chair, Center for Autonomous Systems and Technologies; Director, Graduate Aerospace Laboratories; Director, Center for Autonomous Systems and Technologies, has used modern imaging techniques to demonstrate the existence of the revolving vortices that Leonardo interpreted as closing the valve.

Mechanical engineering student Timothy Chen, advised by Professor Melany Hunt, is a recipient of the 2019 Henry Ford II Scholar Award. Timothy is drawn to mechatronics, primarily to robotics and autonomy. The Henry Ford II Scholar Award is funded under an endowment provided by the Ford Motor Company Fund. The award is made annually to engineering students with the best academic record at the end of the third year of undergraduate study.
A team of researchers including Noah Olsman (PhD ’19), John Doyle, Jean-Lou Chameau Professor of Control and Dynamical Systems, Electrical Engineering, and Bioengineering, and Richard Murray, Thomas E. and Doris Everhart Professor of Control and Dynamical Systems and Bioengineering, has developed a set of guidelines for designing biological circuits using tools from mechanical and electrical engineering. Like electric circuits—but made out of cells and living matter—biological circuits show promise in producing pharmaceuticals and biofuels. [Caltech story]
