Without GPS, autonomous systems get lost easily. Now a new algorithm developed at Caltech allows autonomous systems to recognize where they are simply by looking at the terrain around them—and for the first time, the technology works regardless of seasonal changes to that terrain. The general process, known as visual terrain-relative navigation (VTRN), was first developed in the 1960s. By comparing nearby terrain to high-resolution satellite images, autonomous systems can locate themselves. The problem is that, in order for it to work, the current generation of VTRN requires that the terrain it is looking at closely matches the images in its database. To overcome this challenge, Anthony Fragoso, Lecturer in Aerospace; Staff Scientist, Connor Lee, Graduate student in Aerospace, Austin McCoy, Undergraduate, and Soon-Jo Chung, Bren Professor of Aerospace and Control and Dynamical Systems and research scientist at JPL, turned to deep learning and artificial intelligence (AI) to remove seasonal content that hinders current VTRN systems.

The student winners of the 2021 New Horizons Award were announced at the end of this academic year. Sara Beery was recognized for her passion, energy, and fearlessness to improve the CMS program by founding the Women in CMS group, organizing events and discussions on racism in academia, and advocating for the support structures that improve the educational experience for all CMS students. Abigail (Abby) Jiang was recognized for her commitment to enhance the campus environment through her leadership of the Caltech Asian Pacific Islander Desi American student association (APIDA+) and of PRISM, the Caltech LGBTQ+ association, and her advocacy for other campus diversity initiatives. Daniel Mukasa was recognized for his dedication and leadership of Black Scientists and Engineers of Caltech, which catalyzed campus engagement, reflection, and reform, and for his mentorship of undergraduates through the WAVE program. Alexander Choi, Leah Ginsburg, Marcus Lee and Victoria Lee, were recognized for their collective engagement and sustained dedication to improve the quality of life for MCE graduate students that culminated in the initiation of a seminar series, an option-wide climate survey, the appointment of a Diversity Liaison, the creation of a MCE community statement, and formation of www.deiinitiatives.caltech.edu, a campus-wide data base for DEI activities.

A good way to find out what a cell is doing—whether it is growing out of control as in cancers, or is under the control of an invading virus, or is simply going about the routine business of a healthy cell—is to look at its gene expression. Lior Pachter, Bren Professor of Computational Biology and Computing and Mathematical Sciences, has developed a complex software tool that enables the processing of large sets of genomic data in about 30 minutes, using the computing power of an average laptop. Like a Swiss Army knife, the tool can be used in myriad ways for different biological needs, and will help ensure the reproducibility of scientific studies. "The interdisciplinarity of our team was crucial to conceiving of and executing this project," says Pachter. "There are people in the lab who are computer scientists, biologists, engineers. Sina Booeshaghi is in the mechanical engineering department and brings the perspective of his design background and engineering." [Caltech story]

Aaron Ames, Bren Professor of Mechanical and Civil Engineering and Control and Dynamical Systems, has been elevated as a fellow of the Institute of Electrical and Electronics Engineers (IEEE) for contributions to hybrid and safety-critical nonlinear control with demonstration on robotic systems. The IEEE Fellow is one of the most prestigious honors of the IEEE, and is bestowed upon a very limited number of Senior Members who have contributed importantly to the advancement or application of engineering, science and technology.  [Elevated class of 2021]

Methods that were originally created to help robots to walk and autonomous cars to drive safely can also help epidemiologists predict the spread of the COVID-19 pandemic. Aaron Ames, Bren Professor of Mechanical and Civil Engineering and Control and Dynamical Systems, and colleagues took these tools and applied them to the development of an epidemiological methodology that accounts for human interventions (like mask mandates and stay-at-home orders). By utilizing the U.S. COVID-19 data from March through May, they were able to predict the infection wave during the summer to high accuracy. "This is the greatest health challenge to face our society in a generation at least. We all need to pitch in and help in any way we can," Ames says. [Caltech story]

Applied and computational mathematics student Ishani A. Karmarkar is a recipient of the 2020 Henry Ford II Scholar Award. Ishani is interested in data science and numerical algorithms, as well as applications to physical problems. This summer, she will be working on a SURF project on graph-based semi-supervised learning algorithms with Bamdad Hosseini, Senior Postdoctoral Scholar Research Associate, and Andrew Stuart, Bren Professor of Computing and Mathematical Sciences. In the past, she has also worked on a fluid modelling project with Sandra Troian, Professor of Applied Physics, Aeronautics, and Mechanical Engineering, and completed a summer internship at Facebook. 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.

Myra Cheng, an undergraduate student in computing and mathematical sciences, has been selected to receive a Goldwater Scholarship. The Barry Goldwater Scholarship and Excellence in Education Program awards scholarships to college sophomores or juniors who intend to pursue research careers in science, mathematics, and engineering. Myra works with Yisong Yue, Professor of Computing and Mathematical Sciences, and Joel Burdick, Richard L. and Dorothy M. Hayman Professor of Mechanical Engineering and Bioengineering; Jet Propulsion Laboratory Research Scientist, on optimization algorithms that can learn individual preferences based on real-time interaction with people. These algorithms can be used in wearable exoskeletons that help mobility-impaired individuals walk. "I'm interested in how machine learning interacts with humans and, more broadly, human society," she says. Cheng has also been working with Katie Bouman, Assistant Professor of Computing and Mathematical Sciences, Electrical Engineering and Astronomy; Rosenberg Scholar, and Claire Ralph, Lecturer in Computing and Mathematical Sciences; Director, Career Development Center, on developing algorithms that address questions of explainability and algorithms that affect social change.
