CS + Social Good
Through TechReach, a new student club, Caltech undergrads aim to use tech skills to address social problems. Among people who are homeless, lack of connection to family and friends poses an often-overlooked obstacle to stability and well-being. Nivetha Karthikeyan, Myra Cheng, and Andrew Hess address the problem by developing new technological tools for Miracle Messages, a nonprofit that helps reunite homeless people with friends and relatives. Miracle Messages helps homeless individuals record video or audio messages to loved ones they have lost all contact with, and then volunteers scour social media and other digital platforms to find those loved ones and deliver the message. They hope to expand TechReach to five or six new projects involving larger numbers of computer science volunteers and a broader range of issues.
Winners of the 2019 Demetriades - Tsafka - Kokkalis Prizes Announced
The student winners of the 2019 Demetriades - Tsafka - Kokkalis Prizes were announced at the end of this academic year. Anupama Lakshmanan, advised by Professor Mikhail Shapiro has received the prize in Biotechnology. Her research is in engineering of acoustic protein nanostructures for non-invasive molecular imaging using ultrasound. Seyedeh Mahsa Kamali, advised by Professor Andrei Faraon has received the prize in Nanotechnology. She focuses on changing paradigms in optical design through engineering materials at the nanoscale. Linqi (Daniel) Guo, advised by Professor Steven Low has received the prize in Environmentally Benign Renewable Energy Source. His research quantifies the impact of transmission network topology in electrical power system robustness against disturbances and failures. Chris Rollins, advised by Professor Jean-Phillippe Avouac has received the prize in Seismo-Engineering, Prediction, and Protection. Chris studies the way that the Earth deforms gradually over periods of years and decades and uses this to shed light on how earthquakes work, where and how often they might occur in the future, and the hazard they may pose. Nicholas Flytzanis, advised by Professor Viviana Gradinaru has receive the prize in Entrepreneurship. His research is in engineering viruses to serve as next-generation gene therapy delivery vehicles for the treatment of human disease.

Undergrad Weighs in on Privacy Laws
Computer science junior Rona Yu has embarked on a yearlong project to answer the question: “What should the nation be doing, right now, to draft a privacy regulation?" She has written a paper that covers the points that new privacy legislation should be prioritizing, as well as the potential unintended consequences of the legislation that has been proposed. She is also preparing a document describing her findings that I will submit to the Federal Trade Commission. [Caltech story]
Professor Beck Receives Masanobu Shinozuka Medal
James L. (Jim) Beck, George W. Housner Professor of Engineering and Applied Science, Emeritus, has received the American Society of Civil Engineers (ASCE) Masanobu Shinozuka Medal, "for his original contributions to subset simulation in reliability analysis of stochastic systems, a powerful technique that allows probabilistic estimation of rare events; for his pioneering work in developing technologies for machine learning in earthquake engineering applications." The medal is given in recognition of outstanding contributions to the field of stochastic mechanics, reliability and risk and simulation. [List of medal recipients]
Undergraduate Students Win International Data Science Competition
Undergraduate students Hongsen Qin, Emma Qian, Thomas Hoffmann, and Alexander Zlokapa (advised by Professors Aaron Ames, Erik Winfree, Jonathan Katz, Maria Spiropulu, and Yaser Abu-Mostafa) have won the Citadel Data Open International Data Science Competition. This winning team chose to investigate the optimal way to spend $1 billion to save lives from malaria and sanitation-related diseases, allocating funds for different prevention methods and optimizing budget breakdowns country by country. To quantify the socioeconomic impacts of their policy proposal, they modeled a variety of aspects from mosquito feeding cycles to climate change using techniques ranging from causal discovery methods to interpretable machine learning. The Caltech team was among 24 teams that were evaluated and questioned by a panel of experts including the former Chief Scientist of AI at Microsoft, a Princeton professor, and the chief of equities at Citadel. The Caltech team was chosen as the first place winner based on the depth, rigor, and comprehensiveness of their analysis.
Katie Bouman Joins EAS and CMS
Congratulations to the entire Event Horizon Telescope team, and especially to Dr. Katie Bouman who is joining the Engineering and Applied Science (EAS) Division in June as assistant professor of computing and mathematical sciences (CMS). Currently, Caltech and CO Architects are working with her to design and construct a unique laboratory that will facilitate her work in computational imaging. The laboratory is the first of its kind and is designed for her to conduct experimental work in conjunction with her computational approaches – making it possible, for instance, to observe phenomena previously difficult or impossible to measure. The black hole imaging is one spectacular example of how Professor Bouman’s algorithms are advancing our knowledge of the world; she has also developed algorithms that let us “see around corners” and detect material properties (such as stiffness and dampness) via imaging. In her work, Bouman has also developed methods to combine information from both imaging as well as acoustic systems to analyze sub-pixel scale vibrations of otherwise seemingly still objects. As a result, relatively inexpensive cameras, combined with powerful algorithms, are an increasingly attractive alternative to complex and expensive laser-based systems to sense “invisible” attributes of a material.
