Profs. Jiang and Zussman – Connected and Secure Humanity

Columbia Engineering recently celebrated its 150th anniversary with a look back at our proud history of discovery and achievement. From its origins as a school devoted to metallurgy and mining, Columbia Engineering contributed to the growth of a rapidly industrializing nation, and its graduates and faculty went on to transform entire industries with developments including steamboat technology, early mechanical tabulators, medical X-ray technology, and FM radio, and to lead such groundbreaking projects as New York's first subway and the world's first nuclear submarine. Today, Columbia Engineering is continuing that tradition of pushing the frontiers of engineering to address key needs of humanity and setting a bold path forward for the future. As technology moves at a rapid pace and transforms every area of  human endeavor, engineering embraces the unprecedented opportunity to bring creative solutions to the challenges of our time.

From sustainable urban infrastructure, such as green rooftops that filter out pollutants and reduce runoff, to intelligent sensor systems that monitor an individual’s energy footprint and provide actionable feedback, we are giving cities and industries the tools to keep the environment healthy. We are pioneering medical imaging techniques, developing methods for connecting people at faster speeds with less energy, creating models for preventing crises and mitigating disasters, and designing technologies to enable creative and artistic expression never seen before.

This spring, we unveil our vision for Columbia Engineering; a vision which reflects our aspirations to bring about innovative research that has a positive impact on humanity—a sustainable, healthy, secure, connected, and creative humanity. Our vision, Columbia Engineering for Humanity, is true to our history as a School and is exemplified today by the diverse and pioneering work that our faculty and students are pursuing across departments and disciplines and in partnership with sister schools, institutes, government, and industry.

We have never been more optimistic about the role engineering can play in the service of society and in bringing those advances to populations across the country and around the world.

Below are contributions of the groups of  Professors Jiang and Zussman that were described in the Spring 2017 Columbia Engineering  Magazine featured story on Columbia Engineering for Humanity.

Secure Humanity

Imagine a world where power grids are reliable, secure, efficient, and environmentally friendly.

There is no shortage of natural and human-induced factors that threaten the safety and security of humanity: external and internal attacks, extreme weather, financial catastrophes, failing infrastructure, and, increasingly, risks posed by our digital, online world.

Columbia engineers have a rich history of detecting a wide range of security threats and reducing their risks. During World War I, Professor Michael Pupin helped develop sonar technology to increase security for ships. Professor Masanobu Shinozuka PhD'60 of Civil Engineering later became a leading authority on the safety and reliability of structures, particularly their response to earthquakes.

Today, power grids-the pulse of our economies and communities-in particular are under growing stress and subject to catastrophic failure, including disruptions caused by hostile actions. Professor Daniel Bienstock of Industrial Engineering and Operations Research collaborates with Gil Zussman of Electrical Engineering to forge data-driven techniques, mathematical analyses, and algorithmic tools to uncover vulnerabilities in power grids that could be exploited by malicious actors. The same methodologies can be used to diagnose weaknesses that could become dangerous in case of severe natural events, such as major storms, or human errors. Their work aims to prevent the shutdown of power grids and resulting upheaval by designing and making networks that are not only more secure but also more resilient and able to recover faster in the event of a power outage.

Connected Humanity

Imagine a world where cities are cleaner, healthier, more secure, and more enjoyable.

An estimated 70 percent of the world's population will live in cities by 2050, creating unprecedented demand for clean air, water, energy, food, transportation, and housing. Connectivity is increasingly critical for meeting those needs and analyzing and managing services.

From its very beginning, Columbia Engineering has focused on developing technology and improving systems to help create a more connected world. In 1896, Herman Hollerith, an 1879 graduate, founded a business called the Tabulating Machine Company, which would merge with three other companies to one day become International Business Machines (IBM) Corporation. His business venture was based on a punch card system he had developed to count and sort data mechanically, an invention inspired by his work as a statistician on the 1880 U.S. Census and his belief that there could be a faster way to process data.

Today, data science is increasingly used to understand and explain connections between numbers and people. Assistant Professor Xiaofan (Fred) Jiang of Electrical Engineering and Computer Engineering specializes in the Internet of Things and has been designing sensors to monitor the urban environment-including buildings and infrastructure-to collect and analyze data. In Beijing, he developed a system of low-cost sensors that provided the first independent, real-time assessment of particulate pollution in the city. Along with his Columbia Engineering colleagues Patricia Culligan, the Robert A. W. and Christine S. Carleton Professor of Civil Engineering and associate director of the Data Science Institute, and Andrew Smyth, from Civil Engineering and Engineering Mechanics, Jiang is helping to create smarter, greener cities that will thrive for years to come.
