Tanzeem Choudhury, associate professor of computing and information science, is developing such an application, supported by the newly created Intel Science and Technology Center (ITSC) for Pervasive Computing, a collaboration between Cornell and five other universities, managed by the University of Washington.
Intel’s goal is to develop technologies capable of continuously learning and adapting to consumers’ needs. Pervasive Computing ITSC projects include “smart houses” that monitor family activity and help out in the kitchen, as well as applications like Choudhury’s for mobile health and mental well-being. Intel is providing funding to support two graduate students for two years or more for Choudhury’s research.
“There has been some work on using phones to measure physical activity,” Choudhury said. “But sensing mental health is [somewhat] underexplored.” Previously she has used mobile sensors to map people’s social networks, a process she calls “reality mining.”
She proposes to use the phone’s microphone to monitor stress levels in speech, with privacy protection to make the actual words unintelligible. Knowing where and when stressful events occur can lead to advice on how to avoid them. The tricky part is crafting the advisory messages.
“You have to be really careful how you do the feedback, to make sure you’re not going to have an adverse effect,” she explained. “There are subtle ways of engaging a person with a problem.”
Choudhury is collaborating with Deborah Estrin, director of the Center for Embedded Networked Sensing at the University of California-Los Angeles and a leader of the Open mHealth project, which aims to use mobile devices to enhance mental health. They will draw on the advice of physicians and psychiatrists in designing their applications. She also will work with other researchers in the Pervasive Computing ITSC to extend her system’s monitoring into the smart house.
Before joining the Cornell faculty this fall Choudhury began her work on mobile health monitoring at Dartmouth, and she continues to collaborate with Dr. Ethan Berke at Dartmouth Medical School and Andrew Campbell, professor of computer science at Dartmouth.

Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Hamburg and the European Molecular Biology Laboratory (EMBL) outstation in the city have developed a new method to watch biomolecules at work. This method dramatically simplifies starting enzymatic reactions by mixing a cocktail of small amounts of liquids with protein crystals. Determination of the protein structures at different times after mixing can be assembled into a time-lapse sequence that shows the molecular foundations of biology.
The functions of biomolecules are determined by their motions and structural changes. Yet it is a formidable challenge to understand these dynamic motions.
At the International Symposium on Automotive Lighting 2019 (ISAL) in Darmstadt from September 23 to 25, 2019, the Fraunhofer Institute for Organic Electronics, Electron Beam and Plasma Technology FEP, a provider of research and development services in the field of organic electronics, will present OLED light strips of any length with additional functionalities for the first time at booth no. 37.
Almost everyone is familiar with light strips for interior design. LED strips are available by the metre in DIY stores around the corner and are just as often...
Later during this century, around 2060, a paradigm shift in global energy consumption is expected: we will spend more energy for cooling than for heating....
Researchers from the Department of Atomically Resolved Dynamics of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg, the University of Potsdam (both in Germany) and the University of Toronto (Canada) have pieced together a detailed time-lapse movie revealing all the major steps during the catalytic cycle of an enzyme. Surprisingly, the communication between the protein units is accomplished via a water-network akin to a string telephone. This communication is aligned with a ‘breathing’ motion, that is the expansion and contraction of the protein.
This time-lapse sequence of structures reveals dynamic motions as a fundamental element in the molecular foundations of biology.
Two research teams have succeeded simultaneously in measuring the long-sought Thorium nuclear transition, which enables extremely precise nuclear clocks. TU Wien (Vienna) is part of both teams.
If you want to build the most accurate clock in the world, you need something that "ticks" very fast and extremely precise. In an atomic clock, electrons are...
