We know our science, technology, engineering, and math (STEM) workforce is crucial to America’s innovative capacity and global competitiveness. Yet women are vastly underrepresented in these fields. The 2009 US Census reveals that although women fill close to half of all jobs in the country’s economy, they hold less than 25 percent of the STEM jobs. This has been the case throughout the past decade, even as college-educated women have increased their share of the overall workforce. We simply must do more to expose young women to the opportunities in STEM fields.
Munmun De Choudhury, a postdoctoral researcher at Microsoft Research, spoke at the TEDxWomenSouthLakeUnion event in Seattle on December 1, 2012.
It was with this goal in mind that Microsoft Research Connections, Women in Bio Seattle Metro, and University of Washington’s Women in Informatics joined forces to support the December 1 TEDxWomenSouthLakeUnion event in Seattle. This was one of more than 100 local TEDxWomen gatherings held around the world on November 30 and December 1, all of them tied into the TEDxWomen 2012 event in Washington, DC, and together comprising an international call for the full participation of women and their ideas, their experiences, their compassion and convictions, their activism, and their artistry.
I was honored to serve as one of the co-hosts of this year’s Seattle event. While we streamed live talks from the TEDxWomen event in Washington, DC, we also pursued our local goal of attracting more women to STEM fields. To this end, we brought together top women in science, engineering, research, and technology from across the Puget Sound region. These STEM leaders influenced and networked with freshman and sophomore women from the University of Washington, encouraging them to pursue majors in STEM disciplines.
This year’s TEDxWomen theme was the Space Between, an exploration of what it means to live in a time of extremes, where the dialog is very much black and white even though we know our world is gray. Today’s conversations are typically framed in terms of binary extremes: men versus women, rich versus poor, liberal versus conservative, peace versus war, the haves versus the have-nots. But we know better: the world is a web of spectrums, not a linear standoff of polarities.
Our event dived into “the space between,” featuring two stellar local speakers whose talks focused on the space between our intellectual and emotional intelligence and the impact of digital technologies in this interstitial realm. Katie Davis, an assistant professor at the University of Washington Information School, discussed how digital media technologies like Facebook, Twitter, and smartphones have altered the contexts in which young people grow up. She focused on three key areas: young people's identity (experiences of themselves), intimacy (their relationships), and imagination (their world of ideas and creative expression). As Katie explained, these “three i’s” underlie what it means to be human, and they ultimately shape—and are shaped by—the society in which we live.
Our second speaker, Munmun De Choudhury, a postdoctoral researcher at Microsoft Research, discussed how emotions fundamentally direct our attention and responses to our environment, framing our attitudes and influencing our social relationships. As online social networking tools continue to gain traction among individuals, they provide a unique platform to understand human expression—whether thoughts, emotions, or opinions. Munmun described how an understanding of the rich landscape of emotions will help us better interpret the behavior of millions, while at the same time making individuals more “emotionally intelligent” by enabling them to reflect on their emotional experiences.
We also featured a bonus session: a screening of Jennifer Siebel Newsom’s Sundance documentary, Miss Representation, a powerful exploration of how the media’s many misrepresentations of women contribute to the under-representation of women in positions of power and influence. The film features interviews with leading politicians, journalists, entertainers, activists, and academics, including Condoleezza Rice, Nancy Pelosi, Rachel Maddow, and Gloria Steinem.
It was exciting to be part of a global event with a local spin, especially since the day was full of inspiration and activism. You could feel the energy of women ready to go out and make changes in the Puget Sound region and throughout the world. It was exhilarating to hear students, who had yet to declare their majors, express their desire to pursue majors in computer science and information science after the talks from Katie and Munmun.
The three co-hosting organizations have agreed to sponsor the event again next year. We look forward to an even bigger and better conference that lasts multiple days! Keep in touch and visit the TEDxSouthLakeUnionWomen webpage next autumn to learn how you can join the event.

Plant biologists in Brazil are working to develop a better understanding of tropical ecosystems—how they work and how they impact climate change, not only in the region, but worldwide. These researchers are dedicated and disciplined. They’re in the field from dawn to dusk, working through rain, wind, heat, and cold, applying all of their energy to understanding these complex ecosystems. This is intense observational work: they take copious notes and then, after grueling hours in the field, they return to their labs and flesh out their field notes in detail, striving to fully capture and make sense of what they observed. It all adds up to a long day that can take a toll on even the most committed researchers.
At the University of Campinas (better known as UNICAMP), computer science professors Ricardo Torres and Cecilia Baranauskas are exploring solutions that might help these overworked field researchers. The professors’ computer science students are creating environmental data-management apps that allow plant biologists to go to the field, observe the ecosystem, take notes by using digital devices, and then push that data to the cloud. (This work is an outgrowth of a project in e-phenology, which is supported by the Microsoft Research–FAPESP Institute for IT Research.)
Environmental data-management app for recording and sharing field observations
The environmental data-management apps should increase the precision and accuracy of the recorded data, eliminating the errors that often creep in during the transcription of handwritten notes. The ready availability of previously entered data will enable researchers in the field to easily compare new observations to past ones and to enter new information by updating a few spreadsheet cells. Moreover, by pushing the data to the cloud, it will be available to colleagues no matter where they are, enabling real-time collaboration between the researcher in the field and the team back in the lab.
With the goal of generating a variety of application ideas, the professors have split their computer science classes into multiple groups, each of which proposes a solution. Then they iterate. They talk with the plant biologists and accompany them to the field, in order to understand their needs. If all goes as planned, these students will devise applications that enable biologists to more fully record their observations in real time and preserve the record quickly, safely, and accessibly in the cloud. And what a nice convergence of high-tech computer science and shoe-leather biology that will be!

Location sensing has become ubiquitous—it’s present every time you turn on your smartphone or engage your car’s navigation system. It’s also become critical to a variety of outdoors and remote research applications, such as wildlife tracking, participatory environmental sensing, and personal health and wellness monitoring.
The Global Positioning System (GPS) is commonly used for tagging the location of data samples. But traditional GPS location fixing is a power hog; in fact, the typical smartphone battery will drain in about six hours if the phone’s GPS is constantly running, which is particularly problematic in remote locations. Moreover, a smartphone is fairly bulky—not exactly the kind of sensor you can, for example, attach to fruit bats to monitor their nocturnal flights.
Cloud-offloaded GPS may provide researchers with an energy-efficient solution for location sensing.
In a paper titled, “Energy Efficient GPS Sensing with Cloud Offloading” (PDF file, 6.13 MB), we propose a potential solution to this battery power and size dilemma. This paper describes cloud-offloaded GPS (CO-GPS), an innovative way to perform location sensing by using tiny embedded devices and the cloud to share the work of GPS signal acquisition and processing. By logging only a few milliseconds of raw GPS signals, the device can store enough information for resolving GPS-based location, and it consumes two to three orders of magnitude less energy than stand-alone or mobile phone GPS sensors. The signals are then sent to the cloud with sensor data to reconstruct the location and time that the samples are taken. In delay-tolerant, data acquisition applications—such as animal tracking, float sensor networks, participatory environmental sensing, and long-range time synchronization—CO-GPS is ideal for extending the battery life of mobile devices.
The paper received the Best Paper Award at ACM SenSys 2012—the premier conference on networked embedded sensing systems and a top forum for the sensor network research community. Many attendees consider the work to be a breakthrough in pushing continuous location sensing to extremely low power devices that can be carried by humans, animals, or recreational equipment.
We anticipate that CO-GPS will be a boon to citizen-science efforts, particularly those that rely on participatory sensing from embedded devices. For example, the CO-GPS approach is a key enabling technology in Microsoft Research Project CLEO, a participatory environmental sensing system that we are showcasing at the 2012 AGU Fall Meeting this week.
