Google announced today a plan to lease more than 600,000 square feet of space in South Lake Union, dramatically expanding their presence in Seattle. (The Kirkland WA site – across Lake Washington from Seattle – was expanded last year. Expansion space for the current Seattle engineering office in the Fremont neighborhood at the north end of Lake Union was constrained.)

In addition to home-grown companies of all sizes – from Amazon and Microsoft to startups – Seattle is home to more than 70 engineering centers of companies headquartered elsewhere.

“There’s no one way to be a woman in technology.”

That’s one of the takeaways from a terrific article published today by GeekWire that explores the experiences of eight UW CSE alumnae since they earned their degrees 20 years ago—and how the industry has progressed over the past two decades when it comes to welcoming and advancing women. Reporter Lisa Stiffler talked with the women about their trials and triumphs as they carved out careers in a male-dominated industry.

Featured UW CSE alumnae were Gail Alverson (Ph.D., ’90), Denise Draper (Ph.D., ’95), Gail Murphy (Ph.D., ’96), Bojana Ostojic (B.S., ’95), Cathy Palmer (Ph.D., ’94), Amy Raby (B.S., ’95), Radhika Thekkath (Ph.D., ’95) and Elizabeth Walkup (Ph.D., ’95).

From the article:

“Challenges for women and minorities in tech have persisted in recent years, despite widespread efforts to increase diversity and inclusion. The spotlight on the problem has intensified in recent weeks, with tech groups holding a series of events on the topic during Women’s History Month, and shareholders pressuring tech giants to close the gender gap in employee compensation.

“To better understand these issues, GeekWire interviewed eight University of Washington alumnae who earned computer science or engineering degrees in the mid-1990s. By looking back 20 years, our goal was to see the tech world through their eyes—understanding the progress they’ve made individually, and the impediments still in the way as the industry evolves and wrestles with its diversity crisis.

“As a group, they are remarkable. Of the eight women who participated in this project, seven are still in technology. Six have children. Five worked at Microsoft at some point in their careers, and three are current employees of the Redmond, Wash.-based tech giant. Two have their own tech businesses.

“All of them still love technology and believe in its power to solve problems and create world-changing products.”

The article is accompanied by profiles of each of the women that chart their individual career trajectories and offer insights into how the industry has evolved when it comes to providing greater opportunities for underrepresented groups.

Both are must-reads! Find the full article here, and the alumnae profiles here. Read more →

The New York Times published an excellent article this week about CrowdSignals, a new initiative spearheaded by UW CSE alum Evan Welbourne (Ph.D., ’10) that seeks to build the largest set of rich, longitudinal mobile and sensor data through crowdsourcing. The community data set, which will include user interactions, geo-location and sensor data from a demographically diverse pool of users, would be available to academic and corporate researchers across a variety of disciplines to advance research, teaching and product development.

From the article:

“Words and pictures, culled from across the web, have been the digital grist for remarkable gains in computing tasks like image recognition and speech translation. But another huge data resource — sensor data from smartphones — lags behind as a fuel source for major research advances.

“CrowdSignals, a new initiative to collect, label and pay for mobile sensor data, seeks to overcome that shortfall. The organization’s approach relies less on innovation in technology than on economics and creating a marketplace for sensor data….

“‘We haven’t even begun to tap the potential of smartphone data,’ said Evan Welbourne, a computer scientist who heads the CrowdSignals project.

“The promising future of mobile data, experts agree, is that it can point the way to new insights in health care, transportation, urban planning and the social sciences.”

CrowdSignals launched an IndieGogo campaign to fund its data collection efforts, exchanging access to the data and a hand in shaping future phases of the project for a modest financial contribution. The funding will be used to pay individuals who contribute their bulk data and labeling to the project.

UW CSE professor Noah Smith, an expert in natural language processing, has received a 2016 Innovation Award from the University of Washington’s Office of Research to create a large-scale visualization of people’s perspectives on current events and issues based on digital text.

By developing tools to map the “perspectives landscape” from the vast amounts of text data available online, Smith will be able to reveal differences in framing that can affect public attitudes. His research will advance the state of the art in natural language processing while enabling researchers, policy makers and citizens to gain a better understanding of the public discourse. Although Smith’s analysis will initially focus on perspectives related to the American news media, his approach could be expanded to the international news media, social networks and other domains.

Smith’s project is one of five proposals that were chosen for funding in this latest round of the UW Innovation Awards program, which was created in 2014 to support faculty engaged in potentially transformational research in areas for which other funding sources may be limited. Last year, a multi-disciplinary team that included UW CSE and EE professor Shwetak Patel, CSE professor James Fogarty, and CSE adjunct faculty members Julie Kientz and Sean Munson received a UW Innovation Award to support the development of mobile tools for improving people’s health.

Congratulations, Noah!

Smith is recruiting a postdoc to work with him on this project. Interested individuals can view the application materials here. Read more →

A full house at the Pacific Northwest PLSE meeting

The Pacific Northwest is known to be a hotbed of programming language and software engineering (PLSE) innovation. Now, the brightest local minds in PLSE research have a forum in which to share their latest work and discuss emerging topics in the field with their colleagues from throughout the region, thanks to the efforts of professors Ras Bodik and Alvin Cheung of UW CSE’s world-class PLSE group and Rishabh Singh of the RiSE (Research in Software Engineering) group at Microsoft Research. Bodik, Cheung and Singh organized the inaugural Pacific Northwest PLSE Meeting held at the UW’s Paul G. Allen Center for Computer Science & Engineering last week—assembling a program that was chock full of new and noteworthy developments in PLSE research.

The agenda included sessions on tools and synthesis, chaired by Rishabh Singh; new languages, chaired by UW CSE professor Emina Torlak; and analysis and formal methods, chaired by Ben Zorn of Microsoft Research. UW CSE professor Zach Tatlock chaired the final session of the day, which was devoted to a series of lightning talks that illustrated PLSE’s expanding impact on fields outside of core computer science.

In his presentation to conclude the program, Ben Zorn highlighted how PLSE research is becoming more relevant to people’s everyday existence. Given the proliferation of computers in our homes, in our cars and on our bodies—and the increasingly sophisticated software required for their operation—he noted that people’s lives depend upon the work of the PLSE research community.

“The software in these objects will be written in the next five years, but will have implications for the next 50 years,” Zorn said, issuing a call to action to his colleagues to focus on developing the languages, tools and processes to ensure their safety.

Other highlights of the day included technical talks by UW CSE Ph.D. student Calvin Loncaric and professors Alvin Cheung, Michael Ernst and Xi Wang; a presentation by Kartik Chandra, a high school student who has been working with Ras Bodik, on the use of symbolic execution to verify typecheckers; and a demonstration by Microsoft Research’s Rob DeLine of a new programming language for data scientists engaged in real-time data analysis.

A team of UW CSE and EE researchers captured the Best Paper Award at the 13th USENIX Sympoxium on Networked Systems Design and Implementation (NSDI ’16) for Passive Wi-Fi: Bringing Low Power to Wi-Fi Transmissions. The Passive Wi-Fi project was developed in CSE’s Networks & Mobile Systems Lab by EE graduate students Bryce Kellogg and Vamsi Talla, CSE professor Shyam Gollakota, and CSE and EE professor Josh Smith.

Passive Wi-Fi is capable of generating Wi-Fi transmissions using 10,000 times less power than conventional methods. MIT Technology Review recently named Passive Wi-Fi among its 10 Breakthrough Technologies of 2016.

This is the second year in a row that UW CSE has taken home the big prize from NSDI, and our sixth NSDI Best Paper Award since 2007. UW ranks #1 among academic research institutions (and second only to Microsoft Research among all computing research organizations) in Best Paper Awards at major conferences in the field.

A new technology developed by UW CSE and EE researchers could take the “touch” out of touchscreen and transform the way we interact with our mobile devices. FingerIO, which was developed in the Networks & Mobile Systems Lab led by CSE professor Shyam Gollakota, employs sonar to enable users to interact with their smartphones and smartwatches by gesturing or writing on any nearby surface.

From the UW news release:

“As mobile and wearable devices such as smartwatches grow smaller, it gets tougher for people to interact with screens the size of a matchbook.

“That could change with a new sonar technology developed by University of Washington computer scientists and electrical engineers that allows you to interact with mobile devices by writing or gesturing on any nearby surface—a tabletop, a sheet of paper, or even in mid-air….

“‘You can’t type very easily onto a smartwatch display, so we wanted to transform a desk or any area around a device into an input surface,’ said lead author Rajalakshmi Nandakumar, a UW doctoral student in Computer Science & Engineering. ‘I don’t need to instrument my fingers with any other sensors—I just use my finger to write something on a desk or any other surface and the device can track it with high resolution.'”

FingerIO uses the device’s own speaker, emitting an inaudible sound wave that bounces off the user’s finger and is then recorded using the device’s microphone. That signal is used to calculate the finger’s location in space. The researchers employed a common technique in wireless communication, Orthogonal Frequency Division Multiplexing, to achieve sub-centimeter tracking accuracy.

Sonar has significant advantages over other approaches. For example, unlike camera-based finger tracking, it does not require a direct line of sight—which means it can work through fabric, such as a pocket or a sleeve. And compared to radar, sonar does not require as much computing power or custom hardware to work.

“‘Acoustic signals are great—because sound waves travel much slower than the radio waves used in radar, you don’t need as much processing bandwidth so everything is simpler,’ said Gollakota…’And from a cost perspective, almost every device has a speaker and microphones so you can achieve this without any special hardware.'”

The team, which also includes EE Ph.D. student Vikram Iyer and CSE affiliate faculty member Desney Tan (Principal Researcher at Microsoft Research), will present its research paper on FingerIO at the upcoming CHI 2016 conference in San Jose, California, where it has been recognized with an honorable mention. Nandakumar previously was awarded Best Presentation for FingerIO at the Microsoft Research Student Summit on Mobility, Systems, and Networking.

UW CSE senior Josue Rios was one of the first students to benefit from Washington State’s REAL Hope Act, an initiative that enables undocumented immigrants to access state financial aid for higher education. Nearly 20 years ago, Rios and his family left Venezuela in fear; these days, he is looking forward to graduating from UW CSE with a bachelor’s degree in computer engineering. An excellent article by UW journalism student Kayla Roberts that was published today in Seattle’s civic-focused online journal, Crosscut, highlights Rios’ journey and how the REAL Hope Act has lived up to its name:

“Josue Rios, a 21-year-old student at the University of Washington, escaped violence in Venezuela with his parents when he was two years old.

“The plan was to stay in Washington six months on a tourist visa. When his family home in Venezuela was invaded and sold on false documentation, this turned into 19 years.

“‘Because we had nothing to go back to, because everything was taken away from us, we decided to start over here,’ Rios said. This meant applying himself academically in high school and eventually pursuing a college education. He is set to graduate in the spring from the computer science and engineering department at UW.”

The author notes that because undocumented immigrants are ineligible for federal financial aid, the state program is the only government support available to enable students like Rios to pursue higher education. Read the full article here.

Rios has been an active contributor to the UW CSE community, serving as a teaching assistant in our Systems Programming and Introduction to Digital Design courses. He spent last summer as an intern at Amazon and has plans to work with Microsoft and a start-up company after graduation.

Thanks, Josue, for sharing your inspirational story. We look forward to celebrating your achievements with you in June! Read more →
