Barbara Simons proves how easy it is to hack elections—and how it can be stopped

College of Engineering Distinguished Alumna Barbara Simons (Ph.D. '81) is the subject of an article in the Dail Kos titled "Computer scientist Barbara Simons proves how easy it is to hack elections—and how it can be stopped."  Simons,  who runs Verified Voting, has been a longtime advocate for bringing paper ballots back to all states and exposing the perils of electronic paperless ballots.  Last summer, she ran an experiment at the Def Con Hacker Conference in Las Vegas in which she secured 4 voting machines and had two teams of hackers successfully compromise them. “Anything that’s happening in here, you can be sure [it’s something] that those intent on undermining the integrity of our election systems have already done,” she said.  Simons will be a keynote speaker at the WiCSE 40th Reunion on Saturday.

AI training may leak secrets to canny thieves

A paper released on arXiv last week by a team of researchers including Prof. Dawn Song and Ph.D. student Nicholas Carlini (B.A. CS/Math '13), reveals just how vulnerable deep learning is to information leakage.  The researchers labelled the problem “unintended memorization” and explained it happens if miscreants can access to the model’s code and apply a variety of search algorithms. That's not an unrealistic scenario considering the code for many models are available online, and it means that text messages, location histories, emails or medical data can be leaked.  The team doesn't “really know why neural networks memorize these secrets right now, ” Carlini says.  “At least in part, it is a direct response to the fact that we train neural networks by repeatedly showing them the same training inputs over and over and asking them to remember these facts."   The best way to avoid all problems is to never feed secrets as training data. But if it’s unavoidable then developers will have to apply differentially private learning mechanisms, to bolster security, Carlini concluded.

Shankar Raman named 2018 MIT MacVicar Fellow

Alumnus Shankar Raman (EE M.S. '88), now a professor of literature at MIT, has been named a 2018 MacVicar Fellow.  The MIT MacVicar Faculty Fellows Program recognizes professors who are champions of teaching and advising, and who engage with students to advance the mission of the Institute.  After obtaining his B.S. in electrical engineering from MIT and master's from Berkeley, Raman changed fields and received a master's and Ph.D. in English literature from Stanford.  His research ranges from Renaissance and late-Medieval literature and culture to post-colonialism and literary theory.  His unconventional career path has proven particularly beneficial to his students. “One of the most unique and helpful aspects of Prof. Raman’s advising,” one former student wrote, “was his ability to leverage his own unique life trajectory, which enables him to connect with MIT students on their own technically-minded terms better than most.”

Dan Wallach to testify about election security and voting machines in Texas

EECS alumnus Dan Wallach (B.S. '93) will testify before the Texas Senate Select Committee on Election Security at a hearing about recent election irregularities in Texas, a review of voting security protocols and the responsibilities and duties of members of the Electoral College.  Specifically, the hearing will examine the use of electronic voting machines and paper ballots, voting fraud and disenfranchisement occurring inside nursing homes and assisted living facilities, outside interference and manipulation of elections, and the voting requirements of presidential electors.  Wallach is widely regarded as an expert on voting machine security.  He is currently an EECS professor at Rice University and a scholar at Rice's Baker Institute for Public Policy. 

Steve Wozniak emphasizes people over technology

CS alumnus Steve Wozniak (B.A.'86) was the inaugural speaker in the Business Thought Leader series at the University of South Florida College of Business.  He answered pre-submitted questions that asked for his best advice for college students and what he might tell his younger self.  He shared his "smiles minus frowns" happiness equation and said that how one feels is paramount to success.  While passion and vision are key, he stressed the importance of always choosing people over technology and cautioned students that ”the purpose [of your work] should never be, this is how I’m going to make a lot of money.”  Instead, if you think about how you can make the world a better place you will never regret the outcome.  He said that he was so famous when he came back to study at Berkeley, after taking time off to found Apple Computers, that he went by the pseudonym Rocky Raccoon Clark.

Small robots with smart bodies can safely bump into obstacles

Prof. Ron Fearing's team have modified a palm-size robot with a soft, roach-like exoskeleton and six legs, called the Dynamic Autonomous Sprawled Hexapod (DASH), to use the momentum of a head-on crash to tip itself upward to climb a wall.  Kaushik Jayaram (Ph.D. Robotics/Biology '14, advisor: Robert Full) discovered how cockroaches use the energy from collisions to propel themselves up and over obstacles.  “Their bodies are doing the computing, not their brains or complex sensors,” explains Jayaram. DASH can now scurry up an incline, if equipped with gecko toes – sticky pads that Full and Fearing has also investigated and adapted for robots – they may one day become as nimble as a cockroach. The work “shows that small robots can be built with simple, robust, smart bodies to safely bump into obstacles instead of using complex and expensive sensing and control systems," says Full.

Teresa Meng on winning the game in a male-dominated industry

EECS distinguished alumna Teresa Meng (M.S. '85/Ph.D. '88) is the subject of an article in the EE Times about a keynote presentation she recently gave at the  International Solid State Circuits Conference (ISSCC) on sexism in her profession.   Meng, who was the first female professor in electrical engineering at Stanford in 1988 (she retired in 2013) and also co-founded Atheros Communications (later acquired by Qualcomm), was named one of the top 10 entrepreneurs by Red Herring in 2001.    The title of her speech was “Winning the game in a male-dominated industry” and she said that she was initially very reluctant to speak because the subject was “just too painful.”  She discussed when and how gender discrimination happens, describing “unconscious” male behaviors that hurt women and discourage female engineers from pursuing higher positions in their organizations. She also discussed how women must pick their battles.  Her talk was nothing like what anyone in the audience would have expected in the semiconductor industry — especially at a highly technical conference like ISSCC, where only 2 percent of attendees are women.

Jiawang Nie wins the 2018 SIAM Activity Group on Linear Algebra Best Paper Prize

Alumnus Jiawang Nie (Ph.D. '06, co-advisors: James Demmel and Bernd Sturmfels) has won the 2018 Best Paper Prize from the Society for Industrial and Applied Mathematics (SIAM) Activity Group on Linear Algebra (SIAG/LA).  His paper, Generating Polynomials and Symmetric Tensor Decompositions, Foundations of Computational Mathematics, was deemd the most outstanding paper, as determined by the prize committee, on a topic in applicable linear algebra published in English in a peer-reviewed journal.  8 out of 11 of the previous awards, which are  chosen every 3 years, have gone to EECS faculty, postdocs, and graduate students.  Nie is now a Professor of Mathematics at the University of California, San Diego.  He will present his work in Hong Kong on May 4-8 at the SIAM Conference on Applied Linear Algebra (SIAM-ALA18).

Mostafa Kaveh named University of Minnesota CSE interim dean

EE alumnus Mostafa “Mos” Kaveh (M.S. '70) has been named interim dean of the College of Science and Engineering (CSE) at the University of Minnesota.  CSE, the University's second largest college, spans 12 departments and is ranked among the top engineering and science academic programs in the country.  Kaveh joined CSE in 1975 as an electrical and computer engineering faculty member and most recently served as associate dean for research and planning.  His research is primarily in the areas of statistical signal processing, communications, and image processing.
