Japan's Hokkaido University (HU) and the UMass Amherst College of Information and Computer Sciences (CICS) have embarked on a new initiative, part of the Global Institution for Collaborative Research and Education (GI-CoRE), to foster collaborative research and education activities in the areas of big data and cybersecurity. The initiative builds on the longstanding relationship between the two institutions that goes back to the founding of Hokkaido University in 1876 by William Smith Clark, the third president of the Massachusetts Agricultural College (later to become UMass Amherst).

Recognizing the economic and societal impact of the digital revolution, Hokkaido University created GI-CoRE as a vehicle to derive collaborations with a network of world-leading universities. GI-CoRE is funded by the Government of Japan and directed by the President of HU; it consists of six focal areas, called Global Stations, including Big Data and Cybersecurity (GSB) which was established in April 2016.

GSB's goals are to foster interdisciplinary research collaborations in the areas of big data and cybersecurity, to collaboratively develop curriculum and educational programs in these areas, and to facilitate joint academia-industry-government initiatives. Funding will support short- and long-term visits by computer science faculty and the hiring of graduate students and postdocs at HU to support these collaborations.

"We have a valued relationship with HU and look forward to expanding our partnerships with its world-class faculty," said Bruce Croft, distinguished professor, CICS dean, and CIIR director. "UMass Amherst will bring its unique expertise and leadership in cybersecurity and data science to engage with HU on problems of common, global interest."

A delegation from UMass Amherst - Bruce Croft, Professor James Allan (chair of the faculty and CIIR co-director), and Professor Shlomo Zilberstein (associate dean for research and engagement) - visited HU in May 2016 and participated in several events to mark the opening of GSB. Prof. Zilberstein delivered an invited talk during the opening ceremony entitled "Building Robust AI Systems" and Professor Allan spoke at the "Japan-US Academic Cooperation in Big Data and Cybersecurity" roundtable.

Professors John Staudenmayer and Erin Conlon of UMass Amherst's Department of Mathematics and Statistics are also engaged in the GI-CoRE GSB partnership.

Bruce Croft and James Allan are pictured above (far right) during their visit to Hokkaido University.

On May 6, a number of the CIIR's recent graduate alumni attended the UMass Amherst campus graduation ceremony and the CICS graduation celebration luncheon. Recent CIIR Ph.D. graduates gathered for a photo with their advisors. Shown left to right: Bruce Croft, Chia-Jung Lee, David Smith, Kriste Krstovski, James Allan, and Weize Kong. Two of the CIIR's students who received their M.S. degrees, John Foley and Manmeet Singh, also joined the CICS celebration. Recent alumni Ethem Can (Ph.D.) and Jiepu Jiang (M.S.) were not at the luncheon celebration.

CIIR doctoral student, Kriste Krstovski is a member of Aegis, a four student team that was named as one of three runner-up teams in this year's Harvard President's Challenge. Harvard President Drew Faust announced the winners and runners-up during the President's Challenge Demo Day on Monday, April 25, 2016. There were nearly 150 teams competing in this year's challenge that encourages students from across Harvard to come up with creative solutions to the world's most pressing problems

As a runner-up in the challenge, the Aegis team received $10,000. Their proposal was to build a platform that would allow users to report crime incidents and observe the crime landscape in a city. Krstovski (shown third from the right), who received his Ph.D. from UMass Amherst CICS in May 2016, is currently at Harvard University completing a Harvard-Smithsonian Center for Astrophysics SAO Pre-Doctoral Fellowship.

CIIR doctoral student, Shiri Dori-Hacohen, came in first place at the final competition of the UMass Innovation Challenge, where the top entrepreneurship teams competed for up to $65k for their startups. Shiri spoke about commercializing research on Automated Controversy Detection (with advisor James Allan). The finals, conducted by the Berthiaume Center for Entrepreneurship at UMass Amherst, were held on April 7, 2016. She won $35,000 in funding for the team's startup.

According to the UMass IC website, the UMass Innovation Challenge awards prizes each academic year through competitive events that are designed to help and reward UMass students and young alumni from any of the system’s five campuses who want to pursue a novel business idea and develop it into a marketable product.

The goal is for interdisciplinary teams to conceptualize a product with regard to its scientific and technological design, identify customers, and create a business plan for the product’s commercialization. Competition judges are entrepreneurs, legal experts, and consultants who also volunteer their time to mentor with students who are interested in marketing their new ideas.
