October 2018: Behnaz Arzani, one of my former Ph.D. students co-advised with Boon Thau Loo and currently a post-doctoral researcher at Microsoft Research was named one of 10 N2Women: Rising Stars in Computer Networking and Communications. Congratulations to Behnaz and well-deserved.
August 2018: The 2018 ACM SIGCOMM conference was successfully held in Budapest, Hungary. Thanks to Sergey Gorinsky and János Tapolcai for a great organization. If you go to the conference Program page, you will find links to the papers and their slides as well as streamed videos from all the sessions. Enjoy!
August 2018: I attended the Microsoft Research Faculty Summit in Redmond, WA. There were many interesting presentations. I was particularly interested by the panel on “Intelligent Edge” that both reviewed Microsoft focus in that area and presented a number of perspectives on the topic. Also of interest was the announcement of the upcoming release of the Open Network Emulator, and of the reintroduction of Microsoft faculty Fellowships. During the Summit I also had a brief “Researcher in the Hall” discussion describing some of the work we are doing at WashU.
July 2018: I attended the 2018 CRA Conference at Snowbird. The conference is held every two years and brings together most of the leadership of the North American computing research community. This year's edition included a number of interesting panels including on teaching faculty, diversity in recruiting, recruiting initiatives and best practices, ranking, etc.
June 2018: I gave a talk at the LINCS 2018 Workshop on the work done with Ph.D. student Jiayi Song titled “Pricing and Bidding Strategies for Cloud Computing Spot Instances.”
June 2018: The paper “Shared or Dedicated Infrastructures? On the Impact of Reprovisioning Ability” co-authored with Soumya Sen, Xinxin Li, and Kartik Hosanagar, was just accepted for publication in MIS Quarterly.
May 2018: I attended the NSF Workshop on Cloud Economics held at Stanford University on May 16-17, 2018. It was an exciting forum on this important topic and a report documenting the outcome of the workshop should be coming out later this year. Thanks to David Irwin (UMass) and Bhuvan Urgaonkar (PennState) for organizing the workshop.
November 2017: The paper “Opinion formation in Ising networks,” co-authored with M.H. Afrasiabi and S. Venkatesh was published in the Online Social Networks and Media Journal (Vol. 5, March 2018, pp. 1-22). The paper offers a possible explanation, arguably using a stylized model, for the emergence of highly polarized partisan's outcomes when party affiliation has a strong influence in how we weigh others opinions.
October2017: The paper titled “A Statistical Exploration of Protocol Adoption.” co-authored with M. Nikkhah, A. Mangal, and C. Dovrolis was published in the IEEE/ACM Transactions on Networking, Vol. 25, No. 5, October 2017. The paper analyzes data from a body of IETF standards (RFCs) to try to identify factors that contribute to the success (or failure) of proposed standards.
Our IPv6 Monitoring project gathered several years of data on IPv6 adoption and tracked basic web performance when accessing web sites over either IPv6 and IPv4 to determine if and why differences were present. Most of the data remains available on the project web site that also boasts a “query” page that allows you to customize the type of data you want to retrieve. (See the project's original introductory presentation -the audio unfortunately only starts about 7 mins into the presentation- given at the Summer 2010 ESCC/Internet2 Joint Techs conference). The project started as a joint project with Comcast and was subsequently supported by an NSF grant that enabled us to better explore the data we were gathering as well as improve the web interface that provides access to the data. The insight derived from the data gathered as part of this project was ultimately documented in a paper titled “Migrating the Internet to IPv6: An exploration of the when and why,” co-authored with M. Nikkhah and published in 2016 in the IEEE/ACM Transactions on Networking.
