Welcome to the 2019 CCSC Northeastern ConferenceWelcome to West Haven, Connecticut and the University of New Haven,for the Twenty-Fourth Annual Consortium for Computing Sciences in CollegesNortheast Region Conference. The conference is held in cooperation with theACM SIGCSE and Upsilon Pi Epsilon Honor Society.Our program features two distinguished invited speakers, Pete Wurman,Vice President of Engineering at Cogitai and Jia Chen, Offering Leader ofBlockchain Solutions for Healthcare and Life Sciences at IBM’s Innovation andSolution Incubation Team. The conference has a diverse and engaging program that includes paper presentations, lightning and encore talks, workshops,tutorials, and faculty and student research poster presentations. On Fridaymorning, we are hosting our traditional programming contest. On Friday afternoon, we have two student-focused sessions: a student “unconference” and aprogramming problems discussion session to allow participants and organizersof the programming contest to review and analyze problem solutions.Our thanks go to a remarkable conference committee and highly investedboard. Their inspiring and diligent work has ensured the success of this conference. We are also very fortunate to have worked with dedicated and thoroughreviewers, enthusiastic session chairs, and outstanding student and staff volunteers at University of New Haven. The conference continues to be selective;we accepted 9 of 23 papers for an acceptance rate of 39%. This continues toensure the high-quality program of a widely recognized regional conference.We hope you find the conference informative and engaging, meet new colleagues, and get new ideas to contribute to computing education in Northeastern Region. If you are interested in volunteering for our conference, weencourage you to attend the CCSCNE Business Meeting on Saturday afternoon. We also look forward to seeing you next year at Ramapo College of NewJersey.Alice FischerUniversity of New HavenMark HoffmanQuinnipiac UniversityConference Co-chairs11

How Kiva Robots DisruptedWarehousing KeynotePete Wurman, Vice-President of Engineering at CogitaiKiva Systems introduced swarms of agile robots into an industry dominatedby stationary conveyor systems. The path from concept through successfulstartup and eventual acquisition involved challenges on all fronts. Peter Wurman will explain the business problem that motivated the innovation, Kivatechnology and the benefits it brought to customers, and the future of applications of robotics in warehouses.Dr. Pete Wurman, Vice-President of Engineering at Cogitai Pete Wurmanis currently Vice-President of Engineering at Cogitai, an AI startup deliveringreinforcement learning as a service. Pete is best known for his work as a technical co-founder of Kiva Systems, the Boston-based company that pioneered theuse of mobile robotics in warehousing. In May of 2012, Kiva was acquired byAmazon, and has subsequently deployed more than 150,000 robots to Amazondistribution centers. Prior to joining Kiva, Pete was an Associate Professor ofComputer Science at North Carolina State University. Pete earned his Ph.D. inComputer Science from the University of Michigan, and his B.S. in MechanicalEngineering from M.I.T. Copyright14is held by the author/owner.
Transform the Era of Health withBlockchain KeynoteJia Chen, IBM Healthcare SolutionsToday’s healthcare system faces several systemic challenges, including complex/inefficient processes, lack of interoperability, data silos, fraud and lack oftransparency. Blockchain technology has the potential to bring industry widetransformation to the healthcare ecosystem by reducing costs and frictions,bringing more trust and transparency to multiparty transactions, and evenunlocking new sources of revenue for various constituents. We’ll discuss examples of leveraging blockchain technology to enhance the fluidity of healthcareinformation among key stakeholders, leveraging smart contract to reduce administrative costs for value based payment models, and the formation of anopen network to drive digital transformation in the industry.Dr. Jia Chen is an Offering Leader of Blockchain solutions for Hea
