Recent news reports stated that the National Security Agency has pursued new methods that have allowed the agency to monitor telephone and online communication, encrypted information that was thought to be virtually immune to eavesdropping. What steps can and should computer scientists take in response to this privacy threat? How will the recent revelations affect the future of cryptography—the field of encoding and decoding electronic communication and transmissions for the purposes of privacy, reliability and efficiency?
To address these questions, the Johns Hopkins University Information Security Institute will host an hour-long roundtable discussion, moderated by Anton Dahbura, interim executive director of the Information Security Institute, and Avi Rubin, the institute’s technical director. Other participants will include Johns Hopkins cyber-security experts Matthew Green, Stephen Checkoway and Giuseppe Ateniese.
The event will be streamed live at https://connect.johnshopkins.edu/jhuisicrypto/, and also will be posted online following the event.
NOTE: Seating at this public event will be limited. Members of the media who plan to cover the discussion are asked to RSVP to Phil Sneiderman, firstname.lastname@example.org.
From 3 to 5 p.m. on Friday, Feb. 5 at the Hopkins Club, the Whiting School of Engineering will celebrate two milestones:
RSVP by February 2.
Ilya Shpitser, in the Department of Computer Science, will hold the John C. Malone Assistant Professorship, one of a series of professorships provided by John C. Malone, MS ’64, PhD ’69 to help recruit and retain faculty with the goal of improving healthcare using a systems-based approach. A data/inference specialist who focuses on inferring cause-effect relationships, Ilya will be a member of the new center. His research includes all areas of causal inference and missing data, particularly using graphical models. Recently, his work has helped distinguish between causation and association in observational medical data. Ilya started at Johns Hopkins as an assistant professor this summer, received his PhD under the supervision of Judea Pearl at UCLA, was a postdoctoral scholar in the program on causal inference at the School of Public Health at Harvard, and was a lecturer in statistics at the University of Southampton.
The Malone Center for Engineering in Healthcare, under the leadership of Greg Hager, the Mandell Bellmore Professor in the Department of Computer Science, is a multidisciplinary research initiative that will foster partnerships among engineers, clinicians, and scientists across Johns Hopkins University to catalyze, develop, and deploy innovations aimed at improving the efficiency and effectiveness of healthcare.
John Malone has been remarkably generous in his support of Johns Hopkins, including a gift for the construction and naming of Malone Hall. The building, which opened in 2014, is designed to advance cutting-edge collaborative and translational research and has set a new standard for academic research facilities at Johns Hopkins. The Whiting School is grateful for Dr. Malone’s continued support of professorships and the naming of this new center in the Whiting School of Engineering.

Towards Understanding and Proactively Dealing with Failures in Modern Systems
Many of the services we use everyday now run in data centers or mobile devices. However, building systems in these modern platforms to provide reliable services is difficult. This is evidenced by the fact that despite the large amount of work put into system quality assurance, all modern systems continue to experience million-dollar outages and frustrating anomalies like battery drain.
In this talk, Huang will describe my research efforts to better understand and proactively tackle the reliability challenges in modern systems. First, he will discuss work that looks into failures in cloud services. Instead of focusing on conventional root-cause analysis, this work takes a unique angle to examine the fault-tolerance mechanisms in cloud, and analyze why they did not prevent the service failures. He will summarize several challenges (opportunities) for reducing these failures in the future. One such challenge is system configuration: existing fault-tolerance techniques often cannot tolerate (or worse are nullified by) configuration errors, and misconfiguration becomes a major source of cloud outages. He will then present work that enables cloud practitioners to proactively prevent configuration error by using a systematic validation framework. The framework consists of a declarative language for developer/operator to express configuration specification, a service that continuously checks if configuration obeys its specification, and a tool that automatically infers basic specification. He will also touch on the challenge of app misbehavior in mobile ecosystem and proactive prevention at runtime by making mobile OS defensive.
Peng (Ryan) Huang is a Ph.D. candidate at UC San Diego advised by Professor Yuanyuan Zhou. His research interests intersect systems, software engineering and programming languages. He is particularly interested in understanding rising problems in real-world systems and reflecting that understanding in new techniques to improve system dependability. His work has been applied in industry including Microsoft and Teradata, and deployed to many real users. He is currently a part-time contractor with Facebook doing research on configuration management. Peng received his MS from UC San Diego in 2013, and his BS in computer science and BA in economics from Peking University in 2010.
Bilge Mutlu, University of Wisconsin-Madison, will present “Human-Centered Principles and Methods for Designing Robotic Technologies, at 11 a.m. in Hackerman Hall B-17, on the Johns Hopkins University’s Homewood campus.
Abstract: The increasing emergence of robotic technologies that serve as automated tools, assistants, and collaborators promises tremendous benefits in everyday settings from the home to healthcare, manufacturing, and educational facilities. While these technologies promise interactions that can be highly complex and beneficial, their successful integration into the human environment ultimately requires these interactions to also be natural and intuitive. To achieve complex but intuitive interactions, designers and developers must simultaneously understand and address human and computational challenges. In this talk, I will present my group’s work on building human-centered guidelines, methods, and tools to address these challenges in order to facilitate the design of robotic technologies that are more effective, intuitive, acceptable, and even enjoyable through successful integration into the human environment. The first part of the talk will review a series of projects that will demonstrate how the marrying of knowledge about people and computational methods through a systematic design process can enable effective user interactions with social, assistive, and telepresence robots. The second part of the talk will cover ongoing work that provides designers and developers with tools to apply these guidelines to the development of real-world robotic technologies and that utilizes partnerships with domain experts and end users to ensure the successful integration of these technologies into everyday settings through applications in healthcare, manufacturing, mission-critical environments, and the home. The talk will conclude with a discussion of high-level design guidelines that can be drawn from this body of work and a roadmap for future research.
Speaker bio: Bilge Mutlu is an associate professor of computer science, psychology, and industrial engineering at the University of Wisconsin–Madison.
