Human-Centered Computer Security: Beyond the Desktop

Modern technologies are increasingly capable, interconnected, and used in diverse aspects of our lives. Securing these devices is critical: attackers can leverage their properties to perform attacks with greater ease and at a larger scale, and attacks can result in novel or amplified harms to users and bystanders. It is necessary to approach securing these devices from a human-centric perspective in order to design application-specific security solutions that maximally protect the relevant human assets via defenses of appropriately calibrated costs.

Robotics Open House

As part of National Robotics Week, the Human-Computer Interaction Laboratory proudly hosts an afternoon open house.  Drop in any time between 1 and 4 p.m. (plan on spending 15-45 minutes).  The open house will feature research demos and presentations by the lab and the robot team, including a demo of our humanoid robot, Nao, our Quadcopter, and our telepresence robotics. All members of the public -- including K-12 students, parents and teachers -- are invited to attend, interact with robots and hear about our research.

Security and Privacy for Existing and Emerging Technologies

As our world becomes more computerized and interconnected, computer security and privacy will continue to increase in importance. Addressing security and privacy challenges requires reaching across a broad range of technologies, multiple layers of abstraction, and many aspects of computer science. In this talk, I will focus specifically on two examples of security and privacy challenges that I have addressed in my work by designing and building new systems that better match user expectations.

Strata: A scalable high performance storage system for non-volatile memory

Strata is a commercial storage system designed around the high performance density of PCIe flash storage. We have observe a parallel between the challenges introduced by this emerging flash hardware and the problems we faced with underutilized server hardware about a decade ago. Borrowing ideas from hardware virtualization, we have developed Strata to partition functionality into an object-based address virtualization layer for high performance network-attached flash, and a hosted environment for implementing scalable protocol implementations for heterogeneous clients.

Local Warming

This talk is part of the WID-DOW Collaborative Presentation Series on Doing Optimization at Wisconsin.  Note about location:  Anyone without WID access can use the special events elevator on WID's 1st floor (near Aldo's Café) to access room 3280.
