I am a Ph.D. student at Northeastern University working under Alan Mislove. My research interests currently lie in the area of cloud computing, network systems and social networks.
- 11/07/14 I presented our measurement study about SSL and Heartbleed on IMC 2014.
- 07/31/13 Our paper on Priv.io (a new privacy-preserving social network architecture) was accepted at COSN 2013!
- 01/08/13 Our Maygh paper on building CDNs from web browsers was accepted at EuroSys 2013!
- 09/01/12 Do you want to take full control of your personal data in the cloud? Try Priv.io now!
- 06/05/12 Our paper on WebCloud was accepted to IEEE NCA 2012!
- 10/15/10 Try my Forward Kinematics and Inverse Kinematics demo.
- 09/10/10 Our WebCloud system for serving Facebook content using web clients is available.
- 12/14/09 Feel boring in hospital waiting room? We would like to introduce you WRAP.
- Priv.io: Priv.io represents a new way of architecting Web-based content-sharing services like Twitter, Facebook, and Tumblr. Today all of these sites work by providing service to you, the end user, for free. To pay the bills, the respective companies are forced to sell advertising. Unfortunately, this advertising isn't just annoying, it is potentially the source of privacy leaks of your data to third-parties.
In Priv.io, we build a federated web site by having each user continue and pay for the storage and bandwidth required to serve their content. In other words, your content is served by the service that you designate, while your friends' content may be served by a different service. Priv.io uses encryption to ensure that people can only view what you allow them to (and even your service provider cannot view your content). Even with the dramatically different architecture, the service looks just like a normal web site.
- Relational Agent: A relational agent is an embodied conversational agent that displays a human character on the screen to build and maintain long-term, social-emotional relationships with people. In this project, I focus on creating the software program that provides the essential functionalities to support different research projects.
- LensList: Lists are simple and useful graphical user interface (GUI) component for organizing linearly structured information, and work best when they contain only a few elements. However, long lists are difficult to use because only a small part of the list is shown at any time; to gain an overview or select elements from a long list, the user usually needs to scroll the list many times. To address this concern, we applied the focus and context technique (also known as the fisheye effect) to the view of a list.
