Before joining Northeastern, I was a postdoctoral research associate in Tom Anderson. S group at the University of Washington. This work has been generously funded by the CI Fellows. Program. I earned my PhD in Computer Science from Northwestern University in June, 2010, where I was awarded two Cabell Fellowships and 2009/2010 Outstanding Dissertation in EECS. Prior to that, I graduated from Amherst College. Saw fit to entertain this notion. Also available as a PDF. 202 West Village H. Boston, MA, USA.

The Internet has grown to reach a wide range of devices such phones, cars and televisions, but our ability to measure, optimize and evolve these increasingly complex networks has not kept pace. As a result, we have networks that continue to experience frequent failures and deliver suboptimal performance. First, my work crowdsources measurement and performance evaluation of Internet systems by deploying software to users at the scale of tens or hundreds of thousands of users. To date, more than 1 mill...

Services - ReCon: Take Control of Your Mobile Privacy: Services Provided
https://recon.meddle.mobi/services.html
What can ReCon do for me? Nearly every time you access the Internet, some hidden company is quietly gathering information about you without your explicit consent. This includes where you are, what Web sites you are visiting, and even you real name, gender, or sexual orientation. We believe that this continues to occur because today's phones give us no visibility. Into what information is being sent, and no control. Over personal information sent over the network. ReCon shows you which sites are gathering...

All posts by choffnes. The Curious Case of the Exposed Password. March 3, 2016. David Choffnes, Northeastern University (choffnes@ccs.neu.edu). Researchers at Northeastern University identified more than 20 iOS, Android, and Windows Phone apps that exposed users’ credentials, including. We started with a simple idea: identify how much of users’ personal information is exposed over the Internet when using mobile apps, and allow users to do something about it. This idea led us to create the. Perhaps the mo...
