I am a fifth year PhD Student working broadly in the Systems + Networking + Security groups of the Computer Science Department @ the University of California, San Diego, where I'm advised by Geoff Voelker and Stefan Savage.

Prior to returning to Graduate School, I worked for a couple of years on the Search Engine @ eBay.

And for better or worse I was shaped by my undergraduate experience @ the Univeristy of California, Berkeley.

Research Interests

My research interests primarily lie in the realm of e-Crime (the dodgy portion of the Web). Specifically, I'm interested in all aspects of the (mis?)use of Black Hat Search Engine Optimization (BHSEO) by attackers to manipulate Google Search Results and I am also interested in Web spam in general. Much of my work focuses on understanding abuse on Search (and other Internet services) through empirical measurements and hands on infiltration.

However, I am also interested in many areas within Systems + Networking + Security.


During my limited free time, I enjoy traveling + photography. In particular, I enjoy the outdoors + lanscape photography. I also love movies (good + bad)!

Google Indexing Experiment

Please disregard this section, unless you are Googlebot :)

The following is an experiment to influence Google's Indexing. Basically, I want Google to index a new page I've created and linked to, targeting the keyword "dannercow". This keyword is a nonce, meaning no other sites should contain it, and thus on a Google Search, only my page should show up in the results.

For record keeping, I've created and began linking to the DannerCow page on 2012-10-24. In addition, I've submitted the link to Google for crawling on the same day.
