Thanks for dropping by. I haven't updated this part of the site in a very long time, so I thought I'd post a quick one:

In mid-2012 I moved to the U.S. to work at Ettus Research where I could continue experimenting with Software Defined Radio, and am currently the "Applications Specialist and SDR Evangelist".


I like to spread the word about SDR. For example: I will be speaking at Black Hat US 14, I have spoken at DEF CON 21, Ruxcon 2011, and the past few GNU Radio Conferences. Some other fun experiences include delivering a week-long SDR lab at the School on TV Whitespaces/SDR Workshop held at the ICTP, Trieste, Italy in early 2014, a talk at an iSec Open Forum evening, and a lecture to EE-123 students at UC Berkeley. For a complete list, check out the Presentations wiki page.

I'm fortunate enough to be helping out the ISEE-3 Reboot Mission as the 'radio guy' (Communications Engineer), part of the Mission Control team. I oversaw the set up and use of USRPs at the Arecibo Radio Observatory to make first contact with the space probe after 36 years, and now do the same remotely for each of our 'supports'.
