Stephen P. Tarzia: software engineer

welcome!

Stephen Tarzia

You have reached Stephen P. Tarzia's web space. I publish Gun Memorial and I am a Professional Fellow at the Knight Lab at Northwestern University.

Previously, I worked as an engineering manager, a product manager, and as a senior software engineer a various startups in Chicago (see my resume for details).

I completed a Ph.D. program at Northwestern University in August of 2011 in the Electrical Engineering and Computer Science department. My advisor was Professor Peter Dinda, and I worked on mobile systems, with an emphasis on acoustic sensing. My other interests include music technology, operating systems, electronics design automation, optimization algorithms, Internet telephony, embedded systems, architectural acoustics and high-performance computing.

My graduate work was funded by Northwestern University through various fellowships and through my advisors' National Science Foundation grants.

@kaylaVRGL You're right that media coverage of gun violence is biased. We're trying to change that at t.co/c5JO1XvCvq #gpcall

Didn't realize the "zinc lobby" kept the US penny alive. I always assumed credit card lobbyists were to blame. t.co/gGsdkKw63m

@gunsandcoffee12 Suggestions? "People killed by guns" is too long. Maybe "fatal shootings"? I'm still thinking "gun deaths" is best term.
