I help run two groups: Sampa on hardware/software systems and MISL on using DNA for information technology applications.
My official UW CSE webpage, and my constantly semi-up-to-date CV.
An overview of our work on approximate computing can be found here. And try out our language, compiler and benchmarking infrastructure for approximate computing.
Check out the videos from my Hardware/Software Interface class.
I work on the intersection of computer architecture, programming languages, operating systems and biology. My goals are explore new ways to build computing systems. I am a proud member of the sampa and MISL groups.

If you need a good architecture simulator, take a look at SESC, a very fast multiprocessor simulator. And here is a good way of choosing your next architecture or compiler conference.
We have released our Grappa runtime system for large-scale irregular applications (e.g., graph analytics), take a look!
We have also recently started publicizing approxbench.org, and ACCEPT, a set of tools and benchmarks for approximate computing research.
Take a look at the collectively written white-paper on 21st Century computer architecture research.
I am lucky to have my research supported by Microsoft, Intel, Google, Qualcomm, NetApp, NSF, and the Pacific Northwest National Laboratory. I am also a member of the Center for Future Architectures Research.I received an NSF CAREER Award and a Microsoft Research Faculty Fellowship to develop ideas on deterministic multiprocessing and multicore programmability in general. I am also the 2013 recipient of the IEEE TCCA Young Computer Architect Award.

I was born in São Paulo, Brazil.
I received my PhD in Computer Science from University of Illinois at Urbana-Champaign. I got my BEng and MEng in Electrical Engineering from University of São Paulo, Brazil.
I love to cook and eat.
I am very fortunate to have such a happy family.
My (much smarter than me) brother was freezing in Michigan but having fun with aerospace engineering, now he is in sunny California at NASA AMES..
I am always happy because she
