I help run three groups: Sampa on hardware/software systems, SAMPL on machine learning systems and architecture, and MISL on using DNA for information technology applications.

My official UW CSE webpage, and my perpetually 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
Take a look at TVM, our recently-released end-to-end stack for deep learning - tvm.ai.

Research

flower

I work on the intersection of computer architecture, programming languages, machine learning and biology. My goals are explore new and better ways to build computing systems.

About me

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.

Self portraits.

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 lives just a few miles away!

I am always happy because she exists.
