I work on programmability and debugging of deep neural networks. Systems should be transparent to the people who use them.

My work investigates the following questions.

  • Can latent knowledge within deep neural networks be cleanly identified, debugged, encapsulated, and reused?
  • Can tools be created to allow programmers to effectively debug and design deep neural networks?

I am also interested in programming tools that make computer science more accessible to beginners and non-expert programmers. I believe that the technologies created by humanity should be programmable by all.

Background

Industry Prior to starting at MIT, I worked in the software industry for 18 years, where I contributed to several widely used projects. At Google I was a staff software engineer on Google Image Search and Google Talk. At Microsoft I helped create Microsoft Internet Explorer and ASP.NET. At the startup Crossgain I helped create the Weblogic Workshop IDE. I have created several open-source projects including XMLBeans, seedrandom.js, and a and a variety of other hacks.
Pencil Code Together with my son I created Pencil Code, a programming tool for beginners that introduces several innovations that bridge the gap between beginner coding and mainstream programming. It has a block code editor that smoothly bridges to text, and it includes a turtle graphics environment that smoothly bridges to mainstream web programming. The system helps students transition to text-based programming remarkably quickly; I have published several papers about the system, its components, and its efficacy.
Numerical Linear Algebra I am coauthor of the textbook Numerical Linear Algebra, with Nick Trefethen, which I wrote while I was at Cornell. It provides a conceptual, mathematical introduction to the field. If you would like a principled overview of the fundamental algorithms behind Matlab, or if you are worried about things like the stability, conditioning, or the precision of floating-point arithmetic in your large matrix algorithms, the book is worth a read.
Academics I have an M.S. in Computer Science from Cornell, and an A.B. in Mathematics from Harvard.
