Research Interests

I work mostly in theory and partially in experiments involving molecular programming, DNA nanotechnology, and algorithmic self-assembly.

Cells provide proof of principle that complex information processing happens in chemistry. We view chemistry through the lens of computer science to understand how. This understanding allows the engineering of molecular systems that compute. Currently, we use this approach to build computers out of DNA molecules (Watson-Crick pairing makes them programmable) as proofs of principle (and with some near-term applications). In the future we will find the best substrates for rationally designed molecular computers for applications like smart drugs, control of molecular factories, diagnostics, and more--wetware for places that electronic microcontrollers cannot go.
