Computing with Biochemical Circuits Made Easy

02-23-17

Lulu Qian, Assistant Professor of Bioengineering, is working to create circuits using not the usual silicon transistors but strands of DNA. "A DNA circuit could add 'smarts' to chemicals, medicines, or materials by making their functions responsive to the changes in their environments," Qian says. "Importantly, these adaptive functions can be programmed by humans." [Caltech story]

First Artificial Neural Network Created Out of DNA

07-21-11

Lulu Qian, Senior Postdoctoral Scholar in Bioengineering; Erik Winfree, Professor of Computer Science, Computation and Neural Systems, and Bioengineering; and Jehoshua (Shuki) Bruck, Gordon and Betty Moore Professor of Computation and Neural Systems and Electrical Engineering, are the first to have made an artificial neural network out of DNA, creating a circuit of interacting molecules that can recall memories based on incomplete patterns, just as a brain can.

Largest Biochemical Circuit Built Out of Small Synthetic DNA Molecules

06-02-11

Lulu Qian, Senior Postdoctoral Scholar in Bioengineering, and colleagues including Erik Winfree, Professor of Computer Science, Computation and Neural Systems, and Bioengineering, have built the most complex biochemical circuit ever created from scratch made with DNA-based devices in a test tube that are analogous to the electronic transistors on a computer chip."We're trying to borrow the ideas that have had huge success in the electronic world, such as abstract representations of computing operations, programming languages, and compilers, and apply them to the biomolecular world," says Dr. Qian.
