A Conversation with Yang Dan.

Dr. Dan: Absolutely. Both things that you said are crucial for our research program. Optogenetics is crucial. Without it, I probably would never have even moved into sleep. Because that tool was available and I started using it in the visual system, I realized how powerful it is and I see this new opportunity to apply it to sleep research. More recently, we’ve also been doing a lot of sequencing, gene profiling. Without it being cheap, we would not be able to afford it.
