That's a lot of different research directions. But I didn't see P systems mentioned. Maybe because P systems are a model of computation studied by computer scientists that assumably isn't currently implementable? There are many variants, but the basic model is of set a compartments (e.g. cells) which contain signalling chemicals which can be synthesised, destroyed, or passed between adjacent compartments according to rules. A number of P system algorithms have been developed such as leader election and graph diameter calculation (of the adjacency graph). Seems very difficult to program. https://en.wikipedia.org/wiki/P_system https://en.wikipedia.org/wiki/P_system
