Why Biological Circuits Differ From Electronics
- Synthetic circuits face crosstalk, stochastic noise, and nonlinearity unlike electrical circuits with isolated wires and deterministic signals.
- Mustafa recommends stochastic, hybrid models (CTMC plus deterministic parts) when molecule copy numbers are low.
From Theory To A Wet Lab
- Upon starting his lab at ETH, Mustafa learned wet-lab techniques from scratch and expanded from one bench to many experimental teams.
- He values combining theory with experiments to shift from system analysis to actual control synthesis in cells.
Antithetic Integral Feedback Core Idea
- The antithetic motif uses two molecules that bind and neutralize each other to implement integral feedback inside cells.
- This motif proved necessary for robust perfect adaptation under stochastic molecular noise and was implemented experimentally (Nature 2019).
