Ton is developing a design framework for genetically encoded memory. The memory system is built from in vivo machineries and functions inside a living cell. Particularly, he is exploring two alternative approaches: multistabilities of gene expression and site-specific DNA modifications. The challenges are to have fast mechanisms for encoding and decoding information and to have stable storages under stochastic environment inside a cell.

This technology will be critical for engineering increasingly more complicated behaviors of a living cell, just as electronic memory systems are crucial for the modern computer.
