She's building a hard drive out of DNA.

The world keeps producing more data, and conventional data centres require physical space, electricity and cooling. DNA offers a radically different storage medium: information can be encoded into sequences built from the four chemical bases that biology already uses.

Because DNA is extraordinarily dense and can remain stable for very long periods under the right conditions, researchers see it as a promising medium for archival data—the information we need to preserve but do not access every day.

Anagha Rajesh founded BioCompute to build a full-stack DNA data-storage system. Instead of relying only on expensive de novo DNA synthesis, the team has explored encoding information by editing DNA and retrieving it through nanopore-based reading.

BioCompute reports that it has stored data in DNA, read it back using an Oxford Nanopore sequencer and built an end-to-end working prototype. Its longer-term product vision is an integrated microfluidics chip that can write, read and store information in bacterial DNA.

DNA storage is not ready to replace everyday hard drives. Writing data remains expensive, reading systems require specialised equipment, and the technology must become faster, cheaper and easier to operate at scale.

That is precisely why the build matters. Anagha and her team are competing in a frontier field where the scientific and engineering barriers are global. BioCompute is not simply asking where tomorrow's data will live. It is attempting to manufacture the answer.
