Think Tanks do more than just research. At CSTEP, it is the coming together of science and policy practitioners, modellers, and communicators with a single mandate: bringing forth scientific evidence to improve policy to tackle developmental challenges. In this series, we look at what happens behind the scenes at a technology-policy think tank, and how each link in the chain plays a crucial role. In the first blog of the series, Devaditya Bhattacharya, Editor, CSTEP talks about how copy-editing is more than a simple grammar check at a think tank and how adding value is a key mandate of the job.
