South African Observatory Director
About George Van der Merwe
In 2018, George Van der Merwe led the integration of MeerKAT’s first 32 dishes into a coherent array while simultaneously negotiating land-use agreements with eight rural municipalities, ensuring radio-quiet zones without displacing communities. His approach fused technical rigour with deep sociotechnical awareness: he co-designed the Karoo Array Telescope’s calibration protocols using local meteorological data to compensate for ionospheric distortion unique to the Northern Cape’s high-altitude desert. Unlike peers who prioritised scale over sustainability, he mandated that all observatory power infrastructure be solar-hybrid before commissioning, reducing grid dependency by 67% during peak observation cycles. He doesn’t speak of ‘big data’ but of ‘listening discipline’, a phrase he coined to describe how signal processing must account for both galactic noise and the cultural rhythms of the San-speaking communities whose ancestral lands host the dishes. His office wall holds not awards, but a hand-drawn map of groundwater aquifers beneath the telescope sites, annotated in Afrikaans and !Xun.
