We congratulate Hans Buehler on his transformational contribution to deep hedging and data-driven methods to option pricing.
It was wonderful news to read in Risk.net that Buehler has been named Quant of the Year in the 2022 Risk Awards. Relevant to the readership of this website, is that signatures have played a key underpinning role in his work. In an extended description of his contribution, in Risk.net:
