Daren Shiau, PBM, is Head of Competition & Antitrust at Allen & Gledhill LLP. He is a competition law specialist, and his practice covers antitrust litigation, international cartels, merger control and sectoral competition regimes.

Cited as the “most highly nominated practitioner” and “a real expert, according to rivals” in the inaugural Competition chapter of Who’s Who Legal: Singapore (2008), Daren has also been recommended as a leading antitrust practitioner in The International Who’s Who of Competition Lawyers and Economists and the Euromoney Guide to the World’s Leading Competition and Antitrust Lawyers since 2006 when Singapore’s competition law was enacted.

In 2012, Daren was named one of the world’s most talented competition lawyers under the age of forty by Global Competition Review: 40 Under Forty, and considered in Who’s Who Legal 100 2013 to be “very skilled” and "one of the finest antitrust lawyers in the region".
