Also reporting to Thrivikraman is Kris Ng, who has rejoined Publicis as head of art after a stint in an independent art-based creative role where she worked alongside clients such as Nokia and Unilever.
The appointments follow the departure of senior creative director Raymond Quah, who has left the agency to pursue a personal interest in designer furniture.
In August, Sam Cassels was named chief executive of Publicis Singapore following the merger of Saatchi & Saatchi with Fallon in Japan. Cassels was formerly head of Saatchi & Saatchi in that market.
