When Professor Woo Keng Thye conducted clinical research on kidney disease here over 30 years ago, he had to collaborate with his former teachers in Melbourne for his work to be published.
"Our labs were not recognised, our work was not recognised," said Prof Woo, an emeritus consultant in renal medicine at Singapore General Hospital.
Decades later, things could not be more different. He said: "Today, if you look at us, we are world class."
Prof Woo is among researchers whose work is featured in a commemorative book launched yesterday by Minister of State for Health Lam Pin Min at a clinical research conference.
