In 2013, the latest year for which Organisation for Economic Cooperation and Development figures were available, similar ratios in France and Germany were 25 per cent and 28 per cent respectively.
Research scientist Sharon Nai, 39, who holds a PhD in mechanical engineering and leads a team at A*Star researching on 3D additive manufacturing, said she has seen more female interns seeking attachments, something she welcomes.
"The ratio of males to females should not be a hindrance, it is about having passion for the job," she told The Straits Times.
This is what has kept her in this industry since she joined A*Star's Singapore Institute of Manufacturing Technology in 2002. "In this field of research, I get to engage the related industries. Being able to contribute is something I value," she added.
Research scientist Tan Yen Nee, 35, agrees. One of the projects she is working on at A*Star's Institute of Materials Research and Engineering can accelerate the process of discovery for new anti-cancer drugs.
"I am happy to do research that can be translated into something beneficial for our society," she said.
Dr Tan, who holds a PhD in molecular engineering of the biological and chemical systems and is an adjunct assistant professor at National University of Singapore, said more female students have requested internships or visits to the lab.
But Dr Tan, a mother of two, said there are challenges specific to women scientists like herself, like being more careful during pregnancy. "I was a bit clumsier when I was pregnant and we do work with some dangerous chemicals in the lab," she said, adding though that using personal protective equipment is sufficient.
She believes that role models in the science arena should step forward to mentor and encourage younger women to pursue careers.
She said: "It can be difficult, but as women, we can endure and embrace the challenges."
