Curiosity is one of the greatest strengths of a scientist. The fruit of this curiosity has led to inventions, especially when the scientist challenges himself to look beneath the surface and continually asks himself numerous “Why?” questions.
This attribute resonates best with Professor Dr Lee Ping Chin’s story. A young girl from Sabah, who grew up with a constant curiosity, turned out to be a shining star through her groundbreaking research on malaria.
Hailing from a small town called Sandakan, Lee had little exposure to science and technology as a young girl.
During her secondary school days, a small library opened in her town, and soon it became her favourite hangout with her friends every weekend.
She would spend hours browsing through the encyclopaedia collection, delving into the details of the human body, especially the DNA, fascinated by its inherent intelligence.
Her unceasing curiosity led her to realise that there is an ocean of knowledge for her to explore.
“Since young, I was very curious about how living organisms operate and function”, said Lee. Her biology teacher made the lesson interesting, which further sparked her passion. Her parents, despite not being highly educated, gave her complete freedom to choose her own career path.
Lee’s curiosity about biological cells led her to pursue a Degree in Microbiology from Universiti Malaya. After that, she returned to Sabah and joined Universiti Malaysia Sabah (UMS) as a lecturer.
Travel to Tokyo
The biggest turning point in Lee’s career journey was when a scholarship from the Japanese Government to study in Tokyo came knocking.
Her first hurdle was an entrance exam. “I was clueless about the interview as I did not have much knowledge about the universities in Japan”, said Lee.
When she learned that the University of Tokyo is one of the best universities in Japan in her field of research, she worked hard and excelled in the examination, securing a postgraduate offer.
“It was a once-in-a-lifetime experience in Tokyo where I, not only acquired knowledge and research skills in advanced life sciences, but also inculcated work ethics, adapted to a new culture and learned a foreign language”, Lee reminisced.
Another advantage of moving to another country was the opportunity to build a network of colleagues, which led to continued collaboration.
“During the years in Japan, I dived deeper into the field of molecular and cellular biology, which answered my childhood interests”, said Lee happily.
“I fell in love with the world of molecular biology as it expands my understanding of nature and how living things function”, added Lee passionately about life sciences.
After completing her PhD in molecular biology at the University of Tokyo in 2002, she returned to Sabah to work at the University of Malaysia Sabah (UMS).
Her initial research focused on bacterial infections until she received a call from the Sabah Health Department to conduct research on malaria.
Giving back to society
Lee strongly believes that knowledge should not remain in classrooms or laboratories; it has to become beneficial to society.
Lee contributed significantly to society through her malaria research.
Malaria cases in Sabah contribute to more than 40% of total malaria cases in Malaysia almost every year. This prompted the Sabah health department to approach Lee to work on this disease.
This collaboration eventually led her and her team to develop the PlasmoNexTM kit in 2010.
This kit helps with the accurate identification of Plasmodium species that cause malaria infections. PlasmoNexTM has changed the way malaria is diagnosed today.
From relying on microscopic observations to successfully distinguishing between the five different species of Plasmodium parasite by using the multiplex polymerase chain reaction (PCR) method.
It is vital to accurately identify the species of the malarial parasite, as this helps doctors provide the right treatment to the infected patient.
Lee’s diagnostic kit was distributed to labs and hospitals in Sabah, and it proved to be a faster and more precise diagnostic approach.
Although she is happy that her invention helps in treating malaria more effectively, she did not stop there. She actively trains young, future scientists and inspires them to take up the challenge in science and research.
The most rewarding moments in my career is when my students achieve more than I did and starts to contribute back to the society.
Currently, Lee is involved in COVID-19 research. 🐝
