S'pore Poly valedictorian aims to be clinician-scientist after observing doctors at work The TL;DR: Mr Donavan Tan Jia Jie, valedictorian of Singapore Polytechnic's Chemical and Life Sciences cohort, e-mailed over 300 doctors for job-shadowing opportunities. More than 10 said yes, sparking his ambition to become a clinician-scientist.
Between December 2022 and January 2023, Singapore Polytechnic (SP) biomedical science student Donavan Tan Jia Jie e-mailed more than 300 doctors individually asking them if he could shadow them at work to gain first-hand insight into the profession.
Thirteen of them said yes. F rom February to April 2023, Mr Tan rotated through more than six medical specialities, including general medicine, neurosurgery, palliative medicine, and oncology, spending two to five days at each placement, typically from 8am to 6pm.
His behind-the-scenes look at life as a doctor inspired him to want to study medicine at the National University of Singapore (NUS).
The soon-to-be 20-year-old recently graduated from SP with a perfect 4.0 grade point average (GPA) and was awarded the prestigious Lee Kuan Yew Award, which is presented to outstanding course gold medallists from technology or computer-related disciplines at each of the polytechnics.
He has applied for deferment from national service to study medicine at the National University of Singapore, where he has been offered a place.
Looking back at his experience of observing doctors at work, he said one moment stood out. At the National Cancer Centre, he met a teenage patient, not much older than himself, who was diagnosed with an incurable form of cancer .
'It was difficult for me, because he was someone around my age, a teenager who hadn't had the chance to fully experience life, to pursue his passions, start a family or contribute to society,' Mr Tan said.
'He had a prognosis of less than a year.'
That experience ignited a sense of purpose in him – what began as a passing interest in medicine became a committed pursuit of oncology.
His final-year project was a seven -month research on breast cancer at NUS Medicine.
'I realised I wanted to do more for patients like him, to help them live their lives to the fullest,' said Mr Tan, who was a research intern at the Cancer Discovery Hub, National Cancer Centre Singapore from March to May 2025.
'The path to medicine definitely hasn't been easy,' he said. 'But what kept me going is knowing that, soon, I will have the opportunity to make a lasting positive impact on the community around me.'
One of Mr Tan's lecturers, Mr Goh Tong Hng, also guided him to consider medicine as a career, as well as regularly checked in on his academic progress, offered advice, and helped him prepare for interviews.
After graduating from SP, Mr Donavan Tan worked as a research intern at the Cancer Discovery Hub, National Cancer Centre Singapore.

Mr Goh 'was always there not just as a lecturer, but as a mentor', he said.
Mr Tan, who achieved an L1R5 (raw) score of 7 at O levels, chose the polytechnic path for its practical learning and specialised curriculum, even though it meant a more challenging route to university.
To bolster his application to study medicine at NUS, he also volunteered for community work.
At Presbyterian Community Services, he connected with elderly residents living alone. At Meet-the-People sessions in West Coast-Jurong West GRC, he assisted residents in drafting case letters to agencies, gaining exposure to the struggles faced by underprivileged families .
Under the Family of Purple Heart programme, which supports caregivers' emotional and mental well-being, he managed volunteers and coordinated outreach efforts.
'I wasn't sure where my interests truly lay, so I wanted to cover as many aspects of society as possible,' he said. 'Each experience touched a different need in the community, and I was keeping an open mind about where I could make the most impact.'
Mr Donavan Tan did his final-year project and internship at the Department of Pharmacology, NUS Medicine, helping to develop targeted treatments for an aggressive type of breast cancer.

His dedication was recognised when he was awarded the SP service-learning award for two consecutive years, in recognition of his commitment to supporting vulnerable and underprivileged communities through active engagement in service projects.
While he acknowledged the importance of a strong portfolio, he said his community involvement stemmed from a genuine desire to serve, not just to impress medical school interviewers.
'I did all these because I genuinely wanted to do something meaningful for the community,' said Mr Tan.
He said: 'For me, it's always been about the bigger picture.'
'I want to do good with my life, not just for myself but for others as well. Medicine offers me the best opportunity to have a lasting, positive impact on the community.'

Six endangered fish species found in fish maw from Singapore and Malaysia's stores: Study
Around 500 samples of fish maw were collected from stores across Singapore and Malaysia, and sent for DNA analysis. PHOTO: SEAH YING GIAT Six endangered fish species found in fish maw from Singapore and Malaysia's stores: Study SINGAPORE - The DNA of six endangered fish species was found in fish maw products from stores in Singapore and Malaysia, a new study found. This was uncovered by a pair of researchers from the National University of Singapore (NUS) and Universiti Malaysia Terengganu (UMT) , who analysed the DNA of 480 samples of fish maw. The duo published their research on June 24 , in the journal Conservation Letters . Fish maw - a delicacy in Chinese cuisine - is derived from the dried swim bladder of fish. Also known as the air or gas bladder, the organ helps fish modulate their buoyancy, allowing them to remain at a desired depth without floating or sinking. Widely consumed throughout much of East and South-east Asia, fish maw is regarded as an indicator of wealth, prestige and status in Chinese culture. It is also a popular ingredient in stews and soups, as it brings purported health benefits. The mysterious origins of fish maw The trade of fish maw products is hard to regulate, however, as it is difficult to visually identify them by species, said NUS Assistant Professor Benjamin Wainwright , one of the study's authors. He said: 'Fish maw has been processed, flattened, cleaned and washed. 'You can't determine what species the maw comes from without using genetic methods - so we have no idea of what species are involved in this trade in South-east Asia.' The aggregation of fish maw and other dried fish products under a common commodity code has also made its trade harder to oversee. Asst Prof Wainwright said: 'Commodity codes are meant to say, this is shark fin, this is shrimp, this is fish maw - but at the moment, all these products are lumped together and imported as dried fish goods.' As such, the two researchers - UMT's Dr Seah Ying Giat and Asst Prof Wainwright - set out to collect fish maw samples from stores in Malaysia between October and December 2023 , and in Singapore from January to April 2024 . Within the Republic, they visited dried goods shops such as those in Victoria Wholesale Centre and Albert Centre , Asst Prof Wainwright said. 'Just from walking around Chinatown, you can see maw everywhere - sold in lots and lots of shops. In supermarkets, there's fried maw all over the place as well.' DNA was successfully analysed from 118 samples from Malaysia and 362 samples from Singapore , and a total of 39 fish species were identified across both countries. The most commonly identified species was the blackspotted croaker (Protonibea diacanthus) , which made up 58 of the 480 samples. It is classified as near threatened on the International Union for Conservation of Nature (IUCN) Red List , which outlines the conservation status of animals, plants and fungi. This means that though the species is currently not threatened by extinction, it is likely to become endangered in the near future. Among the maw samples, there were also four endangered, and two critically endangered species as per the IUCN Red List. The endangered species identified were: the cassava croaker (Pseudotolithus senegalensis) , American eel (Anguilla rostrata) , fourfinger threadfin (Eleutheronema tetradactylum) and iridescent shark (Pangasianodon hypophthalmus) . Additionally, maw samples were also found to originate from the large yellow croaker (Larimichthys crocea) and European eel (Anguilla anguilla) , which are critically endangered. Notably, 11 samples of fish maw were identified as the European eel, despite the European Union's enactment of a zero-export quota on the fish in 2010 , which bars its export from the region. On this, Asst Prof Wainwright said: 'It's not that surprising that eel maw has been sold, because you can find the eels here. 'But it's interesting that the European eel is still making it here, because that should have been banned a long time ago.' Consider more sustainable alternatives Ultimately, as fish maw products often do not specify the exact species used, it may be difficult for consumers to make informed choices, said Mr Chester Gan, the Marine lead at the World Wide Fund for Nature (WWF) Singapore . Businesses and corporations hence play a vital role, he added, and should examine their supply chains to ensure they are sourcing ingredients responsibly and reducing environmental impact. He said: 'Given that fish maw may originate from fisheries with little data, endangered species, or unsustainable fishing practices that harm vulnerable marine life, we urge both consumers and businesses to consider more sustainable alternatives.' To Asst Prof Wainwright, the best option is to not consume fish maw, especially if its species, country of origin and the sustainability of the maw fishery it is from cannot be confirmed. He said: ' The hope is, as more people become aware of the damage caused by unsustainable fishing, they may turn away from products of unknown origin and towards seafood from sustainable fisheries . ' Otherwise, when a species targeted for fish maw gets fished out, it's very likely we'll turn to another species and fish that one out, and then do the same for the next ones .'

Polyclinic patients to trial AI tool that reads heart rate and blood pressure with just a phone camera
By analysing a 30-second video of a user's face, the tool is able to detect levels of blood flow in specific facial regions such as the forehead, cheeks and nose. PHOTO: SINGHEALTH POLYCLINICS Polyclinic patients to trial AI tool that reads heart rate and blood pressure with just a phone camera SINGAPORE - An artificial intelligence tool that allows people to measure their heart rate and blood pressure with just a phone camera will be tested by a group of polyclinic patients in the coming months. DeepHealthVision, developed by South Korean digital health company injewelme, will be trialled here in collaboration with SingHealth Polyclinics (SHP). By analysing a 30-second video of a user's face, the tool can detect levels of blood flow in specific facial regions such as the forehead, cheeks and nose, producing accurate readings of both heart rate and blood pressure without the need for external medical devices such as blood pressure monitors and oximeters. 'For example, someone who has high blood pressure or heart rate commonly presents with flushed skin,' said injewelme's chief business development officer Nathan Cheong on June 20, at the 10th Asia Pacific Primary Care Research Conference 2025 held at Academia at the Singapore General Hospital Campus. The accuracy of measurement is not affected by skin colour, he added. Apart from phones, patients can also use the cameras in other devices such as laptops and tablets. Clinical Associate Professor Tan Ngiap Chuan, director of research and Primary Care Research Institute at SHP, said this would make healthcare monitoring more accessible and convenient by eliminating the need for expensive medical devices and frequent clinic visits. A check by The Straits Times found that digital blood pressure monitors can cost anywhere between $50 and $300. 'This system also facilitates continuous remote health monitoring, allowing healthcare professionals to detect health issues before they become serious, enable earlier intervention, and potentially reducing hospitalisations,' said Prof Tan. Mr Cheong said there are also plans to integrate injewelme's AI prediction model DeepHealthNet into DeepHealthVision, which would allow healthcare professionals to access patients' vital signs so that they can make more informed clinical decisions, instead of relying only on limited information collected during visits to the doctor. More than 100,000 people in South Korea have tested out DeepHealthVision, while around 30 healthcare professionals in Singapore were able to try their hand at it during a recent live demonstration . During the demonstration here, the accuracy of DeepHealthVision's heart rate and blood pressure readings was around 96 per cent, when compared with readings taken by Omron blood pressure monitors or Samsung Galaxy smartwatches, said Mr Cheong. Prof Tan said around 60 polyclinic patients will be involved in the pilot test of this tool in the coming months, which would include those with and without hypertension, and others who are interested in knowing more about their own vascular health. He said: 'We want to find out whether local patients are confident in using the technology, whether they accept it, and if they have any concerns. Because if they have concerns, they might not use it on a regular basis.' The pilot test is expected to run for at least a year, during which the data collected will be analysed and subjected to peer review. If the trial is successful, DeepHealthVision may be integrated into healthcare apps such as Health Buddy in the future. The team is also working to enable blood glucose monitoring and skin analysis down the line. In May, SHP also signed memorandums of understanding with two other South Korean companies, YoungAnd and Monit. SHP is collaborating with YoungAnd on Brain Health Playground, an interactive platform designed for patients to play games that support cognitive function. SHP will also trial a tool developed by Monit to assess diaper contamination levels with the use of sensors and an AI-driven pattern learning algorithm.
