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.

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.'

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.

askST Jobs: Dispel thoughts of work after hours with these tips
Ongoing interpersonal tensions, high workloads or lack of clarity in your job can create a 'lingering cognitive load' even after work hours. ST ILLUSTRATION: LEE YU HUI askST Jobs: Dispel thoughts of work after hours with these tips Manpower correspondent Tay Hong Yi offers practical answers to candid questions on navigating workplace challenges and getting ahead in your career. Get more tips by signing up to The Straits Times' Headstart newsletter. Q: I find it hard to let go of work outside of office hours. What strategies would be helpful? A: Both personal factors and those related to the work environment can give rise to this feeling, says Dr Al Au, an organisational psychologist. 'Some people tend to prioritise work excessively or define themselves primarily by the work they do,' says Dr Au, a senior lecturer with the National University of Singapore. They may also worry about losing their jobs if they think they cannot meet work demands or if they do not perform well enough, or if they are perfectionists, he adds. Ms Natasha Mitter, a therapist with Talk Your Heart Out, an online and face-to-face therapy platform, says poor stress-regulation skills or the use of work to avoid personal stressors, such as relationship issues, can also contribute to the difficulty of letting go. The inability to let go could also come with the weighty sense of duty associated with your role at all hours, if, for example, you are a leader or caregiver, she notes. Additionally, ongoing interpersonal tensions, a high workload or a lack of clarity in your job can create a 'lingering cognitive load' even after work hours. Ms Mythili Devi, a counsellor with mental health platform Intellect, notes that the rise of remote and hybrid work makes it even harder to fully switch off as physical cues that once signalled the end of the working day, like leaving the office, have disappeared. 'Cultural or organisational norms may also play a role, where dedication may still be equated with constant availability, subtly encouraging employees to remain responsive after hours,' she says. Ms Mitter says: 'Psychologically, it's hard to let go when work stress becomes internalised – meaning it follows you not because you're being contacted, but because your mind stays in a loop of problem-solving, anticipating or self-criticising. 'For some, the brain starts treating work stress like a perceived threat.' As the feeling sinks in further, it is even harder to relax. Dr Au suggests setting reasonable daily work targets as a good starting point to help dispel that feeling. You can also remind yourself that other than work, you have other roles in your life and you need to engage them as well, he says. Ms Devi says: 'On a personal level, it helps to establish an end-of-working-day ritual that signals to your brain that work is over. 'This could be as simple as tidying your workspace, shutting down your computer or writing down any pending tasks for the next day – a small habit that can help clear your mind and reduce anxiety about unfinished work.' Setting up a dedicated workspace can be helpful for people working from home, she adds. Ms Devi also encourages these workers to physically leave their workplace, even if at home at the end of the day, as something as simple as a short walk can help your brain switch gears from work mode to personal time. 'You can also engage in activities that bring you into the present, such as exercise, creative hobbies or spending time with family.' Ms Mitter says that instead of trying to shut down thoughts about work, it may be better to acknowledge these thoughts and find out what is exactly making you feel this way, before gently redirecting yourself away from them. 'Explore whether part of the difficulty stems from beliefs like, 'I must always be responsible' or 'rest equals laziness'. Challenging these beliefs with evidence or compassion can help.' Jotting down to-dos and concerns at the end of each day in a notebook or a note-taking app can also help the brain feel more at ease, Ms Mitter adds Says Ms Devi: 'It's important to remember that stepping back from work doesn't mean you care less; it means you're giving yourself the time and space to recharge, so that you show up with energy and focus when it matters most.'
