How does flat cloth warp flawlessly around a 3D human body? I always admired how my mom and other tailors crafted perfect fits from just three measurements. The secret lies in developable surfaces, which bend without stretching. While knits stretch via loops, woven fabrics deform by altering the angles between warp and weft threads. This is the essence of Chebyshev nets, a geometric framework modeling fabric as a network of inextensible fibers. By linking geometry to garment design, clothing becomes a living mesh of code where math conforms to the human form.
My very first sewing calculation lessons
If I immerse myself in constructing my own graph in geometry, I could predict how likely I would bump into my old Vietnamese friend on a Saturday morning in Singapore in Game Theory, the science of decision-making. What fascinates me most is how optimal yet paradoxical strategies often challenge ordinary intuition: sometimes we practise more of something precisely to avoid ever needing to use it, or cooperate only because competition exists. Game theory grounds chaos into order, revealing that nature's strategic rationality often challenges human intuition.
While pure math offers flawless order, I fell in love with statistics for the imperfections it reveals. It turns dry data, noise, and anomalies into structured insight. Transitioning to R allowed me to decode decades of survival trends through graphical visualization, transforming chaotic uncertainty into sharp, future-informing predictions with simple commands.
Statistics embeds theoretical math into code, untangling massive datasets. I once thought coding was just binary (reminiscent of a sweet binary love confession I once received) but computers are beautifully multilingual. I found joy designing website elements in JavaScript, then advanced to Python for machine learning. Because no model is flawless, my favorite challenge is experimenting with high-variance simulations to reduce algorithmic bias and crack the black box.

Math, to me, is a universal language and the backbone of all sciences. First exposed to its wonders at the age of four in Vietnam, I fell in love with a subject that manifests in diverse forms and cultural philosophies. In Vietnam, I would instinctively deploy Vieta's formulas to solve quadratic equations; in Singapore, I find myself completing the square. Where Vietnamese math challenges me to prove a multivariable inequality through pure algebra, Singaporean math prompts me to sketch it visually. Yet, both approaches share an underlying creative beauty. This creativity shines whether I am constructing auxiliary lines to unlock a geometry problem in Vietnam, such as my favorite, the Butterfly Theorem, or visualizing 3D spheres to conquer vector questions in Singapore.

Through mathematics, I have been privileged to glimpse the beauty of infinity hidden within geometric progressions and fractals. I see the very architecture of Singapore mapped out through differentiation and vectors. Ultimately, math has given me a unique lens to appreciate how different civilizations speak the exact same truth in their own distinct tongues.
Some of my favorite and prettiest math manifestations
1. The Esplanade - Theatres on the Bay
Ever heard of a triangle with more than 180 degrees? That is exactly why I find the Esplanade, Singapore's Durian, absolutely brilliant because it turns raw calculus into an architectural icon. By using non-Euclidean geometry to map those impossible triangles onto complex 3D curves, and vector math to tilt 7,124 spikes against Singapore's equator sun, it pushes digital algorithms to their absolute limits.
2. The Tower of Hanoi
Ever thought a children's game could blueprint a fractal? The Tower of Hanoi turns raw recursive constraints into a geometric masterpiece. By mapping coordinate sequences across an exponential landscape of 2^N-1 steps, its entire state space crystallises organically into a flawless Sierpiński triangle.
3. Fibonacci sequence
Ever imagined a simple addition rule blueprinting the entire universe? The Fibonacci sequence turns raw arithmetic summation into nature's ultimate geometric signature. By compounding a basic recurrence relation where each step absorbs its past, it forces shifting numerical ratios to converge flawlessly onto the Golden Ratio, curling linear integers into a universal spiral that maps everything from a human fingerprint to the architecture of swirling galaxies.
4. Euler's Formula
Five sovereign constants from entirely separate mathematical dimensions colliding to form a single, perfect sentence. By steering e's engine of continuous growth into the imaginary realm of i, linear acceleration twists into a circular rhythm that rotates exactly pi radians across the complex plane, pulling unity back to the absolute balance of zero.

To me, the heart is a sacred organ, the only one that continues beating until we draw our last breath. Yet, ischemic heart disease was the top global cause of death in 2025. Have you ever wondered how old your heart is?
This research trains smartwatches to analyze microscopic pulse-wave geometry. The key finding is that male and female arteries age along completely separate physiological tracks. By building a multi-level Stacking Ensemble framework (XGBoost, RF, SVR) and blinding it to chronological age to prevent data "cheating", our accuracy skyrocketed, slashing male prediction errors significantly. Among 15 multidimensional variables, my team identified Pulse Pressure (PP) as the dominant mechanical aging trajectory in men, while identifying Mean Arterial Pressure (MAP) as the key indicator of micro-vascular elasticity shifts in women.
Through the process of learning to deploy AI, I discovered that monolithic models fail against real-world biological noise. I learned to stack diverse architectures so they actively correct each other's weaknesses. Moving forward, I aim to integrate hormonal biomarkers to optimize the female cohort variance and transition this 46ms, 7.7MB framework into clinical trials. Ultimately, I hope to relieve the burden of at-risk groups via uncovering hidden arterial aging long before traditional cardiovascular symptoms strike.

While high-profile oncology or vaccine development dominates global funding, maternal health remains a critically overlooked public health frontier, severely threatened by declining humanitarian aid. This global austerity directly undermines United Nations Sustainable Development Goal Target 3.1, which aims to reduce maternal mortality below 70 deaths per 100,000 live births.
Imagine a pregnant woman in the middle of winter just beginning labor, weakened by anemia and malnutrition. The nearest clinic is over an hour away, across steep mountain paths. This devastating reality of mothers in Lesotho, a landlocked country in South Africa with the world's highest maternal mortality rate, inspired me to investigate the 20-year trajectory of antenatal care (ANC) utilisation from 2004 to 2024. While I am heartened to see basic access to ANC expanded, severe socioeconomic inequalities emerged at the intensive, WHO-recommended eight-visit model, where high national averages frequently mask deep underlying injustices against impoverished households.
Visualising these stratified demographic data through R, I took pride in making mothers' lives in another country a little safer by proposing targeted policy shifts. Healthcare policies must pivot from passive coverage targets toward proactive, community-linked tracking models like maternal waiting homes and automated digital referrals. Ultimately, I hope to use Lesotho’s current health reforms as a launchpad to translate life-saving care continuity to vulnerable, developing communities worldwide.
Image-recognition risk-warning multimodal system for scoliosis
- Co-researcher and developer
- Presented at the 2026 NUS – SYNAPXE – IMDA AI Innovation Challenge
AI Spine Diagnosis Prototype
Remember your last school screening for scoliosis? I don't. Healthcare systems handle this through a rigid, fleeting window, checking kids for a brief moment in youth before completely dropping the ball. This short-term approach leaves sedentary adults entirely vulnerable, blind to the silent, asymptomatic curves progressing behind their desks until they are forced into expensive, invasive surgeries.
This systemic gap sparked my team to design a lifelong spinal monitoring companion. Coding this software completely rewired my perspective on medical technology; I realized life-saving AI doesn't belong locked away in elite, clinic-bound hospital hardware. By training a computer vision model to map subtle shoulder, hip, and trunk symmetries from a simple smartphone photo, we turned raw, everyday pixels into instant clinical radar. We paired this with an empathetic AI chatbot to bridge the long-term care void, providing 24/7 condition management guidance.
Our dream is to fuse these features into a dynamic, multimodal AI that tracks live postural habits. We want to put the power of prevention directly back into people's hands: catching silent structural shifts at home long before they can rewrite a person's physical future.

DyspneaCare Asthma-Monitoring Prototype
Designer and Developer
Every puff of my bronchodilator is a reminder that breathing should not be a luxury. In Vietnam, pediatric asthma rates are three times the global average, a stark statistic driven by the harsh realities of climate change and industrial pollution. This forms a heartbreaking generational inequality, where future generations pay for modern comforts with their health.
Driven by my own diagnosis, I sought a proactive solution by engineering an IoT, smartwatch-integrated asthma monitoring system. To map the complex interplay between environmental triggers and physiological responses, I used Onshape to 3D-print hardware houses that sync internal biometrics (MAX30100 for heart rate, MAX30205 for body temperature via ESP32-C3) with external pollutants (MQ-135 for NOx/NH3, ZH03B for fine particulate matter, and AHT20 for humidity). Coding in C/C++ for low-level hardware optimization, I built a web application using HTML/CSS and DOM manipulation to map patient data, offer medical advice, and alert nearby clinics during emergencies.
Testing the prototype on my parents, my very first patients, deepened my vision. If given unlimited resources, I would expand this technology globally, establish a philanthropic fund to distribute bronchodilators to low-income families, and pioneer CNN and Vision Transformer models for advanced lung X-ray diagnostic mapping.
Droptest on my parents
Care Community Services Society Singapore
Volunteer and programme designer
Being the youngest one in the house, I often wonder why I learn better with my friends than when asking my sisters. Math is a domain where I inherit from my parents and unbeatable among the three. Growing up in Vietnam, visual logic math sparked my lifelong love for the subject. I fancy the idea of luring someone in this realm like I was lured into.
The Saturdays volunteering at Canberra have been one of the most exciting ones I look forward to my menteers, children from less fortunate backgrounds in Singapore. I recalled my first session. I was trembling on hearing of my role as coaching math to PSLE students, a Singapore's secondary school entrance exam, as I did not take PSLE myself and now teaching math not in my mother tongue. But I learned that willing to give and guide someone ultimately outpaces the need for accuracy or preparation. Much as I was hoping to instill stoicism and perseverance in the kids, I made her cry on the fifth attempt. My rigid method taught me that good intentions are not enough; understanding a child's unique mindset is crucial. Probably why my sisters had a hard time also!
Seeing the repeating math games that the children can play, my team proposed creating new ones for P4,5,6. But it gave me a harder time than doing olympiad questions as I must consider the receptivity of primary school students.
Ultimately, these math games transformed dry academic concepts into an exciting, collaborative experience. I have achieved what I intended too: luring the kids into the love of math. And what I always remind my mentee is drawing the asymptote and saying how math joy is infinite. Teenagers like me also enjoy being a kid!
My Third Space
Creator
Game theory felt so real in both nature and geopolitics to me. Eager to cross-pollinate these insights, I used my role as Hwa Chong Economics Moderator to launch an interdisciplinary multimedia series, a "third space" where economics, math, law, and biology collide. Here are two episodes I am most proud of:
The Economics of Evolution: I broke down the mathematical optimization of marginalist ant colonies, symbiotic externalities, and free-riding bacteria in a classic Prisoner's Dilemma.

·NUS Saw Swee Hock School of Public HealthWith the 3M+S healthcare scheme, Singapore boasts one of the most robust healthcare systems in the world. Singapore's rapid COVID-19 vaccination is a testament to this. I thought so too until I interned with Professor Alex Cook, the Vice Dean of the Saw Swee Hock Graduate School of Public Health, and saw the critical systems underbelly - the migrant workers dormitory isolation and suicide crises.
Professor Alex Cook is a veteran in infectious disease modelling and statistics, including dengue, COVID-19, influenza and other respiratory pathogens. My determination to intern with him at the Graduate school was predominantly because of his renowned Mathematical Disease Modelling Programme across South East Asia countries and his wealth of long-term understanding and knowledge about the regions that I live in and are passionate about.
One of my favourite moments was when we laughed over the classic statistician joke: "How do you tell the difference between an introverted statistician and an extroverted statistician?"
"The introvert looks at his own shoes when talking to you. The extrovert looks at yours."
"But both love being completely significant." - I replied.
It was a small joke, but one that captured something I admire: behind every model, every dataset and every confidence interval are people quietly working to improve lives, often without seeking the spotlight.
I'm equally grateful to Professor Teo Yik Ying, the Dean, whose outward-looking leadership has inspired countless young people, including myself, to believe that students can help shape the future of health, not just inherit it.
My diary...
1. Retreat with Health Intervention and Technology Assessment Program Foundation (HITAP)
Shadowing at the cross-border HITAP (Thailand) x SSHSPH (Singapore) consortium revealed that regional public health relies on simulating reality to correct structural injustices. Reviewing Thailand's Maternal Pertussis Immunization program and the HPVADVISE Model showed me how abstract statistical tools like Markov models serve as mathematical engines for health equity. As the youngest in the room, motivated by hearing all these impactful, ground-up projects, I stepped up to bring my own data and field experiences to our ASEAN table. I contributed my insights on migrant healthcare worker screening, maternal health systems, and the statistical tracking of rare diseases in Vietnam.
2. Exchange with the UCL Global Business School for Health Faculty of Population Health Sciences
Global health requires an intergovernmental perspective. Meeting graduates at UCL allowed me to view Singapore's safety net through a different lens, realizing systems like Medifund often react to inequalities rather than preventing them. True health system architects cannot rely on isolated, short-term pilots; they must scale immediately to prevent structural failure.
3. Hosting Dr Mohamed Javid - the International President of Doctors Beyond Border
With his depth of experiences in bringing care to regions in crises, he offers a critical and practical lens to the challenges by these Doctors Beyond Border: the unwillingness of states to let foreign doctors in despite their benevolence. Hearing him speak on medical neutrality in war-stricken zones under International Humanitarian Law bridged the gap between global diplomacy and local execution.
4. Analyse research paper
Being entrusted with putting this research into layman terms by Dr. Alex, I discovered how Thailand's Universal Coverage Scheme (covering 75.7% of the population via the UCS) demonstrated remarkable resilience. This evaluation tied directly back to my HITAP meeting, where I saw the intellectual architects of this very system in action. The data revealed a sharp inverse relationship between bed capacity and net hospital financial reserves, exposing significant asymmetric shocks across providers. Top-down funding proved ineffective without provider-level agility.
5. Collab with National Centre for Infectious Disease to build robust models for the next outbreak in Singapore
I learned how statisticians utilize data features like line listings, prior/posterior probabilities, the effective reproduction number, and Pearson correlation matrices to map linear relationships across complex datasets. In a crisis, the line between research and policy dissolves!
