Biomedical Informatics (based in China) BSc (Hons) personal statement example

Why do you want to study this course or subject?

At the optician's where I have worked for seven years, my first job with most patients is the pre-test. This means an autorefractor reading, a puff of air to measure eye pressure and a photograph of the retina. Each machine prints its own numbers, and the optometrist reads them alongside the patient's history to decide what happens next. I became curious about the step in between, where measurements from separate devices become one record a clinician can trust. When our practice changed its records system, I spent weeks checking that recall dates and prescriptions had transferred correctly. Small inconsistencies, such as a date entered in the wrong format, could quietly stop a patient being invited back. Biomedical informatics appeals to me because it sits exactly at that point: biology and medicine supply the questions, while computing and statistics decide whether the answers are reliable. I want to learn the underlying science properly, rather than only the software I happened to use at work. Studying in China also attracts me. I have been learning Mandarin at an evening class for two years, and I would value training in an international setting where questions about health data arise at a very large scale.

How have your qualifications and studies helped you to prepare?

I left school after A levels and have returned to study through an Access to HE Diploma in Science, which I am completing part-time alongside work. Modules in biology, chemistry and mathematics have rebuilt foundations I had let slip. I especially enjoyed cell biology, where learning how DNA is transcribed and translated finally explained terms I had heard at work but never understood. In mathematics I have covered differentiation, logarithms and basic statistics, and I now check my working far more carefully than I did at seventeen. For my research unit I wrote about diabetic retinopathy screening. I compared how trained graders assess retinal photographs with how automated grading tools are evaluated. Reading published guidance showed me that a tool's usefulness depends on its sensitivity, its specificity and the population it was tested on, not just on a headline accuracy figure. Alongside the diploma I completed a free online introduction to Python. I used it to write a short script that tidies a spreadsheet of harvest weights from my allotment and plots them by month. It is modest, but working through error messages taught me patience and gave me a feel for how code and data interact. I have also read Siddhartha Mukherjee's The Gene, which helped me place modern genomics in its history.

What else have you done to prepare outside of education, and why are these experiences useful?

My job has given me daily contact with patients of every age, many of them anxious about their sight. Explaining a retinal photograph to an elderly customer, or reassuring a child before the air-puff test, taught me to translate technical information into plain language without talking down to anyone. I also became the person colleagues asked about the booking software. I wrote a one-page guide for new starters on recording recalls consistently, and the manager now gives it to everyone on their first day. That small piece of work showed me that good data often depends on clear habits as much as on clever systems. Outside work I sing tenor in a community choir and help keep its membership spreadsheet up to date. I also share an allotment plot with my neighbour, which involves a surprising amount of planning around the weather and our watering rota. Learning Mandarin has been humbling. Progress with tones and characters is slow, but regular practice and a willingness to sound wrong in class have brought me to a basic conversational level, and I am working towards the HSK 3 exam. Returning to education in my late twenties has meant organising study around shifts, and I have found that I work steadily and independently. I am ready to commit fully to a demanding degree that brings together the science, computing and people I have come to care about.
