Trophy Winner 2024: Caleb Tang's Oliphant Journey

What inspired your winning Oliphant Science Awards project?

During year 11 I was fortunate enough to complete a work experience placement at a pathology lab, Clinpath, and this included their microbiology department. Bacteria and microbiology were areas that we had received very little exposure to throughout school and in the science curriculum, but always something that I was quite fascinated by – how these essentially invisible, yet at the same time seemingly omnipresent blobs of an organism are so crucial to the ways our bodies and the environment around us function, and how they may also contribute to dysfunction.

This was my first introduction into the world of microbiology, and so at the start of year 12 when I was given the opportunity to write a research paper on a topic of my choice as part of my extended essay for my IB diploma, I knew I wanted to involve bacteria in some way. Many of the bacteria that I was interested in investigating were pathogenic and therefore deemed ‘unsafe’ to experiment on in the school laboratory (understandably so), but one night while researching the pathogenesis of acne, a condition I had struggled with at the time, I stumbled across a newly published paper discussing recent findings on the role of a non-pathogenic bacteria Staphylococcus epidermidis in regulating levels of the pathogenic acne-causing bacteria Cutibacterium acnes.

This fascinating interaction between the two bacteria laid the foundations for my project. My exploring of the effects of different coloured light treatments was inspired by the increasing popularity of LED face masks for cosmetic acne treatment that I had observed at the time, and all the different colours and wavelengths of light that they used. This was underpinned by the fact that very little was known at the time about how different coloured light treatments actually impacted population size of Staphylococcus epidermidis, or the exact mechanisms behind how light may inactivate Staphylococcus epidermidis, which is what I set out to explore.

What impact did participating in the Oliphant Science Awards have on you at school and beyond?

I think above all else, participating in the Oliphant Science Awards each year encouraged me to challenge myself in new and different ways, and expand beyond what I was exposed to through the school curriculum. Even from the beginning of my journey with the Oliphant Science Awards, having a long-term project to work on and chip away at in the background of my busy school life taught me very many valuable lessons in time-management and self-discipline.

Learning to balance my Oliphant Science projects alongside schoolwork, footy, chess, piano, and everything else I had going on at the time helped me build a really strong work ethic and desire to learn quite early on, as well as teaching me to find enjoyment in not just admiring a completed project, but also reflecting on the process, and overcoming all the challenges, big or small, that come up along the way.

These skills continued to benefit me throughout school as my workload continued to get bigger and bigger each year, yet I still strived to attempt to submit a bigger and better project into the Oliphant Science Awards each year. Even beyond school now, I think having that continued desire to keep learning and keep busy, which originated from engaging in extracurricular pursuits such as the Oliphant Science Awards, continues to fill my life with so much to look forward to each day, and keeps me curious and motivated to seek out new challenges.

Did the Awards influence your passion for science or your study/career direction?

Definitely. Growing up, science was certainly not one of my favourite subjects at school. Nor my second favourite. Nor my third. But through engaging in the Oliphant Science Awards, I was really exposed to a whole new perspective of science, not just as a subject at school, but as an ever-evolving field, with seemingly infinite possibilities. Participating in the Oliphant Science Awards provided me with a very hands-on approach to learning, and provided me with an avenue and rare opportunity outside of school to use theoretical knowledge to inform practical undertakings in a topic of my own personal interest.

This helped me realise that this is something that I want out of my career as well; something practical and hands on, where I can see the positive impacts of my work come to life in real time, and also something that would challenge me, keep me thinking, and keep me wanting to learn more, whilst being able to do good for the world. I am currently pursuing a degree in medicine, and so far, it has ticked all of those boxes for me.

Do you have a favourite memory or story from your Oliphant journey that you’d love to share?

Maybe not my favourite memory, but definitely a memorable one, was in year 7 in the waiting room just before my interview for my computer programming and robotics submission, I realised that one part of my smart garbage truck project, the actual arm mechanism for grabbing and tipping the bins, had suddenly out of nowhere stopped working, despite operating flawlessly all morning at home and the night before. In that waiting room, I vividly remember scrambling to try to get the issue fixed, checking all my wiring, the batteries, reuploading the code and inspecting all the sensors, but just nothing could get it to work.

And so when I was called up to the judging room, I had no choice but to explain to the judges that this feature of my project had stopped working for some reason, and confess that I didn’t actually know why. I felt so disappointed in myself coming home that day, sipping sadly on my sugar cane drink that my mum had bought from the Central Markets in hopes of cheering me up, and thinking that all of my work had gone to waste.

And then as soon as I got home and tested out my project again, it worked faultlessly again as if nothing had ever happened. To this day, I still have no idea why the arm mechanism just stopped working, but it did teach me that not everything will always go my way, as well as the importance of being prepared for all sorts of unexpected situations to arise – I certainly made sure in future years to record video footage of my projects working beforehand to show the judges just in case something like this happened again, although it never did.

My entry was a SHE task for my Year 12 Biology course. In writing the paper, I was inspired by the potential of a novel and innovative therapy such as CAR T-cell therapy, that seemed to have the potential to produce such a large impact on patients, with a reduction...
