This post is part of a series profiling the top 22 Best of Category award winners of the Intel International Science and Engineering Fair (ISEF) 2019. Intel ISEF is the largest pre-college, international STEM competition in the world. This year’s competition included participants from 80 countries, regions and territories. Every year, the brightest young scientists from all over the world come together to participate in this incredible fair.
In this year’s competition, one of the top winners in the category of chemistry, Helena Jiang of Gainesville, Florida, developed sensors that could plausibly detect various pollutants in the environment by changing colors. Helena’s new sensors aim to be affordable and user friendly. They can potentially improve the environment by detecting even trace amounts of toxic material in liquids as well as solid objects.
Here is a conversation we were able to have with Helena.
What was your experience like at Intel ISEF?
The experience was definitely once-in-a-lifetime. Every single aspect was mind-boggling— from the camera swooping down during the awards ceremony to just standing next to and talking to someone who lives a completely different life from you. Someone can be from another U.S. state or from an entirely different country, yet we both have the same interest in science. There is nothing in the world I would trade for it.
What's the biggest lesson you've learned thus far in your scientific career?
Be present, and question things that may seem negligible, yet stick out to you. There was a point in my project where the spacer I had used to create my sensors actually started becoming detected by the sensors themselves. The spacer was only used to separate glass slides, but it caught my eye and I questioned it. My peers originally thought it might've just been contamination, but I firmly believed it wasn't.
How do you deal with setbacks?
Much like Feng Zhang, I too think it is important to take a step back and look at the whole. I like to do this every once in a while, especially during a setback. Sometimes we become so focused on one specific aspect of a research project that we block out the others. An easier solution may lie outside of the box we're currently focused on.
What do you feel is the most important invention/scientific breakthrough in the world?
So many things can be said for this answer. Without the discovery of the lightbulb, the wheel or penicillin, our modern world would not be the way it is today. However, though this may sound silly, I believe the most important scientific breakthrough is the discovery of the chocolate chip cookie. In the 3rd grade, I learned that chocolate chip cookies were actually made on accident. This opened my eyes, and my way of thinking was changed afterwards. Failure is one of the most important obstacles on the road to success.
How do you unwind when you're not doing research?
When I was younger, I danced competitively. I love just dancing around in my room, listening to music or even just spinning down supermarket aisles. Though I don't do this enough, I also love taking a good run around my neighborhood, maybe even doing a little dance move in the middle!
As a child, Brian Wu (ISEF 2018-2019), a senior at Horace Mann School in New York City, was fascinated by the stars.
