Summer Internship at EPFL

My summer at EPFL was perhaps one of the best summers I have ever had! If you wonder why, here is a bit of my story:

At EPFL, I worked in the Laboratory of Renewable Energy Science and Engineering (LRESE) and I worked there from July to September 2015. My project was about maximizing the performance of water splitting device, using sunlight as the energy source to form H2 and O2 as the valuable products. This technology has a very bright future in the next few years, and I am proud to be part of its development.

During my internship, I learnt so many things, both in academics and socially. From the academic point of view, I learnt how to structure my approach in doing the project. I learnt how to manage my daily timetable and split the tasks wisely so that I could finish the project in a very limited amount of time — I learnt how to multitask. I had the chance to use some sophisticated laboratory equipment such as Scanning Electron Micrograph (SEM) and Metal Sputtering Machine – to use these machines I had to enter a chamber called cleanroom and wore an “astronaut-like” outfit! But more importantly, I learnt that in research, 75% of your time is spent trying to explain something that you did not expect to happen in the first place! Apparently, that’s what science is about.  This experience will surely help me succeed my 4th year project in Oxford which I am currently doing – the internship seems like a head-start!

For my social life, I have also gained a very unforgettable experience. I had the chance to meet and be friends with brilliant students coming from top universities around the world – MIT, Cambridge, Stanford, you name it! Building a network and friendship with these people is surely something that is priceless. We had several trips together, once was to CERN, Geneva. The largest scientific lab on earth, a place that is second to none!

In overall, I would undoubtedly recommend this programme to anyone who wants to have a great AND productive summer. Not only those who have passion in research, but also those who are considering it. You won’t waste your time being here. The FUN part is guaranteed!
