"Two years ago I started my PhD in the Physics department. From labs to field, I play around with the mass spectrometers in order to measure what is in the air. You know, this specific smell that you get in the forests is coming from a molecule called alpha-pinene. When emitted from the trees, this molecule gets oxidized and produces other molecules that are found to play a role in the formation of new particles in the atmosphere. We had no clue about this just 10 years ago! So after all, through physics and chemistry, it becomes all about climate! In few weeks I will leave to the Antarctica peninsula to see what triggers the formation of new particles in this very pristine region of the globe. I am quite excited for this new scientific adventure and I crave to put my feet on this continent! Wish me luck!"
