It is just a small part of the scientific evolution
My passion for science was ingrained in me from a young age. As a child, I loved playing with mechanical tools and had a habit of disassembling things to explore their inner workings. Thanks to the open-mindedness of my parents, I was encouraged to pursue my interest in science.
During my undergraduate and graduate studies, I chose to specialize in photonic engineering at National Cheng Kung University in Taiwan, a country in the far east. It was there that I got my first glimpse into the fascinating world of lasers and optical spectroscopy. These experiences fueled my desire to expand my knowledge and engage in research activities as a PhD student.
Currently, I am working as a PhD student at the Istituto Italiano di Tecnologia in Milano, under the guidance of Dr. Annamaria Petrozza. Our research primarily focuses on the photo-physics of Perovskite materials. We employ various ultra-fast time resolved spectroscopy techniques; these techniques work like an ultra-fast camera which allows us to monitor how the excited carriers act. Most of the optical systems in our laboratory are built by our PhD and post-doc researchers; this is also one of my favorite parts of the work, because I can learn the fundamental technique behind the experiment, and further expertise the facilities.
My project specifically revolves around the photo-physics of Perovskite lasers. We utilize Perovskite as the gain material and investigate the underlying mechanisms behind its stimulated emission properties. This research field has the potential to greatly impact the future development of miniature laser devices. The research works we’ve been doing sometimes is just a small part of the scientific evolution, the efforts we’ve made may not pay in cash instantly, the thought that motivate me on the path is that maybe our research may play as an important role in the future technology and change the world one day.
