My passion for plankton began when I was just ten years old. It all changed for me on December 31st when I received a simple plastic microscope as a birthday present from my parents. I can still vividly recall observing my first protists--it remains one of my most enduring memories. The sample came from a flower jar on our dining table, where I noticed tiny dots moving around on the water’s surface. Placing a drop of that water on a glass slide and looking through the microscope, I was astonished by the new world that unfolded before me. Creatures like Euglena viridis (a flagellated microalgae) and Stylonichia mytilus (a flat ciliate) dominated the scene. From that moment on, I could not resist exploring every pond, vessel, river, or lake I came across. I used to carry small containers in my pockets (and still do) to collect water samples for later observation.

My interest extended beyond plankton to other forms of life, leading me to study Biology at the University of Barcelona, my hometown. There, I had the privilege of learning from inspiring educators who fueled my drive to pursue this career. Although working as a bartender, cook, and waiter on weekends and summers slowed down my studies, I eventually completed my degree and began my PhD at the Marine Sciences Institute (CSIC, Barcelona). I shifted my focus to marine zooplankton, primarily copepods, despite never having been particularly drawn to marine systems (probably due to my tendency to get seasick!). Yes, even marine biologists can struggle with seasickness. After four years of dedication, I successfully defended my PhD.

The next step in my journey was a postdoctoral position at the University of Hawaii, USA. I am not going to lie--I worked hard, but I also had an incredible experience. It was in Hawaii that I first became interested in marine microzooplankton, which has captivated me ever since, although I have not lost my enthusiasm for larger zooplankton.

Following my postdoc, I returned to Barcelona, spending a few years hopping from contract to contract before securing a permanent research position at the institution where I completed my PhD. Now, after more than three decades devoted to the study of plankton, I am passionate about sharing my knowledge with all kinds of audiences, especially the next generation of scientists. This is what motivated me to write this book, offering a practical and accessible guide to the fascinating world of plankton. I hope you enjoy it.
