Life is a constant problem-based learning experience: learning how to drive; how to use a smart phone; how to raise your kids… These are simple examples of constant challenges to our learning abilities. Veterinary education is also a great challenge, especially in the 21st century. Making learning an engaging and unique experience in the context of our current society is what inspires and motivates me. My enthusiasm is fed and nurtured by the excitement, passion, and extreme dedication of my students. My joy is to see students reaching a truly “Aha!” moment by discovering and combining different pieces of information when I guide them. As a life-long learner, my goal is to expand veterinary education by exploring and merging established and new didactic techniques. Veterinary medicine is a natural PBL experience, where there are no two equal cases. Good veterinarians are defined by their ability to make multiple connections between areas of knowledge, to provide optimal patient care, to have great communicating skills, and to be life-long learners. The skills provided by student-centered learning combine these desired abilities in harmony. Since I joined the WU-CVM I have witnessed the blossom of not only great veterinarians, but also great thinkers and citizens. I strive to participate in this collaborative effort as my contribution to the society and to future generations.
