Maria Eugenia Pirera

Argentina

My name is María Eugenia Pirera I was born in the city of Miramar, state of Buenos Aires, Argentine Republic. I studied Dentistry at the National University of La Plata and continued my specialty in maxillofacial surgery at the Pontificia Universidad Católica Argentina. In 2018 I did an AOCMF fellowship at the Universitatpital Basel where I discovered my passion for research to find therapeutic alternatives for patients. In 2020 I obtained a scholarship at Harvard University for the program of Global clinical Scholars Research Training where I expanded my knowledge in the field of research. I am currently starting as a Research Fellow Regenerative Orthopedics for a period of 1 year. I am very grateful to join the team and have the opportunity to gain experience in the field of tissue engineering research. I appreciate the varied cultural and interdisciplinary experience as I work at the AO Center and look forward to establishing long-lasting collaborators, friends, and mentors for my career.

André de Souza Salvatore

Brazil

São Paulo State University
(UNESP – Botucatu Campus)

I am from São Paulo, Brazil. I finished my studies in veterinary medicine in December 2018 at the São Paulo State University (UNESP). During my veterinary program I had a special interest in Equine surgical and orthopedic approaches as well as a passion for research and the role of research into developing new diagnostic methods and treatments. Led by this passion, I sought to assist in a research project designed to investigate biomarkers for colic syndrome. After my graduation, I completed a one-year Internship at the Clinic for Horses at the Tierärztliche Hochschule Hannover (TiHo). This experience was ideal for me to understand the complexity of each orthopedic case, as well as how the osteosynthesis technique must adapt to address and treat each case differently. By joining AO, I hope that by managing and assisting in a variety of animal projects, I will be able to better understand the science behind the complexity of osteosynthesis. In addition, I hope to use one of these projects as my dissertation for a doctorate degree. Furthermore, I hope to develop my surgical expertise, as well as my critical thinking. My final goal is to apply for an equine surgical residency in Europe, and I'm sure that I will be able to use the experience gained here in my future veterinarian career as an equine orthopedic surgeon. I hope to bring the AO methods and philosophy to my home country of Brazil, and assisting with other colleagues around the world ultimately contributing to bring a better understanding and outcome for equine orthopedic emergencies.
