Research

During my research career, my primary focus has been on investigating the effects of exercise and physical activity on cardiac autonomic modulation in two specific populations: athletes and older individuals. This line of inquiry has allowed me to delve into the intricate relationship between exercise and cardiac autonomic modulation, while also exploring the influence of various variables to develop a comprehensive understanding.

In addition to my core research, I have actively pursued collaborative opportunities beyond my primary domain. Leveraging my expertise in applied statistics and Bayesian data analysis, I have contributed valuable insights to these collaborative efforts. This multidisciplinary approach has broadened my research horizons and facilitated the exchange of knowledge across different fields.

In the following section, I provide a concise summary of my research undertakings since 2021. These endeavors have not only shaped my expertise but have also made significant contributions to the advancement of knowledge in my field.

Software & Web design

Over the years I have encountered multiple challenges, both academic and personal. In these contexts, being able to use the tools that a digitalized world offers us is vital to be able to adapt in a world that evolves in a complex and dynamic way every second. In this way, and in a self-taught way, I have cultivated technological and computer skills in response to these challenges. Below, I show the projects I have developed, both in terms of web design and intermediate products of published research projects that I have led and collaborated.
