Pleased to meet you! ✌️ 🙂

I am a physicist from the National University of Colombia, where I learned a lot about mathematics and numerical methods. My primary interests lie in programming, particularly in the realm of physical simulations with a focus on sound waves and sound production. I have been extensively exploring the numerical analysis techniques for solving ordinary and partial differential equations, encompassing data creation, pre-processing, post-processing, and visualization. Additionally, I am intrigued by how does sound is produced in animals and objects and the application of machine learning concepts in physics, specially in bioacustics.

Hobbies

I am an adventurous person who loves trying new things and experiences. I particularly enjoy traveling ✈️ and biking 🚲. Recently, I've developed a passion for listening to music 🎧, and I challenge myself to discover at least two new songs every week.

I enjoy living in Bogotá because it is a large city with countless opportunities and cultural events. One of my favorite places is the Cinemateca 🎥, where I have watched incredible and stunning independent movies, each presenting a unique and impactful story. Additionally, Bogotá hosts a wide variety of concerts 🏟️ featuring diverse genres. The city is home to major outdoor events such as Rock al Parque, Salsa al Parque, Hip Hop al Parque, and many others, including jazz, gospel, joropo, and vallenato festivals.

Regarding sports, I am not a big fan, although I do enjoy hiking 🏞️, biking 🚴, and playing soccer tennis ⚽. In the latter, I can be quite a challenging opponent.

Another interesting hobby of mine is my passion for recording sounds 🐦🎙️ of all kinds. The weirder the sound, the more intriguing it is to me. I have developed a particular interest in the sounds of animals, especially birds, frogs, monkeys, and any other creatures that produce unique sounds.

Currently, I am exploring salsa, rock, and jazz music, but I always love discovering new music of any kind and origin. On the left side are some of the music I am listening to now, maybe you will like some of them.

If you have any questions or would like to connect, please do not hesitate to contact me!

Have a great day! 😁

Design, development, and evaluation of a computational physical model to generate synthetic birdsongs from recorded samples

In this study, we introduce a physical-computational model designed to automate the generation of birdsongs from recorded samples. By integrating concepts from numerical analysis, signal processing, and numerical optimization, we formulate the problem as a minimization task to identify optimal parameters that accurately replicate the tempo-spectral features of original birdsongs. Our model undergoes extensive testing and evaluation, primarily focusing on the Rufous-collared Sparrow songs, achieving impressive results with relative errors in fundamental frequency below 2%.

Additionally, we evaluate the model on the Ocellated Tapaculo and Mimus Gilvus species, known for their simpler songs. The results demonstrate the model’s robustness and versatility. To showcase its capabilities, we generate multiple syllables from a single recording, highlighting the model’s potential as a highly effective data augmentation technique for birdsongs. This novel approach addresses the challenge of data scarcity in birdsong analysis, contributing significantly to various fields such as biology, neuroscience, computer science, and ecology.
