• 💙 My main interests are Machine Learning, Natural Language Processing, Language Models and ML-based Software Development. I also really enjoy teaching!
• 🏫 I hold a master's degree in computer science from the University of Chile which was gratefully supervised by Felipe Bravo-Márquez.
• 🏛️ I currently lead the technology transfer area at IDIA, an initiative that brings together the main FCFM departments (DIE, DII, DCC, DIM) to articulate research, technology transfer, teaching, and project capabilities at Universidad de Chile.
• 🧑‍🎓 I'm alumni of the RELELA (Representations for Learning and Language ) research group of the University of Chile.
• 🌟 I was the main developer of WEFE: The Word Embeddings Fairness Evaluation Framework, an open source library for measuring and mitigating bias in word embedding models. 2 papers published and 182 GitHub stars.
• 📹 I have been several times part-time lecturer at the University of Chile. For the MDS7202 Scientific Programming Lab for Data Science material, check out the videos at the following youtube list and the course material here.
• 🥕 I really enjoy cooking and outdoor sports such as cycling or hiking.
• 📸 I also like photography, but I still have a lot to learn!
