Upwork | Jun 2023 - Dec 2023

Data Scientist Freelancer

⚬ Developed a user-customizable content-based music recommendation system based on song features from the Spotify API and an NLP framework to include lyrics’ sentiment analysis. k-means algorithm and enabled recommendation of similar songs with 90% song match from user-generated playlist data. ⚬ Processed, cleaned and extracted insights from food poisoning claim data from a Brazilian food company that uncovered location-based patterns of malpractice with greater than normal processing times of the food claims.

University of Washington | Jun 2020 - May 2023

Postdoctoral Researcher

⚬ Contributed to the development of a ML Reinforcement Learning model based on a DDPG Actor-Critic neural network infrastructure to design optimal nano-materials and extend its usage to include polymers. ⚬ Developed pipelines to automate the web-scraping and analysis of chemical computational data, speeding up processing times by approximately 40%.

Washington State University | Jan 2016 - Jun 2020

Research And Teaching Assistant

⚬ Designed and applied computational methodologies embedded in Python code to investigate chemical phenomena, resulting in 5 articles as lead computational contributor. ⚬ Transferred and tested the applicability of the graph theory algorithm PageRank, developed by Google, to study molecular structural transformations uncovering new correlations between graphs and spectroscopy. ⚬ Lead the computational chemistry research of a DOE research project (IDREAM) to understand the solvation dynamics and structure of the radioactive waste stored at the Hanford Site resulting in 6 publications.

University of Havana | Jul 2013 - Dec 2015

Junior Instructor

⚬ Design and lead the lecturing of entire courses of advanced chemistry and mathematics subjects for undergraduate and graduate students including Thermodynamics, Quantum Chemistry, Nuclear Chemistry, Mathematical Analysis and Statistics and Probability.

Institut de Physique Nucléaire Orsay | Université Paris-Saclay | Mar 2015 - Jun 2015

Research Intern

⚬ Performed research employing Density Functional Theory to understand the binding mechanism of actinide oxide complexes and the active sites of the calmodulin protein leading to a published peer-reviewed article.
