Personal Profile

Hi there, welcome to my homepage! I built this webpage to post my activity, records, and other interesting events that happen in my life and I don't want to forget.

In a few words, I am Lluís, a student of ETHZ in the Data Science master's and now I am doing the Master's thesis at Sony. I consider myself a problem-solver and want to use my skills for a better future for my family and friends.

Work Experience

September 2023 - March 2024

Sony
Master's Thesis Student

Sony | Stuttgart Laboratory 1, Stuttgart, Germany

Master's thesis on Multi-Objective Optimization GFlowNets.

Collaboration with the Deep Generative Models lab of Sony, Tokio, in the proof of bounds of Consistency Trajectory Models loss. Keywords: GenerativeAI, Reinforcement Learning, MCMC methods

January 2023 - August 2023

Akina AG
Junior Data Scientist

Akina AG | Zürich, Switzerland

Worked on transformer-based models for online action-recognition and motion analysis models.

Keywords: Transformer, Computer Vision, Privacy-Preserving models.

September 2022 - January 2023

kaiko
Data Scientist Working Student

Kaiko AI | Zürich, Switzerland

Helped the company Kaiko AI in the course Data Science Lab

• Worked on tissue classification for cancer detection, achieved comparable results to SOTA methods
• Digged in Survival analysis and image segmentation

March 2022 - September 2022

Hilti
Data Scientist Intern

Hilti | Schaan, Liechtenstein

Different Data Science and ML projects.

• Designed and created an ML pipeline in Python from the ground up: data preprocessing, feature engineering, and model selection to and the best geometrical and physical parameters of a new generation of drill-bits in order to optimize their performance
• Researched and implemented the Bayesian Additive Regression Trees model to improve previous models for a crucial dataset of the company, leading to a similar level of accuracy but providing a measure of model uncertainty. Presented the results to the Technical DS Exchange & Community, a Hilti forum to share the most exciting results of the quarter
• Performed data analysis in one of the key manufacturing processes. Identified and developed different use cases that helped the company improve lot quality and refine manufacturing process

March 2021 - May 2021

Qiagen
Data Scientist Intern

Qiagen | Barcelona, Spain

Performed several data analysis and data science tasks.

• Designed and built an SQL-based Grafana server to control the main manufacturing process KPIs. Ideated and implemented machine learning algorithms to predict future failures leveraging time series models
• Revamped an R program originally designed to control the leak test, re-enabling the company to instantly measure possible leakings, leading to a time reduction of 5 man-hours per week and an improvement in output robustness
• Upgraded the main C# application that controlled the manufacturing process, reducing computing time by 8%
