About Me

I have always had a passion for working with data, even during my previous career in engineering.
With 14 years of experience in polymer processing, I have gained invaluable expertise in the field of extrusion,
injection molding, foaming, and compounding processes, which serves as a strong foundation of
domain knowledge. (Please refer to Curriculum Vitae for full details)
However, my true calling emerged when I delved into the world of Data Science from 2021 to 2022.
Exploring the vast realm of data analysis and predictive modeling, I discovered a profound fascination for the field.
Ever since then, I have become an ardent advocate for Data Science, leveraging its power to unlock fresh perspectives within my previous research domain.
Join me on my homepage as I explore the exciting intersection of data and engineering.
