Oleksandr Fialko, Data Scientist, Qrious
(CSDA Research Fellow 2017-2018)
Oleksandr joined CSDA with a PhD in physics and a strong mathematics and computing background, keen to pursue a growing interest in data analytics and machine learning.
He saysCSDA provided an excellent opportunity to gain data science experience by working on important and useful applications of predictive analytics. Working under supportive and friendly management, and the chance to travel internationally as part of project work added to his enjoyment of the role.
Oleksandr says the skills he picked up at CSDA were useful in securing, and his new role:
“At CSDA I gained the ability to work with messy real life data and cutting edge machine learning models. I also came away with a deeper understanding of the ethical and moral responsibilities that are part of working with predictive analytics."
