Chun Yu, Ko

Deputy Data Team Lead
Experienced Data Analyst with 8 years in the field, I specialize in bridging data with strategic decision-making. My expertise includes advanced analytics, causal analysis using statistical and Pre-trained Models, and transforming complex data into actionable business insights. I'm recognized for my leadership in guiding teams towards innovation and growth, advocating for passion and collaboration. Eager for new challenges, I aim to leverage my skills in larger markets to drive continuous personal and professional development. I have a strong interest in causal discovery and have recently been experimenting with using Pre-Trained Models to assist in causal analysis. However, the field of causal discovery has not yet significantly benefited from the rapid advancements in LLMs or Transformers. I believe there is still a vast scope for innovation in this area. Consequently, I am currently enhancing my understanding of algorithms for causal discovery. Simultaneously, I am exploring opportunities for integrating causal discovery with LLMs to leverage their potential in this domain.

I continuously learn with new methods at work, but I believe it's important to create an environment for ongoing learning outside of work as well. Therefore, I chose to enroll in a in-service master's program. This has provided me the opportunity to interact with professionals from various fields, gaining diverse perspectives on data science, and allowing me to delve deeper into data science in my spare time.

I did not complete my degree. At the beginning of my senior year, I came across a research project on AED (Automated External Defibrillator) geographic location studies being conducted in a laboratory. At that time, I decided to temporarily pause my studies, but joined the same university as a Research Assistant to pursue research that interested me.
