About Eason

Hi, I’m Eason from CMU HCII. In high school, I was a problem student, frequently skipping class and engrossed in gaming for over 12 hours daily. Surprisingly, gaming taught me the value of deliberate practice. Applying these strategies, I transformed my academic performance, earning numerous awards at my undergrad. These experiences inspired me to research in Learning Sciences and Human-Comter Interaction, eager to discover productivity-enhancing educational tools. Ultimately, I aim to help others reach their full their potential through education. Additionally, I’m intrigued by the fair and transparency offered by Blockchain Technology and have three years of Web3 industry experience.

Software Engineer at Cohart
June 25, 2022, Khánh worked with Eason on the same team at Cohart
I have been working with Eason for a few months now. It was my job to integrate his work on Cohart’s NFT minting smart contracts. I had no trouble reading and applying his works since they were well-documented and easy to understand. He has also been very supportive.

Eason is always well-structured, fully-prepared, and excellent at presenting his work. I was also impressed with his calm and positive attitude when we encountered any issues.

It was a pleasure to work with him and I highly recommend him to anyone who needs to research and develop blockchain, machine learning, or AI.

Yuen-Hsien Tseng
Distinguished Professor at National Taiwan Normal University
May 22, 2022, Yuen-Hsien was Eason’s undergraduate thesis advisor at NTNU
Eason is the most clever and diligent student I have ever seen so far. He is enthusiastic about learning techniques and applications, such as Education, AI, NLP, and Blockchain, and has developed quite a few applications that impressed me.

Moreover, He did not only develop application systems quickly but also evaluated their use in practical applications based on what he learned in his major, i.e., Learning Sciences.

Lastly, He also devoted himself to scientific paper writing and therefore has several papers accepted in refereed international conferences. I have never heard of any undergraduate students in Taiwan who could have more than 7 papers accepted before their graduation, except Eason.

Eason is a very talented, energetic, and self-disciplined person who gives 100% focus on things he is interested. During his work with me, he has demonstrated a great level of creativity with a great mentality for entrepreneurship. He is also a fast learner and loves discovering new technologies with strong desire for new and more knowledge. He possesses a huge potential to be explored and guided with a creative mind. He does have few areas to be further improved but I believe with right mind set, he will easily grow to the next level with no doubt.
