In Las Vegas, I had the opportunity to attend DEF CON, one of the world’s largest hacker conferences. Beyond the technical talks and security research, it was exciting to experience the unique atmosphere of the hacker community firsthand and meet people with diverse interests and backgrounds. The trip became a memorable experience that combined cybersecurity, new perspectives, and the distinctive energy of Las Vegas. 

In Hong Kong, I had a serendipitous encounter with a local stranger while asking for directions. He kindly volunteered to be my guide for about 2 hours, showing me around the city including the filming location of "Chungking Express" (right photo). I'm deeply grateful for his generosity and the wonderful memories we made together.

I attend the IEEE BigData2025 poster session. I show my research about defending AI supply chain attack.

This is a memory from when I was a member of Hyundai Autoever and attended the ICMC, a post-quantum cryptography conference. I heard a lot of good research and got to see a lot of Canada.
