This interest should be based on your own passion, not the current trends. Interest is an important factor in deciding to pursue a Ph.D. because you have to like the topic and like it for a long time. A Ph.D. will require you to dive deep into a subject you must be genuinely curious about.\u003C\/p\u003E\u003Cp\u003ESecond, we are in a new era with rapid advances in information technology. Time is an invaluable resource and is shaped by technology. You have to think more about your time, consider where and how you spend it, and embrace ways to use it more efficiently.\u0026nbsp;\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003ECan you tell us more about your hobbies and how you keep up with them?\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EI started learning violin when I was five years old, and magic tricks when I was 11. The brain is a supercomputer suitable for functional computation. Our brain is an interface between the objective and subjective, where computation plays a core role in integrating these exact mechanics into interpretations of the world. This realization was one of the important factors that inspired me to pursue my Ph.D. research in computational neuroscience.\u003C\/p\u003E\u003Cp\u003EAnother comparison I\u2019ve learned after playing violin for 23 years is that the cochlea in our inner ear is a fast Fourier Transformer that simultaneously computes the aesthetic of music for us. Performing magic tricks for 17 years taught me that all the occurrences of seemingly low-probability magic phenomena are achieved by either letting it be a certain event or exhausting all possibilities.\u003C\/p\u003E\u003Cp\u003EI also have other hobbies, like yo-yo balls. I enjoy performing all these skills in front of audiences. Performing brings me satisfaction when I see excitement and happiness from the people I entertain. I am very grateful to my parents for their cultivation and encouragement in doing things that bring me fulfillment. They taught me to be curious and explore my interests, to enjoy pastimes, and instilled the habit to not give up my passions. These were not secondary things that distracted me from coursework or Ph.D. research, but rather complementary parts of my life that bring out the best in me.\u003C\/p\u003E\u003Cp\u003E\u003Cstrong\u003EWhat is your favorite Georgia Tech memory?\u003C\/strong\u003E\u003C\/p\u003E\u003Cp\u003EI have a lot.
