Why did you choose to do a PhD?
1. I enjoy exploring new knowledge, working with insightful people
2. My prior internship experiences make me realize that doing repetitive work is not what I want. I would like to involve in more challenging and novel projects.
Why did you choose to do graduate education at NUS? If you received offers from other universities, why did you pick NUS?
1. My undergraduate study is in NUS
2. I like the research atmosphere in my supervisor’s lab
Briefly share about your research or thesis (i.e. dissertation topic for Masters by Coursework students).
Phishing attack is one of the most common cyber attacks, causing huge financial losses every year. Prior approaches on phishing detection achieve good performances on experimental datasets. However, they are either not generalizable to wild webpages, or unable to explain its model decisions. Our research is aiming at developing a systematic phishing detection framework to: 1) achieve high precision and recall in field study 2) provide user-friendly explanations with CV techniques 3) actively adapt to human feedback.
If you have won any academic prize/competition or been invited to speak at an international conference—share what it is, its significance, and how you worked towards achieving it.
