I have an interest in developing algorithms or software that can have a positive impact on people and also challenges my creativity and problem solving capabilities. With this in mind, cryptography is the focus of my research as computer security will always be of major importance. I also love teaching, helping students to develop skills that will aid them in their future endeavors.

Orang Asli Tangkai Cermin Workshop
National Instruments Robotics Competition
Bengkel Siswa Lestari

The School of Computer Sciences, USM holds a workshop for the first year students every year, to equip them with valuable soft skills and to motivate them in their studies in the upcoming years. I was given the opportunity to host this workshop for three semesters, whereby I brought speakers from start-up companies such as Piktochart, Telebort and Poladrone, as well as motivational speakers and trainers to give talks to the students. 

Orang Asli Outreach 1.jpg

As part of a community outreach program by the School of Computer Sciences, USM, I conducted a simple programming workshop for the primary school children at the Tangkai Cermin Orang Asli settlement. It was a unique experience because I went into the class expecting to teach them simple drag-and-drop scripting but instead had to start off by teaching them how to use a computer mouse. It was a humbling experience and a load of fun. The students did amazing and loved the sessions. They even told me that they wanted to do it again the next day. I would love to organise this workshop again if I were to be given the opportunity. 


In 2018, I led one of two teams from the School of Computer Sciences, USM to compete in the National Instruments Autonomous Robotics Competition. Despite having no engineering or hardware knowledge, our team managed to get into the semifinals and competed against teams from the engineering campus. Although we didn't win, it was a good experience for the students. This year, I am leading yet another team for the 2019 competition.


In 2018, I was involved in the CSGuru initiative started by Telebort Technologies, offering free coding classes to school children. As part of this initiative, I helped to recruit volunteer "gurus" to teach these coding classes. There was a good response from the Computer Science students and it was good to see them having fun while teaching the school children. Through this program, the students learned valuable people skills and also improved their own understanding of programming through teaching.
