What sparked your interest in your field of work?
My interest in aviation was ignited by its global impact and the pivotal role it plays in connecting Singapore to the world, bridging people and economies. What drew me to CAAS was the opportunity to go beyond my education and work on strategic projects that shape the future of aviation, both locally and globally. The prospect of contributing meaningfully to areas such as air hub development and collaboration among various entities in the aviation sector, while learning from key aviation professionals, continues to inspire me in this ever-evolving field.
What made you apply for the CAAS Overseas Undergraduate Scholarship?
Apart from the attractive opportunity to study abroad, I was intrigued by the different roles and responsibilities at CAAS. The prospect of working in different roles that interface with various parties including the airport operator, airlines, ground handlers, and other agencies in the Singapore Government greatly appealed to me, as it offered a comprehensive understanding of the aviation sector and a chance to contribute to its growth.
How has the scholarship contributed to your personal and professional development?
The scholarship enabled me to pursue an undergraduate degree in applied mathematics and economics, followed by a master’s in public affairs. My time spent living and travelling abroad, gave me the opportunity to explore subcultures and niche interests that I would not have otherwise encountered locally. Professionally, it equipped me with both quantitative and qualitative skills that are crucial in my current role. My internships provided meaningful opportunities to work on impactful projects, offering valuable insights into the work of CAAS and the broader aviation industry. My growth as an officer would not have been possible without nurturing mentors and a strong network of friends at CAAS.
CAAS also provides a nurturing environment for officers to support their professional growth in areas such as collaboration and project management. Through cross divisional activities such as chairing the CAAS Family Day committee and assisting the planning of the CAAS Dinner & Dance, it has helped me to build stronger connections with my colleagues at CAAS.
Could you elaborate on your role at CAAS?
In my role at the Airport Economic Regulation (AER) Division, I am part of a team that oversees price regulation for Changi Airport. This includes reviewing aviation-related charges for Changi Airport that support key investments and operations that allow Changi to remain competitive and meet rising air travel demand. My primary responsibility is to carry out research and analysis to develop policy recommendations that facilitate decision-making for management and senior government officers.
I enjoy taking ownership of research-focused projects. One example was a project to compare Changi’s aviation charges with other airports. This required me to analyse equivalent fees and fee structures at other airports, and challenged my qualitative and quantitative skills.

We regularly monitor the air hub’s performance, to allow us to respond nimbly and make adjustments as needed, to ensure the air hub’s competitiveness.
Looking ahead, what aspects of your work are you most excited about?

By working collaboratively with different stakeholders—such as regulatory bodies, industry partners, and tech innovators—we can drive progress for Singapore’s aviation sector. I look forward to being a part of projects that encourage collaboration and enhance how we operate, ultimately helping to create a more efficient, innovative, and safe aviation environment.
