Queensland University of Technology
I’m currently pursuing my PhD at the School of Mathematical Sciences at Queensland University of Technology, specialising in optimisation. I earned my BSc (Hons) in Transport and Logistics Management in 2018 from the University of Moratuwa. After completing my bachelor’s degree, I worked as a demand planner and logistics analyst, blending analytical decision-making with real-world applications. Following over three years of industry experience, I spent three years as a Demonstrator and lecturer at the University of Moratuwa. During this time, I also completed my MSc in Operations Research at the same university, aiming to deepen my understanding of optimisation techniques that complement my undergraduate studies. I am passionate about mathematics and analytics because I love how they can be practically applied to turn complex processes into more efficient, impactful, and sustainable solutions.
Give me a quick overview of the type of mathematics you are studying, and/or the aims of your research and its potential applications/outcomes (how you would explain your work and studies to friends who don’t study maths?)
I am focusing on operations research techniques, particularly optimisation methods for real-world decision-making. My current aim is to develop innovative approaches to vessel scheduling and berth allocation in resource-constrained, high-traffic seaports. This helps improve efficiency, fairness, and sustainability, ultimately resulting in more resilient and smarter port operations.
How did you get into the mathematical sciences? Was there someone or something that inspired you to this field?
Although I was not a top-performing student overall, I have always been fascinated by mathematics and consistently achieved top marks in the subject, a curiosity first recognised and nurtured by my Grade Three teacher. I genuinely enjoyed solving analytical problems, which motivated me to pursue the mathematics stream in my advanced-level studies. Later, during my undergraduate research, under the guidance of my supervisor, I discovered my true enthusiasm for research. These experiences have fuelled my passion for research and strengthened my desire to use mathematics to address meaningful, real-world problems. I am deeply grateful to my parents, teachers, supervisors, and friends, whose encouragement and inspiration have shaped my journey.
Winter School is designed to give students a deeper understanding of their area of research and expose them to others working in different fields/industries. Tell me about your Winter School experience. What was the most valuable part of the program for you?
I really enjoyed Winter School as it provided me with valuable knowledge and a wonderful chance to meet new people. I appreciated seeing how mathematics is applied in different fields to solve complex problems. The friendly and approachable lecturers made it easy to ask questions and join in the discussions, which even sparked some ideas for my own studies. I also had the pleasure of meeting fellow students working on a variety of research areas, sharing ideas, and working together. It was a truly enriching experience that broadened my perspective and inspired me.
What was your main take away/s from AMSI-MATRIX Winter School? Something you learnt? A connection you made? Do you have new ideas for your work/research or see it in a new light?
During the lectures and tutorials, I had the opportunity to learn new concepts and tools related to mathematical optimisation, which have been incredibly helpful for my ongoing research. I also discovered some exciting potential career paths for PhD holders. Attending the AMSI Winter School participant talks gave me wonderful insights into how to communicate research effectively, especially when explaining complex ideas. The support and encouragement from fellow students inspired me to present with confidence, and the helpful feedback from native speakers highlighted areas where I can improve even more.
You received a grant to attend AMSI-MATRIX Winter School. How important was this in terms of your ability to attend, fully participate in the program and meet others studying in similar fields?
Receiving the grant was vital in enabling me to attend in person, especially since I was travelling from Queensland. Without this support, I might not have been able to make it. The grant not only eased the financial side of things but also helped me engage fully in the programme and make meaningful connections.
What advice would you give to someone who is considering applying for Winter School? How would you describe the conference to them?
The Winter School not only provided new knowledge relevant to your studies but also offered valuable insights into potential career paths, opportunities to establish new connections, and a broader perspective on the field. If you have the chance to attend in person, it is even more valuable.
Where do you want the mathematical sciences to take you? Where do you see yourself in five, ten years time?
In five to ten years, I see myself sharing my knowledge as a lecturer while contributing to solve real-world problems through research, applying my skills across both academia and industry.
Any other feedback/comments you would like to provide on the travel grant or AMSI-MATRIX Winter School?
I am deeply grateful to the AMSI-MATRIX Winter School organisers for creating such a memorable and enriching experience.
