Acoustic shape optimisation

As part of the Computational Optimisation and Learning Lab (COL) at UoN, I study the mechanical shape and topology optimisation using artificial intelligence methods (metaheuristics, machine learning) for lightweight sound-absorbing solutions.


Check out some interactive web demos I've made and have fun! I find happiness in seeing the enlightenment in one's face when they truly understand something. I have figured that I am cut out for teaching and I aspire to be an excellent teacher someday. :-)

I am fascinated by science and nature. I love learning new and interesting concepts. If you do too, you might like a compilation of concepts that I found fascinating. If you think I should check something out, let me know ! :-)

    Vision

    Game perspective is the paradigm of learning through games and interactive demos. While this is not a replacement for conventional learning (books, lectures, exercises), it is the most under-utilised teaching method.

    With the ever-growing forest of human knowledge, there are plenty of things to learn, but life is just too short.

    From a game perspective, I believe knowledge could be assimilated faster and in a more fun way allowing us to learn more in a given lifetime. Check out some of my works available in the web projects section. Thanks to Luc Jaouen for inspiring me to make these. Check out his works at Acoustic Porous Material Recipes.

    A shoutout to Dan Russell for his amazing work.

    Concepts that fascinate me

    These are some of the concepts that I found intriguing. It is always interesting to ask people what concepts fascinate them the most, as I always learn something new. Every person has their own list, and here is mine. If you think I have missed something, let me know. :-)
