Research

Acoustic shape optimisation

I explore artificial intelligence methods (metaheuristics, machine learning) for the shape and topology optimisation of lightweight mechanical structures especially sound-absorbing porous material structures.

Interactive Demos


I find happiness in helping students understand complex technical concepts deeply. I make interactive web demos to make learning fun. Check them out if you are interested.🙂

Fascinating concepts

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 ! 🙂

    Game perspective

    Game perspective is the paradigm of learning through games or interactive demos. While this is not a replacement for conventional learning (books, lectures, exercises), it is a valuable alternative teaching method.

    With the ever-growing forest of human knowledge, there are too many exciting things to learn, and life is too short.

    With the help of games or interactive demos, 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.
