Profile Summary

Gagus Ketut Sunnardianto is a senior researcher and group leader of the Quantum Finance & Complex Systems research group. He earned his doctoral degree from Osaka University in Japan in 2017. He initially conducted DFT calculations on graphene for hydrogen storage applications during his doctoral studies. Since then, he has expanded his research into molecular dynamics (MD) simulations related to hydrogen embrittlement in steel. More recently, he has developed an interest in quantum computing, with a focus on the variational quantum eigensolver (VQE) for molecular optimization. His current research also explores quantum algorithms in the financial sector. Students interested in internships related to quantum algorithms and their applications in finance and chemistry are welcome to apply.
