Profile Summary

Gagus Ketut Sunnardianto is a senior researcher and a member of the Quantum Simulation 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, focusing on the variational quantum eigensolver (VQE) for molecular optimization.
