''I believe that we cannot build a majestic castle on the sand - that is why a fundamental study is important for the future of material sciences''

Dr. Yuttapoom Puttisong holds a senior lecturer position in Functional electronic Materials at Linköping university. His Ph.D. thesis focused on utilizing spin functionality of defect centers in a semiconductor for spintronics and quantum information technology. In 2015, he was awarded an international Postdoc Grant from Vetenskapsrådet (VR), the largest government research funding body in Sweden, to join the research group at Cavendish Laboratory at the University of Cambridge, UK. After he returns to Linköping University, he received a starting grant from VR awarded to an independent young researcher. In 2020, he secured research funding from the Swedish Energy Agency. He is now starting a new research team under the research environment of EFM-FEM.
His research focuses on spin functionality in energy-related materials for solar cells and white-lighting applications. He applies spin and quantum phenomena to answer long-standing questions related to the efficiency bottleneck in the solar cells and organic light-emitting diodes (OLEDs). Current projects are optimizing singlet fission yield for efficient solar-energy harvesting and investigating new spin-management designs of the next generation OLEDs.

He also pays great interests in new perovskite crystals with magnetic ion doping and envisages them as potential candidates for the spintronics and quantum computation application 

He believes that for great sciences, one must bring together interdisciplinary skills and fruitful collaboration. He has actively participated in many projects, in and outside Linköping University, whenever his expertise in spin-dependent phenomena is in need.

Yuttapoom Puttisong teaches first year physic students at LiU.
