Biografi Singkat

Wardhana is Principal Research Scientist at Singapore-MIT Alliance for Research Technology. He is leading the research activities on the reliability of compound semiconductor based devices. He uses advanced microscopy techniques such as transmission electron microscopy (TEM), electron energy loss spectroscopy (EELS), and photon emission microscopy (PEM) to understand how devices fail and then propose ways to improve the reliability. He has served as Technical Chair of IPFA 2018 and 2019. Wardhana received his B.Eng (Materials) from Nanyang Technological University in 2007 and PhD in Advanced Materials for Micro-and Nano-systems under Singapore-MIT Alliance Program in 2012.
