Sima Dimitrijev is a Professor at Griffith University in Australia. He is an educator, a microelectronic engineer, a researcher, an inventor, and the author of two textbooks. Sima has led many research and development projects, funded by industry, governments, and venture-capital investors. In addition to the textbooks on semiconductor devices, published by Oxford University Press, New York, and translated into Korean and Chinese, he has published 180 papers in peer-reviewed journals and many papers in conference proceedings. Sima’s peer-reviewed papers appeared in more than 40 different journals, many of them publishing seemingly disconnected areas of scholarship—from crystal growth to cognitive memory networks and intelligent systems. This unusual spread of scholarship across different areas of expertise matches the unique depth that “Trial, Error, and Success” seeks to convey.
