Biography:
Dr. Saif Islam was born in Bangladesh and received his B.S. degree in Physics from Middle East Technical University, Ankara in 1994 and M.Sc. degree in physics from Bilkent University, Ankara, Turkey in 1996. He received his M.S. and a Ph.D. in electrical engineering from the University of California-Los Angeles (UCLA) in 2001. Before joining UC Davis in 2004, Dr. Islam worked at Hewlett-Packard Laboratories, Gazillion Bits Inc. and SDL Inc./JDS Uniphase Corporation as a Staff Scientist, Senior Scientist and Post Doctoral Research Fellow. 

Research Background
Dr. Islam has conducted research in the areas molecular electronic devices, semiconductor nanowires, ultra-fast photonic devices, high-power and linear gain-clamped semiconductor optical amplifiers, fiber optical communication systems, and RF photonic devices and links,  He was the first to demonstrate the distributed balanced phtodetectors and a record high linear photocurrents in a photodetector with a ultr-afast response. He also worked on the first demonstration of ultra-fast resonant cavity enhanced Schottky photodiode. Dr. Islam developed the technique for generating ultra-smooth metal surfaces for interfacing molecular electronic devices and helped dramatically improved device yields. Recently, he demonstrated the first semiconductor nanowire bridging technique which solves the longstanding issue of interfacing one-dimensional quantum wires.    

Current Research Focus:
Dr. Islam's research focuses on the incorporation of low-dimensional nanowire devices with conventional IC elements, employing processes compatible with mass-manufacturing. Unlike the research-based approach of sequentially connecting electrodes to individual nanowires for device physics studies, massively parallel and manufacturable interfacing techniques are crucial for reproducible fabrication and incorporation of dense, low-cost nanodevice arrays in highly integrated material systems.  Dr. Islam has developed two novel nano-device integration and mass-production techniques termed 'nano-bridges' and 'nano-colonnades' that are entirely compatible with existing microelectronics fabrication processes. His research objectives are now  to develop nano-structures integration processes and explore the applications of nano-devices in bio-chemical sensing, photonics, memory and logic devices for computing.
