M. S. Al-Ghamdi completed his B.Sc. degree from the Department of Physics at King Abdulaziz University, Saudi Arabia in 2000. Following this he spent a couple of years in working as teacher assistant for King Abdulaziz University. Between 2003 and 2010 he travelled to the UK doing his postgraduate studies at the school of physics and astronomy, Cardiff University, where he completed his M.Phil. and Ph.D. degrees in optoelectronics in 2006 and 2010 respectively. He then returned to Saudi Arabia where he got position at King Abdulaziz University as an Assistant Professor. Then he started to build a group in optoelectronics with a new laboratory while he is still working with other research groups, as a visiting researcher. His research interest includes the design and fabrication of semiconductor devices laser diode and studies the optoelectronic properties of these devices by measuring their absorption, spontaneous and stimulated emission spectra. The current research topics include red emitters’ quantum dot laser diode which is used in photodynamic therapy of cancer and also used in the manufacture of dual wavelength sources. He is a member of IEEE, APS, OSA and IOP societies. M. S. Al-Ghamdi completed his B.Sc. degree from the Department of Physics at King Abdulaziz University, Saudi Arabia in 2000.
