Prospective students may write for Masters’ (M.Sc.) or Doctoral (Ph.D.) programs in the areas related to Photonics/Optical Waveguides. Topics include wave propagation in complex structured optical mediums, metamaterials and the growth of nanostructured thin films for optical biosensing and/or biometric reading.

A fellowship for Ph.D. student is currently available.

 

MENTOR

My academic life was spent in different universities in India. To me the most respected person has been my revered teacher – The Late Professor Prasad Khastgir – who put real efforts by head and heart in shaping my life. He was a man having strong belief on truth and wisdom. I still remember his words – “A man is first a Man, and then a Scientist.” I feel myself greatly fortunate as my fate brought me under the eminent guidance of such a great personality who was a real torch bearer for me; teachers like him are rare.

 

BIOGRAPHY IN BRIEF

Pankaj Kumar Choudhury’s academic life was spent in different institutions in Varanasi (India). He started research career in 1989 from the Department of Applied Physics, Institute of Technology (IT), Banaras Hindu University (BHU, Varanasi), and received a Ph.D. degree in 1992. From 1992 to 1997, he worked as a Research Associate at the Department of Electronics Engineering (IT, BHU). Also, during 1995–1996, he was a Guest Lecturer in Physics at the Faculty of Science and Technology, Mahatma Gandhi Kashi Vidyapith (Varanasi). In 1997, he joined the Department of Physics, Goa University (Goa, India) as a Lecturer, where he was for a couple of years until 1999. In 1999, he became a Researcher at the Center of Optics, Photonics and Lasers (COPL), Laval University (Quebec, Canada), where he worked on the fabrication and characterization of ferroelectric optical waveguides. During 2000–2003, he was a Researcher at the Faculty of Engineering, Gunma University (Kiryu, Japan), where he worked on the electromagnetic behavior of complex-structured optical waveguides and sensing. In May 2003, he received the position of Professor at the Faculty of Engineering, Multimedia University (Cyberjaya, Malaysia) where he was until late 2009. During the span, he also served the Telekom Research and Development (TMR&D, Malaysia) as a consultant for projects on optical devices. In 2009, he became Professor at the Institute of Microengineering and Nanoelectronics (IMEN), Universiti Kebangsaan Malaysia (The National University of Malaysia, Malaysia). His current research interests lie in the theory of optical waveguides, which include complex mediums, fiber and integrated optics, fiber optic devices, optical sensors and metamaterial properties. He has published over two hundred forty five research papers in peer-reviewed international journals and conference proceedings; contributed chapters to sixteen research level books; edited and co-edited seven research level books in these areas. He is the reviewer for nearly three dozen research journals. Also, he serves the Editorial Board of International Journal of Humanitarian Technology (Inderscience Publishers, Switzerland). He is the Section Editor of Optik – International Journal for Light and Electron Optics (Elsevier, The Netherlands) and the Editor-in-Chief of the Journal of Electromagnetic Waves and Applications (Taylor & Francis, UK). He is Senior Member of the Institute of Electrical & Electronics Engineers (IEEE), the Optical Society of America (OSA), and the Society of Photo-Optical and Instrumentation Engineers (SPIE).
