Personal Statement

Upon my arrival to Strathclyde in January 2008 I started new research initiative in organic electronics focusing on low-voltage organic thin-film transistors with ultra-thin, bi-layer dielectrics with total thickness of ~ 10 nm. The fabrication process is completely dry and amenable to roll-to-roll processing. We are now developing flexible thin-film sensors based on ferroelectric PVDF co-polymer for electronic skin and wearable electronics.

Previously with the Department of Electrical Engineering of Princeton University (1993-2007), USA,  I pioneered the fabrication of thin-film silicon transistors on flexible glass and plastic substrates, introduced electrophotographic printing into electronic device fabrication, developed the first experimental correlation between the thin-film transistor performance and applied mechanical strain, derived the mechanical theory of thin films on foil substrates to control misalignment in flexible electronics, and made seminal contributions to the defect physics of hydrogenated amorphous silicon. I have co-authored 11 patent groups/applications, 5 book chapters and about 100 technical papers. I also directed a mid-size university microfabrication facility with 100+ users for 7 years.  I am a Senior Member of IEEE and member of Materials Research Society (MRS) and Society for Information Display (SID). 

Expertise & Capabilities

  • Flexible, low-voltage organic thin-film transistors and sensors
  • Ferroelectric PVDF co-polymer and its application to sensing
  • Electro-mechanical behaviour of flexible thin-film electronics
  • Electronic device fabrication using standard and novel techniques
  • Broad range of material growth and characterization techniques

Teaching Interests

I am involved in several core modules in the first and second years.  The classes are large and the student population is composed of students studying on four different degree programs.  Consequently, my teaching methods cover traditional and innovative lecturing, hands-on tutorial support, weekly on-line quizzes with instant feedback, and laboratories requiring mandatory preparation and active participation.   

My taeching duties are:

EE105  PDP & SGT    

EE269  Electronic and Electrical Principles 2     

EE271  Electronic and Electrical Techniques and Designs 2     

Research Interests

  • Integration of thin-film devices with flexible substrates
  • Electrical response of thin-film electronics to mechanical strain
  • Novel device fabrication processes including printing and roll-to-roll fabrication
  • Low-voltage thin-film electronics
  • Electronic skin and tactile sensing
  • Electrically conducting biogels

Industrial Relevance

Curved TV screens, non-breakable displays in smart phones, functional electronic sheets that can be rolled out for occasional use, and electronics embedded in clothing are just a few examples of the recent R&D in the electronics industry. All these upcoming applications have been enabled by the changing form factor of the electronic circuits that is moving from strictly planar to curved, flexed, stretched, and draped. Such step change has been enabled by materials developed in the recent years -- organic polymers and oligomers, metal oxides, bio-functional materials, etc.
