Research interests of CT&T are in the broad area of communication theory with a particular emphasis on the physical layer design aspects of wireless communication systems in radio and optical frequency bands. Current research topics are listed in the following:

Visible Light Communications (VLC)

• Channel modeling for indoor, vehicular and underwater environments
• High-speed physical layer design for VLC systems
• Machine learning for VLC system design
• Coherent VLC transmission/reception 
• Energy harvesting VLC
• Underwater VLC
• Vehicular VLC

Free Space Optical (FSO) Communications

• Airborne FSO-based backhauling
• Digital signal processing for coherent FSO systems
• Relay-assisted FSO systems
• Diversity techniques for FSO systems
• Adaptive FSO systems
• Hybrid RF/FSO systems
•
