Work/Research Interests

• Web and mobile web
• Content delivery to mobile devices
• Applications like streaming video and Voice over IP (VoIP) on mobile devices
• Services ( e.g., location based services, emergency services ) on mobile devices
• Design and development of (mobile) web applications.


• Networks, Wireless networks, specifically WiMAX networks
• Overall architecture
• WiMAX devices, scenarios, network entry, security, etc.
• Interworking among different wireless and wireline networks.
• IP networks


• Computer vision and machine learning

I also worked extensively in computer vision and learning and published many research papers in that area. My work in this area involved applying machine learning methods to

• Many vision tasks like face detection,
detection of objects of many classes (like cars, motobikes, etc.)

• Face detection and identifying facial expression (like happy, surprise, etc.).
• Face recognition, identifying make and model of cars.
• Robot navigation.
