Context. A word that is hard to define if we don’t know the “context” to which we are referring. Systems and interactions with such systems are more meaningful, useful, usable and efficient if context is considered as a core element in the system design. Context is also a very important aspect to consider in modern day computing, because of the Internet of Things (IoT). IoT devices have ‘pervaded’ into our daily personal and work lives. It has reached a stage where we don’t consider them to be ‘assisting’ devices any more. They are usually a significant part of our lives. My research interests stem from the above factors, i.e. the need for us to adapt our interactions to the ubiquity of devices, the context of use, and the security/privacy issues resulting thereof.
Pedagogy – Why do people use different strategies to learn? How can we help them learn more effectively?
Privacy/security – What can we do to ensure that users’ privacy is protected in their various daily interactions?
IoT for social good – How can we ensure the personal safety of users as they go about their daily activities?
Note: This student pursued an internship-based MACSc and a research project was optional.
He, however, worked extensively in the research project on personal safety in which he was co-supervised with Dr. Kirstie Hawkey.
Note: He was also mentored by Dr. Mike Just (Heriot-Watt University) and Dr. Alette Willis (The University of Edinburgh).

Co-supervised with Mr. James Fleming.
During May 2015 – August 2016, I was a postdoctoral fellow at the Faculty of Computer Science, Dalhousie University. My work was sponsored by Boeing.
Research focus: Human aspect to security and privacy, particularly in applications employing IoT and mobile devices to create a ubiquitous and coordinated work environment.
Supervisors: Dr. Derek Reilly and Dr. Srinivas Sampalli.
Additionally, I worked with Dr. Kirstie Hawkey to explore using Micro Expressions as a possible supplement to Face Recognition. This project was the result of a personal interest towards understanding the working of the human mind, which in a way, led me to consider psychological/behavioural aspects that could make user interactions/reactions unique.
My thesis focused on Security (key management and authentication) and Applications in Emerging Wireless Technologies (with a specific focus on RFID and WBAN).
My doctoral work involved creating a metamorphic (or, reconfigurable) security framework, which dynamically ‘switched’ between three new key management algorithms and encryption schemes proposed as part of my thesis work. The objective here was to create security solutions that seem complex to understand/crack, are simple to deploy, but offer security through obscurity. You can find more information about my PhD work here on this page.
Thesis advisor: Dr. Srinivas Sampalli.
My doctoral work was sponsored by Boeing, as part of a collaborative venture between The Boeing Company, and Dalhousie University [Click here for the related news item on the Boeing website].
There seems to be an unavoidable relationship between the lack of adequate medical facilities in rural India, and the risks due to any complications in pregnancies on the lives of the mother and the unborn fetus. My work focused on proposing an application to remotely monitor women with high-risk pregnancies, and to ensure reliable and secure communication between the WBAN sensors and the hospital monitoring station.

Our objective in this project was to assess the attributes of a city, particularly those that have been classified as “Knowledge Cities” around the world, and to develop a framework that would help in assessing cities in developing economies such as India. Our initial work involved assessing the attributes of the Indian city of Mysore and positioning it as a knowledge city. Next, we proposed a framework to assess and position a city in developing economies as a knowledge city, with Mysore used as a case study.
During my time at the Faculty of Computer Science, I have been actively involved in a number of projects. I list a few of those here.
We created an interactive web application and an informative Android application for spreading awareness about diabetes at information booths (at Dalhousie University and NSCC, Dartmouth) on World Diabetes Day 2014. This project was in collaboration with Capital Health.
We created an interactive web application to be deployed at the Halifax Pride Parade 2014. This project was in collaboration with prideHealth.
We worked on assessing a healthcare solution for its conformance to standards. This project was in collaboration with Health QR.
We worked on an intuitive solution for mobile couponing. This project was in collaboration with Citrus Mobile Solutions.
Prototype development of Home Safe Living System, a software system that will expertly assess a geriatric patients ability to either live independently or with the assistance of a caregiver, and recommend the necessary changes. It considers patients level of physical and cognitive abilities to generate a health profile. The project is funded by NSERC Engage grant.
Home Safe Living provides solutions for independent living of elderly people. In this project, we conducted a feasibility study of company’s requirements to develop a software system which will capture the health profile of a client / patient and helps in assessing their ability to live either independently or with the assistance of a caregiver, and recommend any additional requirements. Our proposal includes designing of an knowledge-based expert system with web-based interface.
This is a novel social application to capture or use images that are present in the phone memory, and manipulate the images, and share the images in the user’s social group.
This is a novel application to share and view images between two Android devices. The application used Bluetooth for sharing the images between the devices, and used a modified handshaking protocol for exchanging important information between the paired devices to display the images appropriately.
In this study, we studied the various parameters associated with a knowledge city, developed an index to effectively assess the positioning of cities in emerging economies as knowledge cities, and analyzed Mysore city, India in terms of the developed Knowledge City Index (KCI).
