Research



My research activities focus on learning from the real-world objects and phenomena and devising intelligent automated systems to improve the quality of life. I investigate the connections between media and mind and between life and technology. I experiment on how different types of information and their presentation can bring changes to human life. Although I am a passionate learner of Computer Science, my research interests are very much inter-disciplinary. The goal of my research is to discover the facts hidden inside the incidents happening around us in every moment and exploit those to devise technologies for helping people.

I work on Artificial Intelligence, Data Mining, Human-Computer Interaction, Multi-modal Communication, Psychology, Art, Design, Maps, Multimedia, Geometry etc. I also study trust, security and privacy in different systems. I often have to study public health issues, government policies, cultural and social issues and their variations with the geographical changes. Reflections of my works, thoughts and studies are sometimes found in my formal and informal publications, talks, lectures and blogs.

Professional Activities:

Here I present the basic areas of my research works each of which has a pointer to the projects related to that.


Autism Spectrum Disorders (ASD) are defined by the abnormal behavior of human beings in course of social communication. The abnormal cerebral structure of the people diagnosed wit ASD limits their ability for socialization at their early age. The traditional methods for assisting the autistic children suffer from various practical challenges and are not effective. Hence, we try to make attractive and effective means of E-Learning for the autistic children. We have developed a number of computer games which need the children to exhibit their skill in speech to win. So far, we could make games for developing "loudness", "intelligibility", "turn-taking" etc. We tested our games with a good number of participants in Bangladesh and got encouraging results. I am now conducting different surveys, making newer games to develop other speech skills for the autistic children. We are also making a class-room software which enables autistic children to attend classes with neuro-typical (normal) students in the same classroom. 

This research work is being done in collaboration with a PhD student of the Affective Computing Group of MIT Media Lab. This project is supported by Autism Welfare Foundation (AWF) and One Laptop Per Child (OLPC) project.

With the burgeoning growth of mobile-phone users in the third world countries, the necessity for location based systems is going higher. While the third generation mobile phones are thought to be the ideal platforms for various ubiquitous services, low cost mobile phones are being considered to be a way to help the poor rural people of the developing regions. The SMS-based services have a bright future in helping this big population who live under the poverty line. However, illiteracy very often compromise the scope of text-message based services. Hence, voice messaging and other options are getting popular in today's world. Mobile-phone based services are very often dependent of the digital map of a place. So, the first step for implementing an intelligent location based service for a region is to make a good digital map of that place. With a very similar mindset, I have launched the "MapBangladesh" project here in Bangladesh. I am being helped by International OpenStreetMap Foundation. The objective of this project is to make free and open maps using GPS units. Besides making beautiful maps, we also are designing a number of systems which can help people with location based services.

I was involved in setting up a bio-surveillance project in Bangladesh which was supervised by Professor Artur Dubrawski of the Auton Laboratory, Carnegie Mellon University. The main idea of that project was to deliver early alerts of epidemics based on the real-time data collected from different hospitals via SMS.


I worked on a number of optimization problems of Computational Geometry. Most of these works were continuation of my undergraduate thesis. I worked on optimizing the cutting cost (in term of area or length) of a geometric shape out of another. I could devise a number of algorithms for this. Most of my works on geometry were done with Prof. Masud Hasan who is an active researcher of this field. Our works on cutting polyhedron out of a sphere was the first algorithm that could cut a 3D objects using guillotine cuts. I also worked on Voronoi diagrams. I mapped a number of facility location problems to Voronoi games and determined the optimized solution for those.
