Hi, welcome to my homepage. I am currently a Member of Research Staff at the Fujitsu Laboratories of America. I received my Ph.D. degree in Spring 2016 from the Department of Electrical and Computer Engineering at The University of Texas at Austin, USA. I was advised by Prof. Dewayne Perry, and often co-advised by Prof. Sarfraz Khurshid. I obtained my Masters degree in Computer Science from Department of Computer Science at the University of Saskatchewan, Canada and Bachelor degree in Computer Science and Engineering from the Khulna University, Bangladesh.My primary interest is in Software Engineering. In the twenty first century, software has become one of the most important products and industries in the world. However, software development is expensive. With the advancement of technology, the cost of hardware has been consistently decreased, while the cost of software, in many instances, has increased. One of the main reasons for the high cost of software is that software development is still human dependent - as opposed to hardware development that is now largely driven by mechanized industry. Therefore, I aim to carry out research related to increasing programmer productivity. To this end, I analyze large-scale software repositories to learn interesting phenomena in software development and maintenance, and leverage that data driven knowledge to design and develop novel techniques to help automating bug fixing process. More specifically, I am interested in developing tools for automatic debugging, automatic testing, and automatic program repair.
