I was on sabbatical leave to MIT in 2023. Here is one of the several groups I was (and still am) working with.

I lead the Theoretical and Experimental Algorithmics (TEA) Group where we concentrate on both algorithm design and algorithm engineering. I have a joint appointment with the Institute for Advanced Computational Science (IACS).

I received my Ph.D. from the Department of Computer Sciences, UT Austin, working with Professor Vijaya Ramachandran, and defending this: "Cache-efficient Algorithms and Data Structures: Theory and Experimental Evaluation".

Prior to joining SBU, I was in Boston working with Professor Sandor Vajda's Structural Bioinformatics Group at Boston University, and Professor Charles Leiserson's SuperTech Research Group at MIT. Before moving to Boston, I was a postdoctoral fellow at the Computational Visualization Center (CVC), Institute for Computational Engineering & Sciences (ICES), University of Texas at Austin. I worked with Professor Chandrajit Bajaj. (Link to an old page of mine that still exists: MIT)

I am a Bachelor of Science in Computer Science & Engineering from Bangladesh University of Engineering & Technology. My undergraduate supervisor was Professor Mohammad Kaykobad to whom I am infinitely indebted.

Research Interests
      ¤ Design and analysis of algorithms and data structures for combinatorial problems, especially,
      - Algorithms for massive datasets: external-memory, cache-oblivious, streaming, parallel, etc.
      - Algorithms for multicore computing.
      - Graph algorithms: static and dynamic, exact and approximate, etc.
      ¤ Computational Biology and Bioinformatics
      - structure-based drug design, protein-protein docking, protein flexibility, energetics, sequence alignment, etc.
      ¤ Computer-aided Algorithm Design.
      ¤ Experimental algorithmics.
