Computer Science and Engineering

Hasindu Gamaarachchi focuses on the design, development and optimisation of bioinformatics software and hardware for real-time nanopore sequencing data analysis; and, prototyping novel domain-specific computer systems for efficient genomics data analysis. He has around ten years of experience in embedded computing systems, computer architecture, general-purpose computing with the use of a Graphics Processing Unit (GPU), high-performance computing and low-level system programming, which he leverages for the architecture-aware design of efficient computational systems for bioinformatics. Examples of his recent work include: a novel domain-specific file format for efficient nanopore data processing (); GPU-accelerated adaptive banded event alignment algorithm which is a core component in nanopore data analysis (); memory optimisation of nanopore sequence alignment using partitioned indexes (); and, optimisation of de Bruijn graphs using cache-friendly data structures in next-generation variant calling ().Ìý

Since 2023, Hasindu has been a lecturer at the School of Computer Science and Engineering, Âé¶¹Éçmadou Sydney.Ìý He is also a in the . From 2020 to 2022, he worked as a Genomics Computing Research Scientist at Garvan Institute of Medical Research. Hasindu completed his PhD in Computer Science and Engineering at Âé¶¹Éçmadou Sydney in 2020.ÌýHis PhD research has won multiple awards including .ÌýHe has served as a lecturer at the Department of Computer Engineering and a resource person at NVIDIA research centre at the University of Peradeniya.ÌýHe completed his bachelor’s degree with first-class honours in Computer Engineering from the University of Peradeniya, Sri Lanka in 2015, where he received the award for best performance in Engineering.
