Deshan Perera

About Me

My name is Deshan Perera. I am currently a Ph.D. (specialization in Bioinformatics) Candidate in the Department of Biochemistry and Molecular Biology, Cumming School of Medicine at the University of Calgary, Canada. My main research focus is on within-host evolution and pathogen genomics. My areas of expertise lie in understanding evolutionary dynamics within organisms and developing high-performance computational solutions to analyze these problems.

My academic journey began with the completion of a Bachelor of Science (B.Sc. Hons) degree with a specialization in Biology from the Faculty of Applied Sciences at the University of Sri Jayewardenepura, Sri Lanka where I graduated with a First Class. During these four years, I trained in mainly wet lab sciences and explored the genetic and physiological factors of organisms. My undergraduate thesis explored the molecular cloning of the Cystatin C (CST3) protein from Oplegnathus fasciatus as well as an in-detail in-silico study of its protein-protein interactions and viability as a cysteine protease inhibitor via protein docking and gene-gene interaction mapping. I was supervised by Prof. Dinithi Peiris.

After the successful completion of my undergraduate studies, I shifted from wet-lab biology to dry-lab Bioinformatics for my Ph.D. My supervisor is Prof. Quan Long (Long Lab) and we investigate evolutionary dynamics experienced by organisms with focuses on pathogen genomics and neutrality. 

Research Interests

My current goal is to explore the development of computational tools for solving genetic problems. Ideally, I design and develop accelerated and scalable software solutions. A major drawback the expanding genetic data faces is the inability to process these vast repositories. Therefore, I wish to develop software solutions that are not only capable of rapid processing times via the use of parallel processing technologies such as the GPU, CPU, and SSD but also make these software resource efficient so that they can be scaled to adapt to the dataset being processed and the hardware resources at hand.

Expertise

My areas of expertise are from both dry lab (Ph.D. (Bioinformatics)) and wet lab (B.Sc. (Hons) Biology) sciences.
