Travis Gagie

Travis Gagie is an Associate Professor in the Faculty of Computer Science at Dalhousie University, where he conducts research on compact data structures with applications in bioinformatics and computational genomics. He is currently teaching CSCI 6905: Compact Data Structures in Computational Genomics and is funded by an NSERC Discovery Grant (RGPIN-07185-2020). His work bridges algorithmic design with real-world challenges in genomic data representation and equitable healthcare.

His educational background includes:

• BSc in Cognitive Science from Queen's University (Canada)
• MSc in Computer Science from the University of Toronto
• Dr. rer. nat. in Genome Informatics from Bielefeld University (Germany)

Travis Gagie's research focuses on overcoming biases in genomic data analysis, particularly those arising from the use of a single reference genome. He investigates pan-genomic data structures such as variation graphs, founder sequences, and r-index to enable more inclusive and accurate genomic medicine. His work emphasizes scalable indexing methods for diverse populations and rare disease diagnosis, intersecting with ethical considerations in precision medicine. He has collaborated with researchers globally and taught courses in Spain and Chile.

The recent articles in his portfolio reflect a strong trend in developing and analyzing data structures for pan-genomic applications. These include variation graphs (vg, minigraph), compact indexes (r-index, MONI/PHONI), and alignment tools (Giraffe, PLAST), all aimed at improving scalability, accuracy, and inclusivity in genomics. His research integrates theoretical computer science with practical bioinformatics challenges, particularly in the context of human and microbial pan-genomes.

Although no formal scientific awards are mentioned in the provided texts, his active research program, teaching responsibilities, and grant funding indicate strong academic recognition and productivity.

Travis Gagie has previously served as a research assistant at the Italian National Research Council and the University of Eastern Piedmont, completed postdoctoral work at the University of Chile, Aalto University, and the University of Helsinki, and was an associate professor at Diego Portales University. He has also been a visiting researcher at Illumina, the University of A Coruña, and the Czech Technical University. While he is not currently seeking graduate students or interns, he maintains an open-door policy for academic discussion via Webex and email. He emphasizes the importance of ethical considerations in genomics, particularly in relation to Indigenous populations and equitable healthcare access.

He is actively involved in academic outreach, recommending seminars such as the CGEM series on equity in genomic healthcare and promoting workshops like Data Structures in Bioinformatics (DSB '21). He supports student learning through video lectures, assignments, and collaborative discussions, often integrating real-world case studies like the Silent Genomes Project to contextualize technical work.
