Sessional LecturerBioinformatics Scientist
I'm a biologist from Brazil 🇧🇷, and Master of Science from the Genome Science and Technology (GSAT) program.
I arrived in Canada 🇨🇦 in August 2020 and embarked on a journey to become a skillful scientist and member of the academic ecosphere of Vancouver. I bring collegiality, creativity, and a strong work ethic to my research and teaching. I am passionate about the intersection of science and education, and I strive to make a positive impact in both fields.
A few professional passions can describe me:
Teaching, where I have been a sessional lecturer for two courses at UBC: Thinking Like a Life Scientist (BIOL 180) and First-year Seminar in Science (SCIE 113); I acted as a Teaching Assistant (TA) and TA coordinator for numerous courses across UBC's Biology Program, Biomedical Engineering (BMEG), and Physics & Astronomy (PHYS) departments.
Research, where I have been involved in various research projects, more recently with the genome annotation of a high-quality assembly of the ctenophore Mnemiopsis leidyi at the Plotkin lab;
Mentoring, where I have had the opportunity to mentor undergraduate and graduate students, as well as young adults and adults and help them develop their skills;
Outreach, where I have been involved in various outreach activities to promote science education, including my science communication blog, "On the Trails of Reason" (language: Portuguese-Brazil).
Interests (Bioinformatics) : Evolutionary Biology, Genomics, Efficient Processing of Big Data, and Genomic Data Visualization.
Interests (Philosophy of Science & Education) : Critical Thinking for Science and Education, Fostering of Epistemic Virtues, Nature of Science, and Science Communication Strategies.

[Feature Article] When we Become the Seekers
Gabriel Dall'Alba*, Guilherme Brambatti Guzzo* (* equal contribution)
Free Inquiry 2025
In this article, we explore the fascinating case of Leon Festinger's "When we Become the Seekers". It serves as a scaffold to reason philosophically about our beliefs and how to navigate them. We dive deeply into the story of the so-called Seekers, and tackle ideas such as "A belief is a part of me, so what?". This article was featured and also is available in Audio edition.

[M.Sc. Thesis] Toward a comprehensive understanding of early metazoans : reannotation for enhanced completeness of the ctenophore Mnemiopsis leidyi genome
Gabriel Dall'Alba
University of British Columbia 2024
The genome of the ctenophore Mnemiopsis leidyi, a marine species of gelatinous zooplankton, was recently re-analyzed to obtain a more complete and gap-free DNA sequence. This updated survey uncovered an additional 50 million base pairs, expanding the known genetic material of this organism. Using state-of-the-art methods, we systematically labeled and interpreted different regions of the genome. We explored the repetitive sequences within the genome, providing insights into the evolutionary trajectory of ctenophore genomes. In addition, we successfully identified previously missing genes and analyzed complex regions of the genome that are traditionally difficult to resolve. Finally, through genomic comparative studies, the present M. leidyi assembly and annotation results are consistent with previous research placing the ctenophore as the earliest branching lineage in animal evolution.

[Feature Article] Science Does Not Have All the Answers—and This Is Not a Problem
Gabriel Dall'Alba*, Guilherme Brambatti Guzzo* (* equal contribution)
Skeptical Inquirer 2024
In this article, we explore the philosophical framework that claiming "science does not have all the answers" as an argument against the validity of a scientific idea is misleading. Instead, we argue that it is part of the ethos of science to not have all the answers.

[Original Research Paper] The importance of qualified communication of ideas on science education
Gabriel Dall'Alba*, Guilherme Brambatti Guzzo* (* equal contribution)
Revista Interdisciplinar de CiĂŞncia Aplicada 2022
Science education involves several features that are beyond the so-called products of science: ideas, theories, hypotheses, laws, and results. Any education that aims the full comprehension of science as a human endeavor should incorporate epistemic qualities of the nature of science in the teaching of scientific content. One strategy for promoting the transmission of these features is the formal employment of qualification of ideas through guarding terms. Here, we discuss some of the epistemic features of science and their connection to the qualification of ideas in classrooms: epistemic fallibilism, open-mindedness, and the ongoing review process. We argue that the employment of terms and sentences that better reveal the strength of the existing evidence for a given idea can better reflect the presence of those science features on the scientific process. The substitution of terms such as “proven” or “it was proven that” by “probable” or “evidence suggests that” can better describe the epistemic status of scientific ideas, which are not fixed between true or false, but contained in a complex spectrum of likelihood. Strengthening science education with emphasis on the understanding of the nature of science can help to fix modern problems, such as the increasing distrust in science and in their products, such as vaccines and pharmaceutical drugs, as well as helping to reasonably dose the strength of the belief on those ideas.
