This Research Topic is part of the Insights in Frontiers in Genetics series. Other titles in the series are: Genetics, Insights in Evolutionary and Population Genetics: 2022 Genetics, Insights in Livestock Genomics: 2022 Genetics, Insights in Epigenomics and Epigenetics: 2022 Genetics, Insights in Behavioral and Psychiatric Genetics: 2022 Genetics, Insights in Neurogenomics: 2022 Genetics, Insights in Genomic Assay Technology: 2022 Genetics, Insights in Genetics of Common and Rare Diseases: 2022 We are now entering the third decade of the 21st Century, and, especially in the last years, the achievements made by scientists have been exceptional, leading to major advancements in the fast-growing field of Genetics. Frontiers have organized a series of Research Topics to highlight the latest advancements in research across the field of Computational Genomics, with articles from the members of our accomplished Editorial Boards. This editorial initiative of particular relevance, led by Prof Richard Emes, Specialty Chief Editor of the Computational Genomics section, together with Dr. Pirooznia and Dr Zou, focused on new insights, novel developments, current challenges, latest discoveries, recent advances, and future perspectives in the field of Computational Genomics. The Research Topic solicits brief, forward-looking contributions from the editorial board members that describe the state of the art, outlining recent developments and major accomplishments that have been achieved and that need to occur to move the field forward. Authors are encouraged to identify the greatest challenges in the sub-disciplines, and how to address those challenges.
