 The GDSCN (Genomics Data Science Community Network) is a consortium of educators who aim to create a world where researchers, educators, and students from diverse backgrounds are able to fully participate in genomic data science research. You can find more information about its mission and initiatives [here](https://www.gdscn.org/home).

-One critical aspect of an undergraduate STEM education is hands-on research. Undergraduate research experiences enhance what students learn in the classroom as well as increase a student's interest in pursuing STEM careers [@Russell2007]. It can also lead to improved scientific reasoning and increased academic performance overall [@Buffalari2020]. However, many students at underresourced institutions like community colleges, Historically Black Colleges and Universities (HBCUs), tribal colleges and universities, and Hispanic-serving institutions have limited access to research opportunities compared to their cohorts at larger four-year colleges and R1 institutions. These students are also more likely to belong to groups that are already under-represented in STEM disciplines, particularly genomics and data science [@Canner2017; @GDSCN2022].
