“…The lab serves as the site in which students hone and apply specialized knowledge and skills, following the prevailing norms and values of their chosen scientific disciplines (Hunter et al, 2007;Holley, 2011;Szelényi et al, 2016). Students' participation in labs defines and shapes their emerging identities as scientists (Malone and Barabino, 2009;Lane et al, 2019). Additionally, lab placement typically defines the nature and scope of students' doctoral experiences by allowing them access to developmental networks of PIs, other faculty members, postdoctoral fellows, peers, and program administrators (Sweitzer, 2009;Ynalvez et al, 2017;Griffin et al, 2018).…”
