What, Exactly, Is Surveillance Pricing?, Kaylina Stroud

McNair Summer Research Program

Surveillance pricing is a method of price discrimination in which firms use personal data to set individualized prices. While this practice is often criticized on grounds of privacy, unfairness, or exploitation, these objections do not fully explain what is morally objectionable about surveillance pricing. This paper examines surveillance pricing through the lenses of price discrimination, market competition, efficiency, exploitation, and deception. I argue that surveillance pricing is not inherently unethical merely because it results in different consumers paying different prices for the same product. Nor is it necessarily objectionable when it promotes mutually beneficial exchanges and efficient market outcomes. The …

Faculty, Staff and Students Publications

Therapeutic resistance remains a major challenge in cancer treatment, driven by compensatory signaling and stress response pathways that sustain tumor survival. Topoisomerase IIβ-binding protein 1 (TopBP1), a multifunctional scaffold protein with nine BRCT domains, integrates replication stress signaling with oncogenic networks and is frequently overexpressed in aggressive cancers. Its BRCT7/8 domains mediate critical interactions with E2F1, mutant p53, MIZ1, PLK1, and CIP2A, making TopBP1-BRCT7/8 an attractive therapeutic target. Using docking-guided screening and structure-activity relationship–driven optimization, we developed CS18 as a potent and selective BRCT7/8 inhibitor that disrupts oncogenic TopBP1 complexes without interfering with DNA replication. CS18 suppresses MYC transcriptional programs, …
