Ensuring transparency in the recruitment and talent acquisition process is essential. However, the current utilization of automated decision systems has proven to be disadvantageous for recruiters. This endeavor represents an initial effort to establish contextual transparency in online recruiting, with a specific emphasis on promoting candidate diversity and highlighting transferrable skills.
I am a PhD candidate in Data Science, with a background in Mathematics and Statistics. My research interest lies in the intersection of human-centered AI and information visualization. Currently, I am working on designing visual analytic interfaces for ranking interpretation on high-stake decision-making (e.g., student course evaluation, AI hiring practice); adapting Learning-to-rank for fairness, accountability, and transparency; adversarial attacks and detection on explainable AI methods; information-seeking in crisis.
Projects & Publications
Ranking is a socio-technical artifact that humans interact with daily. This work is an effort to develop principled protocols to understand the existing public rankings (e.g., college rankings), domain-specific rankings (e.g., loan applicant rankings), and rankings that are machine-generated (e.g., social media feed rankings.). Given the spate of new legislations on algorithmic accountability, it is imperative that researchers from social science, human-computer interaction, and data science work in unison to demystify how rankings are produced, who has agency to change them, and what metrics of socio-technical impact one must use for informing the context of use.
