Jun 2023 - Dec 2023 (7 months)

As a Research Assistant & Researcher, I investigated and constructed polarization measures for social networks, accelerating analysis by 2.3x. I extended algorithms to quantify polarization trends, identifying significant behavioral patterns, and produced insights correlating real-world dynamics with simplified bias-based models. My work involved comprehending structures and cases when dispersion and polarization trends occur, implementing high data structures to simulate real-world cases, and utilizing sentiment analysis to adapt to these scenarios. I deployed advanced algorithms and numerical methods to approximate bias while working with large volumes of data from synthetic and real networks to apply metrics and algorithms for analyzing
