Vidisha specializes in the intersection of machine learning, economic modeling, and public policy. At PWBM, she focuses on the demographic components of the organization’s microsimulation framework, with specific expertise in immigration policy and natality forecasting. Her recent research examines the implications of AI adoption for work and the economic impacts of U.S. visa policy changes. To support this work, she has led the development of several foundational datasets that enable the estimation and analysis of complex immigration flows.

Her previous work centers on using data to inform proactive decision-making. As a Data Science for Social Good Fellow at the University of Washington, she developed a machine learning pipeline to predict residential heating energy demand, helping guide decarbonization efforts in Alaska. Her research experience includes two years as a Research Associate at the Indian Statistical Institute, where she evaluated the impacts of clean energy use on indoor air pollution in rural India. At Carnegie Mellon, she worked on several policy projects, including predictive modeling to optimize mental health outreach and forecasting legislative outcomes to support strategic advocacy.

Projected Effects of the New (March 2026) H-1B Visa Lottery

We project that the new DHS H-1B selection rule, going into effect in March 2026, will shift the H-1B visa allocation toward higher-paid and higher-education foreign-born workers, but by less than alternative designs being debated. Based on data from the current random lottery in the last five years, we estimate that the new DHS rule will have no significant impact on wages of U.S.-born workers, including non-college, college-educated, and STEM workers. Any reduction in competition from fewer STEM H-1Bs is offset by a reduction in productivity growth.
