Vaibhav Krishna

Vaibhav Krishna is a Postdoctoral Associate in the Department of Social and Behavioral Sciences at the Yale School of Public Health, where his research bridges information systems, data science, and public health challenges. His work focuses on sustainable agriculture optimization, crisis informatics, and knowledge-sharing dynamics in digital communities.

Education:

• PhD in Information Systems from ETH Zurich (2022)
• MS in Statistics from ETH Zurich (2017)
• BTech in Material Science from Indian Institute of Technology Bombay (2009)

Dr. Krishna's research integrates advanced computational methods to address complex public health problems. He develops quantitative frameworks for sustainable food systems that balance environmental, nutritional, and economic constraints, with specific applications in India. His crisis informatics work analyzes real-time sensemaking during pandemics using language models, while his social computing research examines motivation dynamics in community question-answering platforms through graph-based recommendation systems.

His publication record reveals three dominant research trajectories: sustainable agriculture optimization (40% of recent work), crisis-informed knowledge systems (35%), and machine learning for social computing (25%). Methodologically, he combines optimization algorithms, temporal graph analysis, and natural language processing to tackle sparse data challenges in real-world settings. His interdisciplinary approach consistently translates technical innovations into actionable public health insights.
