research

Throughout my academic career, I have worn many hats in various fields of application: renewable energy, earthquake engineering, seakeeping and stability in the Arctic, and now disaster science. Underpinning all of these applications are an appreciation of complex systems, sensitivity analysis, uncertainty quantification, and scientific communication (both written and visual)

Counterfactual framework for uncovering black swans

PI: Dr. David Lallemant, Dr. Susannna Jenkins. Nanyang Technological University. Sponsored by the National Research Foundation Singapore.

  • Develop a framework to apply downward counterfactual thought experiments to past events
  • Analyze Singapore-based case studies related to earthquakes, volcanoes, building collapses, and tropical storms
  • Hosted the Counterfactual Black Swans Workshop (August 26-27, 2019), a 28 person workshop to bring together hazard scientists, risk communication experts, engineers, and insurance consultants to apply our framework to a broader context. Read more from my blog post here, and workshop report here.

Monitoring ice accumulation for surface ships traveling in the Arctic

2014-2018

PI: Dr. Christopher J. Earls. Cornell University. Sponsored by the Office of Naval Research (ONR).

  • Develop stochastic inversion framework for monitoring evolving surface ship mass properties during Arctic operations
