Matz Haugen

Postdoctoral Scholar, Department of Statistics

University of Chicago

I currently do research on extreme event characterization, modeling and forecasting using geological data like climate models and observations. For example, are days of extreme temperatures getting more frequent? Or is the annual temperature profile more variable with the current post-industrial climate forcings compared to the pre-industrial era? To answer these questions I look at climate model output, e.g. Global Circulation Models, using different starting conditions and see how their behavior changes statistically.

Related to this is also the desire to incorporate a more statistical framework with the current deterministic climate models. This involves for example adaptive grid sizes and time steps dependent on desired spatio-temporal resolution.

Research Scientist, Computation Institute, University of Chicago

Areas of Expertise:

  • Analysis and prediction of nonlinear systems
  • Data Assimilation
  • Parameter estimation
  • Forecast interpretation and evaluation

Hailiang's research ranges from the advancement of the theory of nonlinear dynamical systems to the application of these insights in the context of large-scale numerical models including weather and climate. He is particularly interested in advancing the understanding of predictability in the context of those models, and better understanding the dynamics, analysis, and interpretation (for decision support) of climate models in general. His previous research work includes parameter estimation via examining the dynamical consistency of the model and via probabilistic skill score; advancing pseudo-orbit data assimilation approach for state estimation; evaluating probabilistic skill in real world ensemble forecasts, and forecast interpretation using sustainable odds. 

Hailiang received his PhD in statistics from the London School of Economics and Political Science (LSE) in 2009.

Lars Peter Hansen

Co-PI, RDCEP (2010 - 2015)

Research Director, Becker Friedman Institute

David Rockefeller Distinguished Service Professor

Department of Economics, University of Chicago

 

Areas of Expertise:

  • Methodology: Econometrics
  • Economics: Asset Pricing

Hansen is a recipient of the 2013 Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel for his early research.  Hansen shares this honor with Eugene Fama and Robert Shiller.

Hansen's work explores formal implications of dynamic economic models in which decision makers face uncertain environments. The main theme of his research has been to devise and apply econometric methods that are consistent with the probabilistic framework of the economic models under investigation. His work has implications for consumption, savings investment, and asset pricing. 

Hansen's early research in econometrics was aimed at developing time series statistical methods to investigate one part of an economic model without having to fully specify and estimate all of the model ingredients. The applications he explored with several coauthors included systems that are rich enough to support models of asset valuation and to identify and clarify empirical puzzles, where real-world financial and economic data were at odds with prevailing academic models.

He continues to explore, analyze, and interpret implications of dynamic economic models in environments with uncertainty from a time-series perspective. His recent research explores ways to quantify intertemporal risk-return tradeoffs and ways to model economic behavior when decision makers are uncertain about how to forecast future economic events.

Hansen is a fellow of the National Academy of Sciences and the American Finance Association. He is also a member of the American Academy of Arts and Sciences and past president of the Econometric Society. Hansen is a former John Simon Guggenheim Memorial Foundation Fellow and Sloan Foundation Fellow.

Hansen won the 2010 BBVA Foundation Frontiers of Knowledge Award in the Economics, Finance and Management "for making fundamental contributions to our understanding of how economic actors cope with risky and changing environments." In 2008, Hansen was awarded the CME Group-MSRI Prize in Innovative Quantitative Applications. This award is designed to recognize individuals or groups who contribute original concepts and innovation in the use of mathematical, statistical or computational methods for the study of the behavior of markets, and more broadly of economics. Hansen is one of two scholars to receive the prestigious 2006 Nemmers Prizes in economics and mathematics, believed to be the largest monetary awards in the United States for outstanding achievements in those two disciplines.
