Summer Scholar 2012

Omobolanle Ajenifuja is a rising junior at Lindblom Math and Science Academy.During this school year, she was in a colliquim class where the students worked with Meghan Vincent to answer the question 'Does Chicago spend more money in certian wards than others?". She has continued working to collect the data and she worked with Meghan Vincent collecting and analyzing data. 

"This summer has shown me how research is conducted. It has taught me a lot about energy and possible consqences about what we are doing to the environment. As result of this summer, my interest in field of energy and energy policy has grown.

Research Scientist

Computation Institute

University of Chicago

Areas of Expertise:

  • Algorithms for large singular linear systems
  • Applied and computational mathematics
  • Industrial-grade software engineering

Choi currently focuses on computational issues and software design for solving scientific problems related to climate change and economic policies. She works on OSCEF, an open-source software framework and toolbox whose core is for formulating and solving large-scale computable general equilibrium (CGE) models, which are widely used in computational economics and climate policy analyses.  

In 2012, Choi was awarded the SIAM Activity Group on Linear Algebra (SIAG/LA) Prize for the paper based on her doctoral dissertation, "MINRES-QLP: A Krylov Subspace Method for Indefinite or Singular Symmetric Systems," SIAM Journal on Scientific Computing, 33:1810-1836, 2011. The prize is awarded every three years by the Society for Industrial and Applied Mathematics (SIAM) and is considered one of the most prestigious prizes of its kind in the field. In 2007, Choi received Special Congressional Recognition from the U.S. House of Representatives for outstanding public service.

Choi received her PhD in Computational and Mathematical Engineering from the Stanford University. She was a Senior Member of Technical Staff with Oracle before joining the University of Chicago with a joint appointment in the Argonne National Laboratory.  Choi is a member of the SIAM, the Association for Women in Mathematics (AWM), and the Hong Kong Mathematical Society (HKMS).

Don Fullerton

Gutgsell Professor, Department of Finance and Institute of Government and Public Affairs

University of Illinois, Urbana-Champaign

Areas of Expertise:

  • Environmental and energy economics and policy analysis
  • Public economics and taxation
  • Distributional effects of taxes, social security, and regulations

Fullerton’s early research in public economics focused on computable general equilibrium models of taxation, marginal effective tax rates, the marginal cost of public funds, and distributional effects of taxes on a lifetime basis. His more recent research includes the distributional effects of social security. In environmental and energy economics, Fullerton works on household disposal of garbage and recycling, policies for green design, vehicle emission control policies, carbon taxes, and other policies in the energy sector where direct environmental taxes are not feasible.

Don Fullerton received a BA from Cornell in 1974 and a PhD in Economics from UC Berkeley in 1978. He taught at Princeton University (1978-84), the University of Virginia (1984-91), Carnegie Mellon University (1991-94) and the University of Texas (1994-2008), before joining the University of Illinois in 2008. From 1985 to 1987, he served in the U.S. Treasury Department as Deputy Assistant Secretary for Tax Analysis.

Kenneth L. Judd

/

 Areas of Expertise:

  • Economics of taxation
  • Imperfect competition
  • Mathematical economics

Judd's current research focuses on developing computational methods for economic modeling and applying them to tax policy, antitrust issues, macroeconomics, and policies related to climate change. He is currently the director of the Initiative for Computational Economics at the University of Chicago, and a member of the Natioanl Academies Board on Mathematical Sciences and Applications.

He was coeditor of the RAND Journal of Economics (1988–95) and the Journal of Economic Dynamics and Control (2002–2006), and associate editor of the Journal of Public Economics (1988–97). Judd is a fellow of the Econometric Society and served as a member of the Economics Panel of the National Science Foundation (1986–88).
