Market Design Team

Al Roth

  • Stanford University, PhD
  • 2012 Nobel Laureate
  • Stanford University

Al is the Craig and Susan McCaw Professor of Economics at Stanford University and the George Gund Professor Emeritus of Economics and Business Administration at Harvard.

Al shared the 2012 Nobel memorial prize in Economics, ‘for the theory of stable allocations and the practice of market design.’ His work is in game theory, experimental economics, and market design.

He directed the redesign of the National Resident Matching Program, through which most American doctors find their first employment as residents at American hospitals. He has also helped in the reorganisation of the market for more senior physicians, as they pursue sub-specialty training and in other labour markets. He helped design elements of the market for new Ph.D. economists.

Al helped design the high school matching systems used in New York City, and the school choice systems for public and charter schools in other large American cities. He has helped in the design and implementation of kidney exchange, which allows incompatible patient-donor pairs to find compatible kidneys for transplantation.

He is a Fellow of the American Academy of Arts and Sciences, and a member of the National Academy of Sciences.

David Malec

  • University of Wisconsin, PhD

David is a member of the Market Design Engineering team at Tremor. His role involves all aspects of the market design process, from initial design to practical implementation. Challenges include understanding and addressing incentive issues arising in specific markets; formulating and tuning market designs as mathematical optimization problems; and implementing these formulations as practical, working market platforms. In market design small decisions can have high impact, making a holistic approach that considers all of these issues critical to creating a market that successfully meets the particular needs of buyers and sellers within a given domain. In his role as Market Design Engineer, David focuses on ensuring that all parts of the market design process come together to create a platform that provides the maximum possible value to participants.

In addition to his work with Tremor, David Malec is also a Principal of Cramton Associates LLC and a post-doc in the Economics Department at the University of Maryland. His academic research focuses on topics at the interface between the fields of computer science and economics, and how complex economic settings can be approached algorithmically. He is particularly interested in how algorithmic techniques and insights can be applied in practical economic settings, and how this can be used to create markets and auctions for environments that would otherwise be intractable. He received his B.A. in Computer Science and Mathematics from Lake Forest College in 2007, and his Ph.D. in Computer Science from the University of Wisconsin, Madison in 2014, and his work has appeared in top conferences in algorithmic game theory and theoretical computer science.

Ben Lubin

  • Harvard University, PhD, Computer Science
  • BBN Technologies

After receiving his Bachelor’s degree in Computer Science from Harvard University, Ben joined BBN Technologies, the research and development firm where the first internet routers were developed, working on advanced multi-agent modeling, scheduling and logistics systems. After six years in industry, he returned to Harvard University to pursue a Ph.D. at the intersection of computer science, game theory and economics. Upon graduation he joined Boston University’s Questrom School of Business as an Assistant Professor in the Information Systems department, an affiliation he maintains in addition to his work for Tremor. Dr. Lubin’s research is in three primary areas: (1) mechanism design, especially of combinatorial auctions and exchanges, mechanisms that support efficient reallocation of goods when participants have complex preferences regarding bundles of items, (2) applications of machine learning techniques to mechanism design, especially for pricing and to facilitate preference elicitation, (3) the use of spectral graph theory and machine learning to advance the analysis of social networks, especially in healthcare settings. Dr. Lubin is a recipient of the Siebel Fellowship and a Yahoo Key Technical Challenge award. Portions of his academic research are funded by the NSF, the NIHCM, and the Veterans Administration.
