HARP is a 501(c)(3) nonprofit organization. Read below for our mission and purpose statements and to learn about our leadership team.

Our Vision

To advance the development of hyperloop technology

Our Mission

To promote the collaboration, research, funding, and knowledge sharing necessary for the development of high-speed tube transportation networks and standards around the world.


The Hyperloop Advanced Research Partnership (HARP) is the nexus for hyperloop information, research, and stakeholder collaboration. HARP was formed to help the hyperloop industry reach its potential of building a transportation system that is more efficient, sustainable, secure, connected, and resilient. Creation and operation of hyperloop technology involves diverse stakeholders – from many industry sectors to all levels of government (local, state, regional, and national), to university research groups and individuals. HARP provides a framework for stakeholders to gather, share ideas, innovate, and collaborate in ways that support both individual and collective efforts to grow hyperloop capabilities. HARP's focus is to:

  • Serve as a trusted independent agent and catalyst for information, research, and collaboration

  • Encourage research that facilitates development of efficient, sustainable, and resilient hyperloop transportation systems

  • Enlist members from industry sectors and local, state, regional, national governments

  • Leverage the benefits of public, private, academic partnerships to advance hyperloop development

  • Convene key stakeholders to support education, research, and public engagement

Scientist, technologist, expert in systems development and management of teams. National Center for Atmospheric Research (retired).


For more than two decades Dr. Cohn led research and development teams at the National Center for Atmospheric Research (NCAR), specializing in improving technology for complex measurements. His personal research experience includes topics such as aviation safety, cloud and precipitation processes, and turbulence. Under his leadership, teams conducted experiments on all continents, while developing instruments to improve hurricane forecasts, analyze airflows in mountainous terrain, and study atmosphere-ocean interactions. He serves on the World Meteorological Organization’s Commission for Instruments and Measurements of Observation, and leads the team creating the next International Cloud Atlas. He has organized national and international scientific conferences, including the International Symposium on Tropospheric Profiling, and the Symposium on Meteorological Observations and Instrumentation. While at McGill University, he commissioned the first boundary-layer wind profiler in Canada and expanded its capabilities for real-world applications. At the Massachusetts Institute of Technology (MIT), he adapted large radars intended for astronomy and satellite tracking to study high-altitude turbulence at aircraft flight levels. Dr. Cohn is the author of more than 45 peer-reviewed scientific papers, and has presented at more than 100 symposia, conferences, and workshops. His research and professional interests are focused on applying the best technology available to address meaningful and complex challenges.

Director, Cornell Program in Infrastructure Policy (CPIP). Professor, Department of Policy Analysis & Management, Cornell University.


Prof. Geddes is an Associate Professor in the Department of Policy Analysis and Management at Cornell University and a core faculty member of the Cornell Institute for Public Affairs (CIPA). He is a founding director of the Cornell Program in Infrastructure Policy, or CPIP and a Visiting Scholar at the American Enterprise Institute. Geddes is also a Research Fellow with the Mineta Transportation Institute at San Jose State University. His research focuses on policies toward the funding and financing of major infrastructure projects in the transportation and water sectors. His current professional activities focus on researching public policies toward the funding and financing of physical infrastructure, with an emphasis on the transportation, water and energy sectors. This includes innovative financing approaches such as public-private partnerships. Specific research topics include state-level public-private partnership enabling laws, new types of public-private partnerships designed to increase investment in infrastructure, life-cycle asset maintenance of infrastructure, and the state-level drivers of investment in transportation infrastructure. A main research focus is on private investment in the design, construction, financing, operation and renovation and construction of U.S. infrastructure through public-private partnerships, or PPPs. Specific concerns include life-cycle maintenance of infrastructure assets, the impact of state-level PPP enabling laws, and the effect of operation-and-maintenance road concessions on traffic safety. Geddes is also studying policies that have effectively attracted infrastructure investment in other countries. Additional interests include postal and delivery economics, and policies affecting governance in large, publicly traded corporations.
