Sigma Xi Distinguished Lecturers, 2017–2018

Potential hosts should contact lecturers directly to book events. In making arrangements, hosts should be specific about dates, lecture topic, scope of the lecturer's visit and any special accommodations that may be called for.

Each lecturer has designated his or her topic(s) for three different types of audiences. Where more than one level is shown, the lecture can be adjusted to the needs of the audience:

  • P (Public)
    Aimed at presenting scientific issues of general concern to a public audience.
  • G (General)
    Intended for a normal Sigma Xi audience of both scientists and other scholars representing a broad range of disciplines.
  • S (Specialized)
    Aimed at scientists and students in fields that are closely related to that of the lecturer.

    Sally C. Seidel is the faculty member of the University of New Mexico's Collider Physics Group. Their primary goal is an improved understanding of heavy quark bound states. These studies increase the understanding of the strong force, one of the four fundamental forces of nature. They may also contribute to the discovery of physics beyond the Standard Model. This work requires that they collect and analyze data at the Large Hadron Collider and other experimental facilities. It also requires them to design, construct, and test state-of-the-art particle tracking detectors, interconnects, and electronics. The instrumentation may ultimately be incorporated into medical imaging or security verification systems that would benefit the greater society.

She has helped develop online information systems for renewable energy assessment, and environmental indicators to inform air quality policy and build capacity for environmental governance in countries around the world. She spent two years in the Philippines as a U.S. Peace Corps volunteer working on water and sanitation, and more recently spent two years in Saudi Arabia, leading a solar and wind resource monitoring project for Battelle in collaboration with the U.S. National Renewable Energy Laboratory. She previously served as the Co-Chair of the Climate and Energy Working Group for the Earth Science Information Partnership (ESIP). She has worked with groups in Russia, Ethiopia, Senegal, El Salvador, Costa Rica, Panama, and Thailand, among others, hosting trainings and public outreach sessions. She also has extensive experience leveraging satellite datasets within a geographic information system (GIS) to support decision-making. Ms. Zell has performed projects under contract to the U.S. Environmental Protection Agency (EPA), U.S. Agency for International Development (USAID), and National Aeronautics and Space Agency (NASA), among other clients.
