This winter, head to Yellowstone National Park for a very special 7-day wildlife expedition. Amidst crisp air, bare trees, frosted earth, and brilliant thermal features of Yellowstone National Park, the wildlife viewing in winter is better than any other time of year. The elements of nature are in full sway and its wild inhabitants, close-knit family groups of wolves, are on the move: hunting, searching for warmth, and surviving. Look for the elusive predators while traveling in safari vehicles and interpreting tell-tale signs with the help of an Orbridge Expedition Leader. Learn historic and ecological aspects of the successful reintroduction of the gray wolf to the Yellowstone region. Don’t miss this extraordinary experience in the “Serengeti of North America.”

Program Highlights:

  • Immerse yourself in the unspoiled natural beauty, diverse wildlife, and dramatic tales of this unique ecosystem during this exclusive small group expedition to Yellowstone in winter
  • Scout for wolves from the warmth of a heated vehicle—Yellowstone is considered one of the best wolf-watching habitats in the country
  • Joined by an expert Orbridge Expedition Leader and professional naturalist guides, learn informed perspectives and first-person accounts of the wolves’ setbacks, survival, and victories
  • Keep binoculars close at hand: this site is ranged by resident bison, elk, pronghorn, bighorn sheep, moose, and other wildlife
  • Experience Yellowstone in its winter incarnation: a world with frozen “geyser rain,” ghost trees with a frosty glaze, surprising winter wildflowers, and dynamic geothermal features set in snow and ice

Dorothy Wallace

Dr. Wallace is a professional mathematician with a dedication to improving mathematics and quantitative education at all levels. She possesses an unusual breadth of experience: research, teaching, research supervision, curriculum innovation and development, professional development, textbook publication, and overall promotion of new curriculum and pedagogy. Dr. Wallace does not tweet or post, but her thoughts on the educational system and on specific teaching issues are available in her regular column for the open access journal Numeracy, “Parts of the Whole.”

With over 120 publications in pure and applied mathematics and mathematics education, Dr. Wallace has supervised 10 PhD students in mathematics and two master’s degree students in Liberal Studies, as well as over 50 undergraduate research projects. She has received several teaching awards: The CASE (Carnegie Foundation for the Advancement of Teaching and the Council for Advancement and Support of Education) New Hampshire Professor of the Year Award (2000), the Dartmouth Graduate Mentoring Award (2005), and the Dean’s award for mentoring undergraduate research (2017). She has served as a consultant on numerous education projects nationally.

Her first area of research was number theory, perhaps the oldest type of pure mathematics. During this period, she investigated a class of functions called “automorphic forms” that code important information about the distributions of certain kinds of numbers.  She used her expertise in number theory to contribute the understanding of error correcting codes, dynamical systems, discrete feedback systems, new ways to factor integer matrices, and other applied areas.  At the interface of pure and applied mathematics she made a series of contributions to the understanding of observability properties of dynamical systems.     

Around 2008 she became interested in mathematical biology largely due to a course she developed for undergraduates. Mathematical models have the ability to embody assumptions made by biologists in order to produce a quantitative consequence that either does or does not fit observations.  A good model will reflect reality even in very specific settings.  Producing such models is something she continues to enjoy.  She has numerous professional publications in mathematical oncology, the epidemiology of vector borne diseases such as malaria and Lyme disease, and the phenomenon of phenotype plasticity. Nearly all of her papers in mathematical biology since 2010 have one or more coauthors who were Dartmouth undergraduates.

On this trip, she will share her mathematical insights into the population dynamics of Yellowstone Park, which include the interactions of wolves, elk, beavers, and aspen.
