Thomas Zurbuchen, professor in the Department of Atmospheric, Oceanic and Space Science, testifies before a hearing of the Aerospace States Association in Washington, D.C. Zurbuchen and others discussed problems facing academic institutions because of federal rules that restrict access to space and other technologies for foreign nationals at U.S. universities. He told officials that these restrictions have reduced the number of foreign students and researchers participating in space science at U-M and urged the association to work with agencies and Congress to find better ways to protect sensitive American technology without inhibiting basic research.
