The Division of Physical Sciences combines innovative, interdisciplinary research with a commitment to training the next generation of researchers and informed citizens. Some of the projects in the division’s three departments—chemistry and biochemistry, mathematics, and physics—require journeying to the ends of the earth. To understand the chemistry and global transport of atmospheric particulates, physical sciences dean Mark Thiemens and his team have collected ice samples from the South Pole and the highest point on the Greenland ice sheet.
A different kind of Incredible Voyage is the use of nanotechnology to mark and starve tumors. UCSD chemists and physicists have created microscopic nanoparticles of iron oxide that show up brightly on MRI scans—making a tumor easier to detect. The nanoparticles block about 20 percent of the blood vessels that feed the tumor. Initial studies were performed on mice, but researchers hope the technique can be used to treat cancer in humans.
Retaining students in the science and mathematics pipeline is a priority for the division and for the local community. Spring 2007 saw the inaugural Greater San Diego High School Honors Statistics contest, as well as the fiftieth annual High School Honors Math contest. UCSD mathematicians organized both competitions in collaboration with the Greater San Diego Math Council.
Contests motivate young minds—and so do great teachers. Fiscal year 2006–2007 marked the launch of new math and science education minors at UCSD, in conjunction with the California Teach program. These minors encourage math and science undergraduates to consider careers in K–12 teaching.
In June, the interdisciplinary environmental systems program graduated its 100th student. The degree prepares undergraduates for community work on sustainability initiatives, conservation management, and environmental monitoring.
