<p class="MsoNormal"><span style="font-family:"Times New Roman"">The Department of Geology and Environmental Geosciences at Northern Illinois University has an opening for a graduate research assistantship starting August 2014. This position is fully funded for 2 years.</span></p>
<p class="MsoNormal"><span style="font-family:"Times New Roman"">The graduate student (MS or PhD) will be conducting research on silicon isotope variations in diatom frustules and other biogenic silica. Specific research projects include: 1) developing new techniques for conducting simultaneous silicon (δ<sup>30</sup>Si) and oxygen (δ<sup>18</sup>O) isotope analyses of biogenic silica on an isotope ratio mass spectrometer (Thermo Scientific MAT 253) using laser fluorination, 2) conducting laboratory experiments to constrain changes in δ<sup>18</sup>O and δ<sup>30</sup>Si values during growth and diagenesis in different types of biogenic silica, and 3)</span><span style="font-family:"Times New Roman""> constructing a record of silicon isotope variations in biogenic silica from a previously collected Antarctic marine sediment core to examine the linkages between silicic acid utilization and silicon/carbon cycle relationships.<u></u><u></u></span></p>
