 =='''Biography'''==
-I am a first-year student at Michigan Technological University, in the Materials Science and Engineering Department.  I have been a member of the [http://www.mse.mtu.edu/~pearce/Index.html MOST Research Group] for over a semester.  This position involves the research of the Molecular Beam Epitaxy (MBE) process to produce semiconductors of improved quality for application in increasing the efficiency of electronic devices.  Through my work, I have had active exposure to the design of experiments, and gained experience in surface analysis by SEM and AFM, sample analysis by X-ray diffraction, and the analysis of in situ crystal growth by RHEED.  This position also includes MBE system maintenance (coolant and vacuum system maintenance/operation, including turbomolecular pumps, a roughing pump, and ion pumps; mounting of MBE effusion cells, installing sensors).  I regularly operate the MBE (ISA RIBER MBE 32 system) system, and prepare samples for those experiments, which includes solvent cleaning and acid etching of substrates, as well as mounting them on sample holders.
