TEACHING EXPERIENCE

• Advisor for a graduate student PhD thesis at the University of Massachusetts.
• Designed and taught two semesters of a freshman astronomy laboratory course (Ay101L) at the University of Arizona. I designed six new experiments, several of which were used by other teachers of the same course in subsequent semesters.
• At the University of Arizona, I advised and guided two undergraduate senior theses in the construction and use of a Student Radio Telescope, a 12-foot satellite dish that we refurbished for radio astronomy. In addition, I have had several undergraduate students working with me on instrumentation projects at the University of Arizona.
• As a college senior and chairman of the IEEE student branch, I taught several courses in programming languages for underclassmen.

SERVICE ACTIVITIES

• Co-organizer of an Astronomy Lunch talk at UMass. Astronomy Lunch Series
• Served as referee for Time Allocation Committees for FCRAO observing proposals.
• System administrator duties for a cluster of FCRAO linux machines, including the observatory server machine.
• Wrote data conversion programs for observer use at FCRAO.
• Official Open Source Developer for the Debian linux operating system Debian Web Site

COMPUTING EXPERIENCE

Programming Languages: FORTRAN, C, Perl, Pascal, BASIC, DCL, C shell, Tcl/Tk.

Operating Systems: Linux, Solaris, SunOS, HP-UX, ConvexOS, VMS, Win95/NT, DOS.

Astronomical Software: Gildas, SPA, Unipops, MIRIAD, AIPS, IRAF.
