Synergistic Activities
1. Graduate Students: I have been a co-supervisor of a Ph.D. Students,
Jose' Francisco Salgado of the University of Michigan who made a study
of "The Distribution of Interstellar Electron Density Fluctuations",
receiving his degree in 2000.

2. I have supervised over 10 NSF REU students during recent years. I have
also organized "hands on" summer observing projects for the Arecibo
REU students.

3. Other Education Activities: I helped organize, lectured to, and ran
"hands on" experiments for the 2001, 2003 and 2005 and 2007 NAIC/NRAO
summer schools on "Single Dish Radio Astronomy".

4. I help installing and maintaining all VLBI related equipment at the
observatory, and provide user support for observations and data
reduction in the areas of VLBI and Single Dish spectral-line

5. Computer Program Development: I have developed many data reduction
routines in FORTRAN and within the IDL environment.
