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 observations.

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