We need a new international project. This is important for mobility of students, postdoc and professors.

30. GOALS & PERSPECTIVES FOR 2014 1. Continue our activities in MEDIPIX with new MSc student in collaboration with the bio-engineering department and other Colombian universities. 2.Continue our participation in the RPCs 3.Maintain the participation of our engineers in the CMS computing M&O A program. 4.Finish thesis of Juan Pablo Gómez on stop search with t-tbar background reduction with matrix elements method. 5. Advance with thesis of Luisa Chaparro on Higgs dalitz decay. 6.Start thesis of Andres Cabrera on SUSY VBF with muons in final state  This thesis will help to pave the way for our collaboration with Texas A&M and Vanderbilt. 7.Start our contribution to the GEM project.  Collaboration with Texas A&M and Vanderbilt seems positive. 8. We have also interest in participating in a SUSY phenomenology- experimental project in collaboration with Texas A&M and Vanderbilt  Possibly with new PhD student Felipe Gonzalez. 9. Need to write some inernal notes for the work done by our group, including service work and theses of our students. 10. Need to find new external sources to finance our activities, specially mobility. January 8th 201430C. Avila, UNIANDES
