career path - How to stay active in research when my faculty job involves mostly teaching and administrative duties?

I recently completed a PhD in a research university in U.S. and came back to my home country in South America. I have a position as a faculty member in a state college. However, the position focuses on teaching and academic administration duties. Without a lab and funding, it has been very difficult to continue the research or even to continue a reciprocal correspondence with my research collaborators.

I was wondering if I can ask for suggestions about how to continue pursuing my career path as scientist.
