Shortly after Castellanos got the job of rector, President Manuel Zelaya was removed from power in a coup. During a demonstration by University students, the police tired to stop the demonstration. The police pushed Castellanos down when she tried to stop them. During her time as rector, she had disagreements with SITRAUNAH, the union for the University's employees. She also received criticism because she fired 60 employees who protested at the university 2009. Castellanos oversaw the construction of a sports complex, an administrative building, and a university clinic. The university invested L1,500 million in the clinic.
