SUMMARY
Currently, Cristina Alejandra Villamar Ayala is Assistant Professor in Sanitation Engineering at the Department of Civil Engineering, University of Santiago, Chile. In addition, she has worked as assistant professor at the Escuela Politécnica Nacional, Ecuador (2016-2017) and collaborated as researcher at the Universidad de Concepción, Chile (2009-2014).
C.A. Villamar has collaborated within national researcher’s projects (FONDECYT-2004-1040987, INNOVA BIO BIO 07-PC S1-198) and international projects (PIE-BIOGAS-2016, PIMI-1406) related with characterization, treatment and revaluation of wastewater and waste. During her postdoctoral position in the Centro de Recursos Hídricos para la Agricultura y Minería (CRHIAM-CONICYT/FONDAP/15130015) collaborated in researches focused on revaluation of livestock wastewater/waste. Her research experience has generated 13 WOS publications, 14 publications with editorial committee, 3 book chapters and attendance at more than 20 congresses and/or scientific events at national/international level.
