About the Author

Erika Jimena Espinosa-Ortiz was born in Mexico City in 1984.  She received her Bachelor's Science degree, summa cum laude, in Environmental Engineering from the Autonomous Metropolitan University (UAM), Mexico, in 2006. Upon graduation, she worked for one year as environmental consultant, analyst and laboratory assistant in the Water Quality and Residues Laboratory at UAM. Erika obtained two Master degrees. The first one in Environmental Engineering, from the National Autonomous University of Mexico (UNAM) in 2009; during this period she investigated the biological contamination of source water supplies in the Tula Valley, Mexico, which is a region that has been irrigated with wastewater for over a hundred years. She was awarded with a Fulbright scholarship to complete the second Master, which she obtained from Purdue University, USA, in 2010 in Ecological Sciences and Engineering. Her research back then consisted on assessing the ecotoxicological effects of gallium and indium on soil microbial activities and plants.
In 2012, Erika started her PhD programme at UNESCO-IHE, as part of an Erasmus Mundus Joint Doctorate Program on Environmental Technologies for Contaminated Solids, Soils and Sediments (ETeCoS3). Erika investigated the of the use of fungi as selenium and tellurium reducing organisms and their potential in wastewater treatment and nanotechnology. As part of her programme, Erika also performed research at Paris-Est University and at the Center for Biofilm Engineering in Bozeman, Montana, USA. She has nine years of laboratory experience and research-related work, participated in international conferences and has a number of scientific publications including a book chapter and peer-reviewed journals on her name. Currently, she works as a post-doc at the Center for Biofilm Engineering on the development of fungal biofilms (2016).
