Alex is one of the very few Survey and Cartography Instructor in the area who published maps of underwater
caves and he received awards for his work. This allows him to teach with much more insight and a practical approach
to surveying. Samples of his work can be seen in the cave section of this web page.
He has participated as an underwater explorer in the hydrological research project of the caves in the X'cacel area, directed by SEDUMA and the University of Quintana Roo.
He has participated as cartographer of underwater caves in the study project of the fortified city of Mayapan, led by archaeologists from INAH and the United States, where he made a detailed map of the sacred cenote Sac Uayum, important for the numerous anthropological and archaeological findings.
He was recently appointed as underwater cave cartographer of the Gran Acuifero Maya project, replacing his friend and mentor Bil Phillips who passed away in November 2017.
