Born at Huánuco, Peru. June 5th, 1975.
Nationality: Peruvian.

Professional Objective:
To continue developing a strong expertise in natural resources evaluation and management in a position where my academic and professional background in these areas can be effectively used yielding appreciable organizational and personal benefits.

Employment History:

September 2005 to

University of Alberta, Centre for Computational Geostatistics       Edmonton, Alberta
PhD. Candidate, Research and Teaching Assistant
Previous research covered the improvement of Indicator Simulation algorithms, integrated geometric and probabilistic criteria for ore resources classification, flexible change of support procedures, linear and non-linear estimation with training images and nugget effect inference.
Current research is focused on spatial modelling with location dependent statistical moments and non-stationary geostatistics.
Also performed the geostatistical analysis of gold assays from the “Molejón” property (Petaquilla Minerals Ltd., Panama), as well as location dependent variogram modelling for the Surmont oil sands project (Conoco Phillips, Alberta).
