Employment:- Research Associate, Sensors and Devices, National Institute for Nanotechnology, National Research Council of Canada, Edmonton, Alberta. 2006-2012.
- Postdoctoral Fellow, Department of Chemistry, The University of Western Ontario, London, Ontario. 2005-2006.
Education- Ph.D. Physical Chemistry, The University of Western Ontario, London, Ontario. 2005. "Development of Interfacial Force Microscopy:Applications for Materials and Interfaces".
- B.Sc. Chemical Sciences, Monterrey Institute of Technology and Superior Studies, Monterrey, Nuevo Leon. Mexico. 1998. "Synthesis and Characterisation of a Ruthenium Photo-Sensitiser for Low-Cost Solar Panels".
Research:
- Interested in the study of material properties of technologically relevant materials heterogeneous on a sub-micrometre length-scale and errors tracking in nanoindentation experiments.
- Building a new generation environmentally controlled Interfacial Force Microscope (IFM). The construction of this IFM incorporates several important new instrumental features:
- Environmental chamber ~1-105 Pa range with humidity meter and software controlled bleed-in valves
- Encoded sample positioning stage with accuracy of 20nm/1.4mm per axis
- Isolated ground feed-throughs
- Heating/cooling sample stage ~200 to 600 K in vacuo ~255 to 375 K in dry N2 with instability <10 mK.
- A closed-loop scanning stage with 30x30x10μm scan envelope and sub-nanometer precision.
- Studying nano-indentation calibration methodologies and the error they introduce into data analysis; proposed a new mathematical model that helps minimise said error.
- Development of a facile low-cost sapphire indentation tip fabrication process. Planning, design and implementation of a processing station for sapphire indentation tip
- Developing a novel tunnelling-junction micro-fabrication technique in collaboration with Wayne Hiebert (Principal Investigator at NRC-NINT).
- Design and implementation of a dip-coater with an embedded micro-controller for asphaltene sample preparation by a COSI sponsored post-doctoral fellow in the Department of Chemistry at the University of Alberta.
- Advising a graduate student in the Department of Pharmacology on experimental design and interpretation of data obtained from bone cross-sections of test rats.
- Directing a graduate student in the Department of Mechanical Engineering at the University of Alberta in the design of a new MEMS based IFM sensor.
- Consulting for the Integrated Nano-Systems Research Facility at the University of Alberta with regards to their SPM and nano-indentation services.
