Career Summary

Biography

In a general form interest in science, particularly technological and scientific research, was always the main goal in my professional carrier plan. Allied to the need of specialized learning, I understand that academic research can provide a level of knowledge to face the professional challenges of the present world.

I am currently a research academic at the University of Newcastle - Australia, where I have been awarded a PhD for studies in corrosion analysis and prediction. I initiated my studies on steel structures as a research trainee in 2004 at the Federal University of Vicosa - Brazil, where I graduated as a civil engineer in 2007. My interest for engineering scientific research lead me to the EESC University of Sao Paulo, Brazil, and as result of completing a master’s degree in structural engineering in 2008, design guidelines for cold-formed composite steel and concrete beams were added to the Brazilian Standard of Steel Design. Research interests include structural reliability and assessment of infrastructure.

Research expertise

  • Corrosion and Deterioration Modelling

Defined as the destruction of a material due to its reaction with the environment, corrosion poses a serious threat to new and existing infrastructure. Understanding such phenomena is detrimental when considering long term prediction of structural service life.

  • Structural Reliability and Assessment of Structures

Detecting the role of existent uncertainties in structural projects in terms of risk and structural failure has been proven to be a major step in modern engineering design, assisting adequate allocation of resources and decision making.

  • Numerical and Computational Methods Applied to Structural Engineering

Once real life applications adopt differential equations for elements of scientific nature, engineering computational methods is a powerful tool for approximating accurate solutions for such complex engineering problems.

  • Experimental Methods and Material Analysis of Structures

Understanding modern engineering experimentation including design, system calibration, data acquisition, analysis and presentation is a key skill for any academic engineer.

  • Structural Stability and Evaluation of Steel Elements and Composite Systems - Theory and Design

The key to efficient structural design is the optimization of the mechanics, properties and behaviours behind the materials and shapes of structural elements. Understanding your structure in accordance with the applicable codes of practice a more reliable, efficient and durable structure can be built.

Administrative

Administrative expertise

The combination of theory with practical knowledge makes a firm ground for the practice of engineering over a range of problems. The application of planning, designing, constructing, maintaining and operating infrastructure while protecting the public and environmental health were some of my responsibilities during the period of two years in which I was employed by a construction execution and consulting firm. Responsible for managing and coordinating several local and interstate sites, administrative skills were essential to ensure efficient, effective, secure and professional execution of the company's infrastructure projects.

Duties involved: Technical supervision of all structure construction; Operative oversight of standard of quality required by the Standards and Norms in regards quality control; Operative oversight of standard of quality for all aggregates and reinforcement steel purchases; Quality control of all sites temporary instalments and supervision of working force; Operative supervision of all exterior finishing work, including insulation and roofing; Maintain daily records of each construction site and report back to office; Gather periodic photographic records of each construction stage and report to office; Development of several small town urban development plans; Assist in overall project legal aspects, design, budgeting, drawing and execution.

Teaching expertise

Teaching is a special calling and for the strong hearted, encompassing many values such as: achievement, compassion, creativity, duty, excellence, growth, knowledge, leadership, perseverance, courage and vision. To teach is to reflect to the younger generation such values so that high standard professionals can have a solid moral base in which to conduct their responsibilities towards society.

Subjects of Expertise Include:

  • Statics and Engineering Mechanics

Introduces basic principles of engineering mechanics, emphasising upon the gaining of real understanding of the laws and principles of mechanics and the ability to analyse and solve problems in mechanics.

  • Engineering Computations and Probability

Understanding and implementing algorithms for a variety of problems where approximate solutions are obtained, the subject introduces the principles of engineering computations and probabilistic statistics, providing solid foundation for later year courses in water, structural and geotechnical engineering.

  • Theory of Structures

Covers advanced methods of analysis for structural systems, emphasising principles of structural analysis of isostatic and hyperstatic elements, plastic design theory and bounding problems. Providing solid theoretical understanding and capability to solve a vast range of structural design challenges.

  • Steel Design

Capacitate students with in-depth skills of assimilation of data, determination of load combinations and design of steel structures and elements by applying knowledge from previous courses, developing necessary professional judgement to produce articulate and concise documents which convey evidence-based understanding of structural steel design concepts.

  • Reinforced Concrete Design

State of the art in-depth training of structural design skills for reinforced concrete and pre-stressed concrete members. Topics include efficient structural design optimisation of the mechanics, properties and behaviour behind the reinforced concrete material and shapes of structural elements in accordance with the applicable codes of practice.

Localized corrosion can be detrimental for steel pipelines and other containment structures such as nuclear waste containers since single wall perforation may have catastrophic consequences. It follows that the quantification and development of such phenomena with time is of practical interest. However, such long term data is scarcely available and anecdotally reported in the literature, granting this publication special consideration amongst its field of research.
