The PhD thesis builds on several empirical studies that investigate the relation between the presence of particular OO design attributes (i.e. Code Smells) and increased maintenance effort (time), increased code change size (churn), increased number of defects and higher likelihood of problems during maintenance. August 2005 ∼ June 2007: MSc. in Software Engineering and Management – IT University of Göteborg, Sweden Thesis title: “Testing a radiotherapy support system with QuickCheck”. The thesis comprised an experimental evaluation of lightweight formal methods (i.e., Quviq QuickCheck®) for conducting system-­‐
level testing within the medical domain. The test harness for integrating QuickCheck and the development environment (Microsoft .Net) was implemented via remote procedural calls. Random test cases were generated automatically from a mathematical model representing a safety property (i.e., system accuracy). January 1999 ∼ August 2004: BSc. Eng. in Computer Science – Costa Rica Institute of Technology, Costa Rica Thesis title: “Performance benchmarking of MPI and PVM distributed environments by using a 3D renderer” A Ray Tracer was used as the client application for this benchmark. The project included the implementation of the Ray Tracer from scratch, including CSG (Constructive Solid Geometry) and anti-­‐
aliasing features. CAREER ACHIEVEMENTS April 2015 ∼ Present: March 2013 ∼ June 2015: August 2012 ∼ December 2014: August 2007 ∼ July 2012: Oslo and Akershus University College of Applied Sciences (http://www.hioa.no) Position: Adjunct Associate Professor I conduct research within Information Technology and supervise BSc. and MSc. students. Mesan AS (http://www.mesan.no) Henrik Ibsens gate 20, 0255 Oslo, Norway Position: Senior System Consultant I work mainly as a quality advisor, and in addition I provide system development/integration services. I specialize on a variety of QA related services: Application Portfolio Assessment, Product Quality Assessment, Certification Support and Process Assessment and Improvement. My most recent project consisted of leading and conducting a Software Due Diligence Assessment for a multinational logistic company. I have also worked as a facilitator for a pre-­‐
project analysis for a modernization initiative in a major retailer company. I have worked as both developer and architect in several projects involving SOA systems, with technologies such as
J2EE, Eclipse, IBM Rational Team Concert (RTC), IBM DB2, and Sparx Enterprise Architect. Simula Research Laboratory (http://www.simula.no) P.O. Box 134, 1325 Lysaker, Norway Position: Adjunct Research Scientist I worked in the Software Engineering department, where I conducted research mainly in the area of Software Evolution and Empirical Software Engineering. My research strives to integrate project-­‐related metrics with software metrics (e.g., code smells) to achieve better maintenance effort estimations, to develop context-­‐aware defect prediction models and to support code-­‐
restructuring decision-­‐making. I have ongoing collaborations with the following universities: Brunel University, University of Poznan, TU Delft, Polytechnique Montréal, and the University of Milano-­‐Bicocca. Simula Research Laboratory Position: PhD Research Fellow Research topic: Assessing the capability of software design metrics (i.e., code smells) to support th
maintainability assessments. Thesis defended in October 15 , 2012. 1 of 5
January 2007 ∼ August 2007: January 2005 ∼ August 2005: •
I conducted a large-­‐scale, experimental study by planning and executing a maintenance project for Simula Research Laboratory at a total cost of 50,000 Euros. In this project, I negotiated the terms of the contract to outsource services in Eastern European software companies, acted as Simula representative and project manager. I was the main responsible of the design and execution of the study, including collection and analysis of both quantitative and qualitative data. Due to the lack of proper tools for software design and evolution analyses, I also had to develop from scratch many of the solutions for conducting repository mining and data extraction, e.g., via SVN libraries available for Java. •
Other responsibilities in this position included: collaboration with industrial partners, and presentations at scientific and industrial venues. I also supervised a MSc. Thesis at University of Oslo: “A Literature Review on Code Smells and Refactoring”, 2010. (See link: http://www.duo.uio.no/sok/work.html?WORKID=103363 ) Micropos Medical AB (http://www.micropos.se) Stena Center 1, SE-­‐412 92 Göteborg, Sweden Position: Software Consultant •
The first stage of the project consisted of migrating the software component of the product (a medical device to track organs in real-­‐time to support safe radiotherapy treatments) from LabView to C# .NET. I also developed the technical platform necessary for conducting model-­‐based, system-­‐level testing (i.e., by harnessing Quviq QuickCheck® to .NET platform). This was done to test several safety properties of the medical device. •
The second stage of the project consisted of designing, implementing and documenting the graphical user interface (GUI) and the architecture for the product. During this stage we worked in close collaboration with physics engineers, electrical engineers, graphical designers, physicians, and nurses. th
Kamiya Consulting Inc. (http://www.kamiya.com) 2560 9 Street #218, Berkeley, CA 94710 USA Position: Software Engineer •
January 2004 ∼ January 2005: I was responsible for the redesign and migration of segments of e-­‐commerce modules based on Microsoft VB/ASP into J2EE platform. I also trained the staff on Java technologies and Object Oriented modeling and programming. Intel Corp. / Siemens Business Services (http://www.intel.com) Ultra Park, Heredia, Costa Rica Position: Software Engineer •
I successfully coordinated and completed a project for developing a Java-­‐based graphical application for defining/executing test-­‐scripts (in Perl) for testing Intel chips. In a normal basis, I worked closely with customers by using agile development methods (i.e. SCRUM) and I was in charge of process analysis/improvement initiatives, requirements elicitation, design, implementation and testing of software artifacts.
