Senior🎓
Top SchoolRajith Vidanaarachchi is a Postdoctoral Research Fellow and AI/Data professional with a PhD in machine learning and 11 years of experience building explainable, deployable forecasting and decision-support systems across research, government and enterprise settings. He bridges deep research—designing neural network architectures and pattern-recognition methods for complex time-series and bioinformatics—with hands-on engineering, delivering cloud-hosted workflows on platforms such as Azure and Replit using Python, R and SQL. Rajith has translated research into impact through applied consulting for clients like WorkSafe Victoria and TAC Victoria and by contributing to production-ready open-source tooling, including C/C++ wrapper work for the high-performance symbolic library SymEngine. He focuses on scalable, measurable automation and forecasting pipelines and is particularly interested in agentic AI and workflow orchestration where ML meets operational decision-making. Notably, his background spans both academic teaching and industry-facing pandemic modelling work, giving him a rare blend of pedagogical clarity and practical emergency-response analytics experience.

Contributions summary:Rajith primarily contributed to the development of C++ wrappers for the SymEngine library, a fast symbolic manipulation library. Their contributions involved implementing wrappers for trigonometric functions, one-argument functions, and other mathematical functions within the C wrapper files. This includes the creation of a macro for one-argument functions, and the addition of tests for those and other functions within the cwrapper framework. Additionally, real double methods and complex methods have been added.
