Who am I?

I am a statistician that applies data-driven methodologies to develop solutions to solve complex problems. I am a fast learner with the passion of discovering new things.

I have pursued a doctoral degree with the aim of deepening my knowledge, and I have experience in statistical consulting as well as software development. Most the projects I was involved in required efficient algorithmic solutions, coupled with the development of user interfaces to allow user-friendly applications.
The things that I look forward the most in a problem are challenges and novel solutions. Because of this, I have worked on a range of different topics, such as 3D meshes, stochastic optimization, and efficient algorithms.

Publications

Monitoring of complex geometrical shapes

I developed an innovative statistical quality control method for detecting shape defects in complex geometries obtained via additive manufacturing. I introduced a novel nonparametric control chart based on kurtosis analysis which provides superior defect detection for 3D-printed objects compared to existing approaches. A paper detailing the methodology has been submitted for review.

A doubly-stochastic constrained optimization algorithm

I designed a novel stochastic optimization algorithm with stochastic constraints, aimed at optimizing control chart tuning parameters with greater efficiency compared to traditional numerical methods. This innovative approach has been published in the Journal of Quality Technology.

Journal article  

An improved bisection-type algorithm for control chart calibration

I developed a modified bisection algorithm for computing control limits in complex settings where standard methods are inefficient. The approach removes the need for a predefined search range and scales efficiently to multi-chart scenarios. The method has been published in Statistics and Computing.

Journal article  

A General Framework for Monitoring Mixed Data

I developed a general methodology to monitor processes involving mixed-type data (continuous, ordinal, categorical), common in real-world applications. The method enables effective sequential monitoring under serial correlation and has been published in the Journal of Quality Technology.

Journal article  

Alternative parameter learning schemes for monitoring process stability

I formalized the theoretical behavior of parameter learning schemes in relation to outlier detection performance in control charts. This work enabled the generalization of alternative parameter learning methods, leading to a more efficient and accurate detection scheme compared to traditional approaches. This work has been published in Quality Engineering.

Journal article  

A software for modern statistical process monitoring

I developed a Julia package for real-time statistical process monitoring, integrating advanced algorithms and control charts to handle complex data types, such as sequential data, functional data, and structured observations. A paper illustrating package is set to appear in the Journal of Statistical Software (2025+).
