Areas of interest

Biomedical image processing

I apply computational techniques to analyze tissue samples images. I extract meaningful information from different modalities (i.e. histology, imaging technique such as mueller polarimetry) and cross-reference them, helping in the understanding and diagnosis of diseases across mutiple levels.

Medical data visualization

I create medical data visualization tools through user-friendly GUI-based python or web-based applications, allowing healthcare professionals and other researchers to interactively explore and interpret complex medical datasets.

Quantitative image analysis

I measure and analyze various features, such as intensities, shapes, textures, and spatial relationships within the images to identify pattern in images. This allows to characterize structures such as diseases in medical images.

My latest projects

Dec, 2023

I published a python and matlab-based codebase allowing to register histological images with polarimetric images with minical user interactions, and to quantify the polarimetric parameters in different brain regions

Mar, 2023

I published a python and matlab-based codebase allowing to analyze the effect of various conditions (such as formalin fixation, freezing, etc...) on brain samples over time
