My interests are focused towards bridging the gap between instrumentation, experiments, analysis and presentation. Be it using DIC methods to study microtubules or Polarized light microscopy to elucidate the uniquiness of graphine: Signal processing, image analysis, machine vision are some of the key components required for 2D and 3D object recognition, segmentation, detection and tracking.
Visualization of meaningful data combining differents layers or objects is the culmination of this pipeline. Developing algorithms for cleaning, suppressing and highlighting information has become a key in The Age of Big Data.
