My research is related to statistical learning, mainly kernel machines and neural networks, for Earth Observation and remote sensing data analysis.
I'm interested in understanding human vision from information theoretic principles. This statistical view has implications in experimental and computational neuroscience. (See the ex-cathedra statement)
My interests are related to machine learning and signal and image processing. The application domains are remote sensing data analysis and hyperspectral images with special focus on cloud screening.
At present I'm focused on kernel methods, support vector machines, semi-supervised and active learning. The main application field is on remote sensing data. I have recently worked with one-class classifiers applied to hyperspectral images.
My current research involves signal processing to develop new interactive man-machine interfaces and haptics, and real-time multispectral sensors and actuators. I'm also with Analog Devices Inc.
I'm working on image fusion, developing downscaling and pansharpening methods. The goal is to tackle multitemporal image fusion and change detection problems with improved resolution.
My research activity is centered in the retrieval of soil moisture and vegetation biogeophysical parameters from space observations (microwave radiometers, radars and hyperspectral imagers), and the development of multi-sensor downscaling techniques for enhanced information.
I'm working in image statistics and vision science. I have developed several methods for density estimation, measure independence, manifold learning and visual quality assessment.
My background is on metric learning and kernel machines. I'm currently a postdoc at the ISP, working on feature extraction and classification problems in remote sensing cloud detection.
My primary research interests lie in the area of Monte Carlo methods for Bayesian inference. My specialty is focused on the random number generation problem and computational methods for stochastic quadrature, such as rejection sampling, MCMC algorithms and importance sampling techniques. I also have interests in certain subjects in stochastic processes, nonlinear dynamics, chaotic systems and time series analysis.
I've been working on neuroscience, investigating how the brain interacts during perception and how this information is used in learning and decision-making processes by means of two-photon imaging or single cells recordings. Now, I'm focused on the visual system, and study the processes that take place in the brain from the moment we see an image until we get information out of it.
