As a physicist and expert in MR these are some of the ideas I am interested in doing research on. If you have an idea or a project or just want to discuss it please contact me.

 

  • I am interested in understanding the role of astrocytes in plasticity
  • I am interested in understanding the mechanisms of cortical plasticity at all levels.
  • I am interested in understanding the role of resting states. 
  • I am interested in finding clinical applications (not just diagnostic applications) to MR.
  • I am interested in using MR to work on mental illnesses helping the treatment and not just detection.
  • I am interested in Devellopping Medical Physics technologies and knowledge in general.
  • Applications of wavelet analysis.

Functional Magnetic resonance.

 

Functional magnetic resonance is a technique that measures the flow of fresh blood that travels to a brain region that shows some activity. This new fresh blood has different magnetic properties to used blood and therefore can be measured by our scanner. There is a broad range of applications including: Clinical applications, research in psychology and research in neurosciences.

I have personally used these scanners to show the brain activation of viscous and tasteful stimuli in the mouth. I have also used it to study recovery from brain injury monitoring the evolution of a subject. Finally I have used it to study brain connectivity in the special case of anaesthesia and pain. I am interested in understanding the mechanisms that drive these sensations.

Resting-States

 

This is a technique inside functional magnetic resonance. In contrast to a standard fMRI experiment, there is no stimulus delivered to the patient. All the activity the patient has is rest in silence while the scanner acquires images of the whole brain. After a heavy post-processing of the images, we find that there are a series of brain regions that are working together in a correlated manner. What is the origin of this effect and which are their implications? it is known that these nets change with illness like Parkinson’s, Alzheimer’s or even Diabetes.

In the past I have studied these networks finding that they change with experience. Actually I am working with Epileptic patients trying to see how these networks change with time.

Resonance, Obesity and Nutrition.


MRI allows us to study the insides of the body without harm and without using radiation. This makes this technique perfect to study what is the fate of food in the stomach or the digestive system in general.

In the past on top of studying the effects on the brain of food, I studied accommodation of alginate based meals in the stomach and their effect on satiety. In this moment I am looking at the possibility of studying the stomach under the effects of hormones as well as the activity and function of abdominal fat in the sensation of satiety and hunger.

Medical Physics.

 

I have been apointed as head of the Medical Physics group in my University. Because of that I am planning to create a fully equiped lab to be used by students and researchers. I also plan to promote the B.Sc. in the Faculty till it gets national and international recognition. Anyone interested in collaborating please let me know.
