About Me

I am an electronics engineer with a Ph.D. in biomedicine and a very passionate person about giving solution to any tech challenge or improving the operation of almost anything through technology. I have focused my efforts in web implementations and services using PHP and more recently Python. In this learning journey, I have worked in a myriad of fields helping lawyers, marketing experts, software developers among others and I have visited several countries as well. I also ventured research, where medical imaging and data mining are my daily routine. Let me know what your technological need is and let's put hands on it

Projects

Some of the projects I have executed are even serving on-line or have multimedia records. Some others, despite very interesting have been developed to companies that kept the right to use and show, so I am not allowed to put that material here.

Scientific Contributions

Not that I do not believe in collaborations, but here I just post what I proposed, executed and published as a project leader

A python implementation ready to be connected to existing tools in hospitals. This code library uses the masks that separate the tumors in medical images to quantify the edge spiculation. Edge irregularities are common in aggressive cancer, and this implementation shows numbers in an easy-to-interpret histogram. The evolution of this idea will be able to detect cancer from images and define its status with high accuracy, so diagnosis is accomplished faster, more accurately and without the need of the often painful histologies.
In this development we let the machine to solve a difficult problem for humans: to define when the patient is healthy, has a mild cognitive impairment or is currently suffering from Alzheimer disease. To accomplish this, we feed the computer with geometrical features extracted from cortical structures in the brain. Additionally, we present to the medical community, the regions of the brain that show a higher probability of being affected by the malady.
The tractography is Magnetic Resonance based technique that tracks the displacement of water molecules. The trace of water has a preference in regions where myelin -- a lipidic substance that covers neurons -- is in place. As myelination is a process that parallels maturation, it is possible to monitor maturation through tractography. We executed this technique in a cohort of 49 patients, 24 them born prematurely. Among other interesting findings, we managed to capture the catch up effect that allows premature babies to be equally capable than born term children.
This is hardware effort to increase the quality of MRI images in small animal imaging sessions. The idea is to create MRI receptors, make them smaller, stick them together and thus, recover the field of view lost with the smaller devices. The problem is that mutual induction appears when you put the small receptors close to each other. We proposed and successfully tested alternatives to eliminate the mutual induction in intimate coils and reduce the cross talking among 2nd and 3rd order neighboring.
This is not an evolution of the EdgeRunner algorithm. This is a new approach that verifies the existence of spiculations in the masses by correlating the findings on two planes (axial and sagittal). The implementation still runs along the edge, but the peak detection mechanism is based on derivatives and filters. The results are presented in the same histogram fashion as in the original EdgeRunner algorithm.
