Felipe Santiago Salinas, Ph.D.

Assistant Professor/Research - Department of Radiology, UTHSCSA

Chief, Transcranial Magnetic Stimulation Division - Research Imaging Institute, UTHSCSA

Research Health Scientist - Department of Veterans Affairs, South Texas Veterans Hospital

In my research, I utilize a multidisciplinary approach (i.e. physics, computer science, mathematics, engineering) to address current problems in medicine and biology. Specifically, I am interested in refining current imaging modalities and computer modeling techniques for applications to psychiatric, circulatory and neurological diseases and disorders. My predoctoral research focused on the development of the physics-based computations of electromagnetic field modeling in biological tissues. Modeling of the electromagnetic interactions with neurological tissues (and any resulting neuronal activations) requires extensive training in physics, imaging and neuroscience. This predoctoral training equipped me with a strong background in each of these fields.

Over the past decade, I have broadened my areas of expertise by continually stepping outside of my scientific comfort zone—while progressing down a consistent, logical biomedical research path. Through my postdoctoral work (on two NIH-funded R21s), I oversaw the development of a functional imaging baboon model—consisting of structural & functional MRI, positron emission tomography, transcranial magnetic stimulation (TMS), electrophysiology (surface & intracranial EEG, EMG), image analysis (resting-state, structural equation modeling (SEM), independent component analysis (ICA)), connectivity-based parcellation (CBP), physics-based neural computations, and graph theoretical analysis. While being trained in a broad array of current imaging modalities and techniques, I was also active in the experimental design and statistical analysis of these imaging projects. I am an expert in multi-modal neuroimaging acquisition and analysis and neuromodulation.
