Dr. Hernandez's research interests are focused on developing and integrating techniques for the study of brain function.
He has been involved in BOLD (Blood Oxygenation Level Dependent) and ASL (Arterial Spin Labeling) Functional MRI research for a number of years. Primarily, he has been developing ASL methods for quantitatively imaging cerebral perfusion. Perfusion is an indicator of brain function and therefore a very valuable tool, not just for the clinician, but also for the neuroscientist and psychologist. He is currently working on kinetic models for quantifying the ASL signal, and techniques that will improve the SNR and temporal resolution of perfusion measurements.
Dr. Hernandez is also working on developing methods for non-invasive brain stimulation techniques. He has worked on the design and analysis of transcranial magnetic stimulation (TMS) devices, and is also active in the development of focused ultrasound neuromodulation technology.
Finally, he has collaborated tightly with research groups in psychology and neurology in the study of attention, memory, pain and depression.
