Pedro Irazoqui

Prof. Irazoqui is director of Purdue's Center for Implantable Devices, associate head for research and professor in the Weldon School of Biomedical Engineering, and School of Electrical and Computer Engineering. His group develops wireless implantable devices for various potential applications including monitoring and suppression of epileptic seizures; prosthesis control for injured military personnel; modulation of cardiac arrhythmias; treatment of depression, and gastroparesis, a partial paralysis of the stomach; and monitoring and therapeutic modulation of intraocular pressure for glaucoma.

He has been named Showalter Faculty Scholar, and Purdue University Faculty Scholar, both in 2013. He is a senior member of Institute of Electrical and Electronic Engineers (IEEE). He has received multiple teaching awards, the Early Career Award from the Wallace H. Coulter Foundation, and the Outstanding Faculty Member Award from the Weldon School of Biomedical Engineering (2009), as well as the Excellence in Research Award from Purdue in 2010, 2012, 2013, 2015, and 2016. He was elected the College of Fellows of the American Institute of Medical and Biological Engineerins (AIMBE) in 2016. He has been serving as Associate Editor of IEEE Transactions on Biomedical Engineering since late 2006.

Research agenda

I am focused on the modular design of biological implants in general, and newest-generation devices for neuromodulation in particular. Module types include those for wireless power and data transfer, energy storage, and closed-loop neuromodulation with integrated biosensing. These are the three key challenges in my area, and we have demonstrated success in all three. When combined into distinct embedded systems, these modules enable scientists and clinicians working with our lab to conduct high impact and hereto impracticable experiments. Specifically, these devices will enable proposed specific aims to map and functionally control the vagus nerve. These systems also provide novel avenues for translation of treatment of neural disorders through miniature, wireless, closed-loop medical device prostheses. Specific prior and parallel research and clinical applications to this project demonstrate a track record of success and include: i) vagus nerve stimulation for epilepsy and inflammation; ii) pressure sensing implants for eye (glaucoma), heart, and bladder; iii) pelvic nerve stimulation for urinary incontinence; and iv) targeted muscle re-innervation prosthesis control.
