Dr. Cullen and Dr. Smith have an article published in Scientific American titled "Bionic Connections" descrubing their efforts to develop biohybrid neuroprosthetic interfaces (http://www.scientificamerican.com/article.cfm?id=how-artifical-arms-could-connect-nervous-system). In addition, the magazine published a web-based companion article on the use of this neural tissue engineering technology to repair peripheral nerve injuries (http://scientificamerican.com/article.cfm?id=bionic-limb-researchers-build-new-bridges-nerve-injury).
Dr. Wolf and Laura Struzyna gave nanosymposium presentations at the Society for Neuroscience conference in New Orleans, LA. Dr. Wolf presented "Alterations in Hippocampal Circuitry Post Diffuse Brain Injury in a Swine TBI Model". Laura Struzyna presented "A Stragey for Functional Restoration of Brain Pathways Using Micro-Tissue Engineered Constructs Containing Living Axon Tracts".
Dr. Cullen gave a lecture at the Military Health System Research Symposium (MHSRS) in Ft. Lauderdale, FL detailing his recent work in "Acute Biophysical Responses and Neurophysiological Sequelae following Closed-Head Traumatic Brain Injury in Swine".
Commentary by Dr. Cullen was featured in a blog post about brain-based neural electrical interface systems: innovation-how-a-paralyzed-peson-uses-thoughts-to-control-a-robotic-arm
Dr. Cullen was interviewed for a blog post regarding the effects of traumatic brain injury on NFL athletes: http://physicsbuzz.physicscentral.com/2012/05/physics-of-hit-football-concussions.html
The Cullen Lab was awarded a grant from Axonia Medical, Inc. to advance novel neural tissue engineering technology to improve neuroregeneration following severe peripheral nerve injury.
A new company, Cerebid Technologies, has been formed by Dr. Cullen along with Ray Krauss, Douglas Smith and Shu Yang, to focus on translating their unique blast-sensitive photonic nanocrystals. These photonic nanocrystals, which change color following exposure to blast, are being developed as a "Blast Badge" to measure an individual soldiers blast exposure levels relative to thresholds for blast-induced traumatic brain injury, the "signature injury" in warfighters in Iraq and Afghanistan.
Dr. Cullen was invited to give a research talk at the Neuroprotection Research Seminar Series through the Shock, Trauma and Anesthesiology Research Center (STAR-ORC) at the University of Maryland School of Medicine, Baltimore, MD. He presented "Closed-Head Blast vs. Inertial TBI: Cellular Biophysical Responses and Neurophysiological Sequela".
Dr. Cullen was an Invited Speaker at the 2nd World Congress on Biotechnology in Philadelphia, PA. He presented "Neural Tissue Engineering Strategies for Cell Replacement and Axon Regeneration".
Dr. Cullen gave Neurosurgical Grand Rounds at the University of Rochester in Rochester, NY entitled "Altered Neurophysiology and Neuropathology following Closed-Head TBI".
Dr. Cullen was an Invited Speaker at the Department of Defense Advanced Technology Applications for Combat Casualty Care (ATACCC) Conference in Ft. Lauderdale, FL. He presented "Neuropathological and Functional Changes following Non-Impact, Closed-Head Acceleration/Deceleration-Induced TBI".
Dr. Wolf and Ms. Mietus gave platform presentations at the Biomedical Engineering Society Annual Meeting in Hartford, CT. Dr. Wolf presented "Biohybridized Neural Tissue Engineered Constructs for Electrical Interface with Peripheral Nerve". Ms. Mietus presented "Neural Cell Biophysical Responses in Blast-Induced Traumatic Brain Injury".
BioTech Strategy Blog recently featured Dr. Cullen's work to advance neural tissue engineering technology to develop bionic interfaces and to promote nervous system repair (http://biotechstrategyblog.com/2011/07/how-we-may-be-able-to-rebuild-the-six-million-dollar-man.html/). This work is being done in collaboration with Drs. John A. Wolf and Douglas H. Smith, University of Pennsylvania.
Dr. Cullen was interviewed for a story on Blast-TBI on KYW Newsradio 1060. The story and a link to the audio can be found at: http://philadelphia.cbslocal.com/2011/06/03/part-1-the-signature-injury-of-the-afghanistan-war/.
John Wolf and Constance Mietus each had their abstracts selected for oral presentations at the Annual Meeting of the Biomedical Engineering Society this fall in Hartford, CT. John will be presenting our work on "Biohybridized Neural Tissue Engineered Constructs for Electrical Interface with Peripheral Nerve" and Constance will be presenting "Neural Cell Biophysical Responses in Blast-Induced TBI".
Dr. Cullen was an Invited Speaker at the Trauma Mechanics Research Center at the Univ. of Nebraska-Lincoln where he presented "Biophysical Responses and a 'Signature' Neuropathology in Blast-Induced TBI".
