Simard Lab

Dr. J Marc Simard's laboratory investigates molecular mechanisms of cerebral edema formation, blood-brain barrier dysfunction, and neuroinflammation after acute and chronic CNS injury.

The laboratory's efforts led to the discovery of the novel SUR1-TRPM4 channel, which contributes to secondary injury after stroke and traumatic brain and spinal injury.

Multiple clinical trials have directly stemmed from this work, including the ongoing phase III multisite CHARM trial, which investigates the use of the SUR1 inhibitor glyburide to reduce cerebral edema after ischemic stroke.

Translational Therapeutics Research Group (TTRG)

The TTRG is led by Graeme Woodworth, MD, Anthony Kim, PhD, and Jeffrey Winkles, PhD. Research is focused on a variety of projects related to the diagnosis and treatment of brain tumors.

Dr. Winkles is currently investigating cancer cell signaling pathways of TWEAK-inducible genes, including Fn14, which stimulates cancer cell growth, migration, invasion, and differentiation.

Dr. Kim studies the use of targeted nanoparticles to enhance delivery of therapeutic agents to glioma and metastatic cancer cells.

Dr. Woodworth's ongoing work focuses on developing new diagnostic and therapeutic applications of MR-guided focused ultrasound in brain tumor treatment.

The Ksendzovsky Lab

Drawing of neuroengineering

When faced with high energy demands, the brain adjusts its metabolic response, yet the cellular basis for how this occurs or if these changes play a role in epilepsy remains unknown.

The Ksendzovsky lab is interested in combining electrophysiology and molecular techniques to study the fundamental role metabolism plays in regulating neuronal activation and epilepsy.

To do this, we leverage access to human intracranial recordings during epilepsy monitoring to identify, segregate and analyze epileptic and normal brain tissue.

These findings are translated into in vitro and in vivo models which we use to explore mechanisms underlying the metabolic control of neuronal activity and epilepsy.

See publications from the Ksendzovsky Lab.
