Professional Interests:

The Translational Stem Cell Neurobiology Laboratory studies brain disorders in which inhibitory interneuron function is compromised, such as schizophrenia, epilepsy and autism, with the aim of developing novel therapeutics for these debilitating disorders.

Inhibitory interneurons are abnormal in schizophrenic brains. To find a better way to treat schizophrenia, we need to understand what goes wrong in diseased neurons. Now we can make schizophrenia inhibitory interneurons from stem cells that are made from patient skin cells. We are studying these patient neurons to find out what is causing their abnormalities. This study could lead to novel and more effective therapies for schizophrenia.

One in 25 people experience a seizure at some point in their life and 30% of them have seizures that cannot be treated with anti-seizure medication, presenting desperate need for the development of novel and more effective treatments. We have shown that transplantation of stem cell-derived human interneurons effectively reduce seizures and other brain abnormalities in animal models of epilepsy. We are further developing this novel therapeutics for the purpose of clinical translation.
