B.S. in Biomedical Engineering, University of Tennessee, Knoxville 

M.S. and Ph.D. in Biomedical Engineering, University of California, Irvine

Rachel June Smith joined the Department of Electrical and Computer Engineering and the Neuroengineering Program as an assistant professor in August 2022. She completed her Ph.D. with Dr. Beth Lopour at UC Irvine in 2019. Her doctoral work focused on the development of computational metrics in scalp EEG data that reflected disease burden and predicted response to treatment in patients with infantile spasms (IS), a potentially devastating epileptic encephalopathy. Rachel completed her postdoctoral training at Johns Hopkins University with Dr. Sridevi Sarma, where she used dynamical systems and control theory techniques to localize the onset of seizures in the epileptic brain from intracranial EEG recordings during single-pulse electrical stimulation. As an assistant professor at UAB, Rachel will continue to collaborate with expert neurologists and use her computational skills to develop novel measures of therapeutic response in patients with neurodegenerative disorders. 

  • Research Interests
    Epilepsy is a chronic neurological disease that affects nearly 60 million people worldwide and is defined by recurrent and unprovoked seizures. If the patient’s seizures are not controlled with anti-epileptic medications, they often lose their independence, and can experience profound behavioral, psychological, cognitive, social, and financial burdens. Currently, diagnosis and treatment of epilepsy involves visual inspection, channel by channel, of electroencephalographic (EEG) signals recorded noninvasively from the scalp or invasively through intracranial monitoring. These methods of EEG assessment are extremely time-consuming, subjective, and often disregard the network phenomena that drive seizure genesis. The Neural Signal Processing and Modeling Lab focuses on the development of novel computational tools that investigate epilepsy with quantitative frameworks to characterize the disease more objectively and accurately. Incorporation of such computational tools into clinical practice will advance current clinical decision support systems, and has the potential to significantly improve treatment outcomes.
