  • About Millie:
          I obtained my Bachelor's and Master's degree in Biomedical Engineering from New Jersey Institute Technology. Under the guidance  of Dr. Bryan J. Pfister, NJIT, my Master's thesis focused on the development of a novel pneumatic blast simulator.  After graduation, I joined the lab of Dr. Viji Santhakumar to study traumatic brain injury acquired epilepsy. Upon acceptance into the Doctorate program at the Graduate School of Biomedical Sciences at Rutgers New Jersey Medical School, I wanted to pursue TBI research, focusing on addressing the mechanistic underpinnings following traumatic brain insult in vitro.
  • Education:
B.S. Biomedical Engineering, NJIT 2009 M.S. Biomedical Engineering, NJIT 2011
  • Research interests: 
          Injuries sustained after an acute traumatic brain injury (TBI), such as a fall or motor vehicle accident, can lead to long-term neurological and cognitive impairments ranging from headache to depression and even epilepsy. The molecular cascades that ensue are secondary in nature but the mechanism initiating these cascades and its effect on neuronal function is unknown. My research focus has been on examining the role of glial cells on neuronal function after an acute traumatic insult.
  • Present research/Project summary:
         To date, effective treatments for cognitive and behavioral symptoms of mild traumatic brain injuries are lacking. However, an anti-inflammatory cytokine, leukemia inhibitory factor, (LIF), also has been shown to exert as neuroprotective effects after a mild TBI in vivo. The mechanism(s) underlying its neuroprotective effects has not been elucidated. The goal of this project is to determine whether LIF has direct and/or indirect effects on neuronal function after injury and the mechanism(s) underlying these effects.
