Postdoctoral Researcher

I started research working in a cognitive neuroscience lab at Christian Brothers University. After receiving my BS in Natural Science, I joined Dr. Nicholas Simon’s lab at University of Memphis where I earned my Masters and PhD in Experimental Psychology/Behavioral Neuroscience. My research focuses on the neurobiological processes that integrate rewarding and punishing information to guide behavior, and the relationship between disruptions to these processes and the development of mental illness.

Postdoctoral Researcher

My research experience began at Purdue University with a Master of Science in computational chemistry (thesis advisor: Sabre Kais) then transitioned to two research projects: 1) a theoretical and experimental examination of light interacting with a gold nanorod array and 2) the label free detection of biological pathogens (Ph.D advisor: Alex Wei) with a portable device.  My next stop was post-doctoral study at University of North Texas (PI: Vladimir Drachev) designing and fabricating nanostructures to enhance fluorescence.  I am currently working on studies combining neural imaging with behavior to identify neuronal correlates of fear and safety learning in rodents.   ​

Graduate Student

While completing my undergraduate honors thesis at University of Colorado – Colorado Springs (UCCS), I used EEG to analyze attentional biases in correlation with Optimistic and Pessimistic personalities. Through this experience I developed a passion for neuropsychological research and expanded my neuroscience experience by working in the epilepsy and neurology department as an EEG Technologist at Children’s Hospital of Colorado. Assisting with epilepsy surgeries, I acquired in-depth knowledge of neuroanatomy and behavioral correlates. This sparked my desire to apply this knowledge to neuropsychological research and fuse it with my passion for studying neurological constructs of PTSD. My research interests include investigating the neural circuitries involved in fear expression and fear suppression to explore new avenues of PTSD treatment interventions. 

Izabela Caliman, PhD            


Research Analyst
I got my BS in Pharmacy and my master’s and PhD degrees in Physiological Sciences at the Federal University of Espirito Santo, Brazil. I started my research career investigating cardiovascular parameters, but the brain as an organ never ceased to fascinate me. It was during my PhD as a visiting scholar at Dr. Anantha Shekhar’s and later as a postdoc at Dr. Philip Johnson’s lab at IU that I started exploring how the brain controls autonomic and behavioral responses to stress and anxiety. I am particularly interested in applying circuitry-based manipulations to key brain networks to dissect how neural ensembles orchestrate responses to stress and motivation.
