Current Graduate Students


Liora Greenberg

lab pic 2.jpg

Liora is a sixth year graduate student specializing in cognitive and affective neuroscience. After earning a masters degree at Vanderbilt University, and subsequently working as a staff clinician in Penn State’s Psychological Clinic, Liora developed an interest in clinical neuropsychology. Her primary research interest focuses on the neuropsychological effects of mild traumatic brain injury (mTBI). Liora’s master’s thesis examined the impact of mTBI on processing speed and individual reaction time components using drift-diffusion computational modeling. Her minor research project explored mTBI and symptom duration in a college sports setting.  Liora plans to investigate this topic further in her dissertation, studying post-traumatic headache, as well as the relationship between genetics and clinical recovery from sport concussion. When not in the lab or clinic, Liora enjoys spending time with her family, eating (plants!), and being a Suzuki mom.

Meg Cadden

Meg is in her sixth (and final!) year in the lab. She earned her Bachelor's degree from Bates College in 2011, and after graduation, accepted a clinical research position at Boston University School of Medicine as a research assistant at the Memory Disorders Research Center. She is currently engaged in various projects examining cognitive and emotional functioning in Multiple Sclerosis (MS). Her master's thesis examined predictors of employment status among individuals with MS and her minor project explored the relationship between stigma, depression, and disease progression in individuals with multiple sclerosis. She received the 2015 Scott and Paul Pearsall Scholarship from The American Psychological Foundation (APF) to conduct her minor project! Her primary research interest is the interface of emotion and cognition in neurological disorders. She is exploring  this topic further in her dissertation by examining how cognitive reserve moderates aspects of this complex relationship. In 2018 she was awarded the Benton Meier Neuropsychology Scholarship from APF to help fund her dissertation!

 

Cristina Roman

Cristina joined the Arnett Lab in summer 2014. She received her Bachelor's degree in Psychobiology from the University of California, Los Angeles (UCLA). Cristina is currently engaged in projects aimed at examining structural and functional brain changes in MS and how they relate to cognitive functioning and depression. She hopes to further examine the neural subtrates of MS through diffusion weighted imaging, volumetric analyses, and resting state functional connectivity. Her long-term objective is to develop a research program built on a symbiotic relationship between research and practice by utilizing neural substrates as diagnostic tools and treatment guides for individuals recovering from neurological and psychological disease. Cristina will be completing her pre-doctoral internship at The Charleston Consortium Internship Program, a joint endeavor of the Medical University of South Carolina and the Ralph H. Johnson Veterans Affairs Medical Center.  

 

 

Erin Guty

Erin joined the lab in fall 2015. After receiving her bachelor's degree from Princeton University, she worked at Harvard University, researching the cognitive and social cognitive deficits experienced by individuals with schizophrenia through the use of clinical neuropsychological evaluations and MRI scans. Erin is currently working on projects evaluating the factors that relate to deficits in cognitive and emotional functioning following concussion. She is primarily interested in the underlying mechanisms of cognitive deficits in individuals with neural dysfunction and the factors contributing to individual resiliency and vulnerability to such deficits with the ultimate goal of finding targets for intervention. She completed her Master's Thesis in 2017 and is the current Program Coordinator for the PSU Sports-Related Concussion Program. Erin's poster entitled, "Executive Functioning in College Students with Chronic Post-Concussion Symptoms" won first place in the Social and Behavioral Sciences Category at Penn State's 2018 Graduate Exhibition.

 

Kaitlin Riegler

Kaitlin is in her first year in the lab. She received her Bachelor’s degree from The George Washington University in 2013. Before joining the lab, Kaitlin worked for three years at Princeton University as the project coordinator for the NCAA-DOD Concussion, Assessment, Research, and Education (CARE) consortium longitudinal clinical study. While at Princeton, she also worked as a project coordinator for the Big 10-Ivy League Academic Alliance “Epidemiology of Concussion in Ivy League/Big 10 Sports” project. Kaitlin is currently working on projects evaluating rates of depression in sport-related concussion. She is primary interested in identifying risk factors for prospectively sustaining a concussion and psychological factors impacting clinical recovery time and return to baseline neurocognitive functioning post-injury.
