Post-Doctoral Fellows

Elizabetta Ambron Elizabetta Ambron

Elizabetta is a post-doctoral research fellow in the LCNS at the University of Pennsylvania. She received her PhD in Cognitive Neuroscience and  Experimental Psychology from the University of Edinburgh.  She is broadly interested in apraxia, attention, executive function, and motor control. At the LCNS, Elizabetta’s current research involves using non-invasive brain stimulation techniques (i.e., TMS- transcranial magnetic stimulation) to investigate body representation and motor function in stroke patients.

Denise Harvey Denise Harvey

Denise is a post-doctoral fellow with a joint appointment at the University of Pennsylvania (LCNS) and Moss Rehabilitation Research Institute (Language and Aphasia Lab). She received her PhD in Cognitive Neuroscience from Rice Universityin 2014. Her graduate research examined in healthy subjects and aphasic patients how words and their meanings are retrieved when speaking and understanding language to determine the extent to which the cognitive and neural mechanisms that support both language production and comprehension overlap. Denise’s current research expands on this work by investigating the role of cognitive control in language processes. She implements a variety of methodological approaches to investigate the neural substrates of language, including neuromodulation (i.e., TMS and tDCS), voxel-based lesion symptom mapping (VLSM), diffusion tensor imaging (DTI), and task-based and resting-state fMRI. To this end, her work aims to elucidate the functional and neuroanatomical architecture of the language system to inform the use of behavioral and neurorehabilitative techniques and facilitate recovery of language impairments following brain damage.

Rachel Wurzman Rachel Wurzman

Rachel is a post-doctoral research fellow in the LCNS at the University of Pennsylvania. She received her PhD in Neuroscience in 2014 from the Interdisciplinary Program in Neuroscience at Georgetown University. She is broadly interested in neural factors and technologies with the potential to dynamically affect plasticity in integrated sensory and motor circuits whose wiring, and sometimes mis-wiring, contributes to neuropathological brain function. Rachel's predoctoral research background was in motor systems and clinical neurophysiological approaches to studying movement disorders. Her doctoral dissertation research focused on the influence of specific neuro-developmental guidance molecules on the development and function of circuits in the brain that are commonly implicated in developmental neuropsychiatric disorders. At the LCNS, Rachel’s current research involves using non-invasive brain stimulation techniques (i.e., TMS- transcranial magnetic stimulation, and tDCS- transcranial direct current stimulation) to investigate markers of brain plasticity that may predict functional recovery and facilitate neurorehabilitation in stroke patients with language impairments (e.g., aphasia). Additionally, she is interested in understanding and influencing neural plasticity by combining neurophysiology methods such as electroencephalography (EEG) with tDCS and TMS. Using this approach, Rachel also studies the fundamental mechanisms by which tDCS affects neural substrates, from cells to circuits. Besides empirical research, Rachel also publishes work on (neuro-)ethical, legal, and social implications of neurotechnology development.

Research Staff

Clinical Coordinators
Olufunsho K. Faseyitan Olufunsho K. Faseyitan

Olu is senior researcher and lab manager for the LCNS'. He provides technical support for TMS and tDCS projects in the lab. He is also responsible for data collection and data analysis of functional neuroimaging studies in the lab. Olu received a Bachelor of Arts from Purdue University and a Masters of Science from Villanova. His research interests are in the cognitive processes that support attention, language, and memory. Olu is particularly interested in the use of neural stimulation techniques (i.e. TMS & tDCS) and neuroimaging techniques (i.e. fMRI & VLSM) to investigate the neural correlates of language, attention, and spatial cognition in both health young adults and patient population.

Daniela Sacchetti Daniela Sacchetti

Daniela earned a Master’s degree in Experimental Psychology at Seton Hall University and a Bachelor’s degree in Psychology at Rider University. Her graduate school training focused on behavioral neuroscience and her thesis work addressed the anatomical and behavioral correlates of spatial neglect, a post-stroke disorder which effects attention. Daniela’s research interests include neurorehabilitation and neurodegenerative disorders of aging; she is also interested in executive functions specifically attention and processing speed. At the LCNS, Daniela is responsible for the regulatory documentation and correspondence for all study protocols under the direction of Dr. Hamilton.  She is also involved in studies which explore the use of tDCS and TMS in patients suffering from Aphasia.

Research Specialist
Samuel Cason Samuel Cason

Sam graduated from the University of Delaware with a Bachelor’s degree in Cognitive Science and a Master’s degree in Linguistics. His responsibilities as a research specialist include managing regulatory documentation and correspondence for all study protocols under Dr. Coslett, He is involved in studies that use non-invasive brain stimulation to explore cognition, and a study that investigates the use of Virtual Reality as a treatment for Phantom Limb Pain. His research interests include the neural basis of cognition, specifically perception and language.

Laura DeLoretta Laura DeLoretta

Laura earned a Bachelor of Science in Psychology from the University of the Sciences in Philadelphia in May 2015.  Her responsibilities as a research assistant at the LCNS include using TMS to predict language recovery in people who have had strokes. Her research interests include investigating the efficacy of non-invasive brain stimulation as alternative treatment for psychiatric disorders.

Eric McConathey Eric McConathey

Eric graduated from Drexel University where he earned a Bachelor of Science degree in Psychology. After graduating, he continued to conduct research and analyze data in the Health and Sleep Psychology laboratory. He then moved on to a clinical research role at the Children’s Hospital of Philadelphia before joining the LCNS. Eric is currently involved in several noninvasive brain stimulation studies including a study investigating tDCS as a potential therapy for Primary Progressive Aphasia and another using network neuroscience to examine the effects of TMS on cognitive control in healthy participants. Eric is particularly interested in the use of non-invasive brain stimulation in neurorehabilitation and neurodegeneration.

Graduate Students Researchers

Catherine Norise Catherine Norise

Graduating from Haverford College in May 2011 majoring in Biology and minoring in Japanese. Cathy is currently a medical student at the Perelman School of Medicine at the University of Pennsylvania. She is analyzing the efficacy of TMS as a treatment for aphasia in stroke patients in our lab and evaluating a case study of an acquired deficit in audio-visual speech.
