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.

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.

Christopher Haslam Christopher Haslam

Chris graduated from Temple University with a Bachelor of Science in Neuroscience. His responsibilities as a research specialist at the LCNS include investigating the effects of HD-tDCS and language therapy on individuals with Primary Progressive Aphasia. He also works on a study involving the effects of TMS on cognitive control and another involving the use of VR technology as a diagnostic tool for neglect. Chris’s research interests include investigating the cognitive basis of language through the scope of neurodegenerative disease.

Jonathan Magill Jonathan Magill

Jonathan graduated with a Bachelor of Arts in Psychology from the Pennsylvania State University in May 2016. He spent two years doing olfaction research at Monell Chemical Senses, and is interested in how TMS combined with speech therapy could help with the treatment of aphasia. His responsibilities at the LCNS include recruitment, and community outreach.

Graduate Students Researchers

Jared Zimmerman Jared Zimmerman

Jared is a graduate student in the Neuroscience Graduate Group at the University of Pennsylvania working under to co-mentorship of Drs. Roy Hamilton and John Medaglia.  Broadly, his research interests focus around novel methods in neuroimaging analysis and network neuroscience for precision mapping of functional brain systems in individual subjects.  He aims to combine these approaches with non-invasive brain stimulation to build towards a framework for leveraging neuroimaging data to guide brain-based interventions for disorders in neurology and psychiatry.  Towards this end, he also thinks it’s essential to develop a better understanding of how dynamic patterns of brain activity underlie the cognitive and affective processes that become dysfunctional in these disorders.  Prior to coming to Penn, he received a BSc in Neuroscience from Trinity College before working as a data analyst at the Massachusetts General Hospital and Martinos Center for Biomedical Imaging.
