Post-Doctoral Fellow

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.

 

Priyanka P. Shah

Priyanka P. Shah
Priyanka is a post-doctoral fellow in the LCNS at the University of Pennsylvania. She graduated in 2012 from a joint biomedical engineering program at the University of Medicine and Dentistry of New Jersey and the New Jersey Institute of Technology. During her graduate training, she worked with Drs. A.M. Barrett, Peii Chen, Kelly Goedert and Paola Fortis on developing a home-based intervention program for stroke survivors with spatial neglect. This program involved subjects training with either right-shifting prism goggles or neutral goggles as they performed ecological activities requiring hand-eye coordination; subjects trained at home under caregiver supervision. She demonstrated that subjects with motor-related spatial deficits, rather than isolated perceptual spatial deficits, benefitted from the home-based program. This finding emphasizes categorization of neglect subjects by their constituent cognitive deficits before evaluating benefits of interventions targeting spatial neglect. Her current research interests involve using the non-invasive brain stimulation techniques (i.e., tDCS and TMS) for the categorization and treatment of spatial neglect, and to understand the mechanisms underlying spatial cognition in healthy individuals.

Research Staff

Clinical Coordinator
Olufunsho K. Faseyitan

Olufunsho K. Faseyitan
Olu is 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 Specialists
Felix Gervits

Felix Gervits
Felix is a Research Specialist in the LCNS at the University of Pennsylvania. He earned a Master's degree in Linguistics and Cognitive Science at the University of Delaware, and, prior to that, a Bachelor's degree in Cognitive Science from Rensselaer Polytechnic Institute. His main interests including brain-computer interface, language acquisition and artificial intelligence. Other interests include volitional motor control, self-awareness, consciousness and the lofty goal of modeling all these phenomena in a cognitive architecture. Felix would like to pursue these areas of research using neuroimaging and brain stimulation techniques such as TMS, tDCS, fMRI and EEG.

Juliann Purcell
Juliann earned a Bachelor of Arts in Psychology from Gettysburg College and a Maser of Science in Clinical Neuroscience from University College London. At the LCNS, she is responsible for the regulatory correspondence and documentation of all protocols for which Dr. Coslett is the Principle Investigator. Juliann is interested in cognition and in using non-invasive techniques (such as TMS and fMRI) to elucidate the neural structures underlying cognition.

Medical Student Researcher
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.

 

Undergraduate Researcher
Jay Gill

Jay Gill
Jay is an undergraduate student at Penn majoring in Cognitive Science and minoring in Computer Science. He is currently working on a project that will apply tDCS as a therapy for multiple sclerosis patients.




TMS Scheduling Coordinator
Caitlin Breslin

Caitlin Breslin
Cait is a sophomore in the College of Arts and Sciences at Penn, studying the Biological Basis of Behavior and minoring in Hispanic Studies. She is interested in different non-invasive neural stimulation techniques like TMS and tDCS, and is particularly fascinated by aphasia. After graduation, she plans to take a few years to do full-time research and/or "find herself" before attending medical school.
