Department of Neurobiology and Anatomy Postdoctoral Fellows & Research Associates

Guillaume Caron, PhD

Guillaume  Caron, PhD

gc483@drexel.edu

Education:
Dr. Caron completed his PhD at Aix-Marseille University, where he was investigating how the spinal network is altered by physical activity. He is now a post-doctoral fellow in the Côté lab.

Lab research:
The Côté lab is studying the plasticity of spinal networks after spinal cord injury. More precisely we focus on understanding how activity-based therapies contribute to functional recovery after spinal cord injury.

Research project:
Dr. Caron’s current project is to understand some of the mechanisms involved in spasticity and hyperreflexia after spinal cord injury. Physical rehabilitation and pharmacological treatment interacting with Chloride homeostasis are associated to improve functional recovery

Eileen Collyer, PhD

etc53@drexel.edu

Education:
Bachelor's in Biological Sciences from the P. Catholic University of Chile
PhD in biological sciences, subprogram in physiology from the P. Catholic University of Chile
Postdoc in Mark Tuszynski’s lab at University of California in San Diego

Research:
My interest in spinal cord injury started early on during my PhD and has become my ultimate long-term career goal to address translationally relevant questions in the field. Since then, my research has evolved from the study of the underlying contribution of Wallerian degeneration to collateral sprouting of motor axons after an SCI to evaluating the impact of rehabilitative training combined with neural stem cell transplantation on the locomotor function after a severe spinal cord injury. Currently, I am working on understanding the underlying mechanisms leading to the development of autonomic dysreflexia after an injury.

David Leonardo (Leo) Garcia Ramirez, PhD

dg679@drexel.edu

Education:
PhD in cellular and molecular biology at CINVESTAV of the National Polytechnic Institute (Mexico)
Bionic engineering at National Polytechnic Institute (Mexico)
Postdoctoral fellow in Kimberly Dougherty’s Lab in the Department of Neurobiology and Anatomy at Drexel University College of Medicine

Research interest:
Plasticity of the spinal locomotor circuitry after spinal cord injury and rehabilitation therapies.

Research overview:
My current research in Kimberly Dougherty Lab is focusing in the plasticity of rhythm generating interneurons after spinal cord injury and after therapies including treadmill training and epidural stimulation. My particular interest is to understand the serotonergic modulation and sensory afferent inputs to rhythm generating interneurons, the plastic changes following spinal cord injury and therapies to enhance locomotor. My research involves electrophysiological and behavioral techniques to determine plastic changes after spinal cord injury and rehabilitation therapies.

Marisa Jeffries , PhD

Marisa Jeffries: Department of Neurobiology & Anatomy

maj359@drexel.edu

Education:
BA in studio art, University of Virginia
BS in biology, University of Virginia
MS in neurobiology, University of Pittsburgh
PhD in biomedical sciences, subprogram in cell biology, neuroscience, and physiology, Rutgers University

Research overview:
I have been interested in spinal cord injury research since high school, when I attended a seminar series presented by The Miami Project. As a PhD student, I studied ERK1/2 and mTOR signaling in oligodendrocytes during myelin maintenance and remyelination of the adult brain and spinal cord. For my postdoctoral training in Dr. Veronica Tom’s lab, I am particularly interested in the neuroimmune component of autonomic dysreflexia after spinal cord injury.

Tae Gyo Kim, PhD

tk67@drexel.edu

Tae Gyo is a postdoctoral fellow in Dr. Giszter's lab.

Jun Liu, PhD

Jun Liu, PhD

jl3933@drexel.edu

Jun Liu, PhD, is a postdoctoral researcher in the Department of Neurobiology & Anatomy at Drexel University College of Medicine. He has worked in the lab of Dong Wang, PhD, since October 2017.

Research interests:
Neural ensemble dynamics underlying learning and memory; fear and anxiety; optogenetics; imaging.

Research overview:
The hippocampal/parahippocampal region and the amygdala nuclei play a pivotal role in emotion, learning and memory. These related brain circuits are also involved in mnemonic dysfunctions associated with neuropsychiatric and neurological diseases, such as posttraumatic stress disorder (PTSD) and excessive anxiety. Dr. Liu is interested in understanding the underlying neural ensemble dynamics at circuit level by using multidisciplinary and integrated experimental approach in mice, including in vivo electrophysiology, optogenetics, imaging, physiological markers, and behavioral techniques.

Emanuela Piermarini, PhD

Emanuela Piermarini, PhD

ep477@drexel.edu

Emanuela earned her PhD in biochemistry and molecular biology at University of Rome “Tor Vergata” in November 2016. During her PhD training she studied the role of oxidative stress in neurodegeneration, focusing her attention on the role of glutathione in the pathogenesis of Friedreich’s ataxia. She joined the Baas Lab as a postdoc in December 2016, where she is involved in the project of characterizing a new mouse model of hereditary spastic paraplegia.

Victor Rovira Zambrana, PhD

Victor Rovira Zambrana, PhD

vr354@drexel.edu

After graduating from the Universidad Miguel Hernandez in Spain, Victor obtained his PhD at the Instituto de Neurociencias de Alicante (Spain), studying interhemispheric cortical communication through the corpus callosum and the generation and modulation of oscillatory activity in the cingulate cortex. He is now a researcher in Dr. Detloff's lab, where he is studying the changes in the nociceptive neurons located in the DRG after spinal cord injury, both with or without rehabilitative exercise strategies after injury.
