Arlene George, Neuroscience Institute Graduate Student

Arlene received her B.S. in Cellular and Molecular Neuroscience with a minor in Psychology at Temple University in 2013. As an undergraduate, she conducted research with Dr. Prasun Datta where she investigated the mechanism of how the manipulation of the glutamate transporter, EAAT2, causes excitotoxicity in astrocytes. Upon graduation, Arlene worked as a research technician at the University of Georgia in Dr. Rick Tarleton's lab.  There she investigated the role of Trypanosoma cruzi in Chagas disease where she determined the efficacy of novel trypanocidal compounds and implemented the CRISPR-Cas9 system to identify targets of drug action into trypanosomal organisms. Currently, Arlene is developing mouse models to understand the role of RNF216 in Gordon Holmes cerebellar ataxia.  Link

Joseph Sexton, summer ION student

Joseph is a junior at West Forsyth High School. His research interests are related to depression and serotonin-related conditions.  He is interested in developing a novel diagnostic for depression to someday give schools and healthcare professionals better tools to detect suicidal ideation.  His recent work, titled “Investigating the Relationship Between Psychiatric Conditions of 5-HT Malfunction and the Orbitofrontal Cortex (OFC) as Indicated by Reversal Learning Tasks”, has been accepted with revisions for publication at Harvard’s Journal of Emerging Investigators, and won high honors at the Georgia Science and Engineering Fair including 2nd place in Behavioral Sciences and a scholarship to the University of Georgia should he choose to attend. He was a finalist in the Atlanta Regional Brain Bee, ultimately finding neuroscience as his true passion. He has received leadership awards for his role as cross country and track captain since sophomore year, also qualifying as a five-time varsity letter-winner and two-time state qualifier. He was recently chosen for the “Most Positive Cross Country Athlete: North Atlanta” award based on his school involvement and “servant leader” outlook; he is also involved with Mu Alpha Theta, Science National Honors Society, the Principal’s Student Council, Slam Poetry Club, Science Fair, and founded a Condition Awareness Club where he leads students in presenting their diagnoses to other students, turning difficulties into opportunities for raising awareness. 

Wei Wei, Postdoctoral Fellow

Wei Wei received her Ph.D. degree in Immunology from South Medical University, China in 2013 where her project was focused on dysfunctional presynaptic regulation of striatal medium spiny neurons in mouse models of Parkinson’s disease. She then became a Postdoctoral Fellow in the department of Physiology at the University of Tennessee working on neural mechanisms driving food intake in the obese. She was particularly focused on how diet and body weight affect excitability of neuron populations responsible for food intake. With Dr. Mabb and Dr. Petrulis, she integrates in vivo Ca2+ imaging, electrophysiology and optogenetic techniques to understand pathways associated with neurological and social dysfunction.

Bailey Cottrill, Neuroscience Postbac

Bailey received her B.S. in Neuroscience at Georgia State University in 2018. She was an honors student and a member of the Nu Rho Psi honor society. Bailey is interested in molecular neuroscience and eventually wants to run her own lab. Currently, she is working on identifying brain-specific substrates for E3 ubiquitin ligases associated with neurological disorders. She is focusing on Nedd4, an E3 that is disrupted in schizophrenia and epilepsy. In her free time, Bailey loves to paint, hike, and volunteer with Children’s Healthcare of Atlanta.  Link

Mohammad (Amin) Ghane, Neuroscience Institute Graduate Student

​Amin graduated from the University of Illinois at Urbana-Champaign in 2015 with a B.S. in Molecular and Cellular Biology. He began his research in neuroscience as a member of the laboratory of Dr. Joshua Gulley, where his undergraduate thesis used biochemical and behavioral techniques to elucidate the mechanisms by which a bioactive metabolite contributed to the amelioration of age-related deficits in learning and memory. Following graduation, Amin spent two years as a research technician for Dr. Catherine Christian. There, he used techniques such as in vivo optogenetics, chemogenetics, and EEG to study astrocytic modulation of seizure susceptibility; explored mechanisms of neuroendocrine dysfunction in a model of temporal lobe epilepsy; and helped to characterize altered behavior and neurotransmission in a mouse strain lacking a key neuropeptide. With Dr. Mabb, he intends to use cutting-edge in vivo neuroimaging techniques to study the role of ubiquitin-mediated immediate early gene turnover in learning and memory related tasks.  Link

Fernanda Tallard, Neuroscience Postbac

Fernanda received her B.S. in Neuroscience in 2017.  Her major hobby is computer graphics.  Fernanda’s motivation to enter the field of neuroscience began in high school when she was tasked to study Alzheimer’s disease for an entire year and teach it to her class.  This sparked her love for neuroscience and inspired her to pursue research in neurological diseases.  Her project in the lab is focused on finding links between ubiquitin pathway disruption and its contributions to Alzheimer’s disease.  Fernanda is interested in causative factors of neurological disease and would like to contribute to finding a cure.  She plans to attend graduate school in the field of Clinical Neuroscience.  She also aspires to run her own lab and be a leading scientist trying to find clues to the mysteries of neurological diseases.
