Biography:
I received a B.A. in Psychobiology from Wellesley College and a Ph.D. in Neuroscience from U.C.S.D with a focus on behavioral pharmacology. I stayed in San Diego for my postdoc at The Scripps Research Institute, where I switched gears to learn molecular biology. My research is a natural extension of my training in both behavioral pharmacology and molecular biology, focusing on the generation and analysis of mouse models of movement disorders using both genetic and pharmacological approaches. Before joining the faculty at Emory University in 2008, I held academic appointments at Johns Hopkins University and Pennsylvania State University College of Medicine. I am currently a Professor in the Departments of Pharmacology and Neurology.
Research Interests:
Our research focuses on the genetic and neuropharmacologic underpinnings of complex behavioral disorders. We work on several different projects under this broad theme, including dystonia, Lesch-Nyhan disease, and channelopathies (episodic neurological disorders). The goal is to better understand and treat these neurological disorders by using a true bench to bedside approach.
Our group consists of basic science and clinical research components. We use a multi-disciplinary approach to determine the contribution of the basal ganglia and cerebellum to different disorders. We manipulate specific subpopulations of neurons using genetically engineered mice, viral vectors or drug challenges by targeting ion channels, receptors or neurotransmitters to cause or suppress dysfunction. We assess the effects of these manipulations on neuronal function and behavior to pinpoint the source of the dysfunctional signal. Our experiments have resulted in the development and characterization of several mouse models of human disease in our lab and in collaboration with others. This strategy provides a better understanding of the mechanisms underlying neurological dysfunction as well as the development of novel treatments.
Our clinical work is aimed primarily at translational research. This includes more precise characterizations of clinical phenotypes, exploring genotype-phenotype relationships, neuroimaging of the brain, biorepositories for exploring biomarkers of disease, and clinical trials of promising new treatments.

Biography:
I decided to become a career researcher when I learned that one could do something as fun as laboratory research full time and not just for a few hours a week as an undergraduate. I have worked in various fields of research ever since I obtained my degree in Molecular Genetics. In the Hess Lab, we utilize different methods, including genetic, pharmacological, and live imaging of neurons, to study mouse models of movement disorders, such as dystonia and PD. We are currently also investigating biological sex differences in dystonia. By understanding the disease mechanisms, in concert with data collected from our Drug Discovery Program, we hope to find a cure and/or treatment for patients with these debilitating illnesses.

Biography:
I graduated from Koc University School of Medicine in Istanbul, Turkey. During medical school I worked at Stem Cell Laboratory on iPSCs derived from patients with urea cycle disorder Citrullinemia type 1. I became interested in disease modelling and research in genetic and cell-based approaches to treat rare diseases. I am a Postdoctoral Research Fellow in the Hess-Jinnah lab. I investigate how development is disrupted in a monogenic neurodevelopmental disease during differentiation from iPSCs to mature neurons. My clinical interests include exploring the role of genomic medicine in improving health outcomes and I focus on understanding how genetic testing can be better utilized for the diagnosis of rare movement disorders. I am also a University Senate Representative for the Emory Postdoc Association and a member of Postdoctoral Council for Diversity. I enjoy swimming, hiking, and spending time in nature in my free time.

I am a medical doctor (MD) graduated from Tabriz University of Medical Sciences, Iran in 2018. I discovered my interest in science during basic science courses in medical school! During my time as a medical student I worked on multiple research projects. I studied effects of mitochondrial coenzymes on Multiple Sclerosis (MS) and then pursued a year-long thesis project in collaboration with University of Southern Denmark. There I worked on a quantification method to study age dependency of human brain metabolism using brain PET/CT. I also participated in two other multicenter epidemiologic studies aimed to discover serum biomarkers to predict stroke severity and outcome. To continue my interest in science, I am pursuing a PhD in neuroscience at Emory University and joined the Hess-Jinnah lab in 2019.
Under Dr. Jinnah’s supervision, I work with a novel model of induced pluripotent stem cells to study molecular pathogenesis of different neurological diseases including Lesch Nyhan disease, Parkinson’s disease, and dystonia. We have developed an in vitro model of midbrain dopaminergic neurons to discover the link between biochemistry of purine metabolism and neuronal development abnormalities. My daily work in lab starts with taking care of baby neurons developing in a dish!
Outside of work you can find me social dancing, playing tennis, practicing my favorite pieces in piano, and taking photos of the beautiful nature around Atlanta! I also love to discover US and travel around the world!

I am a third-year undergraduate at Emory University pursuing a major in Neuroscience and Behavioral Biology and a minor in Spanish. I’ve worked as a biology lab prep assistant for two years, and my favorite courses have been the lab sciences. In the Jinnah-Hess laboratory, I’m working as a research assistant for Dr. Jinnah to help explore the biochemical underpinnings of Lesch-Nyhan disease through neuronal cell culture, western blotting, biomolecular extraction, and more. My college experiences so far have helped solidify my aspiration to become a physician-scientist. In the future, I aim to be a positive force in patients’ lives by helping them cope with and recover from diseases while also undertaking research projects to uncover the biochemical mechanisms of neurological disorders and find effective treatments. In my free time, I love to play golf, watch movies, and spend time with friends and family.
