Dr. Greta Vargova grew up in Slovakia where she pursued her undergraduate studies in molecular biology and PhD in neuroscience. In her doctoral research at the Slovak Academy of Sciences, Dr. Vargova co-developed, applied and characterized several types of adeno-associated viral vectors expressing human truncated tau and red fluorophore mCherry in equal ratio. These AAV vectors were developed to induce Alzheimer’s disease-like pathology in wildtype mice. She performed two-photon calcium imaging in awake mice to investigate the effects of developing neurodegeneration on cortical circuits. Dr. Vargova also had the opportunity to participate in long-term research at Cold Spring Harbor Laboratory, where she studied the role of cortical feedback projections in sensory perception.
Currently, Dr. Vargova is a third year postdoctoral researcher at UCR Riverside in the laboratory of Professor Hongdian Yang. She studies somatosensory perception and cognitive flexibility, for which they have developed a novel, tactile based rule-shift behavioral assay.
For this webinar, she is going to present their most recent publication, in which they show the link between locus coeruleus activity and behavioral flexibility.

Dr. Junshi Wang is an enthusiastic neuroscientist who has been investigating neural mechanisms underlying drug addiction for 14 years. He earned his PhD in Neuroscience from Arizona State University, where he was mentored by Drs. Ron Hammer and Ella Nikulina. While there, he used behavioral models and immunohistochemistry to comprehensively investigate how brain-derived neurotrophic factor (BDNF) signaling in the brain reward circuit regulates stress-exacerbated addictive behaviors. In his first postdoc training period (2014-2020), in Dr. Yan Dong’s lab at the University of Pittsburgh, he learned electrophysiology. Since then, he has been using electrophysiology to study neuroplasticity in addiction. Currently he is a postdoc in Dr. Paul Kenny’s lab, at Mount Sinai School of Medicine. Dr. Wang enjoys making modifications to procedures and instruments to gain better control at each experimental step, ultimately leading to better-quality data.

Dr. Fordahl will highlight how proinflammatory cytokines alter dopamine terminal function, and how increasing dietary fat intake may enhance microglial activity. The Fordahl Lab’s primary research interests are to examine how the excessive intake of high fat or high sugar foods alter brain function, leading to dysregulated food intake. They are interested in how prolonged consumption of a palatable diet degrades the perception of natural rewards by altering dopamine signaling in response to food. Their lab pairs a pre-clinical rodent model of obesity with electrochemistry, immunochemistry, and other biological endpoints with behavioral markers of dopamine system function.
In this webinar, Dr. Fordahl will:

In his PhD in Molecular Biology, working with Ben Hankamer at the Institute for Molecular Bioscience, University of Queensland, Dr. Maurizio Chioccioli led a large-scale, high-throughput analysis to develop next generation microalgae systems for commercial (biofuels) applications. This work ignited his passion for quantitative imaging of dynamical systems, which he then pursued in a short postdoc at University of Cambridge, UK in the Department of Applied Mathematics and Theoretical Physics under Ray Goldstein. While there, Dr. Chioccioli invented a novel live video-microscopy platform and worked closely with mathematicians and physicists to study dynamic flagella beating and trajectory of single-cell C. reinhardtii. Turning to the biomedical field, in the lab of Pietro Cicuta at the Cavendish Laboratory at University of Cambridge, he applied these same modeling principles capture dynamic ciliary beating via high-speed video-microscopy. He co-invented new quantitative approaches to assess drug efficacy in Cystic Fibrosis patients and to characterize and potentially diagnose different variants of Primary Ciliary Dyskinesia. Dr. Chioccioli was recruited to Yale School of Medicine in 2018, where he is now Instructor under the mentorship of Naftali Kaminski in the Section for Pulmonary, Critical Care and Sleep Medicine. His appointment has provided him the intellectual freedom and independence to pursue research interests in alveolar injury and regeneration and specifically the role of AT2 cells in these processes. In his most significant body of work to date, he led a study to define the dynamic spatiotemporal coordination of alveolar stem cells in response to injury and discovered motility of these cells as a new cellular mechanism through which the alveolar injury response is coordinated.

Dr. Joseph Ransdell completed his undergraduate degree in Neuroscience at the University of Minnesota. He then completed his Ph.D. at the University of Missouri Columbia and studied the regulation of membrane excitability in crab motor neurons. After receiving his Ph.D., he joined the lab of Jeanne Nerbonne at Washington University. There, he continued using electrophysiological methods to test how ion channel accessory proteins regulate the excitability of various types of mouse central neurons. In 2020, Dr. Ransdell started his independent lab at Miami University in Oxford, OH. He continues to work with mouse models and his team has centered their focus on the regulation of voltage-gated sodium channels and the contributions of the channels to the functioning of cerebellar circuits during health and disease.
In this webinar, Dr. Ransdell explores how the Compresstome vibrating microtome is used to produce healthy brain slices for electrophysiology. He studies adult Purkinje neurons in mouse cerebellar brain slices.
