Miss Irma Gvilia is an internationally published Georgian neuroscientist, community leader, and dedicated patriot of her country. She enjoys balancing her professional and personal life between being a woman in STEM, a mother, a globe-trotter, and a gym enthusiast.
Her professional career spans over 25 years and 4 continents and, in addition to medical research, has seen her organize 10 international symposiums across 7 countries, teach and mentor students at the post-graduate level, and work in a government advisory committee on national education reform. Throughout her time as Professor of Neurophysiology at Ilia State University in Tbilisi, a Principal Investigator at VAGLAH, and UCLA’s David Geffen School of Medicine, Dr. Gvilia has maintained contacts and active collaboration with colleagues worldwide. She is a recipient of highly prestigious fellowships and awards from European and American research organizations. Yet, out of all these accomplishments, she is most proud of her two girls.
Dr. Gvilia was born and raised in the Republic of Georgia, a heritage she is immensely proud of. She completed her joint bachelor’s and master’s degree in Biology with Honors at Tbilisi State University in 1991 and her Ph.D. in Biology at Beritashvili Institute of Physiology in 1995.
Dr. Gvilia’s professional field and passion for patriotism crossed paths in 2013, when she led an exemplary professional conference in Kazbegi, Georgia – the first of its kind in the country – where she made sure that the 85+ participants from 23 countries spent most of their leisure time celebrating the rich culture, cuisine and beauty of Georgia. After a wonderful 6 days, they all left finally realizing what their Georgian colleague had been ranting about all these years.
The long-term goals of my research program are to identify and characterize, at the systems level, cell types, anatomical connectivity and neurochemical mechanisms that function to regulate sleep, and to recognize neuro-regulatory control points in these systems that might underlie sleep disturbance in psychiatric and neurological disorders during both childhood/adolescence and adulthood.
One of my current research work directions is focused on a fundamental unanswered question in sleep neurobiology – what brain mechanisms govern the development of sleep homeostasis? This knowledge is critical for identifying the causes of and developing strategies to treat sleep dysregulation in childhood and adolescence, a growing public health problem that has adverse effects on mood, cognition, social behavior, and physical health.
The other topic, which I currently lead, is directed towards determining fundamental mechanisms and circuits that might underlie the negative impact of stress-related release of corticotropin releasing factor (CRF) on the homeostatic regulation of sleep, with the goal of identifying critical regulatory nodes that can be targeted for therapy. Insomnia and insufficient sleep are common in psychiatric disorders that are associated with and/or exacerbated by physiological or psychological stress. Chronic sleep disturbance can contribute to maladaptive stress and may be a modifiable risk factor for poor psychiatric outcomes in PTSD, depression and other disorders.
Overall Contribution to Science: (1) Provided the first evidence that the population of median preoptic nucleus neurons, which is activated during sleep, is different from neurons activated in response to osmotic and hormonal stimuli; (2) Provided the first evidence that a subset of preoptic area neurons constitutes part of the forebrain circuitry involved in the homeostatic regulation of REM sleep; (3) Provided the first evidence that GABAergic sleep-regulatory neurons in the preoptic hypothalamus area involved in the regulation of sleep homeostasis.
Contribution to Science: (4) Provided the first evidence that early post-weaning in the rat is characterized by significant maturational changes in the homeostatic sleep regulation, and these changes are associated with functional emergence of the Hypothalamic sleep-regulatory neuronal systems. (5) Provided the first evidence on a potential mechanistic role of adenosine signaling in the brain and related activation of key sleep-regulatory neuronal groups (identified in the adult brain) in normal development of sleep homeostasis.
Significance the last publication (Gvilia et al 2017) has been acknowledged by The American Physiological Society Award – it is selected among the best recently published articles in physiological society (http://apsselect.physiology.org/).
Contribution to Science: (6) Provided the first evidence on the negative effect of stress-induced increases in CRF signaling in the brain on (i) the homeostatic regulation of sleep and (ii) the activity of sleep-promoting neurons in the MnPO and VLPO.
