I am interested in how early life stress impacts the brain and behavior later in life. Using the zebrafish, I am establishing a model of early life stress and exploring its impact on neuroendocrine regulation, neurochemistry, and resultant impact on circuits and various behaviors such as sleep and feeding. I use a variety of behavioral assays, differential gene expression analysis to explore changes in stress-related genes and pathways, and whole-brain calcium recordings in awake behaving animals to examine neural circuits that have been altered.

I have a strong interest in doing research on neuroimmunology. My research aims to elucidate the mechanism how inflammatory activities affect the brain. Different from the current dogma that inflammation mediates mostly detrimental effects to the central nervous system, my discovery has unveiled beneficial influence of peripheral inflammation on the brain and many critical physiological functions of inflammatory mediators. During my PhD study, I have received broad training on immunology, neuroscience, behavioral science and molecular biology. My previous work focuses on the influence of IL-1 in the context of CNS inflammation. I have developed a very useful genetic mouse model and shared it with many labs across the world. I am currently working on different disease models for studying neurological disorders with an immunological etiology including experimental autoimmune encephalomyelitis and peripheral inflammation mediated affective disorders.

My research is focused on mapping neural activity and circuits in the evolutionary animal model, A. mexicanus. The Mexican blind cavefish have evolved differences in their behavior, morphology, and brain development relative to the ancestral surface-dwelling population. My main study uses transgenic cave and surface fish that express a calcium sensor in the brain (GCaMP). With these, we will record and analyze whole-brain activity during various stimuli in sleeping and awake fish in order to better understand their differences in behavior and brain activity.

My research study is on the neuroprotective and neurogenic effect of a growth factor, granulocyte-colony stimulating factor (G-CSF) in a mouse model of global ischemia. Using the adeno associate virus, I am transferring the recombinant human G-CSF (rhG-CSF) gene into the mouse brain and observing the efficacy of the expressed rhG-CSF protein at the cellular and molecular level. This work extends itself as a potential gene therapy for global ischemia. Read more about my research. Read more about my research.

I'm involved with multiple human neurodegenerative and neurobehavioral disorders mainly Stroke, Parkinson's disease and Alzheimer's Disease. My current research study focuses on the "Neuroprotection of GCSF Gene Therapy in Alzheimer's Disease (AD)". This research receives fund as postdoctoral award from the Ed and Ethel Moore Alzheimer's Disease Research Program. Using the DNA of GCSF into an Adeno Associate Virus -2 (AAV -2) - a technique known as gene therapy. AD is characterized by memory loss due to the degeneration or death of brain cells. We are transferring the recombinant human G-CSF (rhG-CSF) [which stimulates human bone marrow to make stem cells] gene into the transgenic mouse model of AD and observing the efficacy of the expressed rhG-CSF protein at the cellular and molecular level to see neuroprotective effect of gene therapy in AD.

I am using Astyanax mexicanus to study eye morphogenesis and brain development. A mexicanus exists in two forms, a sighted, surface-dwelling form and a blind, cave-dwelling form that initially develops small eyes that subsequently degenerate. Cavefish eyes display differences in shape during development relative to surface fish, allowing for the examination of the cellular mechanisms that underlie these differences. Further, cavefish brains are significantly different from surface fish brains, providing an opportunity to investigate the relationship between the developing eye and the developing brain. We use genome-editing and transgenesis techniques, combined with live imaging, to examine how the eye assumes its proper shape, how this affects the structure of the brain, and what occurs, at a cellular level, when the genes that underlie these process are modified. Because the process of eye morphogenesis is highly conserved between species, these studies will allow us to understand how structural defects occurring humans.

I study the underlying evolutionary, genetic and neural mechanisms that contribute to a diversity of behaviors and phenotypes, with a current focus on understanding sleep. Using this fruit fly, I have identified that the transporter Eaat2 functions in in ensheathing glia to modulate sleep, and developed a novel system to measure sleep depth via changes in metabolic rate in single flies. Further, I employ the blind Mexican cavefish Astyanax mexicanus, since this unique fish naturally evolved sleep loss, and I have developed transgenic cavefish to detect differences in brain activity during sleep state. Together, this research will help us to better understand mechanisms contributing to sleep disturbances and neurodiversity. Read more about my research.

My research focuses on the role of NOP (Nociceptin OPioid) and nicotinic receptors in migraine. Using a nitroglycerin mouse model of migraine I can effectively mimic symptoms observed in migraineurs. I am focusing on the evaluation of NOP and nicotinic ligands effects on parameters of sensory (sensitivity of paw) and affective (conditioned place avoidance) migraine pain as well as light aversion in mice. I am also interested in elucidating the function of these receptors in microglia system in trigeminal ganglion and trigeminal nucleus caudalis under acute and chronic migraine conditions. My two-year postdoctoral position at Dr. Toll’s lab is funded by the Polish Ministry of Science and Higher Education grant "Mobility Plus"(1662/1/MOB/V/17/2018/0).
