Braulio Munoz is a Chilean native, who got his bachelor’s degree in Biochemistry from the University of Concepcion in Chile. He received his doctorate in Cellular and Molecular Biology from the University of Concepcion in Chile in 2016. Then, he moved to the USA to complete the postdoctoral training in the laboratory of Dr. Brady Atwood at Indiana University School of Medicine. Currently, Dr. Munoz is an Assistant Research Professor in Dr. Brady Atwood’s laboratory in the Department of Pharmacology and Toxicology at Indiana University School of Medicine, with a specific focus on studying glutamatergic and inhibitory (GABA, glycine) synaptic plasticity within corticostriatal neurocircuits. Dr.Munoz's personal life, he is a father of three amazing girls, he loves Star Wars, Lego playsets, also he enjoys cooking, grunge music, playing videogames with his daughters and spending outdoor time biking, hiking and fishing with his wonderful wife and fantastic daughters.

  • Research

    The effects of ethanol on the brain have led my interest in the neurophysiological mechanisms of ethanol; first, in glycine receptors and currently in excitatory and inhibitory synaptic plasticity. I have a strong background in the study of inhibitory neurotransmitter receptors from my graduate training in Dr. Luis Aguayo’s lab in Chile. In addition, I acquired expertise during my postdoctoral training in Dr. Atwood’s laboratory on mu opioid-mediated and cannabinoid-mediated glutamatergic plasticity, resulting in a number of different significant publications including one first-author publication in Nature Communications. My mentors provided me with a broad skill set in brain slice electrophysiology, optogenetic manipulations of neural circuits, stereotaxic surgeries to infuse AAV viral vectors and implant optic probes, the use of transgenic mice, and the study of G protein-coupled receptor signaling mechanisms, inhibitory and excitatory transmission, and synaptic plasticity. Also, during my time as a graduate, postdoctoral and now as a Research Professor, I have mentored numerous laboratory students (undergraduates and graduates), technicians and postdoctoral trainees in electrophysiological techniques, stereotaxic surgery and biochemistry methods.
