Marcus Boehme

Dr Marcus Boehme is a Postdoctoral Researcher in the lab of Prof. John Cryan and Prof. Ted Dinan at APC Microbiome Ireland, University College Cork, Ireland. He completed his undergraduate training in Nutrition (Diploma) at the Friedrich-Schiller-University of Jena, Germany, where he investigated the impact of anti-inflammatory interventions on neurogenesis in the aged rodent brain under the supervision of Prof. Otto W. Witte (Department of Neurology, University Hospital Jena). He also worked in the lab of Prof. Michael Ristow (Experimental Nutritional Medicine, Institute of Nutrition, Friedrich-Schiller-University Jena) where he investigated the impact of low-level stressors on longevity in C. elegans.
Dr Boehme received his PhD from the Friedrich-Schiller-University of Jena, Germany where he studied the long-term consequences of sepsis on brain plasticity and behaviour across lifespan. His current research is focused on the impact of diet-microbiome interactions on neuroimmune signaling, behaviour and brain function across lifespan. He is the lead researcher on the Cork-led European-wide project AMBROSIAC, investigating the relationships between diet, stress and cognition across lifespan with a focus on the gut microbiota as a key mediator. Moreover, he is interested in the role of novel dietary interventions on the gut microbiome and their importance in early life, cognition, stress and aging.

Oleg Butovsky

Dr Butovsky’s major scientific objective is to understand the biology of microglia and its relationship to the peripheral innate immunity of the brain in both homeostasis and neurodegenerative conditions. He completed his Ph.D. at The Weizmann Institute of Sceince in Israel, focused on the role of microglia in neurogenesis and the regulation of plaque depositions in Alzheimer's Disease (AD) models. Dr. Butovsky has since established his own laboratory at the Brigham and Women’s Hospital in Boston, MA, USA and holds an Assistant Professorship at Harvard Medical School. He has led a series of investigations which have thus far revolutionized knowledge of the innate immune system in neurodegenerative conditions and opened up new opportunities for studying early-life developmental conditions relationship to cognitive disorder predisposition. In addition to homeostatic microglia, most recently Dr. Butovsky’s lab has redefined our classification of microglia both in mice and in humans in disease. These microglial appear to be a universal measure of the response of microglial to neural injury and are seen in multiple neurodegenerative diseases including MS, ALS and AD. Dr. Butovsky’s endeavors have led to the generation of robust novel tools including a series of microglia-specific mAbs, microglia culture techniques, and new mouse models. Dr. Butovsky has published several high-impact papers which received worldwide recognition and maintains numerous NIH awards and national and international collaborations focused on elucidating the role of microglia regulation in ALS, MS, and AD with the goal of identifying mechanisms which may one day target personalized immune-based therapies for patients with neurodegenerative conditions.

Pico Caroni

The Caroni lab investigates regulatory mechanisms that control the plasticity of identified subpopulations of synapses, neurons, neuronal microcircuits, and neuronal assemblies, and how this plasticity relates to learning, memory, and behavior. They are particularly interested in mechanisms that link circuit plasticity induced upon learning to consolidation and editing of memories, and in the contributions of specific cortical areas and hippocampal subdivisions to learning and memory.
Pico Caroni studied biochemistry at the ETH in Zurich, Switzerland. He is a groupleader at the Friedrich Miescher Institut for Biomedical Research in Basel, Switzerland, and a Professor of Neuroscience at the University of Basel.

Tim Oberlander

Dr. Tim Oberlander is a physician-scientist whose work “bridges” developmental neurosciences and community child health.  As a clinician he is the medical lead for the Complex Pain Service at BC Children’s Hospital with a particular focus managing pain in children with developmental disabilities.
As a researcher, Dr Oberlander’s work seeks to understand how early life experiences, related to in utero exposure to antidepressants, shape stress reactivity, cognition and attention during childhood that contribute to the early origins of self-regulation.
  His work provides strong evidence that both maternal mood and in utero selective serotonin reuptake inhibitor (SSRI) antidepressant exposure influences infant and childhood behavior, possibly via early changes in central serotonin signaling.  His work shows that the developing brain has a remarkable capacity for plasticity and recovery. 
His work is driven by curiosity and passion to know why even in the face of adversity, some children do very well and others have more difficulty with learning thinking and behavior. The goal of his work is to figure out how and why this happens.

She currently has no conflicts of interest to report.

Veit Stuphorn

Humans can flexibly control their behavior in response to internal and external demands. They can also voluntarily decide which action to take. My main research interests are the neuronal mechanisms that underlie behavioral control and decision making. I study these two important and interrelated functions by recording the activity of single neurons and local field potentials in awake, behaving monkeys. My first experience in electrophysiological recordings in monkeys was during my graduate work at the Ruhr-Universität Bochum in Germany. During my work as a postdoctoral fellow at Vanderbilt University, I begun to studying the role of the frontal cortex in response inhibition and evaluation. After I started my own independent laboratory at Johns Hopkins University in 2004, I continued to study behavioral control and decision making. I laid the groundwork for the proposed research by building up a primate electrophysiology laboratory with the techniques and expertise to record the simultaneous activity of multiple single neurons and local field potentials from multiple electrodes in behaving monkeys. Currently, my lab studies response inhibition, self-control, decisions under risk, and multi-attribute decision making.

Laura Trovó

Laura Trovó studied Biotechnologies in Italy and later obtained her PhD in molecular genetics from the Catholic University of Leuven (Belgium), where she studied the role of several membrane lipids in neuronal survival and function during ageing. She is currently a postdoctoral fellow at the Institute of Neuronal Cell Biology in Munich in the laboratory of Thomas Misgeld. Thanks to an EMBO long-term fellowship she applies her lipid-related training to evaluate axon-degenerative pathways. Furthermore, she has become increasingly interested in mitochondrial biology and in understanding how heterogeneous this organelle might be in the CNS.
