Hello, Welcome to Okinawa ! This is my 3rd year as postdoc in Doya Unit at OIST. I am a computer science guy, I did my master and PhD on data mining and machine learning on social networks, mainly using unsupervised learning models. At OIST, I learned about neural dynamics, ran several simulations of interacting populations on HPC using NEST, reduced the dimensionality of huge Spiking Network Models by using community detection and mean field models. Currently, applying unsupervised models and neural networks to segment tracer signal from brain images and performing parameters fitting for global tracktography on DWI data.
Expertise:
python, nest, machine learning, data mining, mean field approximation.
Espen Hagen (University of Oslo, Norway)
espe.hage[at]fys.uio.no
I am at present a PostDoc at CINPLA.ORG in Oslo, Norway. I have been involved in several modeling projects relating neuronal activity to extracellular potentials in neural tissue (e.g., spikes and local field potentials). One key component of these studies is multicompartment models combined with an electrostatic forward model. For this purpose, I’m involved in the development of LFPy (LFPy.github.io), a tool for computing such extracellular potentials in Python. One goal of such modeling efforts is aiding the interpretation of these nontrivial signals measured in the brain.
Expertise:
I am a regular user of point neuron network models, multicompartment neuron models, electrostatic forward models and high-performance computing (HPC) facilities.

I have expertise in detailed modeling of neurons with ion channels and intracellular ion dynamics, mainly in the NEURON platform. I also have some experience in developing data analysis techniques by using various statistical modeling frameworks such as LN model, compressive sensing, spectral clustering, and so on. The brain region that I am mostly familiar with is the cerebellar cortex. About computational tools, I write my simulations mostly in NEURON, and do my data analysis in Python and Matlab.

Expertise:
Throughout my research, I have learnt specialized techniques in retinal electrophysiology and device fabrication. I am proficient in techniques such as patch clamp, calcium imaging and photolithography, which allows me to create micron scale electronic devices on glass for the use in wet-lab experiments. As an electrical engineer, I have been able use my skills in programming, electronics, signal processing and control theory to devise experiments that help answer key questions about electrical stimulation of neural tissue. I have used tools in machine learning and statistical modelling to develop mathematical models that can be used to predict how neurons respond to electrical stimulation. The models I develop can be used to create more functional and smarter stimulation devices that can auto-regulate the amount of stimulation applied based on responses from individual cells.

I am a postdoc in Ishii Lab at Kyoto University, where I am interested in statistical approaches to connectome of the brain. I got a PhD at Institute of Statistical Mathematics to develop the method for analyzing dynamical system. Based on this experience, I proposed a dynamic Bayesian approach to estimate the glia-neuronal network using Ca2+ imaging data. My current work is to identifying global network structure obtained by Diffusion MRI and Two-photon microscopy to reveal the connectome of the marmoset brain. I’m looking forward to discussing with students in this OCNC.

Merav Stern (University of Washington, Seattle, USA)
merav.stern[at]mail.huji.ac.il
I grew up in a small town outside of Tel Aviv. My first tutor-like experience was in my teenage years as a figure skating instructor. Scientifically, I grew up at the Hebrew University, where I graduated with a Bachelor in Math and Physics, Master in Theoretical Physics and PhD in Computational Neuroscience. I also saw the world, I took my classes for my Master in Amsterdam, where I lived for a year, and did part of my PhD research in Columbia university in NY where I lived for three years. Currently, I'm a Postdoc at the University of Washington in Seattle.

Expertise:
During my PhD I improved our tools for studying non linear neural network dynamics. Specifically, I explored static and dynamic mean field solutions of rate neural networks that include strong self coupled units, and networks that include sub-groups of connectivity rules - a study which lead to new results in random matrix theory. In addition I have constructed a model for the pirifom cortex which captures its basic circuit properties and succeeds in explaining how concentration-dependent, temporal odor responses in the olfactory bulb are transformed into a concentration-invariant neuronal ensemble identity code. I also developed models for the olivo-cerebellar loop. Currently, I study different aspects of learning, in both models and recordings. Specifically, I seek to identify brain areas that alter their activity during the course of learning a visually-guided behavioral task and characterize these changes.
Marcel Stimberg (UPMC, Paris, France)

I am a research software engineer in the group of Romain Brette at the Vision Institute in Paris, France. My PhD in Klaus Obermayer's group at the TU Berlin, Germany, as well has my time as a PostDoc in Romain's group was about computational modelling, more specifically about small-size networks in the visual and auditory system. In recent years, my focus has shifted somewhat away from modelling towards the development of (open-source) software tools for computational neuroscience. Most importantly, I've been leading the development of Brian 2, your friendly simulator for spiking neural networks.

I am a postdoc at UCL working with Prof. Angus Silver. I am interested in the mechanisms underlying dendritic computations. My current experimental work is focused on how different network states shape dendritic integration in space and time. I am also carrying out 3D imaging of dendritic spine activity in mice that are performing visual tasks to gain a better understanding of dendritic computations in vivo. I am very excited about the OCNC because it will strengthen my abilities to think about, conduct, and analyze experiments in a multidisciplinary manner. My goal for the course is to explore the input/output relationship of individual dendritic branches with an emphasis on background synaptic conductance, distributed vs clustered excitatory synaptic inputs, and compartmentalized inhibition. The more I learn about computational neuroscience, the more I appreciate how a unique synergy is achieved when experimental and computational neuroscience are appropriately combined to study brain function. I look forward to meeting everyone in Okinawa and learning more about computational neuroscience!
