2 Post-doc positions on the relation of information and causation (Prof. Giulio Tononi)
by Larissa Albantakis Dec. 17, 2014

Dec. 17, 2014

Up to 2 postdoctoral positions are available at the center for sleep and consciousness science in the laboratory of Dr. Giulio Tononi (University of Wisconsin, Madison), to study the relation of information and causation within the framework of the integrated information theory of consciousness (Balduzzi & Tononi, 2008; Tononi, 2012). Immediate funding is available for a range of projects related to foundational questions regarding the ontological status of information, and its relation to causation, emergence, adaptation, evolution, and consciousness (see detailed scope of work below). Successful candidates will work at the center for sleep and consciousness science, dedicated to a broad range of research problems focused on two neurobiological problems -- the mechanisms and functions of sleep and the neural substrates of consciousness. Candidates are expected to have strong training in an analytically rigorous discipline such as theoretical biology/neuroscience, physics, mathematics, computer science, or engineering. For at least one of the positions, we explicitely encourage mathematicians to apply. Experience in information theory, complex systems, and an interest in the philosophy of information/causation are a plus. Programming experience is required (knowledge of MATLAB and/or C++ is of advantage). Appointments are renewable from year to year for up to 3 years, starting as soon as possible or until the positions are filled. Post-doc salaries correspond to the National Institutes of Health National Research Service Award (NRSA) stipend schedule for postdoc trainees, based on number of years of postdoctoral experience. Candidates should send a CV, brief statement of previous research and future research interests, and email addresses and phone numbers of three references to: Giulio Tononi, gtononi(a)wisc.edu. Balduzzi D, Tononi G (2008) Integrated information in discrete dynamical systems: motivation and theoretical framework. /PLoS Comput Biol/ 4:e1000091. Hoel, E. P., Albantakis, L., & Tononi, G. (2013). Quantifying causal emergence shows that macro can beat micro. /PNAS/, /110/(49), 19790--19795. Tononi G (2012) Integrated Information Theory of Consciousness: An Updated Account. /Arch Ital Biol/ 150:56--90. The scope of work will range from: -theoretical development and computational implementation of the notion of intrinsic causal information -causal analysis, including the systematic use of perturbations, counterfactuals, and irreducibility -analysis of complex systems in terms their causal/informational structure -meaning (understanding and control) from the intrinsic perspective of the system -actual causation (causal explanation) -examining similarities and differences between existing notions of information and causation (Shannon information, algorithmic information,...) -defining emergence in terms of the spatio-temporal grain size at which a system of elements achieves a maximum of causal power -evolutionary/adaptive aspects of information/causation including simulations based on small adaptive neural networks (animats), which evolve and adapt to an environment that requires sensitivity to context for survival

Postdoctoral position at MIT/Janelia Farm
by Sam Gershman June 29, 2014

June 29, 2014

The labs of Alla Karpova (HHMI/Janelia Farm), Josh Tenenbaum (MIT) and Sam Gershman (MIT/Harvard) are seeking a postdoctoral fellow to work on a collaborative project studying neural implementation of internal models of the environment in rat medial prefrontal cortex. The goal is to understand the role of prefrontal cortex in inferring the general structure of tasks in hierarchically structured, dynamically changing environments, and the process by which this inference is used to optimize behavior. The fellow will be closely involved in the design of experiments and data analysis, including the development of new behavioral and neural analysis techniques. This position will give the successful candidate an opportunity to develop broad expertise in computational neuroscience, ranging from models of probabilistic inference at behavioral level to decoding behaviorally-relevant parameters from circuit dynamics. The fellow will be based at MIT, but will also spend time at Janelia Farm. Funding is available for 3 years, beginning immediately. We are looking for candidates with a strong mathematical and computational background, ideally with experience in both theoretical neuroscience and probabilistic modeling. Candidates with experimental training in neurophysiology who are interested in developing their computational skills are also encouraged to apply. For more information, please contact Sam Gershman (sjgershm(a)mit.edu) along with a CV and brief cover letter.
