PhD position: Machine learning to record and enhance sleep and lucid dreaming
by Martin Dresler 03 Sep '20

03 Sep '20

Hi, Arenar B.V. and the Donders Institute offer a joint PhD position combining data science/AI and wearable EEG technology with sleep/dream research. In this project, the wearable sleep EEG headband iBand+ will be further developed and applied in several experimental studies. First, we will develop automatic sleep stage detection algorithms using machine learning strategies. We will then implement closed-loop acoustic stimulation procedures to enhance sleep slow oscillations to improve deep sleep. We will further develop combined acoustic and visual stimulation procedures which will allow to enhance self-awareness during sleep (i.e. lucid dreaming) and subsequent mood in the morning. The validity and efficacy of these procedures will be tested experimentally in large longitudinal studies in naturalistic home-based settings. The successful candidate will be centrally involved in the development, will lead different research projects within this general framework; will be closely involved in daily supervision of MSc students assisting the project; and will participate in the vibrant Donders Graduate School. Job details • 4 years at Donders, extension to permanent position at Arenar possible • Deadline: 31 August 2019 • Starting date: October/November, but somewhat flexible • Salary: starting with € 40000 gross per year Candidate profile • MSc-level background in Data Science, ML, AI, computer sciences, or adjacent field; • Proficiency in Python, C, C++, statistics • Interest in sleep, lucid dreaming, meditation • The capacity to participate in a collaborative, interdisciplinary, international research environment; • Fluency in written and spoken English. Candidates who only partially meet this profile are nonetheless strongly encouraged to apply! Organization The PhD project is a collaboration between Arenar B.V. and the Donders Institute. Arenar B.V. is a Dutch technology start-up based in Nijmegen, founded in 2016 by a team of engineers/developers with a combined technical industry experience exceeding 40 years working at leading technology companies such as NXP, Philips, Texas Instruments. Work in Arenar’s small enthusiastic team offers plenty of flexibility, responsibility and lots of influence on the product development.

DeepMath 2020: call for abstracts
by Kamesh Krishnamurthy 30 Jul '20

30 Jul '20

Dear all, We are now accepting abstract submissions to the 2020 Conference on the mathematical theory of deep neural networks (DeepMath). DeepMath is a highly interdisciplinary conference focused on understand fundamental theory driving the empirical success of Deep Learning. We are excited for this year's diverse set of invited speakers (see https://deepmath-conference.com for more information) and invite additional contributions from the community. Due to ongoing concerns about Covid-19, this year’s DeepMath conference will be conducted virtually. We are presently working on finalizing an online format that will seek to capture the small, community-focused experience of past DeepMath events. Important updates related to submission and registration are included below: == Submissions == We are still accepting submissions for virtual “posters” consisting of a pre-recorded talk and Q&A session. Similarly to last year, a selected number of top posters will be invited to present their work live as contributed talks. == Registration == Participation in the conference will require registration costing a nominal fee. We are working to keep costs as low as we can given the online nature of the event. As with last year, all talks will be live-streamed for free. More information on submissions can be found at the DeepMath website at https://deepmath-conference.com/submissions Warmest regards, The DeepMath Organizing Committee

Postdoctoral position to study the neural circuit of social behavior
by Hong, Weizhe 30 Jul '20

30 Jul '20

The Hong Lab at UCLA (hong-lab.com) is looking for a new postdoc to study the neural circuit of social behavior in mice. We are particularly interested in candidates with expertise in systems and/or computational neuroscience. Social interactions between individuals and among groups are a hallmark of human society as we know it and are critical to the physical and mental health of a wide variety of species including humans. Impairment of social function is a prominent feature of many neuropsychiatric disorders such as autism spectrum disorders and schizophrenia. Nonetheless, many fundamental questions regarding the neural mechanisms underlying social behavior remain unanswered. The central goal of Weizhe Hong’s laboratory is to study general principles of how social behavior is regulated in the brain. We take a multi-disciplinary approach and uses a variety of experimental and computational technologies across molecular, circuit, and behavioral levels. We are interested in how neural dynamics regulates social behavioral decisions within a single brain as well as how emergent inter-brain neural properties arise from social interactions between individuals.

PhD position in network neuroscience at University of Sussex
by Luc Berthouze 29 Jul '20

29 Jul '20

Applications are invited for a fully-funded PhD scholarship to undertake research in network neuroscience at the University of Sussex. A number of conditions, such as Parkinson’s Disease, are referred to as ‘oscillopathies’ because there is evidence that some of their major symptoms are underpinned by pathological synchronisation of neurons in key networks. A promising form of treatment is that of online control of deep brain stimulation based on computational processing of brain signals. Therefore, new mathematical insights about how to detect and efficiently disrupt pathological processes can be rapidly translated to patient benefit. Using models of oscillations on networks, this project will seek to investigate the conditions (either on the oscillators themselves, or the connectivity, or factors that may frustrate the interplay between dynamics on and dynamics of the network) under which pathological oscillations in one small area of the brain can intermittently or otherwise ‘infect’ the wider network of the brain causing the pathological symptoms. This project will involve an active collaboration with Dr Simon Farmer at University College London (UCL). This 3-year studentship includes student fees and a tax-free stipend starting at £15,285 per annum. It also comes with a generous Research Training Support Grant. Start date is flexible. Eligibility All nationalities are eligible to apply for this studentship. You should have a first-class honour degree or equivalent, or an MSc degree (preferably), in Computer Science, Mathematics or Physics (or relevant disciplines). You will have (and enjoy using) strong analytical skills as well as excellent programming skills in at least one of C++, Python, Matlab. Applicants interested in the post, seeking further information or feedback on their suitability are encouraged to contact me. All applications must be made via http://www.sussex.ac.uk/study/phd/apply where you will find details of entry requirements. Please clearly state on your application form that you are applying for 'Dynamics on/of networks and oscillopathies'. Luc Berthouze Professor of Complex Systems University of Sussex

We are particularly interested in individuals who have a demonstrated interest in computational psychiatry, developing models of human psychopathology, and collaborations with clinical groups focused on mental illness within the DIRP and broader research community. Research programs should focus on theory development but may also include experimental work that tests theoretical models. The unique investigator-based DIRP research support package encourages the development of a coherent, long time-horizon scientific program focused on generating deep insights into complex problems. Candidates must have earned a Ph.D. or M.D. and will have demonstrated experience as an outstanding independent investigator. An individual selected for the position is expected to build a dynamic and productive research laboratory, mentor and train scientists, and make use of the excellent opportunities for collaborative, translational, and high-risk/high-reward science available at the NIH.
