A postdoctoral position is available in the group of Ralf Haefner in the department for Brain & Cognitive Sciences at the University of Rochester (NY). The focus of our group is on understanding the neural basis of perceptual inference. Based on the assumption that the brain performs probabilistic inference using an internal model of the world, we ask questions such as: What is the nature of the internal model? How is it learnt? How are posterior beliefs represented by spiking responses of populations of neurons and what algorithm does the brain use to compute its beliefs? The position requires strong mathematical and good programming skills. The ideal candidate would also be familiar with (or quick to pick up) machine learning techniques, especially relating to probabilistic graphical models and MCMC sampling. Possible research projects range from purely theoretical to data-driven. Our collaborations with electrophysiology labs allow for the testing of theoretical models using state-of-the-art cortical population recordings in behaving animals and, if desired, the opportunity to record your own data. More information about past work is available here: http://tinyurl.com/rmhaefner and manuscripts indicating the group's research directions here http://arxiv.org/abs/1409.0257 and here: http://www.nature.com/doifinder/10.1038/nn.3309 For details on current and possible future projects, and general information, please contact me directly. The successful candidate with join a highly collaborative department with a strong tradition in probabilistic modeling across a wide range from sensory processing to language learning (https://www.bcs.rochester.edu/research/index.html ). The city of Rochester is located on the shore of Lake Ontario in upstate New York and has a high quality of life (http://en.wikipedia.org/wiki/Rochester,_New_York ). Start date and duration are flexible. Please send applications including a CV and names of 2-3 references by email. I'll be at COSYNE for both conference and workshops and available to meet there in person.
