Three postdoctoral positions in high-resolution retinal imaging: Three postdoctoral positions are available immediately in the ARIA imaging group at the University of Rochester, which includes William Merigan, Jennifer Hunter, David Williams and Mina Chung. A major emphasis of the ARIA laboratory is study of the function of inner and outer retina neurons in mouse and monkey using a variety of methods including calcium imaging with genetically encoded calcium indicators and single and multiphoton imaging of both intrinsic and externally applied fluorophores.
Position 1 - In vivo functional imaging of mouse and monkey retinal neurons. This position in the laboratory of Dr. William Merigan will use recently developed in vivo optogenetic methods to study retinal circuitry in the living mouse and macaque retina. It will provide excellent training for students experienced with traditional neurophysiological techniques who want to pursue in vivo optical methods, which provide a novel opportunity to study macaque foveal ganglion cells and to track long-term changes in the response of individual cells over many months. Experimental approaches used in the laboratory include fluorescence and reflectance adaptive optics imaging in mouse and macaque, optical coherence tomography, genetically encoded indicators and modulators of neural function and viral vectors. The ideal candidate will have a strong, quantitative background in visual science and retinal physiology, as well as experience with mathematical modeling/programming.
Position 2 - In vivo imaging of intrinsic fluorescence in mouse and monkey retina. This position in the laboratory of Dr. Jennifer Hunter will develop and apply novel fluorescence imaging methods for the non-invasive tracking of the role of both inner and outer retinal cells in the visual cycle. Research directions may include applying adaptive optics scanning laser ophthalmoscopy to phototoxicity, retinal development, aging or disease in mouse and macaque. Research in the Hunter laboratory emphasizes the development of single and multi-photon imaging techniques and their application to phototoxicity and retinal function. The ideal candidate will have a strong background in retinal biochemistry of metabolism and/or the visual cycle, as well as experience in general visual science and retinal physiology.
Position 3 - In vivo super resolution imaging of the retina. This position in the laboratory of Dr. David Williams will develop a new method for imaging the retina in the living eye at a resolution that surpasses the diffraction limit. The ideal candidate will have had prior experience with super resolution methods in microscopy, fluorescence imaging, and/or facility with the design and construction of advanced optical instrumentation for biological applications.
The University of Rochester offers a stimulating research environment and excellent opportunities for interactions and training in imaging and visual science including the Center for Visual Science, the Flaum Eye Institute and the Institute of Optics. ARIA, CVS and FEI provide access to a large technical staff including programmers and optical and electrical engineers focused on the development of novel imaging methodologies. Interested applicants should send CV and names/contact information of three references to . Please include a cover letter detailing your current research activities, expertise and the reasons for your interest in one of these positions.
Postdoctoral Positions in Visual Optics and Psychophysics: Postdoc positions are available to conduct studies in the field of visual optics and psychophysics in Geunyoung Yoon's Advanced Physiological Optics Laboratory at the University of Rochester Flaum Eye Institute.
Our previous work found evidence indicating that long-term visual deprivation caused by the eye’s optical defects gradually alters human visual processing. The objective of the project is to understand the limits of human vision by studying the relative contribution of optical and neural factors to neural processing of images formed by the optics of the eye. The project will use various advanced correction methods including adaptive optics vision simulator, customized ophthalmic lenses and corneal surgery that have been validated previously. The project is also expanded to presbyopia correction and binocular vision. The candidate will further be given opportunity to learn/be involved in other translational research in the laboratory including high-resolution corneal and anterior segment imaging, multimodal human tear imaging for dry eye research and corneal biomechanics.
The position is available immediately and applications will be considered until the position has been filled. Enthusiastic candidates with prior research experience in Optics and/or Visual Psychophysics are invited to apply and should be proficient in spoken and written English. Applications should include CV, one-page statement of research experience and interests, and contact details of three references. Please send application to Prof. Geunyoung Yoon ( ).

Postdoctoral Position in Visual Cognitive Neuroscience: Postdoctoral position to study cortical circuitry underlying memory-guided visual decision-making is available immediately in the laboratory of Dr. Tatiana Pasternak. Experimental approaches include extracellular single- and multi-electrode recordings of spiking and LFP activity from prefrontal and extrastriate cortical regions of non-human primates during visual comparison tasks. Other approaches include microstimulation and reversible inactivations. An important component of the work is a recently established collaboration involving computational modeling of mechanisms underlying maintenance and utilization of visual information in decision-making.
Preference will be given to candidates with strong quantitative background and experience in extracellular recordings in monkeys. However, applicants with strong background in related disciplines of systems and visual neuroscience are welcome to apply. Experience with MATLAB programming is highly desirable. Proficient knowledge of the English language is required.
The position is for at least two years. University of Rochester offers a stimulating research environment and excellent opportunities for interactions and training in cognitive neuroscience and visual science. Interested applicants should send a CV and names/contact information of three references to firstname.lastname@example.org . Please include a cover letter detailing your current research activities, expertise and the reasons for your interest in this position.
Postdoctoral Position: The Center for Visual Science (CVS) at the University of Rochester is seeking applicants for a post-doctoral training fellowship in visual science. CVS is an interdisciplinary center that brings together faculty from cognitive science, neuroscience, biomedical engineering, optics and computer science who are interested in a wide range of topics within vision science. The Center has broad areas of strength in computational modeling, psychophysics, neurophysiology and brain imaging. Faculty apply these approaches to topics including physiological optics, visual coding (e.g. of visual motion), 3D perception, the visual control of motor behavior and complex actions, visual attention, learning and memory, and visual development. Faculty and postdocs have access to numerous state-of-the-art technical resources including adaptive optics systems for correcting optical aberrations and imaging the human retina, several virtual reality systems, facilities for physiological recording in awake, behaving animals and a new 3-Tesla magnet devoted to fMRI research in brain and cognitive sciences. Interested applicants can find more information about CVS at http://www.cvs.rochester.edu. Applicants should include a CV, a statement of research interests and three letters of recommendation. The successful candidate will work with the selection committee to select an appropriate faculty mentor. Candidates are encouraged to contact faculty with whom they are interested in working to help prepare their application.
