Postdoctoral Researcher

Basic and Applied Research on Human Binocular Eye Movements

The Smith-Kettlewell Eye Research Institute seeks a motivated and enthusiastic postdoctoral researcher to join the research projects in the Visuomotor Laboratory of Dr. Arvind Chandna, MD. Our main aim in this work is to investigate mechanisms of human binocular eye movements and accommodation with a special emphasis on clinical conditions (e.g. strabismus). A significant proportion of the ongoing research will be conducted under a joint mentorship with Dr. Steve Heinen, Ph.D.

The oculomotor system is usually studied by recording from one eye, assuming that a single command drives both eyes symmetrically, and also causally modulates accommodation, also driven by a unitary command. However, while normal control is thought symmetric, strabismus is asymmetric, with one eye dominating ocular control. In addition, while accommodation dysfunction is often implicated in childhood strabismus it is rarely measured in both eyes.

Our laboratory simultaneously records binocular eye movements and accommodation to elucidate normal and disordered oculomotor and accommodation mechanisms using innovative naturalistic environments and methodology with a view toward translating the results into clinical practice.

Eye tracking is a central focus at Smith-Kettlewell, and the Institute has available multiple binocular EyeLink 1000s, a PlusOptix PowerRefractor to measure accommodation, two SLOs, and other head-mounted (SMI, Arrington) and head-free (TobiiPro Pupil) trackers.

The successful applicant will be involved in one or more of the current ongoing projects in the Visuomotor Laboratory. The position requires a Ph.D. and is normally for two years. Strong programming skills are a plus, with experience in Matlab and/or eye movement recording and analysis skills especially desirable. Writing papers and assisting in grant applications will be part of this position. A background in clinical research will be an advantage. Successful postdoctoral researchers are often encouraged to continue at Smith-Kettlewell as sponsored investigators.

There is also exposure and possible eventual participation in current projects in ongoing work on mechanisms of normal and abnormal vision in adults and children with special emphasis on strabismus, amblyopia cerebral visual impairment, acquired brain injury with visual electrophysiology/EEG methods.


Candidates should have, or be close to completing, a Ph.D. in oculomotor neurophysiology, ocular motility and accommodation or a related area.

Strong skills should be demonstrable in:

  • Programming, especially MATLAB
  • Eye movement recording and analysis
  • Quantitative data analysis
  • Statistical methods

Desirable skills depending on the project, include experience with:

  • Psychophysics and behavioral measures
  • A clinical background will be helpful

The Smith-Kettlewell Eye Research Institute is home to a number of NIH-funded investigators with specialties that include visual psychophysics, oculomotor physiology, visual system fMRI and EEG and artificial computer vision. Collaborations between labs is frequent and encouraged. We are located in San Francisco, a hub of biomedical and biotech research with cultural amenities that include diverse dining and entertainment venues, and easy access to outdoor activities in many parks and waterways. Our location and reputation in vision science affords the opportunity for postdocs to collaborate with nearby universities and tech companies.

The position is exempt, full-time, 5 days per week (100% effort) with full benefits.  Our generous benefits package includes medical, dental, vision, life insurance, flexible spending accounts, commuter and pension plan.
