Portrait of Vision Scientist: Jun Yang


Jun Yang‘s lab focuses on the molecular mechanisms of hereditary retinal degenerative diseases, focusing specifically on the mechanisms of a set of inherited diseases in Usher Syndrome where people go blind and deaf due to defects in the cytoskeleton of photoreceptors in the eye and hair cells in the ear.  She explores the cell biology of photoreceptors with mouse models of Usher Syndrome and a combination of approaches in molecular and cellular biology, biochemistry, electrophysiology, behavior and microscopy.

Portrait Of Vision Scientist: Ann Morris


Ann Morris from the University of Kentucky studies the zebrafish (Danio rerio).  In particular, she studies the ability of zebrafish retinas to regenerate following retinal injury or damage.  Retinal regeneration is an interesting phenomenon that mammalians seem to lack and yet zebrafish manage to do this despite having a retina that in many ways is far more complex than the mammalian retina.

Ann talks about her work in the following video from the University of Kentucky: Continue reading “Portrait Of Vision Scientist: Ann Morris”

Dr. Bäerbel Rohrer In Berlin

Barb Rohrer

My colleague Dr. Wolfgang Baehr at the University of Utah sends this image of friend of Webvision, Dr. Bäerbel Rohrer from Medical University, South Carolina taken last week when they ran into each other in Berlin, Germany.

Its always fun to run into friends and colleagues in different parts of the world.  We will look forward to visiting with them both at ARVO 2014, down in Orlando, Florida in the next few weeks.

Portrait Of Vision Scientist: Stuart Mangel, Ph.D.


This image of Stuart Mangel was made in Berlin, Germany at the 2012 ISER meeting.  Stuart is Professor in the Department of Neuroscience at Ohio State University.  Stuart came out of John Dowling’s lab at Harvard and has contributed mightily to our understanding of synaptic plasticity, circadian rhythms and retinal circuitry/information processing in the retina.

Its amazing how few people in the CNS community make the link between brain and retina, but Stuart has been one of the strongest proponents of understanding CNS in the context of retinal study.  This is important not just from the perspective of the CNS, but also so that we have a fundamental understanding of how the retina works in health and disease.  Finally, Stuart’s lab is one of those few labs that also understands the importance behind an understanding of retinal circuitry, but also how that circuitry results in information processing.  His work in how directional selectivity functions will be critical in elucidating how neural systems handle data streams encoded through the visual system.

Portrait Of Vision Scientist: Michael Redmond, Ph.D.

We have a category here on Webvision for historical images of scientists called Who’s That? designed to show portraits of vision scientists in historical context.  Where they came from, etc…  After discussing some, we thought it would be nice to have some more contemporary imagery as well.  Of course if Webvision sticks around for years to come, then the contemporary portraits will tend to conflate with the historical portraits some, but the distinction is worth mentioning from a provenance perspective.  And while there is a reasonable expectation of that happening given the Webvision is now over 17 years old and going strong, we’ll deal with that issue when the time comes…

By the way, submission of images of vision scientists are welcome for both categories, Who’s That? and Portraits of Scientists from Webvisions readership.  We’d love to see what you send in.

So, onto the first contemporary portrait:  This shot of Michael Redmond was made in Berlin, Germany at the 2012 ISER meeting.  Michael is the chief of the Laboratory of Retinal Cell and Molecular Biology at the National Eye Institute.  His research has historically focused on RPE65, a protein involved in the retinal cycle of Vitamin A.  Michael’s lab works with normal retina  as well as retinal degenerative diseases in an effort to understand how RPE65 works in mouse models of RPE65 defects.  The really interesting aspect of his work with RPE65 has not been the knockout mouse models, but the efforts to modify RPE65 and investigate its role in the visual process with all of the attendant insights into disease that those efforts bring.

Who’s That? Wolfgang Baehr

This photograph of a young scientist in training is the second in the Who’s That? category here on Webvision.  The inaugural post in this category explains the idea behind these posts, but this post shows us, as you’ve deduced from the post title, a young Wolfgang Baehr seen in the Institute for Physical Chemistry at the University of Heidelberg in 1963.  Incidentally, one of Wolfgang’s sons is studying at Heidelberg University and looks shockingly like him in this photo.

Wolfgang was born in Mannheim, Germany and studied organic chemistry while at the University of Heidelberg before moving on to graduate school and then where we find him today in vision science.

Who’s That? Ning Tian

This is the first photograph in a new category, “Who’s That?”, a evolving compendium of found imagery from years back of vision scientists.  The idea is that on occasion, one runs across imagery of vision scientists from other times and it makes for a compelling look back at history.  At the 2007 ARVO, Don Fox helped set up a presentation on the early years of ARVO where he showed some images of John Dowling, George Wald, Brian Boycott and more while Bob BarlowJohn Dowling and Harris Ripps spoke for almost two hours about the early history of ARVO and neuroscience research at the Marine Biology Lab at Woods Hole.
