Biography

Dr. Sun’s research interests grew while he was completing his optometry degree in Melbourne, Australia, so much so, that he moved to Boston and pursued research fulltime.  His work on glaucoma, the optic nerve and astrocyte biology began in 2007 when he joined Richard Maslands lab at Massachusetts General Hospital.  During this time, he characterized with great detail the morphological characteristics of optic nerve astrocytes in both normal and diseased eyes, something that had not been done with much clarity before.  He now studies various signaling pathways that may regulate these astrocytic changes.  The overall goal of his research is to understand the function and mechanisms of astrocyte reactivity within the retina and optic nerve, with the goal of determining whether it is better to enhance or reduce certain aspects of their activity during disease.  He uses various models of experiment glaucoma and traumatic optic nerve injury.  His expertise lies in cell biology, cell imaging, functional assays and animal models.  His has been supported by the Fight for Sight Grants-in-Aid, the Brightfocus Foundation, and the National Institutes of Health R01.
