Program / Degree Being Pursued: PhD in Vision Science

Supervisor: Dr. Arathy Kartha

Research Interests: Quantifying functional vision and higher-order visual functions in individuals with cerebral visual impairment, visual neuroscience

Favorite Fact About the Eye: Seeing is not just about having healthy eyes; the brain plays a huge role in how we interpret and interact with the visual world. Two people can have the same visual acuity but experience and use vision very differently.

Research Summary: My research focuses on cerebral visual impairment (CVI), a condition in which visual deficits arise from how the brain processes visual information rather than from problems with the eyes themselves. I study how individuals with CVI use vision during everyday tasks like visual search, reading, eye-hand coordination, integration of visual information with other senses, etc. I also study their eye movement behavior, which gives us a lot of information about how the individual is using their vision.

Favorite Thing About SUNY Optometry: I love that SUNY Optometry has people who bring expertise in different areas of vision science research. The opportunity to learn from them and collaborate helps me explore my research from different perspectives.

What I Hope My Research Will Contribute: My research will help us better understand the everyday visual challenges experienced by individuals with CVI and develop assessments that capture how they use vision in real life. Ultimately, I hope this knowledge can guide support and accommodations tailored to each individual’s needs.

Research Inspiration: What drew me to this area was how differently each child with CVI can experience the visual world. My work with children with special needs made me want to understand these individual differences and why a task that is easy for one child can be challenging for another.

Program / Degree Being Pursued: PhD in Vision Science

Supervisor: Dr. Sayan Ghosh

Research Interests: AMD, retinal disease biology, organelle dysfunction, organoids

Favorite Fact About the Eye: The lens is one of the oldest and most protected parts of our body. So old that, if exposed, our own immune system may not recognize it.

Research Summary: Cells contain tiny, specialized compartments called organelles, like lysosomes, mitochondria, and others, that must constantly create, fold, and recycle proteins to keep our body healthy. When these organelles get damaged or stressed with aging or in disease, protein manufacturing, maintenance, and degradation get altered, causing malformed proteins to accumulate uncontrollably like toxic trash. My research tries to understand the underlying signaling pathways linked to this buildup, the inflammation it triggers, and consequent retinal diseases.

What I Hope My Research Will Contribute: Develop therapeutic strategies to nullify altered accumulation of protein and macromolecular debris inside cells, which is key to several neurodegenerative diseases like age-related macular degeneration and Alzheimer’s disease.

Previous Degrees and Institutions: Bachelor of Optometry, Institute of Medicine, Nepal

Program / Degree Being Pursued: PhD in Biological and Vision Science

Supervisor: Jose-Manuel Alonso

Research Interests: Myopia, visual psychophysics, pupil, mechanisms of eye growth regulation and refractive development, emmetropization.

Favorite Fact About the Eye: “The pupil is a window to the brain, small, dynamic, and revealing more about our nervous system than we often realize.”

Research Summary: I study how negative and positive defocus affect visuomotor functions using the Pupil Labs Neon eye tracker and the VEET, aiming to uncover how lens-modulated eye growth is mediated by changes in pupil size and retinal illumination. My results show that negative lenses cause pupil constriction, which could potentially induce human myopia by reducing retinal illumination, a form of visual deprivation akin to an absence of light. These results have the potential to cause a paradigm shift in myopia research and current approaches to myopia control.

Favorite Thing About SUNY Optometry: Coming to SUNY Optometry as an international PhD student, I’ve really valued being part of such a diverse community, the opportunity to grow through teaching as a TA, and, most importantly, having a supportive PI who has encouraged me to explore, learn, and grow as a researcher.

Research Inspiration: My clinical background in optometry sparked my interest in understanding what happens beyond what we can observe in routine eye care. This led me to study the mechanisms underlying visual perception, pupil responses, and ocular growth, with a particular focus on myopia, refractive development, and eye growth. I’m motivated by the opportunity to understand how visual experience shapes the developing eye and contributes to emmetropization.

Program / Degree Being Pursued: PhD

Supervisor: Lisa A. Ostrin

Research Interests: Light and spectral composition, emmetropization, and myopia

Favorite Fact About the Eye: The individualization, overlap, and integration of specific visual pathways from the eye to the brain.

Research Summary: My research investigates whether specific wavelengths of light can promote normal emmetropization of the eye. I am particularly interested in understanding how spectral composition influences ocular growth and refractive development. Additionally, I explore whether exposure to specific wavelengths of light can mitigate the effects of near work on myopia progression.

What I Hope My Research Will Contribute: To identify visual cues that delay or prevent the onset of myopia and discover new treatment modalities to control myopia progression, with the aim of reducing the burden of myopia on society.

Research Inspiration: I am fascinated by the role of light in visual development and its potential to influence eye growth and refractive outcomes.

Favorite Thing About SUNY Optometry: There’s always a fascinating research talk to attend, engaging discussions with colleagues, a game of ping-pong to play, and a view of the Empire State Building just outside the window.

Previous Degrees and Institutions: Doctor of Optometry, University of Benin, Nigeria

Program / Degree Being Pursued: PhD in Vision Science

Supervisor: Dr. Nicole M. Putnam

Research Interests: Vascular biomarkers of neurodegeneration, high-resolution adaptive optics in vivo retinal imaging, myopia and susceptibility to glaucomatous degeneration, emmetropization and retinal stretch in myopia.

Favorite Fact About the Eye: Optically speaking, the eye is a mess of aberrations, but our neural processing gives us stunning spatial resolution despite it.

Research Summary: I am using adaptive optics, a technology that corrects the eye’s optical imperfections to image cells down to 0.7 microns to investigate retinal stretching in young adults with myopia. By mapping the photoreceptor mosaic and microvascular template, I can precisely quantify how structural elongation alters these microscopic networks. Ultimately, this work aims to uncover how these myopic cellular and microvascular changes increase a patient’s susceptibility to glaucoma.

Favorite Thing About SUNY Optometry: Fellow graduate students

What I Hope My Research Will Contribute: Early detection of retinal neurodegeneration and, as an extension, systemic neuronal disorders.

Research Inspiration: The unwavering challenge of managing neuroretinal disorders when larger, clinically detectable structural defects and visual function loss precede clinical presentation. Simply put: Current clinical signs of retinal disorders appear after cellular and functional vision loss has already occurred, deterring the effectiveness of clinical therapeutics.

Program / Degree Being Pursued: PhD in Vision Science

Supervisor: Dr. Alexandra Benavente-Perez

Research Interests: Myopia, emmetropization, optics, and retinal physiology

Favorite Fact About the Eye: The image projected onto our retina is upside down, yet we perceive the world upright.

Research Summary: My research focuses on understanding the mechanisms underlying myopia and visually guided eye growth. I investigate how retinal function and optical properties change during development and in response to altered visual experience.

Research Inspiration: My interest in myopia research grew from my clinical background in optometry, where I saw firsthand how common and increasingly important myopia is as a global public health challenge. This inspired me to look beyond correcting myopia to understanding why the eye becomes myopic in the first place. I became particularly fascinated by emmetropization, how visual signals guide the developing eye toward appropriate growth, and how disruption of this process can lead to refractive error. My research now focuses on understanding these retinal and optical mechanisms, with the long-term goal of contributing to better strategies for preventing and controlling myopia.

Favorite Thing About SUNY Optometry: The collaborative environment and opportunity to connect basic vision research with clinically relevant questions.
