Dr. John Gonzeles

John Gonzales, M.D.

Dr. Gonzales is an Assistant Professor of Ophthalmology at the University of California at San Francisco. His interest involves the diagnosis and management of infectious and non-infectious inflammatory conditions of the eye (uveitis). Dr. Gonzales is currently the Principal Investigator for the research study Non- Sjögren's Syndrome- and Sjögren's Syndrome-related Keratoconjunctivitis SICCA: A Spectrum of Inflammatory Dry Eye (NIH/NEI K23EY026998).

  • Non-Sjögren’s syndrome- and Sjögren’s syndrome-related keratoconjunctivitis

What inspired you to study the eye?

There was something about the eye that drew me to appreciate it. I still derive a great sense of adventure every time I look into someone's eye to examine their retina. To me it's like diving underwater and exploring a whole new world.

Dr. Luis Martinez-Velazquez

Luis Martinez-Velazquez, Ph.D.

Dr. Martinez-Velazquez is currently completing his medical school training as part of the combined M.D./Ph.D. program in the Department of Neuroscience and Physiology at New York University School of Medicine. He completed his Ph.D. training in 2017, and he hopes to pursue a residency in ophthalmology after receiving his M.D. early next year. His research interests involve the cellular neuroscience of genetic conditions that cause loss of vision, particularly retinal degeneration. His goal is to contribute to the understanding of the normal function of genes associated with retinal dystrophies, with the hope that placing these genes into molecular pathways can help generate appropriate therapies to treat vision loss. Dr. Martinez-Velazquez was the Principal Investigator for a Predoctoral Fellowship titled Determining the Function of Retinal Degeneration 3 in Ciliated Sensory Neurons (NIH/NEI EY024836).

Why did you decide to become a scientist?

Soon after graduating as an engineer, I had an opportunity to come to the United States and work in a neuroscience laboratory. I did not know much about neuroscience at the time, but I soon became fascinated by it. Although we know a lot about how our brains work, there’s still so much to discover.

Dr. Dolly Ann Padovani-Claudio

Dolly Ann Padovani-Claudio, M.D., Ph.D.

Dr. Padovani-Claudio is an Assistant Professor of Pediatric Ophthalmology and Strabismus in the Department of Ophthalmology and Visual Sciences at Vanderbilt University Medical Center.

Areas of expertise:

  • Retinopathy of prematurity
  • Diabetic retinopathy
  • Pediatric ophthalmology
  • Pediatric and adult strabismus
  • Vascular diseases of the retina

Why did you decide to become a scientist?

During my first summer research experience, I learned that there is no such thing as incorrect results from a well-designed and executed experiment — it will always provide knowledge, regardless if the results fit one’s hypothesis. I was fascinated by this concept.

Dr. Alexandro Ramirez

Alexandro Ramirez, Ph.D.

Dr. Ramirez is a Postdoctoral Researcher at Weill Cornell Medical College where he focuses on systems neuroscience.

Why did you decide to become a scientist?

At first, I did not know I wanted to pursue a career in science. However, I became interested in science when my brother David was born with Down syndrome. I wondered how the brain develops — and why some children, like my brother, were born with severe learning disabilities.
