Khulan Batsuuri has graduated and received her MD from the School of Medicine, Mongolian National University of Health Sciences and continued her study in MS in Neuroscience program in the University of Hartford. Before enrolling in PhD in Vision Science program at the SUNY College of Optometry, she has worked on an epigenetic project to study the effects of transcription factors, Ezh2 and G9a, on retinal ganglion cells at Schepen`s Eye Research Institute, Boston. Her research interest is retinal neurodegeneration, including Glaucoma and optic nerve regeneration. She is looking forward to working with Dr.Bloomfield and Dr.Viswanathan to study the possibility of early detection and potential treatment of the Glaucoma.
Zhehao Huang received his Bachelor of Science from the School of Psychological and Cognitive Science, Peking University. He entered the PhD program in 2015, and now is a fourth-year student in Dr. Qasim Zaidi’s lab. During the first year, he focused on a sequential attraction in human color perception, and has presented in VSS 2016. He is currently working on a behavior and neural model of illuminant and color estimation in complex color scenes.
Sohrab received his MSc in biomedical engineering from Iran University of Science and Technology. He is second year PhD student working under supervision of Dr. Jose-Manuel Alonso. He is currently working on a model to explain how afferents coming from both eyes are arranged in primary visual cortex (V1) precisely within small portion of our brain. The visual information coming from our both eyes are segregated based on specific features like orientation, or retinal position (retinotopy). This segregation results in several overlaid visual maps. The focus of his research is to study these maps more accurately than the past through developing some image processing techniques. The final goal of this project is to reach the knowledge required to design a chip that could be replaced with this part of visual system to help those who are suffering from related diseases.
Rakesh Nanjappa graduated in 2014 from University of Hyderabad (India) with Integrated Masters in Optometry and Vision Science, after which he did one year of course work in M.Phil Cognitive Science from the same university. His broad research interest is to investigate the relationship between eye movements and attention. His masters thesis explored the effect of low-level image features on fixational eye movements. His first project in the PhD program was to explore the role of microsaccades in high acuity visuomotor tasks. He is currently studying the neural correlates of ‘inhibition of return’ by recording from superior colliculus in NHP during free visual search. His research advisor is Dr. Robert McPeek.

Carmen Pons completed her degree at the Medical School of the University Miguel Hernández (Alicante, Spain). Her ultimate goal is to complete my Doctorate in Vision Science at SUNY Optometry with her advisor, Dr. Jose Manuel Alonso in order to improve her own competence in such an interesting field. She would like to focus her research career towards achieving two objectives. Firstly, opening new horizons and helping to increment our knowledge in this field and secondly, pioneer new ways that will contribute to the development of medical curative processes. She proposes to meet these two goals by developing a working model where laboratory research is closely related to clinical work. Her aim is to bridge the gap between basic research and clinical practice. For example, use the experience acquired in clinical work to improve experimental design in basic research.

Rita Nieu attended the University of California, Davis and received a Bachelors of Science in Genetics with minors in Psychology and Communications. She worked as a research technician in the lab of John Vogel at the USDA before enrolling in the OD/MS program at SUNY College of Optometry. In collaboration with her mentor, Dr Benavente-Perez, her research is focused on detecting changes in retinal function during myopia progression in a primate model through the use of ERG and VEP.
Tatsiana Palavets received her B.A. in Biological Sciences from Hunter College, CUNY. She is currently in OD/MS in program at SUNY College of Optometry. Her Masters Thesis Advisor is Dr. Mark Rosenfield, MC OPTOM, PHD. Her Research project focuses on the “Use of Blue-Blocking Filters to Reduce Digital Eye Strain.” Digital Eye Strain (DES) refers to the visual and ocular symptoms commonly experienced when viewing digital screens. The study examined the effect of a blue-blocking filter on these symptoms while reading continuously from a tablet computer for 30 minutes. In addition, ocular accommodation, pupil size, and the size of the vertical palpebral aperture were also monitored during the task. Preliminary results suggest that the blue-blocking filters do not reduce symptoms of DES.
Brenda Tan graduated with a B.S. in Biology from Brown University. Her M.S. Research Advisors are Dr. Stewart Bloomfield and Dr. David Troilo. Her research project focuses on the “Attenuation of Myopic Progression Seen in a Connexin 36 Knockout Mouse Model of Myopia.” The aim of this project is threefold—first to establish a mouse model of myopia, second to examine the environmental effect of dim lighting on myopic progression and third to understand its genetic component by using a knock out model of Connexin 36. In order to perfect the mouse model and provide insight into the widespread variation in measurements amongst labs, I looked at three methods of refraction—1) on the awake and lightly restrained mouse, 2) on an awake and cyclopleged mouse and 3) on a cyclopleged and anesthetized mouse. Refraction was measured using an infrared power refractor modified by Dr. Frank Schaeffel and axial length measured using an OCT.
