Lanya Cai is graduate student starting the 4th year of her PhD program. She came to the program with an inter-discipline educational background including biomedical engineering, electrical engineering, and psychology. During her PhD training, she studied binocular combination, global motion perception, and amblyopia with Dr. Benjamin Backus. Her current research focuses on (1) to identify the parameter space in which binocular global motion perception is measurable, (2) to develop a new model of binocular global motion process that can quantitatively describe human perceptual behaviors during our experimental measurements. She has presented her work on VSS by a talk in 2013 and two posters in 2014 and 2015.

Erin Koch received her BS and MA in Mathematics from American University. She was an adjunct faculty member for one semester and a term faculty member for a year in American University’s Mathematics and Statistics Department. Erin entered the PhD program at the Graduate Center for Vision Research of State University of New York in the Fall of 2013. She is currently studying how different regions of cortical topography shape response properties via physiology and neural modeling. She is also interested in extracting 3-D shape from motion and texture cues. She has presented at both VSS 2015 and SFN 2015.

Cristina Llerena Law
Cristi Llerena Law, a fourth year Ph.D. candidate, is a Doctor of Optometry and a member of the optometry faculty at Nova Southeastern University. Prior to relocating to south Florida in the summer of 2015, she was clinical faculty at SUNY Optometry for nine years. With the help of a National Institutes of Health (NIH) Clinical Research Development Award (K-grant), Dr. Law has been working on transitioning into a career in translational research. Her area of interest is visual neuroplasticity in adult amblyopia and she is currently working with her advisor, Dr. Benjamin Backus to assess and develop binocular treatment modalities for this population. Her work with Dr. Backus in this area has led to several abstracts and publications. In addition, she will continue to work on other projects which have now gained federal funding through her collaboration with Dr. Backus and other colleagues within and outside of SUNY. Her most recent publication, “Stimulus Characteristics Affect Assessment of Pupil Defects in Amblyopia” was published in Optometry and Vision Science in May, 2015.”

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 image features on fixational eye movements. Now he is studying patterns of eye movements made by human participants while they aim and shoot in a computer simulated shooting task. This will reflect the role of eye movements and attention in a high acuity visuomotor task. He has recently presented a poster titled ‘Contextual Saccadic Adaptation as a tool to investigate sequential saccades’ in VSS 2016, St.Pete’s Beach, Florida.

Maria Pons-Torres 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.
Advisor: Dr. Jose-Manuel Alonso
Kaushambi Roy is a third year graduate student in Dr. Stewart Bloomfield’s lab. She completed her BS and MS in University of Calcutta, India. She uses techniques like electrophysiology, pharmacology, confocal imaging and immunohistochemistry to study the role of gap junctions in the retina. Her work particularly involves understanding the role of gap junction in correlated firing between remotely located retinal ganglion cells. Kaushambi was always interested in neuroscience and retina was a model system she wanted to work on. She finds the ongoing research in Dr. Bloomfield’s lab fascinating.

Nefeli Slavi studied Biology in the National and Kapodistrian University of Athens, Greece and completed her Master’s in Medical Neuroscience in Charité, Germany. She came to the U.S. in 2012 to work as a research technician in the lab of Dr. Srinivas at SUNY College of Optometry, where she now conducts her Ph.D. thesis. Nefeli’s research as a graduate student focuses on the role of gap junction channels in the development of age-related nuclear cataracts (PMID:25294879), and in ischemic retinopathies using genetics, molecular and cell biology techniques and electrophysiology.

He completed a Masters in Business Administration from the Northeastern State University of Oklahoma and a Doctor of Optometry from the Southern California College of Optometry. He also completed an Optometric Residency from the Northeastern State University of Oklahoma, College of Optometry. James is currently enrolled in the Ph.D. in Vision Science Program at the SUNY College of Optometry. His current research interest is the field of mild traumatic injury and the phenomenon of photosensitivity. His goal is to find objective biomarkers for these two conditions through dynamic pupillometry.

Next, he earned a Doctorate in Optometry and a Masters in Vision Science at the SUNY State College of Optometry in New York City. He chose to continue his studies through enrollment in the Ph.D. program. His research interests involve exploration of visual processes and psychological states with electrophysiological methods. Kevin is currently working with Dr. McPeek, and aims to elicit the role(s) of the superior colliculus and frontal eye fields in programming of attentional processes and saccadic eye movements.

Lauren E. Wool
Lauren obtained her bachelor’s degree in neuroscience from Dartmouth College, having worked in the lab of Yale Cohen on stimulus categorization in primate auditory cortex. As a member of Qasim Zaidi’s lab at SUNY Optometry, her research interests are color-vision psychophysics, attentional salience, the chromatic circuitry of primate retina, and putative nonlinearities of the short-wavelength (S) color pathway. Through a collaboration with Dennis Dacey at the University of Washington, her current research project is examining color opponency in retinal ganglion cells—in particular, how S cones may contribute to the canonical color tuning of midget ganglion cells.
