About Me

My professional interests are centered around theoretical and applied vision research. I am interested in developing math models of the visual system which explain how our eyesight is affected by ocular, neurological, and external environmental factors. The restoration and enhancement of visual function is central to my passion for vision science.

Background (University of Minnesota)

Primary Academic Work and Research

I received a Ph.D. and a B.A. in Psychology from the University of Minnesota, where I performed research under several NIH grants. Most notably, I codeveloped three reading acuity charts (MNREAD-Portuguese, Spanish, and Hindi) which are used for vision research and in clinical (i.e., optometric and vision rehabilitation) settings.

My dissertation work modeled visual impairment and physical environments, in order to understand and enhance visual accessibility for visually-impaired pedestrians. I focused on bridging the gap between illuminated physical environments and rendered virtual environments. In addition to comparing real and simulated environments, I proposed, developed, and tested a computational model of visual impairment. Using the methods described in my dissertation, researchers can reliably test the visibility of environmental spaces with models of visual impairment on a desktop computer environment.

Additional Research Contributions

I have a wide range of computer, electronic, and mechanical engineering skills that have greatly enhanced my abilities and contributions as a vision scientist.

I have accumulated numerous technical skills, including: perceptual psychophysics, Bayesian modeling, signal detection theory, high dynamic range imaging, 3D environmental modeling, physically-based rendering, optical system modeling, digital filter design and implementation, data acquisition, and a wide variety of statistical inference and modeling techniques. I am an expert in Matlab scientific computing, image processing, and statistical and mathematical modeling.

In addition to primary research during my studentship at the University of Minnesota, I was an Instructional Technology Fellow for two years in the College of Liberal Arts, where I taught Matlab to psychology undergraduate and graduate students. I was also a Section Leader and Instructor for two undergraduate courses in the Department of Psychology. Finally, I spent over ten years developing electronic, microcontroller, mechanical, and optical apparatuses for investigators at the University of Minnesota, including two years as the Mechanical and Electronics Shop Manager for the Department of Psychology.

Current Interests (The Ohio State University)

I am a Post Doctoral Researcher at The Ohio State University in the Department of Psychology—continuing my dissertation work in modeling and rendering 3D objects for theoretical vision research.

I am interested in computational models of the visual system and how they can improve clinical vision research. I am currently considering applying for a NIH Post Doctoral Training Grant that would focus on extending mathematical modeling of OCT scan technology as a clinical diagnostic and research tool.
