Research Projects

Perceptual Scaling and Discrimination

Designed and conducted psychophysical experiments using MATLAB PsychToolBox, to study visual discrimination in humans, along multiple directions in color space. Developed mathematical models relating perceptual scales and visual discrimination, near and above thresholds. Developed optimized code to automatically calibrate visual displays (CRTs, LED displays) in terms of brightness, temporal frequency, and color, using multiple devices (oscilloscopes, photometers, and spectroradiometers). Mentored undergraduate students running psychophysical research projects.

Blurry Alphabet Recognition with Deep Learning

Trained deep learning neural networks to simulate the perceptual differences of alphabets under different spatial frequency conditions with PyTorch. Used attention map analysis to investigate how life-long exposure to different degrading levels influences perception

Frequency and Duration Influence Auditory Discrimination

Manipulated auditory signals (Fourier analysis, signal processing) to investigate how signal frequency and duration affect people's auditory discrimination. Carried out statistical analysis with R (hypothesis testing, logistic regression, ANOVA, etc.)
