A Longitudinal Study To Identify Early Non-invasive Ocular Markers of Diabetic Complications

This is a human subject study looking at the complications arising in newly diagnosed diabetic patients using non-invasive measures, optical coherence tomography (OCT) and corneal confocal microscope (CCM), indicative of peripheral neuropathy and diabetic retinopathy. Through the use of these devices we would like to determine the onset of corneal nerve fiber alterations and retinal thinning in newly diagnosed diabetics. This information could help investigators find early and reversible biomarkers to target for therapeutic options.

Accessibly of Conversational Agents with Deaf or Blind Users

Using small focus groups, this work aims to understand the experiences, challenges, perceptions, and opportunities for the use of conversational agents (e.g Amazon Alexa and Siri) for users with visual or hearing impairments, with the goal of developing more accessible and inclusive systems.

Investigating Face Processing Behavior and Neural Circuitry

The ability to recognize faces differs across people. We are studying this variability in behavior and in brain responses in young adults (ages 18-25 years) in the Lab of Developmental Neuroscience at Penn State. If eligible, you will do face recognition tasks on the computer and answer survey questions. You may also be asked to participate in another session in which we take pictures of your brain using MRI. Volunteers are paid $10/hr for time in the lab. Interested participants can start the screening processing by clicking on this confidential screening link here: https://pennstate.qualtrics.com/jfe/form/SV_9NPJ20bQAPd0VKZ

Functional magnetic resonance imaging (fMRI) and psychophysical studies of sensory perception and cognition

The purpose of this study is (1) to understand how the brain processes sensory information and (2) how this is affected by factors like blindness or synesthesia. In addition to behavioral testing, the study will use functional magnetic resonance imaging (fMRI) which enables us to take pictures of the brain while you are doing a task, using an instrument called an MRI scanner.
