Research Interests

Our lab conducts research at the intersection of clinical neuropsychology and cognitive neuroscience, and focuses heavily on EEG methods. Studies typically address one of two related lines of research:

1. The first line of studies examine how correlations between brain activity and cognitive ability vary as a function of different task characteristics. We hope that by studying the relations between brain activity and cognitive functioning in general, we can identify principles that will inform eventual EEG applications in assessment and treatment of cognitive disorders. Another long-term goal of this work is to help refine conceptions of cognitive ability itself and its relation to everyday task performance:
   • ERP correlates of the decision time-IQ relationship
   • Relation of neural anticipatory mechanisms to fluid intelligence,
   • Intelligence and Visual Mismatch Negativity,
   • Electrophysiological approaches to studying intelligence
   • Intelligence and uncertainty
2. The second line of research is focused on testing specific EEG markers for potential medium and long-term applications in neuropsychological assessment. Published examples include studies examining EEG correlates of executive functioning, and broader neuropsychological performance. Ongoing studies and several under review are looking at various EEG markers, including the EEG aperiodic slope, mid-frontal theta power, and the N400 event-related potential, as well behavioral measures obtained via smart-phone based ecological momentary assessment. We also recently concluded a grant from the National Institute on Aging, aiming to identify EEG markers that may differentiate healthy older adults from those with Mild Cognitive Impairment or early Alzheimer’s disease.

• • Neurocognitive and neurophysiological correlates of motor planning
  • Reliability and sensitivity of the EEG power spectrum as a biomarker
  • Resting EEG spectral slopes relate to age differences in information processing speed
  • EMA and temporal variability in assessing executive functioning

Most studies in the lab combine standardized cognitive assessments (as typically applied in neuropsychological assessment) with experimental tasks and ERP or time-frequency analysis of task-related and spontaneous EEG data.

Current populations of interest include community-dwelling older and younger adults, and individuals who have been diagnosed with Mild Cognitive Impairment or early Alzheimer’s disease. Over time we hope to expand our research to include additional neuropsychiatric groups.

Opportunities for Students

Dr. Euler will not be reviewing applications for the current application cycle (entering class of Fall 2025). Please do not apply. We anticipate one opening for a graduate student in Fall 2026.
