I develop multimodal imaging biomarkers to stratify patients with Parkinson's disease (PD), dementia with Lewy bodies (DLB), and Alzheimer's disease (AD) for therapeutic trials and to monitor disease progression. My program centers on <strong>cholinergic vulnerability</strong>: I built a multimodal MRI signature of nucleus basalis of Meynert (Ch4) degeneration, complemented MRI with resting-state EEG markers of cognitive fluctuations, and modeled PD progression to identify rapid progressors for trial enrichment.

<p>Cholinergic vulnerability and cognition in Parkinson's disease and Alzheimer's disease and related dementias</p>
</div>
<p class="research-vision-text">
PD, DLB, and AD are heterogeneous in their clinical features, pathology, and progression, and enrolling biologically diverse patients into trials of target-specific therapies can dilute treatment effects. Degeneration of the <strong>nucleus basalis of Meynert (Ch4)</strong>, which supplies most cholinergic input to the cortex, is shared by all three diseases and is the rationale for cholinesterase inhibitors, yet response to these drugs varies widely, and newer cholinergic therapies are still tested without target enrichment. I have developed a <strong>multimodal imaging signature of Ch4 degeneration</strong> and am extending it across PD, DLB, and AD to test whether it improves patient selection. Even if treatment selection proves challenging, a validated staging marker could inform prognosis, interpretation of treatment response, and assessment of remaining target tissue before Ch4 deep brain stimulation or gene therapy.

<h4>Identifying Ch4 degeneration in vivo</h4>
<p class="pillar-text">Ch4 is small and difficult to delineate with conventional MRI volumetry. Using probabilistic cytoarchitectonic maps, I quantified Ch4 integrity from standard MRI and identified a subtype of PD mild cognitive impairment (PD-MCI) defined by MRI evidence of Ch4 degeneration. In resting-state fMRI, Ch4 connectivity with the attention-related cingulo-opercular network mediated the relationship between Ch4 degeneration and cognition, a candidate circuit link to cognitive impairment.</p>

<h4>EEG Signature of Lewy Body Dementia</h4>
<p class="pillar-text">EEG is inexpensive, repeatable, and widely available, and cognitive fluctuations in Lewy body dementia are commonly attributed to cholinergic degeneration. In the NIH R21 AG077469 study, I analyzed resting-state EEG in patients with Lewy body disease and built a machine-learning model that detects cognitive fluctuations. Building on this work, I contributed pilot data and the multimodal Ch4 MRI pipeline to a funded mechanistic R01 on cholinergic degeneration and cognitive fluctuations, which currently supports my position.</p>

<h4>Modeling Disease Progression</h4>
<p class="pillar-text">Heterogeneity in progression also complicates disease-modifying trials. Using PPMI, I modeled ten-year progression milestones across clinical, pathological, and data-driven PD subtypes; diffuse-malignant PD progressed fastest. To identify these patients prospectively, I developed disease-duration–specific percentiles for the first five years after diagnosis, released an open-source subtype calculator, and characterized the genetic associations of these subtypes. This work converges with my imaging research: patients with PD-MCI and MRI evidence of Ch4 degeneration overlap with those classified as diffuse-malignant PD.</p>
