Research Experience

August 2021 — Present

I collaborate with TBIMS researchers to investigate how the social drivers of health and psychosocial factors influence health outcomes after moderate-to-severe TBI.

August 2017 — December 2021

Graduate Research Assistant | UT Clinical Neuroscience Lab

August 2017 — December 2021

I collected and analyzed neuropsychological and neuroimaging data to study the effects of transcranial laser therapy on cognitive performance in adults with and without mild cognitive impairment, involving 10 visits with laser therapy, cognitive tests, and physical health measures.

May 2015 — May 2017

Undergraduate Research Assistant | CI Therapy Research Group

May 2015 — May 2017

I administered constraint-induced biofeedback therapy to an individual with motor complete tetraplegia, analyzing training data to assess recovery; I validated a neuroimaging pipeline by comparing longitudinal MRI results to simulated post-treatment changes; and I analyzed MRI data for a study on improving hand function in individuals with multiple sclerosis.

Core Values

Structural Drivers of Health Inequity

Brain injury does not occur in a vacuum, and neither does recovery. A person's health trajectory is shaped long before and long after any single injury by the individual's place of residence, the resources they can leverage, and the systems they must navigate. I study health as a function of structural conditions rather than individual circumstances. Using social drivers of health, administrative data, and geospatial methodologies, my work identifies where health disparities originate and how systems can be redesigned to distribute health more equitably.

Brain Injury at the Intersection of Health and Justice

Traumatic brain injury (TBI) is dramatically overrepresented among justice-involved individuals, with meta-analytic estimates placing lifetime prevalence around 50-60% among incarcerated adults—far exceeding general population rates. Yet this population is routinely excluded from rehabilitation research, systematically unaddressed by clinical screening, and left without specialized care, even as untreated TBI correlates with increased disciplinary infractions and higher recidivism. My research centers on the intersection of health and justice systems—examining how unaddressed neurotrauma, criminalization, and structural neglect compound one another, and designing population-level interventions to interrupt these cycles rather than reinforce them.

Integrity and Transparency

I believe that scientific progress is built on trust, reproducibility, and open collaboration. To uphold these values, I provide written tutorials on my blog detailing the methodologies and R code I've used to analyze data in my past research, ensuring that others can replicate, critique, and build upon my work. My goal is to foster accountability and contribute to a culture of openness that accelerates meaningful advancements in the field through the prioritization of clear reporting and accessible research practices.

Knowledge Translation and Policy Impact

Epidemiological data is only as powerful as its reach. I write to translate complex quantitative findings into tools for real-world change—reshaping healthcare in re-entry and equipping advocates to push for reform. Ultimately, my aim is for research to extend far past publication: influencing surveillance systems, shaping legislation, and transforming the everyday decisions that determine whether members of underserved populations—including those living with brain injuries—are seen or forgotten.
