My work in digital health and entrepreneurship

I have also worked to translate scientific findings into real world impact using digital methods. This work from the bench led to innovative new technologies in outcomes assessments in preclinical models of neurological disease; my work was the primary subject of a report in Nature describing the impact of these tools for preclinical science.

I started my company, (subsidiaries of and, in 2013 while in medical school. provides next generation scientific tools using novel technologies including artificial intelligent mazes, digital health apps, vision tracking, virtual reality, drones, and more. The company has been featured in Nature, Huffington Post, Popular Science, Discover Magazine, NPR, and the tools have been used and cited in manuscripts published in Nature and the Proceedings of the National Academy of Sciences. The company is a supplier at over 500 universities and private pharmaceutical companies worldwide and with international distribution in over 40 countries.

My research in Neurological Disease

My career focus has been the acute management of neurological disease with novel therapies and protocols. I have written extensively of novel agents and their effects as well as effects of interventions on outcomes beyond traditional morbidity and mortality including patient reported outcomes and health related quality of life. A few select publications:

My research in healthcare utilization

In addition to studying the management of acute neurological emergencies for individual patients, I have looked at macro trends in hospitalizations in order to understand both regionalization of care and variances in interventions based on volume of location of the center.

My basic science research

I have done work in preclinical models of neurological disease as well for understanding fundamental mechanisms of the complex interplay between the brain and the immune system. I have worked with murine models of ischemic stroke and shown subtle cognitive change using novel methodologies in behavioral testing, akin to patient reported outcomes in the preclinical stage for improved translational therapies to the bedside.

My work in access and disparities in healthcare

My work has also looked into the access and disparities for patients in obtaining care for acute neurological emergencies across both socioeconomic and racial lines.
