What I’ve built

Research only matters when it reaches the people it was meant to help. These are the tools and movements that carry the work to families.

  • CareMobi™

  • The Enlightened Caregiver

  • Tailored Nutrition

Age-tech

CareMobi™

An award-winning mobile app, built in my NYU lab, that helps everyone caring for a person with dementia stay on the same page — family, adult day centers, and primary care.

The CareMobi™ identity, animated. No sound.

Caregiving falls apart in the gaps between people.

The movement

The Enlightened Caregiver

A movement that empowers families with practical, plain-language guidance on how to get optimal — not usual — care for the people they love. It’s where the research leaves the journal and meets the family at 2 a.m.

Innovation

Tailored Nutrition

Tailored Nutrition

In an era of precision health, serving every older adult the same meal regardless of their medical conditions, preferences, or nutritional needs is no longer enough.

We leverage AI to track not just what a person was served but what they actually consumed in busy settings where nutrition is fundamental but often overlooked.

Tailored Nutrition reimagines how we support nutrition in older adults by shifting the focus from what is served to what is actually consumed. Too often, nutrition programs measure the meals placed in front of someone rather than what they eat—missing the earliest signs of declining health. Imagine an older father who begins leaving more and more food on his plate. Over several weeks he loses weight, becomes weaker, and is hospitalized, while his family and clinicians struggle to understand what changed. The warning signs were there all along, but no one was measuring what mattered.

Served, then eaten

One meal, photographed twice. The control below is the app’s own.

The meal log’s Before tab: the plate as it was served, a meal overview dial reading 875 calories, and every item listed with its own macros.

875calories

What was served.

Full portions, listed item by item.

The meal log’s After tab: the same plate partly eaten, an overview dial reading 514 calories, and an “amount eaten” slider on each item.

514calories

What was actually eaten.

Estimated from a second photograph, item by item.

The screens in full

One screen at a time. It scrolls itself — touch it to take over.

The nutrition screen with nothing logged: a daily progress dial reading 0 of 2,100 calories consumed, and a button to log the first meal.
The same nutrition screen after a day of meals: the dial reads 1,140 of 2,100 calories consumed, and each meal is listed with its carbohydrate, fat and protein totals.
The meal log mid-analysis: a photograph of a plate overlaid with “Analyzing Photo”, the line “Calculating calories…”, and a “Notify me when completed” switch.

    Adult day services

    I have developed a national program of research bringing scientific rigor, quality measures, technology, and data infrastructure to adult day services.
