AI + design
experiences
I love using machine learning, product design, and spatial computing to engineer products at the intersection of environmental and computational intelligence.

machine learning + physics @ nasa
I designed a probabilistic global weather forecasting system by quantifying sensitivity of tropical cyclones, atmospheric rivers, and heat waves to sea surface temperatures, humidity, and wind using HPC clusters.

machine learning + physics @ nasa
I engineered a distributed wildfire early-warning system to produce probabilistic fire spread maps by using Monte Carlo physics simulations to quantify wildfire sensitivity to vegetation, topography, and wind.

electrical + computer engineering @ cornell
I prototyped an autonomous AI robot to diagnose grapevine leafroll diseases and phenotype powdery mildew for 12+ New York vineyards using hyperspectral imaging algorithms and thermal sensors, funded by NASA.

machine learning + spatial computing @ cornell
I designed a neuroadaptive virtual reality interface to study spatial cognition by training convolutional neural networks on EEG signals to analyze perceptual responses to architecture for 3D virtual navigation.

machine learning + robotics @ nasa
I invented an Al outdoor air quality monitoring robot to reduce PM2.5 air pollutants in 4 Dallas schools, publish a Harvard-affiliated research paper, and inform an atmospheric safety bill impacting 2.4K students.

I designed a geospatial AI app to deliver predictive agricultural insights to 50+ vineyards and orchards in 4 countries, helping 4 Napa Valley winegrowers forecast smoke taint during the 2025 California wildfires.

fun stuff
nature photography
every weekend, I run a 5K before sunset. during my lakeside runs through Frisco, I've developed an unexpected habit of taking photos. here are a few!
A vibrant sunset over a lake with pink blossoms in the foreground and houses silhouetted against the golden sky.
cherry blossom
Looking up through a textured tree trunk at a bright, spring green canopy against a blue sky.
canopy
Green leaves and yellow flower clusters on branches photographed from below against a clear bright blue sky.
spring blues
A bare tree silhouetted against a bright blue sky with wispy clouds and golden sunlight streaming through its branches.
winter solstice
Two tiny snowmen sitting on top of a large weathered tree stump in a snowy winter landscape with bare trees in the background.
winter wonderland
A suburban street with brick houses and a bright yellow pickup truck parked in front, featuring a large green tree in the center foreground.
autumn nostalgia
A solitary pink wildflower nestles low in vivid green grass while bare-stemmed wildflowers reach toward a glowing hazy sun, bathing a rolling yellow wildflower meadow in warm golden light.
prairie dusk
A golden sunset casting warm light across an open field with wispy clouds streaking across a blue and yellow gradient sky.
dusk
Wooden dock pilings extend into lake at sunset with golden-orange clouds.
cornerstone
A frost-damaged prickly pear cactus in a gravel bed, silhouetted against a winding blue lake and bright morning sky in a Texas park.

A black metal railing frames a calm spring lake lined with golden reeds and lush green trees under a clear blue Texas sky.
lakeside rail
An owl butterfly with false eyespot markings rests against a mossy wooden post surrounded by layered pink granite rocks, nearly camouflaged in the dim, cave-like corner of a tropical enclosure.

golden channel
A bare, dramatically leaning tree silhouetted against a dual-toned winter sky of blue and gold, overlooking a snow-ringed frozen pond at dusk.
winter dusk
Dark magnolia branch silhouettes arc gracefully across a deep cobalt blue sky, framing a vivid orange and yellow sunset glow bleeding up from the lower left corner with a faint airplane contrail cutting diagonally overhead.
