small questions, big answers
experiences
I love using physical machine learning, intelligent robotics, and spatial computing to pursue questions at the intersection of environmental and computational intelligence.
Overlapping photo cards showing a global SAR coherence change detection map with red wildfire damage anomalies over polar and equatorial regions, a photograph of the NASA JPL building exterior with the NASA meatball logo, and a multi-panel cyclone track intensity forecast error graph with atmospheric river integral equations, on a white background with a Caltech logo circle and blue geometric shapes.
machine learning + physics @ nasa
I improved the accuracy of probabilistic global weather forecasts for tropical cyclones, atmospheric rivers, and heat waves in atmospheric physics simulations by training graph neural networks on satellite images.
Overlapping photo cards showing a red PCA biplot of North American fungal isolates clustered by principal components, a photograph of the NASA Ames Research Center water tower, and a wildfire burn confidence probability curve comparing logistic regression and CNN model outputs, with a standard deviation formula on a light gray background with a pink blob shape.
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.

atmospheric robotics @ nasa
I patented an AI outdoor air quality monitoring robot to reduce PM2.5 air pollutants in 4 Dallas schools, publish a Harvard-affiliated paper, and inform an atmospheric safety bill impacting 2.4K+ students.
Overlapping cards showing a forecast lead-time graph with shaded confidence bands, a mathematical formula with a sigma summation, a photo of Yale's Harkness Tower against a clear blue sky, and two stacked error trend charts, accented by a navy four-pointed sparkle and a pale blue blob shape, with a navy circular Yale "Y" logo in the bottom right corner.
electrical + computer engineering @ yale
I engineered an AI robot by researching how piezoelectric transducers convert electric potential energy into 3D kinematic motion guided by state estimators, hierarchical motion planning, and reinforcement learning.
Overlapping photo cards displaying a hand holding a green smartphone with a crop analytics dashboard above a pile of fresh vegetables including tomatoes and mushrooms against a blue sky, a smartphone showing an avocado plant disease detection screen beside a whole avocado on a stone pedestal against a cream background, and a smiling farmer in denim overalls and a bucket hat standing in a green agricultural field, arranged on a light gray background with a dark teal organic blob shape and a mint green star-shaped accent.

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.
jet stream
Purple redbud blossoms clustered on dark branches photographed from below against a cloudy gray sky.
spring ornaments
A blooming Eastern redbud tree frames a brilliant golden sunburst over a rippling lakeside, with vivid pink blossoms filling the foreground against a cloudless blue sky.

literary sleuth
from insights about the socialism that governs fungal roots to the works of legendary myrmecologist E.O. Wilson, I love cozying up with a good book.
