I work at the intersection of AI, scientific computing, and software, turning complex data into reliable models, scalable systems, and practical tools for real-world problems.

Sometimes through code,
Sometimes through a camera,
Sometimes with a pencil.

THINGS I THINK ABOUT

Questions that keep
pulling me in.

Choose a topic to follow the question.

PERCEPTION

How do machines make sense of what they see?

This thread runs through scientific imaging, computer vision, particle characterization, classification, detection, segmentation, and environmental imagery.

A CLOSER LOOK AT WHAT I’VE WORKED ON.

Selected Projects

Projects spanning hydrology, scientific imaging, intelligent sensing, and human-centered AI, each shaped by a different question and the technical work required to answer it.

01

Getting the prediction right was only the first question. Could the system remain trustworthy when deliberately challenged?

First, make the building understand.
Then try to fool it.

My dissertation research progresses from Translution, a hybrid Transformer-CNN architecture that learns local and long-range patterns in multivariate sensor data, to ADS-Guard, a defense framework designed to detect and sanitize adversarial perturbations. Together, the work asks how intelligent sensing can remain accurate and trustworthy when conditions stop being friendly.

What does it take to make national-scale hydrologic data and models actually usable?

Making decades of
water data usable.

My work with CIROH lives between environmental science and software infrastructure, connecting NOAA NextGen/ngen modeling, National Water Model and AORC data, geospatial processing, cloud workflows, containers, configuration generation, testing, and reproducibility into systems researchers can actually run.

Can tiny particles be detected and classified while the water is still moving?

Finding microplastics
in motion.

A computer-vision framework for detecting and classifying microplastics under realistic water-monitoring conditions. The study used 4,260 high-resolution images across seven particle categories and introduced Yolov7CS, an attention-enhanced YOLOv7 model integrating channel and spatial attention through CBAM. The system was evaluated across high-resolution, noise-degraded, and real-world imaging conditions, then validated in a water-circulation monitoring platform.

What if intelligent feedback could respond while you perform?

An AI that doesn't
just listen. It responds.

The AI Voice Coach explores a more human side of intelligent systems: combining voice signals, waveform information, body visualization, and synchronized feedback into an interactive experience for singers. Here, the challenge isn't only understanding a signal. It is deciding how an intelligent system should communicate what it understands back to a person.

AND I LOOK AWAY FROM THE SCREEN.

Her Perspective

Traveling, photography, and sketching give me a different pace for the same habit: pay attention.

SKETCHBOOK

Sometimes I trade
the keyboard for a pencil.

The subject changes, but the instinct is the same: slow down enough to notice what is there.

SAY HELLO

What could we
figure out together?

I’m interested in research and engineering opportunities across machine learning, scientific computing, computer vision, and intelligent systems.
