Making visual
intelligence useful.
I am a PhD candidate and AI researcher working where medical imaging, computer vision, and real-world decision making meet.
02 / TWO TRACKS
Clinical research in aortic surgery and computer-vision product development.
VENTURE
At Exersight, I build computer-vision systems for better strength training.
03 / SELECTED WORK
Three projects across clinical research, strength training, and machine learning.
AI for aortic surgery.
I work on acute type A aortic dissection—a life-threatening tear in the section of the body’s main artery closest to the heart—and investigate how medical imaging and AI can support surgery.
View project
Exersight.
We are building a camera-based system that recognizes exercises, counts repetitions, and provides real-time feedback in the free-weight area.
View project
Assessing aggressive driving behaviour.
This research compares attention-based models for detecting aggressive actions in driving video and explores spatial-temporal cues for interpreting their predictions.
