Abraham Joseph

PhD Candidate in Computer Science · Singapore Management University

I build real-time sensing systems that measure how people move, train, and recover — shaped by years of coaching elite athletes and competing on the mats myself.

01 — Research

Deploying Practical Systems

Coaches and clinicians make fast decisions with imperfect data. I study how they actually use sports-science technology, and build camera- and drone-based systems that track movement in real time, with the long-term goal of helping older adults stay active and independent.

PhD thesis · in progress

Towards Practical Real-time Sensing Systems for Fine-Grained Exercise Analysis

Brings together sports-HCI studies of how coaches use sports-science tools and real-time camera-based systems for fine-grained exercise tracking.

02 — Coaching

I come from the gym floor

At Florida I coached Division I football players and worked as a sports scientist, and I still coach today. That's where my research focus comes from. I am building low-cost systems that can actually be deployed, and that tell people something useful about how they move.

03 — On the mats

Still an athlete.

I train and compete in Brazilian Jiu-Jitsu, and I recently got my purple belt. The mats keep me close to discipline, repetition, and performance under pressure. Those are the things my research tries to measure.
