Hello! I’m Fang Han (pronounced “Fahng,” rhyming with “song”).
I am currently a Research Fellow and Postdoctoral Research Associate in the Department of Radiology at Massachusetts General Hospital (MGH) and Harvard Medical School. I am also enrolled in the CAMPEP-accredited Harvard Medical Physics Certificate Program, working toward professional board certification through the ABR pathway.
Research: From Fundamental Particles to Medical Imaging
Before joining MGH, I earned my PhD in Physics and dedicated 6 years to the Muon g-2 experiment at Fermilab. As a member of the collaboration, I am incredibly honored to be a co-recipient of the 2026 Breakthrough Prize in Fundamental Physics.
My current research focuses on computational medical physics. I specialize in the design optimization, numerical modeling, and system matrix calculation for next-generation SPECT and PET scanners. My work involves self-collimation SPECT, iterative image reconstruction algorithms (such as MLEM and OSEM), and Monte Carlo simulations using GATE and Geant4. I am also actively utilizing ray-tracing methods for large-scale system matrix calculations.
Computing, Code & Customization
I rely heavily on high-performance computing (HPC), GPU-accelerated computing, and AI exploration to drive my research forward. I frequently utilize PyTorch for large-scale parallelization, deep learning model integration, and scientific calculations on Slurm-managed clusters.
On the desktop side, I am a dedicated Linux enthusiast who loves building a highly customized, efficient workflow. My primary development environment runs on Arch Linux with the Hyprland window manager. In the terminal, I use a combination of Ghostty, Zellij, Starship, and Zim.
Beyond the Lab
When I am not writing code or running simulations, I have a wide range of interests:
- Philosophy of Science: I enjoy exploring the history of science, particularly the philosophical shift from classical to quantum mechanics, and the dynamic between reductionism and complex systems.
- Generative AI & Digital Art: I love experimenting with AI-assisted creative workflows, integrating Blender with Stable Diffusion, ComfyUI, and ControlNet. My wife is also an expert in generative digital art, which makes for inspiring discussions at home!
- Sports: I enjoy playing badminton to stay active and unwind.
- Culinary Exploration: I am a passionate food enthusiast. Whether it’s perfecting my red cooked meat recipe at home or hunting down the best authentic Yunnan cuisine and hotpot in the Boston area, I find cooking and exploring food to be incredibly relaxing.
I currently live in Winchester, Massachusetts, with my family. If you share an interest in computational physics, medical imaging, Linux ricing, or know a great local restaurant, I would love to connect!
