Recent Publications

Projects

Project’s we’re currently focusing on: Molecular Dynamics, Differentiable simulators, ML Compositionality and Generative Modelling. For prospective students, look at these in particular.

Simulating a Virtual Cell

Simulating a virtual cell using ML-derived coarse-grained potentials

ML Compositionality

ML Compositionality refers to the idea of building a large ML model from modular and reusable building blocks, just like LEGO.

Image Reconstruction

Using ML and compressed sensing techniques to improve the quality, speed and cost of medical scans.

Generative Modelling

Develop models for generation, reconstruction and manipulation of images, text or other high-dimensional data.

ML Benchmarks

We build benchmarks and organize community challenges on key medical prediction problems.

Disease progression modelling

Modelling the progression of Alzheimer’s disease and related neurodegenerative diseases

Differentiable Simulators

Building MRI/PET/Diffusion/MD simulators in PyTorch that can enable us to perform backpropagation through the entire simulator

ML for Molecular Dynamics

Using AI/ML for scaling Molecular Dynamics simulations of proteins.

Medical Visualisation

Building software and ML models for the visualisation of medical images. An example project is BrainPainter.

Join My Lab

  • Postdocs: Email me directly. I hire all year round.
  • PhD students: Submit a PhD application through UCSC grad amissions. The application deadline is in early January of every year. You are welcome to email me earlier to enquire about our lab or to visit us.
  • UCSC undergraduates/Masters students: I can supervise you on a thesis project if we come up with a very interesting idea, or if you propose your own project. You’re welcome to email me or my PhD students and ask them to suggest a project, or to brainstorm ideas. Another option is to start by helping one of my exiting PhD students on their project. Also see the projects and their associated readings.
  • Visiting students: If you’re a PhD student or postdoc from another research lab and want to visit us for 6-months or 1-year to gain more skills or collaborate, send me an email.
