My name is Sebastian Liem. I'm a PhD student at the GRAPPA Institute, University of Amsterdam. I'm working on Beyond the Standard Model phenomenology, and trying to figure out what dark matter is. Currently I'm looking into effective field theory models.

Easiest way to reach me is via e-mail.

Texts

Constraining Supersymmetry using Simplified Models is the title of my Master's thesis. I investigated how to reinterpret experimental constraints on simplified models as constraints on supersymmetric models such as the cMSSM and the pMSSM. I also developed SASS, a software framework to automate this process.

Faster Dark Matter Calculations Using the GPU is the title of my Bachelor's thesis. I investigated the value of, and the effort required, porting DarkSUSY to the GPU platform CUDA. For a test program I achieved a ~47-fold speedup.

Code

I'm very fond of programming but can rarely find the time to involve myself in larger projects. Some of the small stuff I written are ackord, code for a chording keyboard, and slit, a simple literate programming tool.

Observation from walking

Freshly fallen snow and fifteen second countdown make for very quick hide-n-seek rounds. Oh well, at least the kids had fun.
