Projects done during my PhD

My PhD research was done at LIACS, Leiden University as part of an NWO project named Data Assistance for Law Enforcement (DALE).

My thesis, named Metrics and Visualisation for Crime Analysis and Genomics is also available online.

Other projects

With Dr. T. Westen of the NFI we search for SNPs in the human genome for various applications.
