A (2 + ε)Factor Approximation Algorithm for Split Vertex Deletion
(Journal article; Peer reviewed, 2020)In the Split Vertex Deletion (SVD) problem, the input is an nvertex undirected graph G and a weight function w: V(G) → ℕ, and the objective is to find a minimum weight subset S of vertices such that GS is a split graph ... 
A 43k Kernel for Planar Dominating Set using ComputerAided Reduction Rule Discovery
(Master thesis, 20160215)In this thesis we explore the technique of Region Decomposition for finding kernels for Planar Dominating Set. We redefine some concepts used in earlier work, fixing some ambiguities on the way. From those concepts we end ... 
A DomainSpecific Language for the Development of Heterogeneous MultiRobot Systems
(Master thesis, 20190628)Robots are becoming more advanced each year and will increasingly become a bigger part of our lives. This thesis explores how modeldriven software engineering can be used in the development of heterogeneous multirobot ... 
A Modular Approach for Creating Web Applications with 3D Geology Using React and X3DOM
(Master thesis, 20190629)The thesis details the work for creating a web application that allows a user to see a visualization for geological data like topography, seismic data and well measurements from the subsurface. This application uses the ... 
A Visual Analytics Dashboard for Mental Health Therapists
(Master thesis, 20190629)Mental health disorders are a significant problem throughout the western world. Cognitive Behavioral Therapy (CBT) is a common treatment form for these disorders. Internetbased Cognitive Behavioral Therapy (iCBT) provides ... 
Abstractions for LanguageIndependent Program Transformations

Accuracy and efficiency of germline variant calling pipelines for human genome data
(Journal article; Peer reviewed, 2020)Advances in nextgeneration sequencing technology have enabled whole genome sequencing (WGS) to be widely used for identification of causal variants in a spectrum of geneticrelated disorders, and provided new insight into ... 
Accurate analysis of genuine CRISPR editing events with ampliCan
(Peer reviewed; Journal article, 2019)We present ampliCan, an analysis tool for genome editing that unites highly precise quantification and visualization of genuine genome editing events. ampliCan features nucleaseoptimized alignments, filtering of experimental ... 
Additive Schwarz preconditioner for the finite volume element discretization of symmetric elliptic problems
(Peer reviewed; Journal article, 20150925)A symmetric and a nonsymmetric variant of the additive Schwarz preconditioner are proposed for the solution of a class of finite volume element discretization of the symmetric elliptic problem in two dimensions, with large ... 
Algebraic Attack on Small Scale Variants of AES using Compressed Right Hand Sides
(Master thesis, 20180407)The Advanced Encryption Standard is probably the most used symmetric encryption cipher in use today, which makes it particularly interesting for cryptanalysis. This thesis attacks smallscale variants of AES through a ... 
Algebraic Cryptanalysis of Cryptographic Schemes with Extension Field Structure
(Doctoral thesis, 20210906)PostQuantum Cryptography studies cryptographic algorithms that quantum computers cannot break. Recent advances in quantum computing have made this kind of cryptography necessary, and research in the field has surged over ... 
Algorithmic Complexity of Clustering and LowRank Approximation Problems
(Doctoral thesis, 20210329)The two most popular unsupervised learning problems are kClustering and LowRank Approximation. Consider a set of n datapoints, in the kClustering problem, the objective is to partition these points into k clusters and ... 
An Algorithmic MetaTheorem for Graph Modification to Planarity and FOL
(Journal article; Peer reviewed, 2020)In general, a graph modification problem is defined by a graph modification operation ⊠ and a target graph property 𝒫. Typically, the modification operation ⊠ may be vertex removal, edge removal, edge contraction, or edge ... 
Algorithms for Linearly Ordered Boolean Formulas
(Master thesis, 20160630)This thesis considers a class of propositional boolean formulas on which various problems related to satisfiability are efficiently solvable by a dynamic programming algorithm. It mainly consists of two larger parts: the ... 
Algorithms for the Rainbow Vertex Coloring Problem on Graph Classes
(Journal article; Peer reviewed, 2020)Given a vertexcolored graph, we say a path is a rainbow vertex path if all its internal vertices have distinct colors. The graph is rainbow vertexconnected if there is a rainbow vertex path between every pair of its ...
