1. Methodology and Infrastructure for Statistical Computing in Genomics : Applications for Ancient DNA
Sammanfattning : This thesis concerns the development and evaluation of computational methods for analysis of genetic data. A particular focus is on ancient DNA recovered from archaeological finds, the analysis of which has contributed to novel insights into human evolutionary and demographic history, while also introducing new challenges and the demand for specialized methods.

2. Order and Adornment : The Role of Dress in Plutarch
Sammanfattning : This dissertation investigates the role of dress in the ancient Greek author and intellectual Plutarch. The works of Plutarch comprise one of the most prolific authorships preserved to us from classical antiquity. LÄS MER
3. Divergence, admixture and continuity in the human past : Demographic inference using ancient and modern genomes
Sammanfattning : Demographic forces shaping the genetic variation we observe today can include population divergences, admixture events and continuity through time. The advancement of high-throughput sequencing technologies, together with developments in molecular and bio-informatics methods, mean the number of ancient genomes available for inference has risen steeply.

4. Palaeoenvironmental reconstructions from modern and ancient plant DNA
Sammanfattning : Palaeoecological studies on lake sediments and peat archives have provided fundamental knowledge about past environments, nevertheless, a lot remains to be learned. In this thesis, I focussed on plant ancient DNA extracted from sedimentary archives (sedaDNA), in combination with DNA from living trees with the aims of: (1) investigating different extraction methods and levels of inhibition in sediments, (2) investigating postglacial recolonisation history of Norway spruce in Fennoscandia, (3) comparing different sequencing and bioinformatic approaches to investigate past flora changes using sedaDNA and investigating past flora change in contrasting environments (southern Italy versus southern Sweden), and (4) communicating my work more broadly using art.

5. New Roads for an Ancient Enzyme : Whole-Cell Studies and New Cofactors for [FeFe] Hydrogenases
Sammanfattning : [FeFe] hydrogenases rare Nature’s best H2-processing catalysts, and one of the best candidates to satisfy societal need for cheap and efficient catalyst for H2-evolution. These enzymes owe their remarkable catalytic activities to their organometallic active site, called “H-cluster”. LÄS MER
