Overview

Project 6: Legume chemistry and the specificity of pea aphid host races
Supervisors: Prof. Jonathan Gershenzon, Dr. Grit Kunert

The pea aphid, Acyrthosiphon pisum (Harris), is actually a complex of distinct races that each live on a different group of legume species. Some live on several species, while others live on a single species or just a few. This ecological specialization can be considered as one of the first steps towards sympatric speciation since the host fidelity of races leads to assortative mating which reduces gene flow between host-races. The aim of this project is to identify plant chemical compounds that are responsible for the pattern of host plant usage by pea aphid races and test their involvement in ecological and evolutionary processes. We are seeking: a highly motivated Ph.D. candidate with some background in analytical chemistry, biochemistry or chemical ecology. The candidate should be strongly interested in interdisciplinary research questions. (Project leader: Grit Kunert).

Overview
Project 7: How do wood-feeding insects digest their diet? Supervisors: Prof. Jonathan Gershenzon, Dr. Axel Schmidt, Dr. Martin Kaltenpoth, MPI-CE

Wood-feeding insects are sometimes known to use microbial symbionts present in their guts to help in digestion and nutrient mobilization. However, nothing is known about how such insects cope with wood and resin. The large pine weevil, Hylobius abietis, is a serious pest on the bark of young conifer trees in northern Europe that must deal with both wood fiber and terpene-containing resin as major parts of its diet. This project will explore the metabolic fate of resin terpenes in these insects and the role of gut bacteria in processing terpenes and wood at the molecular, protein and metabolite levels. The project combines entomological, microbiological, chemical and molecular biology methods to better understand the lifestyle of one fascinating, long-lived species of insect. Collaboration between Research Group on Insect Symbiosis (Dr. Martin Kaltenpoth) and Department of Biochemistry (Dr. Axel Schmidt).

Graduate Students in Mathematics at Linköpings University

Overview
GRADUATE STUDENT IN MATHEMATICS at the Division of Applied Mathematics at the Department of Mathematics at Linköping University and with Vladimir Kozlov as main supervisor

Research area
The student will work on an interdisciplinary project on study of quantum scattering and conductivity in novel super material graphene aiming at better understanding of the relation between microscopic properties of this material and its macroscopic observed characteristics. The project will be conducted in close collaboration with Igor Zozoulenko (ITN).

Duties
The duties consist of graduate studies and tutorial teaching at most 20 percent of the total work time.
