Funded PhD Project (Students Worldwide)
About the Project
Recent observations of protoplanetary disks reveal that substructures in the dust distribution of protoplanetary disks are common. These substructures show different forms, prevalence, locations, scales, and amplitudes around stars with different properties, such stellar luminosity and age (Andrews 2020). Although planet-disk interaction is a popular explanation for the origin of these structures, there are several theoretical alternatives and currently the real origin remains unknown (Pinilla & Youdin 2017), and planets have been only found in one protoplanetary disk (Keppler et al., 2018). The purpose of this project is to use chemical models together with hydrodynamical and dust evolution models as crucial keys to differentiate between all these models for the origin of the observed substructures. This research is timely with the incoming data from ALMA (MAPS large proposal), which aims to map the chemical structures (around 25 atomic and molecular lines), and constrain the properties of the gas reservoirs on planet-forming scales, in a variety of protoplanetary disks.
Parametric studies of disk chemistry with simple prescriptions of gas and dust have shown that depletions of dust and gas make those parts of the disk more transparent to stellar and external radiation (UV and X-rays), and therefore these regions become warmer. This will have a direct influence on the locations of the ice lines of different abundant volatiles, such as water and carbon-monoxide, and as a consequence it will also affect the composition of the planets forming within these disks. Contrary, the regions where particles concentrate, the disk temperature decrease and some volatiles are sequestered in the grains (Facchini et al., 2018, Alarcón et al., 2020). Current chemical models have only explored in detail the case of planet-disk interaction with several simplifications. In this thesis, we will explore the effect of different origins of pressure bumps in the disk, including planets, dead zones, zonal flows, and vortices. We aim to understand how the nature of such pressure bumps (when they form, how long they live, amplitude, location) affects the gas and dust distribution, the disk temperature and the chemical abundances of several volatiles in protoplanetary disks. We place interest on particular atomic and molecular lines. For instance, the carbon-to-oxygen ratio is one of the few planetary properties which can provide useful information on the formation history of a planet and it can be measure both in planets and disks (e.g., Madhusudhan et al., 2012, Bergin et al., 2016).

About the Project
Our School
Based in the central campus at the University of Edinburgh, the Business School seeks to set the agenda across a wide range of business disciplines, with our research areas staffed by teams whose work has real influence in business, government, and the public sector.
The University of Edinburgh is ranked 4th in the UK for research power, and the Business School has over 100 years of research experience. We aim to provide a highly dynamic and supportive research environment for our large and diverse graduate community, ensuring that our doctoral students have the resources required to make the most of their individual projects.
Scholarship details
We are offering six fully funded scholarships, one within each of our main subject areas:
·Accounting & Finance
·Entrepreneurship & Innovation
·Marketing
·Management Science & Business Economics
·Organisational Studies
·Strategy
The majority of subject areas have highlighted key themes where they are focusing their research development. While each group will consider applications from any topic which falls within their research area, applicants whose proposal falls within a highlighted theme will be given preference. Full details of the various themes can be found on our School website here.
Eligibility
Applicants must meet the following requirements:
Programme Offer: All candidates must hold a conditional or unconditional offer onto one of our Doctoral programmes and expect to join in September 2021. While you can be awaiting an application outcome when applying for this scholarship only those with an offer can be considered.
Academic Standing: This normally requires a minimum qualification (or expected qualification if you are a current Master's student) of above-average academic achievement, typically 65% or above overall at the Master's level, with a distinction-level dissertation.
English Competency: You must meet the English requirements for the PhD in Management, PhD in Accounting, or PhD in Finance. The most commonly approved certificate is an IELTS, for which the minimum accepted score is 7.0 overall with at least 6.0 in each section.
How to Apply
To access the scholarship application you must first complete your programme application.
When submitting your scholarship application, please apply to one (or more) of the following opportunities:
Accounting & Finance Group Doctoral Scholarship

Deadline
The deadline to apply is 23:59 (UK time) on the 24th February 2021.
Candidates will be notified of the outcome of their application in April 2021.
Value: Full tuition fees (UK or Overseas level) with £15,500 annual stipend for up to 4 years. The award will be pro-rata for part-time students.

Pathways to a carbon neutral livestock industry by 2030University of Tasmania | Tasmanian Institute for AgricultureSupervisor：Assoc Prof M HarrisonApplication Deadline：Friday, February 12, 2021Funded PhD Project (Students Worldwide)
The project will explore the nexus between profitability, sheep and beef productivity, greenhouse gas mitigation and carbon sequestration of livestock businesses in an increasingly variable climate. The successful candidate will be required to conduct an integrated assessment including farm case studies in regions throughout Australia.
The study will identify farming systems adaptations that are profitable, environmentally sustainable and targeted towards future market opportunities, with particular emphasis on pathways to a carbon neutral red meat sector by 2030. Adaptation options will explore pasture feedbase options (e.g. new legumes and grasses), animal genetics (e.g. low methane genotypes), new technology (e.g. virtual fencing) and management options, as well as options to capture value from emerging carbon markets.
Through computer modelling and work with farmers, the project will inform future research and development investment in grazing systems with higher resilience to climate change and challenges across Australia. The project will provide a series of farm systems that can be used to either demonstrate or research options to raise profitability and mitigate whole farm GHG emissions under a changing climate.
Funding:
A living allowance scholarship of $28,092pa (2020 rate) as well as a fully-funded tuition scholarship will be considered for an outstanding applicant. The scholarship duration is 3.5 years, with no extension.
Eligibility:
The candidate must have an Honours Class 1, Masters by Research (or equivalent) and have undertaken an IELTS test within the last 12 months. Applicants must have an IELTS score of 6.5 or above.
After COVID-19 travel restrictions ease, the candidate will be required to relocate to Tasmania, Australia, for the duration of the PhD.
