Job Title: Post-doctoral Scientist
Group: Mitochondrial Medicine for Liver Disease
Reporting to: Dr Elena Palma (PI)
Duration: 2 years initially
Annual leave: 27 days per annum
Starting date: November 2024
We are seeking a driven and enthusiastic Post-doctoral scientist to become an integral part of the Mitochondrial Medicine for Liver Disease group at the Roger Williams Institute of Hepatology (RW-IoH). Are you passionate about those amazing organelles? Do you believe the best has yet to come for mitochondria-targeted therapies?
You will be a key team member and together we will elucidate the role of mitochondrial dynamics in liver pathology and develop novel therapeutic strategies to tackle liver diseases (especially alcohol-related liver disease (ALD), liver cancer) or to rescue marginal grafts. Responsibilities will include day-to-day management and coordination of the project with a clear focus on translational medicine. By delving into the pathophysiological role of mitochondria, you will push the boundaries of mitochondrial medicine and develop innovative interventions to tackle the burden of liver disease.
We Are Looking For:
Your Impact:
You will be pivotal in performing and driving forward this research project: data collection and analysis, literature review, manuscript preparation for high-impact publications and grant applications. Additionally, you will have the opportunity to showcase your findings at internal and external scientific meetings/conferences. Acting as mentor and supervisor, you will also guide and inspire junior members of the research team and students.
Why Join Us?
Job Description
Applications are invited for a Post-doctoral Scientist position to join the Mitochondrial Medicine for Liver Disease group, as part of the Roger Williams Institute of Hepatology. Funded by the Foundation for Liver Research, the post-holder will investigate the role of mitochondria and the potential to apply mitochondria-targeted interventions (including mitochondrial transplantation) to reduce the burden of liver disease.
The overall goal of the MitoMed group is to develop novel therapies for Alcohol-related Liver Disease (ALD) and primary liver cancers, employing strategies targeting mitochondria and multipronged approaches (i.e. cyclophilin inhibitors or combinatorial immunotherapies).
The research programme revolves around the following objectives:
Post Specification
The appointed Post-doctoral Scientist will be focussing on the mitochondria-related projects running in the lab (mitochondrial dynamics in ALD, see more details below) according to their expertise and interest.
The post-holder will be expected to work collaboratively and effectively with internal/external collaborators involved in the project and other group members. He/she/they will provide technical support by helping with lab organisation, conducting research experiments, collecting and analysing data, reviewing the literature, writing reports and manuscripts for publication, and presenting their research at internal and external scientific meetings/conferences. The post-holder will be a point of contact for staff and students regarding experimental procedures and techniques for the research area and act as a mentor and supervisor to junior members of the research team and students.
The post will suit an ambitious and highly motivated postdoctoral scientist, or a scientist who have recently been awarded a PhD, who enjoys working as a member of a newly formed team. Furthermore, the post will suit a scientist who wishes to develop their own career and pursue opportunities for independent fellowships in the next few years.
The appointee will be expected to:
Job descriptions cannot be exhaustive and the post-holder may be required to undertake other duties which are broadly in line with the above key responsibilities. The nature of scientific work means it may be necessary to work outside of normal working hours in order to complete an experiment, or to process clinical specimens. An exact breakdown of percentage time spent in different duties is impossible to provide in a scientific job as the exact nature of day-to-day duties will evolve with the project.
The following skills and attributes are required for the post-doctoral position and will be assessed at application and interview stage:

Projects background
Liver disease is currently one of the major causes of mortality and morbidity, as it accounts for the death of more than 2 million people globally every year (Devarbhavi H et al., 2023). Increased alcohol consumption, together with the progressive aging of the general population and the prevalence of metabolic factors, means that mortality is predicted to increase in the future.
A substantial body of literature describes the several direct and indirect effects of alcohol and Alcohol-related Liver Disease on mitochondria (Abdallah & Singal, 2020; García-Ruiz et al., 2013; Nassir & Ibdah, 2014). This mitochondrial dysfunction compromises the survival, function and regenerative capacity of the hepatocytes, with consequent repercussions on liver function as a whole. In addition, we and others have demonstrated that hepatic mitochondria can promptly undergo morphological adjustments in response to ethanol exposure, inducing adaptation or ‘maladaptation’ to this toxic agent as a result, and that mitochondrial dynamics, shape and mitochondria shaping proteins are affected in ALD (Das et al., 2012; D. Han et al., 2012; Palma et al., 2020; Palma, Ma, et al., 2019). Interestingly, the presence of disproportionately enlarged organelles, namely megamitochondria, in liver biopsies of ALD patients has been known since a long time (Chedid et al., 1986). Different clinical studies support the hypothesis that megamitochondria development is a beneficial adaptive response to alcohol and have shown that megamitochondria detection in liver biopsies is one of four clinical and histological parameters associated with a better outcome in terms of survival at 90 or 180 days in patients with alcohol-related hepatitis (Altamirano et al., 2014). Furthermore, investigations in experimental models have demonstrated both beneficial and detrimental effects of megamitochondria in ALD (Ma et al., 2023; Palma, Ma, et al., 2019). As such, a consensus has not been reached and further studies are required to elucidate better mitochondrial dynamics in the context of ALD and investigate the possibility to develop mitochondria-related therapeutic interventions to tackle this disease.
Furthermore, due to the silent nature of liver disease, the diagnosis is usually late and liver transplantation (LT) is still the only curative therapy available for patients with end-stage liver disease. LT has demonstrated remarkable efficacy, offering a near-normal quality of life to patients otherwise deemed for rapid death. Importantly, all newer indications and the success rate of LT have resulted in an unprecedented global demand for liver grafts and the consequent issue of a shortage of transplantable organs raising mortality rates among patients on the waiting list. Many groups have considered the use of previously discarded marginal or extended criteria donor (ECD) livers to overcome the limited availability of organs for transplantation. However, these grafts are at risk of poor function after implantation. In recent years, there has been a growing recognition of the critical importance of mitochondrial function in liver preservation and transplantation (Shi S et al., 2023; Saeb-Parsy K et al., 2021). Mitochondrial transplantation has been proved successful in in-vitro and in-vivo models to treat mitochondrial dysfunction in various tissues, including liver (Shi X et al., 2018; Fu A et al., 2017) and recently a promising study has reported that in an ex-vivo porcine model of renal transplantation, mitochondrial transplantation reduced damage (Rossi et al., 2023). In this future project we would like to apply mitochondrial transplantation for the rescue of marginal or ECD grafts to ultimately tackle the shortage of transplantable livers.
