Postdoctoral Scholar
Grossberg Lab
Oregon Health and Science University

I am a third year postdoc at Oregon Health and Science University in Portland, OR. I am working in the lab of Dr. Aaron Grossberg, and studying the interactions of central liver metabolism and muscle wasting in pancreatic cancer associated cachexia. I became interested in cancer cachexia over 7 years ago while completing my PhD at the Mayo Clinic School of Biomedical Sciences, in the lab of Dr. Jason Doles. My thesis focused on the response of muscle stem cells to tumor-derived factors in cancer cachexia. I received my PhD in Biochemistry and Molecular Biology in 2021. Prior to that, I completed my Bachelor’s of Science degree at the University of Wisconsin-Superior in 2016. I aspire to have an independent academic research career focused on improving the quality of life, from diagnosis through cancer survival, of patients with cancer cachexia, and understanding the interorgan metabolic events that drive cancer cachexia. I am passionate about mentoring students, and I am committed to making the lab welcoming and supportive for scientists of all backgrounds.

Marc Beltrà, PhD

Postdoc Researcher
Zorzano Lab (IRB Barcelona)

I am a postdoc conducting research on the role of mitochondrial dynamics and autophagy in the development of liver metabolic diseases. As a predoc fellow in Dr. Paola Costelli’s lab (University of Turin, Italy) I characterized the dysregulation of sncRNAs (including miRNAs) in circulating microvesicles and the skeletal muscle during cancer cachexia. In parallel, I also studied the relevance of PGC-1α in modulating muscle stem cell fate. Following my PhD defense, I enrolled as a postdoc researcher in a project directed by Dr. Fabio Penna (University of Turin) focused on ameliorating muscle wasting and mitochondrial dysfunction in cancer cachexia by targeting NAD metabolism. In January 2023, I became part of Dr. Antonio Zorzano’s lab (IRB Barcelona, Spain) after being awarded two individual grants: a Fellowship for Abroad Post-Doc (Fondazione AIRC) and an MSCA Postdoctoral Fellowship (Horizon Europe). Currently, I am investigating the involvement of FATP2 in autophagosome formation in mitochondria-associated membranes and its relevance during the transition from non-alcoholic steatohepatitis to hepatocellular carcinoma.

Leo R. Brown, BMedSci (Hons) MBChB PGCert MRCS

PhD Fellow /
Specialty Registrar in General Surgery Cachexia Group at University of Edinburgh

I am a final-year PhD fellow at University of Edinburgh working under the supervision of Mr. Richard Skipworth and Professor Steve Wigmore. The focus of my research is ‘staging the host’ – the application of clinical features of the cachexia, as an adjunct to tumour stage, for risk stratification and prognostication in patients with cancers of the upper gastrointestinal tract. I have been supported in my research by the Maurice Wohl Research Fellowship from the Royal College of Surgeons (Edinburgh) and charitable grant funding. At present, I am running two observational trials: first attempting to holistically and longitudinal characterize cachexia in patients with a curatively treated malignancy, and second evaluating the use of a novel form of MRI imaging to assess muscle for features of cachexia. I also have an interest in data science and the effective use of routinely collected clinical data. In August 2024, I will return to clinical practice and finish my specialty training working towards a career as an academic oesophagogastric cancer surgeon.

Aneesha Dasgupta, PhD

Assistant Research Professor
Jason Doles Lab
Indiana University School of Medicine, IN, USA

I am born and raised in India. In 2014, I joined the PhD program in the University of Nebraska Medical Center, Omaha. My PhD dissertation under Dr. Pankaj Singh was understanding molecular mechanisms of cachexia. In 2019, I joined the laboratory of Dr. Jason Doles at the Mayo Clinic, Minnesota as postdoctoral fellow. The first project that I started was to develop translational pre-clinical models of cachexia. Using age as a contributing factor in models, we discovered targets that might have been obscured in other models of cachexia. Serendipitously, I discovered a novel tumor promoter Perp, which is also upregulated in cachectic muscles, potentially making it a dual target for cancer and cachexia. My current efforts are based on elucidating the role of Perp in the tumor and muscles and then developing small molecule inhibitors for Perp. One of my major interests is also studying tumor-muscle crosstalk. My ongoing work is based on elucidating the changes occurring in tumor biology as a consequence of muscle wasting. In 2022, our lab moved to Indiana University School of Medicine, and I am currently an Assistant Research Professor in Dr. Jason Doles’ lab. My long-term goal is to be an independent investigator studying tumor-muscle crosstalk and rethinking the ways we model cachexia. I am committed to working towards increasing inclusion and belonging in academia via actionable items, which would also be the foundation of how I lead/mentor trainees in my independent lab in the future.

Luca Delfinis, MSc

PhD Candidate
Christopher Perry Lab
York University
Muscle Health Research Centre

I am a 4th year PhD student interested in the relationship between mitochondria and skeletal muscle health in cancer cachexia. My PhD projects explore the relationships between mitochondrial function and muscle weakness across cancer progression in both colorectal and ovarian cancer preclinical models. In these models, we have found muscle weakness often precedes muscle atrophy and is associated with mitochondrial bioenergetic stress. In my final project, we plan on targeting early mitochondrial bioenergetic stress with mitochondrial-targeted therapeutics in an attempt to delay the onset of cachexia and improve early muscle weakness.

Ross Dolan, PhD FRCS

NES/CSO Clinical Lecturer in Surgery –
University of Glasgow
Honorary Specialty Registrar in General Surgery –
West of Scotland Deanery

I am currently a final year surgical registrar and CSO/NES Clinical Lecturer at the University of Glasgow with an interest in the tumour/host interaction. I have previously worked as a research scientist having completed my initial degree in Neurosciences in Trinity College Dublin before taking up a position as a research biochemist in the Royal College of Surgeons of Ireland in the epilepsy research group. I completed my medical training in the University of Dundee before completing my PhD under the supervision of Professor Donald McMillan and Professor Paul Horgan at the University of Glasgow. My PhD focused on the association between tumour metabolic activity, systemic inflammation, body composition and outcomes in patients with cancer. My current research continues my interest in the tumour/host interaction with an aim of establishing a plausible and targetable relationship between tumour inflammatory signalling, tumour meiosis/genetic instability, systemic inflammation and body composition in patients undergoing operable treatment for colorectal cancer. This could allow for the identification of new therapeutic targets as part of a multimodal treatment strategy for patients with cancer cachexia.

Francielly Morena Clark

PhD Candidate
Nicholas P. Greene’s Laboratory

I am a fourth-year Ph.D. candidate broadly interested in unraveling mechanisms behind muscle impairments in cancer-induced muscle loss. My dissertation focuses on targeting mitochondrial processes previously found altered in pre-clinical models of cancer cachexia, such as mitophagy and fusion, through genetic mouse models and myoAAV gene delivery strategies to mitigate muscle loss in cancer. Recently, following a data-driven curiosity, I established a collaboration with Dr. Karyn Esser from the University of Florida to explore the implications of muscle clocks in muscle health regulation in a cancerous environment. My long-term aspiration is to evolve into an independent academic investigator, committed to advancing efficacious therapies against the complex muscle disarray observed in cancer cachexia.

Ben T. Murphy

PhD Student
Professor Ken O’Halloran’s Lab
Department of Physiology
University College Cork

I graduated with a BSc in Sport and Exercise Sciences from the University of Limerick in 2018 and an MSc in Exercise Physiology from Loughborough University in 2020. I am currently undertaking my PhD studies at University College Cork under the supervision of Professor Ken O’Halloran and Dr John Mackrill. I am interested in the pathology of skeletal muscle atrophy, and in particular the pathophysiology underlying age-related and cancer-related muscle wasting. Coupled with this is my intrigue as to the mechanisms responsible for skeletal muscles adaption to exercise, and how understanding of these mechanisms can inform therapeutic implementation of exercise to combat disease. My PhD studies are focussed on exploring the benefit of exercise as an intervention in novel translatable mouse models of cachexia with a future view to the adoption of strategies for implementation in people with cancer.

Clodagh Scannell

Registered Dietitian/
PhD candidate

I am a PhD researcher working with the Clinical Nutrition and Oncology Research group led by Professor Aoife Ryan, based at University College Cork, Ireland. My research focuses on identifying malnutrition in ambulatory oncology patients using body composition assessments particularly CT analysis. I have expertise in the running of nutritional intervention trials with oncology patients examining the impact of novel nutritional supplements on body composition, inflammation status, quality of life and systemic anti-cancer treatment tolerance. I have also been involved in the development of evidence-based patient resources which aim to improve nutrition knowledge in those diagnosed with cancer and improve patient outcomes. I have a keen interest in the use of biologically based complementary and alternative medicine in those diagnosed with cancer and have conducted research to quantity the use of these products and practices in Irish cancer survivors. Once finished my PhD I hope to continue my research in the area of nutrition and oncology as a Postdoctoral researcher.
