Marie-Catherine Vozenin
CHUV, Switzerland
Organizer of the 2nd FLASH Workshop

The research projects that I develop with my team aim at finding innovative tools able to protect normal tissue and enhance tumor control. In this context, we have developed a novel modality of radiation therapy called FLASH-Radiotherapy that minimizes normal tissue toxicity and eradicates tumors in various organs including the brain, lung and skin and in various species including mice, zebrafish, pigs and cats. Much of our recent work has focused on investigating the entirely different biological response induced after FLASH exposure. Importantly, we have worked to secure the translation of FLASH-RT into clinical trials for human patients with cancer.

Charles Limoli
University of California, USA

One of the main goals of my research program is to advance FLASH radiotherapy from the bench to the clinic. To this end, we have been successful in obtaining NCI funding for a program project grant aimed to characterize this novel irradiation modality that challenges some of the most fundamental tenets in radiobiology. FLASH radiotherapy is able to achieve remarkable improvements in therapeutic gain through ultrahigh dose rate (≥ 100 Gy/s) delivery. My team that includes Marie-Catherine Vozenin at the CHUV in Switzerland, Bill Loo at Stanford University, Peter Maxim at Indiana University and Doug Spitz at the University of Iowa have generated data in support of several mechanisms, of which one involves a mechanism that minimizes radiation-induced oxygen toxicity and exploits the differential redox biology between tumors and normal tissue. While tumor cure is iso-efficient between FLASH and conventional dose rate modalities, FLASH induces transient and radioprotective hypoxia that affords significant sparing of normal tissue injury in the brain (and throughout all other organs analyzed). Collectively, my research strives to generate the requisite data necessary to facilitate the rapid implementation of this innovative irradiation platform, using both electron and X-ray beams, into the clinic.

Lara Barazzuol
University of Groningen, the Netherlands

Lara Barazzuol obtained her PhD in Radiation Biology in 2012 at the University of Surrey in the United Kingdom. She then held a 3-year postdoctoral position at the Genome Damage and Stability Centre, United Kingdom, in Professor Penny Jeggo’s laboratory, known for their world-leading research in DNA repair. This is where Lara developed her research interest of how the embryonic and adult brain respond to DNA damage. In September of 2016, Lara moved to the University Medical Center Groningen (UMCG) in the Netherlands to establish her own laboratory within the Department of Biomedical Sciences of Cells and Systems and the Department of Radiation Oncology.

Highlights from her career to date comprise several peer-reviewed articles and young investigator awards, including the 2012 Mercia Award in Medical Engineering, the 2015 British Institute of Radiology Nic McNally Award, the 2017 Adrian Begg Award and the 2017 Bas Mulder Award. Since 2016, Lara became a committee member of the British Association of Radiation Research. She is currently project leader on grants from ZonMW and KWF (Dutch Cancer Society).

Lara Barazzuol’s research focuses on assessing the effect of cancer treatment, radiotherapy and chemotherapy, on the brain. Her group primarily aims to achieve an improved understanding of radiotherapy-induced neurocognitive dysfunction. When using radiotherapy in the treatment of brain tumours, damage of normal brain tissue is an unavoidable side effect. This can severely compromise cancer patients’ quality of life by diminishing their neurocognitive function, especially in cases of childhood brain tumours. Similar neurological effects have also been seen after chemotherapy treatment for brain, but also non-intracranial, tumours. The underlying mechanisms are not fully understood and, at present, there is no effective treatment.

Lara Barazzuol’s lab, by using a combination of methodologies, including cerebral organoids and in vivo models, aims to understand the underlying biological mechanisms of cancer treatment-induced neurocognitive dysfunction; and, to investigate how genetic variation might contribute to neurocognitive outcome.

Her group is also interested in investigating how defects in DNA repair impact on human health, with particular focus on neurodegenerative diseases.

Stefan Bartzsch
Technical University of Munich, Germany

Dr. Bartzsch studied physics at the University of Jena. He received his PhD at the University of Heidelberg in the field of medical physics and worked as a Postdoctoral Research Fellow at the Institute of Cancer Research in London. End of 2016 he moved to the “Klinikum rechts der Isar” of TUM and is leading an independent research team at the Helmholtz Centre Munich in the Institute for Radiation Medicine since 2018.

Dr. Bartzsch (*1986) conducts research in the field of experimental medical physics. Focus of his research is microbeam radiation therapy, an innovative treatment approach, which treats tumours with micrometer sized radiation field. This still preclinical method promises a substantial reduction of side effects known from conventional radiation therapy. In this interdisciplinary area of research, Dr. Bartzsch and his team develop novel x-ray sources and investigate the radiobiological causes for the efficacy of microbeam radiation therapy.

Arnab Chakravarti
The Ohio State University, USA

I am professor and chair of the Department of Radiation Oncology at The Ohio State University, where I also hold the Klotz Chair in Cancer Research and direct the Brain Tumor Program. I was named to the Castle Connolly list of “America's Top Doctors” from 2012-2019.

A member of the Translational Therapeutics Program at the OSUCCC – James, I focus on translational cancer research to identify novel biomarkers that are predictive of treatment efficacy and survival, and to uncover molecular and genetic mechanisms of treatment resistance to advance care of cancer patients. Under my leadership with the National Cancer Institute-supported Radiation Therapy and Oncology Group Brain Tumor/NRG Translational Research Subcommittee and Brain Tumor Committee, my team’s studies have defined the standard of care for patients with central nervous system (CNS) tumors.

My lab was among the first to report that the dysregulation of PI3K/AKT signaling is associated with radiation resistance in glioblastomas. It also was the first to identify that dysregulation of PI3K signaling is significantly associated with adverse clinical outcomes in GBM patients. These findings led to some of the first clinical studies to combine radiotherapy with kinase inhibitors targeting this pathway.

Additionally, I have published more than 120 articles in leading scientific and medical journals, including The New England Journal of Medicine, Journal of the American Medical Association, Cancer Cell and Journal of Clinical Oncology. I have delivered numerous distinguished lectureships in the United States, Asia and Europe on cutting-edge therapies for cancer patients and have received more than two dozen national and international awards for outstanding clinical care and landmark research accomplishments.

My approach is to personalize cancer care by investigating strategies that are most effective to individual patients through genetic and molecular profiling instead of using the “one glove fits all” approach that is more commonly used in cancer care. In Ohio State’s cancer program, we appreciate that every patient is unique and requires targeted strategies for optimal personalized care.
