Dr. Tsoumakidou is a board-certified respiratory specialist, group leader at Biomedical Sciences Research Centre (BSRC) Alexander Fleming and associate professor of Physiology at the Medical School of the National and Kapodistrian University of Athens.  The overarching goal of her studies has been to decipher the landscape of antigen-presenting cells in immune disorders with the aim of identifying new immunotherapeutic targets and advancing novel therapies. Dr Tsoumakidou is emerging as a leader in the field of cancer immunology for her discovery of a novel subset of lung fibroblasts that present cancer antigens and provide survival signals to lymphocytes, refuting the conventional assumption that fibroblasts are immunosuppressive. She proposes a new concept in cancer immunity whereby anti-tumour CD4 T cells require interaction with antigen-presenting cells in tumor tissues, where tumor antigens reside. Dr Tsoumakidou has published over 30 primary papers and reviews as lead author in high-profile journals (>4000 citations, h-index 27 Source: Google Scholar). She has been the recipient of several awards, among which the Clinical and Research Excellence Award by the Hellenic Thoracic Society. Dr. Tsoumakidou's contributions have been primarily centered in Greece. In 2023 she was awarded a Consolidator grant from the European Research Council (ERC) and in 2025 she founded OncoGenesys, which focuses on the development of immunotherapeutics for cancer patients.

Emmanouil Aerakis received his Bachelor’s degree in Molecular
Biology and Genetics from the Democritus University of Thrace in
2018, supported by an IKY fellowship. In 2020, he completed his
Master’s in Molecular and Applied Physiology at the University of
Athens Medical School, graduating with distinction. Since 2021, he
has been pursuing his PhD at the Biomedical Sciences Research
Center "Alexander Fleming" in the group of Professor Maria
Tsoumakidou, supported by an HFRI scholarship. His research focuses
on the spatio-temporal regulation of type I dendritic cells in cancer,
using in vivo and in vitro models, gene-editing techniques, multicolor flow cytometry,
immunofluorescence, and ex vivo human assays. In 2025, he was awarded a Bodossaki
Foundation fellowship and joined the group of Professor Miriam Merad at the Department of
Immunology and Immunotherapy, Icahn School of Medicine at Mount Sinai. He has received
awards at national and international conferences and authored two publications. Since 2025,
he has been working with OncoGenesys as a Molecular Biologist supporting target
validation, assay development, and screening strategies for the company’s drug discovery and
screening pipelines.

Alexios N. Matralis holds a B.Sc. in Chemistry from the University of Patras and both an M.Sc. and Ph.D. in Medicinal Chemistry from the University of Athens. He has over fifteen years of research experience in the development of bioactive molecules targeting multifactorial human diseases such as atherosclerosis, type 2 diabetes, cancer, chronic inflammatory disorders, and malaria. Following his Ph.D., he conducted postdoctoral research at McGill University in Montréal, Canada, where he developed a novel series of senescence-inducing agents for pancreatic cancer, which attracted interest from Merck for further development. In 2017, he joined GlaxoSmithKline as a senior researcher, where he contributed to the development of novel fast-acting antimalarial compounds, currently undergoing advanced preclinical studies. In 2018, Alexios joined BSRC “Alexander Fleming” as a Stavros Niarchos Research Fellow where he led research programs focused on small molecule drug discovery targeting fibrosis, cancer, and inflammatory diseases, including an Individual Research Grant from the Hellenic Foundation for Research and Innovation. Since 2025, Alexios serves as Medicinal Chemist Consultant at OncoGenesys, overseeing the development of novel cancer therapeutics.
