Akseli Hemminki received his PhD degree in cancer genetics in 1999 at the University of Helsinki. After three years spent in USA he returned to Finland in 2002 and started his own research group, Cancer Gene Therapy Group (CGTG). He specialized in Oncology and Radiotherapy in 2007. In 2015 Hemminki was nominated as a Professor of Oncology (Jane and Aatos Erkko Foundation donation). In 2017 he received a tenured Professorship of Oncology in Faculty of Medicine, University of Helsinki.
From the beginning CGTG’s main research interest has been oncolytic adenoviruses which destroy cancer cells due to their natural ability to replicate in them, and use them for developing novel treatments for cancers that currently lack curative modalities. In 2007, Hemminki initiated the Advanced Therapy Access Program (ATAP), where 290 advanced cancer patients were treated with ten different oncolytic adenoviruses in an individualized patient-by-patient experimental therapy approach. When evidence of efficacy started emerging, Hemminki founded Oncos Therapeutics Ltd (currently Targovax ASA) to convert the approach to clinical trials.
Human data suggested that the main consequence of oncolysis is actually immune response, directed not only at the virus but also the tumor. Oncolysis can break immunological tolerance at tumors and induce adaptive responses. Particularly prominent is the effect on T-cells. With this information, Hemminki came up with the idea of using oncolytic virus for enhancing adoptive T-cell therapy. Also checkpoint inhibiting antibodies, which have led the mainstream field of immuno-oncology, are in essence T-cell therapy and can be enhanced with our approach. A patent was submitted and Hemminki’s second University spin-out company TILT Biotherapeutics Ltd was founded in April 2013 to support clinical translation, and the first clinical trial is now under way.
Hemminki has trained 38 students and 24 post-docs, and 29 PhD theses have been completed. He has published nearly 300 papers or book chapters on cancer research, treatment and especially oncolytic immunotherapy.

Riikka Havunen works at CGTG as senior researcher investigating oncolytic adenoviruses coding for immunostimulatory cytokines as enablers of T cell therapies. The aim is to study the effects of the viruses on immune system and tumor microenvironment. Riikka graduated as Master of Science from the University of Jyväskylä in 2012, having cell and molecular biology as major. After graduation, Riikka spent two years in the field of cancer research at the University of Tampere. Being interested in translational research, Riikka joined CGTG in 2014. She finalizing her PhD studies and defended in November 2018.

Molecular biosciences have always fascinated Saru Basnet. She has graduated from the University of Eastern Finland with a degree in Molecular Medicine and Genetics. Ever since she had been briefly introduced to the field of cancer studies during her master’s degree, she has been very passionate about cancer research and desired to learn and understand more about it. Eventually, Saru Basnet is a doctoral student at CGTG, specializing in Cancer research. Her research is focused on the oncolytic adenoviral vector encoding a bispecific monoclonal antibody in combination with adoptive T- cell therapies.

PhD, senior researcher
Víctor Cervera-Carrascón got his Master's degree in Pharmacy at Complutense University of Madrid (Spain). During his studies, he already got introduced to the field of oncoimmunology and oncolytic viruses during an Erasmus+ internship at University of Helsinki (Finland). After defending the Master's thesis in February 2016 he joined CGTG and TILT Biotherapeutics as a PhD candidate. He defended his PhD thesis successfully in Feb 2021 and continues now as a post doc in CGTG.
His research revolves around the idea that oncolytic viruses are an interesting tool to enable T-cell therapies, with a special focus on checkpoint inhibitors. As he is enrolled in an European Industrial Doctorate project (VIRION - Marie Skłodowska-Curie actions), he is taking advantage on understanding the links between Academia-Industry-Clinic.

James Clubb received his Masters Degree in Biomaterials & Tissue Engineering from University College London where he completed his research project at the School of Pharmacy in the department of Pharmaceutics. During this time, he became interested in cell and gene therapies which led him to a pursue a role at a startup specializing in generating iPSC derived hematopoietic cells for transfusion medicine in addition to developing a metabolic drug discovery program.
Having wrapped up these projects, in 2019, he joined the Cancer Gene Therapy Group and TILT Biotherapeutics as a PhD student under a Marie-Sklodowska-Curie European Industrial Doctorate program (STACCATO). His project utilizes in vivo models to explore how oncolytic adenoviruses coding immune-modulators can be used to overcome resistance to checkpoint inhibitors in Squamos Cell Carcinomas of the Head and Neck.

Camilla Heiniö has a master's degree in microbiology, with a specialization option in virology. She has a strong background in molecular virology. Before starting her post-graduate studies at CGTG in 2017, she isolated and characterized archaeal viruses. Today, her research focuses on the effects of a cytokine armed oncolytic adenovirus on danger and pathogen-associated signaling and the subsequent consequences the signaling cascades has on the tumor microenvironment. Additionally, the effects of virus-encoded cytokines on the tumor vasculature is investigated in her work.
