Yuri Kogan

Yuri Kogan holds a BA degree in Theoretical Mathematics from the Tel-Aviv University (TAU). Over many years of scientific research at IMBM, he has been involved in biomathematical modelling of several cancer indications, as well as in researching cancer stem cells, intracellular signal transduction, immune system functioning and clinical immunotherapy.

Scientific activity in 2022

During the recent year, Yuri lead the development of the novel algorithm for individual prediction of the immediate deterioration for the hospitalized Covid-19 patients, based on their blood test results. For this project, we have established cooperation with Covid-19 divisions in Sheba Hospital and in Barzilai Hospital, and have obtained real-word patient data for the analysis and model development. Our model employs advanced Machine Learning methods and has retrospectively evaluated ROC AUC metric of 0.75-0.8 tested by cross-validation and independent external validation.  

Scientific activity in 2023

Yuri will focus on modelling the dynamics of immune system, in response to disease. The model will be applied to study response to viral infection, sepsis, and cancer immunotherapy. We will start by creating a population model of the longitudinal dynamics of immune response to Covid-19 infection.
