The focus of his current research lies in understanding the impact of preoperative interventions effect on the human physiology and immunology, especially in colonic or rectal cancer. Thus, the field of interest and methodology ranges wide: from epidemiology, pathophysiology, to case control- and clinical randomized studies. We are using a wide range of methods in the studies including physical assessments with Cardio Pulmonary Exercise Testing, Inflammatory markers, transcription analysis and other omics.
