His primary scientific interests are in Ecology, Obesity, Dissolved organic carbon, Demography and Ecosystem. Particularly relevant to Weight loss is his body of work in Obesity. His studies deal with areas such as Prospective cohort study, Surgery, Quality of life and Epidemiology as well as Weight loss.
His work in Epidemiology covers topics such as Case-control study which are related to areas like Weight Loss Surgery, Gastric bypass surgery and Observational study. His study in Dissolved organic carbon is interdisciplinary in nature, drawing from both Hydrology and Mineralization. His Demography research includes elements of Endocrinology, Gerontology, Weight gain and Three-Factor Eating Questionnaire, Emotional eating.
The scientist’s investigation covers issues in Ecology, Dissolved organic carbon, Pelagic zone, Ecosystem and Obesity. His research in Dissolved organic carbon intersects with topics in Permafrost and Aquatic ecosystem. His work carried out in the field of Pelagic zone brings together such families of science as Trophic level and Food web.
His Obesity research includes themes of Body mass index and Physical therapy. Weight loss and Surgery are frequently intertwined in his study. He has researched Surgery in several fields, including Mental health, Gastric bypass surgery and Depression.
Jan Karlsson mostly deals with Ecology, Dissolved organic carbon, Boreal, Carbon dioxide and Permafrost. His is involved in several facets of Ecology study, as is seen by his studies on Phytoplankton, Pelagic zone, Zooplankton, Aquatic ecosystem and Ecosystem. His Dissolved organic carbon research is under the purview of Environmental chemistry.
The Carbon dioxide study combines topics in areas such as Carbon cycle and Methane. His Permafrost study combines topics from a wide range of disciplines, such as Arctic, Peat, Hydrology, Wetland and Physical geography. His Physical geography research integrates issues from Climate change and Subarctic climate.
His main research concerns Carbon dioxide, Dissolved organic carbon, Ecosystem, Permafrost and Boreal. His Carbon dioxide study integrates concerns from other disciplines, such as Atmospheric sciences, Carbon cycle, Greenhouse gas and Methane. The concepts of his Dissolved organic carbon study are interwoven with issues in Nutrient, Colored dissolved organic matter and Global change.
The subject of his Ecosystem research is within the realm of Ecology. His biological study spans a wide range of topics, including Hydrology, Wetland, Transect and Physical geography. The study incorporates disciplines such as Peat and Organic matter in addition to Boreal.
