cholesterol • intracellular trafficking • cell biology • microscopy
My research focuses on how the body generates the so-called "good cholesterol" or HDL. High levels of good cholesterol prevent heart attacks, while low levels contribute to heart attacks. I study the way that a cell makes HDL and transports the cholesterol into HDL. I am also interested how liver cells store fat. The liver is an extremely important organ for controlling many aspects of metabolism in the body. When the liver gets harmed by storing too much fat, many processes are upset including those regulating sugar use. So, too much fat leads to diabetes. I want to prevent that, so my work focusses on finding how the liver cells can be prevented from being overloaded with fat.
