Sandra dedicates her PhD studies to revolving pancreatic beta cells and its function. These are the only body cells that produce insulin. Beta cells are involved in the task of maintaining homeostasis of a healthy metabolism. Her main method is functional imaging (microscopy) of intracellular calcium. Intracellular calcium is directly coupled to the amount of secreted insulin. Investigating different scenarios by incubating the cells in different solutions and check on the amount of secreted insulin is her daily task, and she spends days, nights and weekends at the microscope. In this special case changing the pH value led to information on the amount secretion.
