Project Description:
Microscopy allows us to see things that are invisible to the naked eye and image analysis allows us to extract quantitative information from microscopy experiments. This allows us to explore a wealth of information from finding the localization of a protein of interest [1], exploring the dynamics of transcription when a cell is exposed to stress [2], helping us biophysically model how cells attain the right tension to undergo mitosis [3], or even determine the fate of stem cells [4]. Those previous examples are actually just projects I have been involved in- including some during my time as an undergraduate research student! There are still even more diverse microscopy projects throughout many different fields of biology.
Summer research students will do imaging and analysis experiments on a variety of biological systems. Prior experience using a microscope or programming is not necessary. Most image analysis will take place using graphical user interface programs, but some students might also learn some programming.
