I am a graduate student in the Engineering Science and Mechanics department. My focus in research includes spatiotemporal control of chemical and physical cues to probe and understand cellular behavior in microfluidics. Some of my other works include programmable colloidal assembly, micropropulsions using different physics and understanding their behavior at different fluid interfaces. Lastly, I have been putting a lot of effort on single cell force studies.
