Tristan Lee Freeman, the science guy!





















So, the veterans are working together on this one. =) This is Tristan. He's a summer II SEED student and he is a senior at Pittsburgh Carrick High School. We've gotten to work with him over the past two summers and believe me, it has been fun. Last year, his project was pretty interesting but, we seem to like his project this year better. We've gotten to spend a good bit of time just hanging out in the lab with him and see what he does.

This year, Tristan is continuing off of last years project. He is using droplet-based microfluidics to create continuous droplet flow using oil and aqueous phases. He is applying ratios to achieve this droplet flow.

In this picture, Tristan is looking into a microscope at a PDMS chip and analyzing the microdroplets flowing through the channel that is chemically etched into the chip. The droplets are formed from t-junction of the aqueous and oil phase. Tristan sets ratios in attempt to achieve the droplet flow that may or may not be successful.
