Sargassum ocean Sequestration of Carbon (SOS Carbon)
A vessel to intercept and sink invasive sargassum seaweed in Caribbean. Now an active company (soscarbon.com) in the Dominican Republic.
LITTORAL COLLECTION MODULE (LCM)
Low-cost, rapidly scalable sargassum collection device retrofits onto any small boat and allows collection of sargassum before it makes landfall. Local fishermen can participate in cleanup, services can be extended beyond tourism to civilian beaches, and avoiding sand-contamination allows many types of valorization of collected sargassum. This device matches the collection capacity of larger conveyor-based collection barges (at a fraction of the cost and lead-time) and has a flat marginal cost of <$1/m3, allowing cleaning all day (cleaner beaches!).

energy deficit associated w/ lane # in track & field
Project attempted to quantify the energy deficit associated with lane assignment in the 200m and 400m events in Track and Field. There has yet to be a sufficiently technical study, which measures the physical effects of lane assignment at appreciable speeds. The goal of this project was to determine the relationship between the curvature of different lanes and the force and body lean required to maintain running speed. The results of this project show that at a speed of 9.0 m/s the body lean and average force application of the subject varied by 6.34° and 76.3 N, respectively, from Lane 1 to 6, and this difference is positively correlated with running speed. These results call for further investigation and consideration of systemic changes to the sport of Track and Field.
Flow CYTOMETRY METHOD TO DETECT INSULIN SENSITIVITY
Summer program in Bangkok, Thailand and under the umbrella of Professor Dr. Her Royal Highness Princess Chulabhorn Mahidol's Laboratory of Natural Products. I learned column chromatography, high performance liquid chromatography (HPLC), nuclear magnetic resonance (NMR; 1H & 13C), fluorescence microscopy, gel electrophoresis, and developed a flow cytometry method for detecting insulin sensitivity. We used this method to confirm the efficacy of an extract from Gynostemma Pentaphyllum (GP), a component of a popular Ginseng tea, on insulin signaling in human HepG2 cells.
