Last summer, I was offered a precious opportunity to attend Strata Data Conference in Beijing as a member of THU data research group. Lectures about big data, cutting-edge data science and business analytics gave me access to true front-end data application. Popularization of data science brought new tools for supporting strategy development. The implement of data in real world aroused my strong interest in supporting strategy with data analytics. Besides reviewing research after the meeting, I started to apply the knowledge and techniques into academic practice, sharing insights and thoughts on my personal website: zchi1.com.
Along this self-studying process, I contacted professor Guo to explore the further possibilities of data implement in my major, who was focusing on IT technology implement in construction industry and urban studies. Statistical computing is prevailing in urban studies realm for analyzing human behaviors. Utilizing social network dataset from Stanford Network Analysis Program, we modeled the displacement distance distribution with Lévy flights, which stands for the random walk with steps following truncated power-law distribution. Beta value of Lévy flights was understood as crowd concentration, shifting significantly during earthquake, providing an important measuring method for disaster prevention and detection. I am now working on my thesis ‘Using social data to analyze the disaster impact on human mobility’ for publishing on SCI journal <Natural Hazards>.
I participated in several research groups during academic study. One of them was development of fluorescent turn-on probes for hydrogen sulfide, which was a signaling molecule of numerous diseases. My duties in this experience was developing probes through a series of reactions. One major challenge was getting satisfied probes and examining various properties of them through complicated chemical reactions. In order to achieve the goal,I did dozens of experiments to approach the sensitivity and selectivity requirements. Although we accomplished a successful project and this could be a significant experiment if it would apply to clinic medicine in the future, my part of work was limited to an isolated area. Lack of macro broad view of the whole research or engineering process will be a limitation for me. The more experiments and researches I did, the stronger this presentiment grew. As a result, I was eager to find a way to widen my view and future path.
