报告题目：Harnessing “Natural” Algorithms For Resolving Problems In Molecular and Biomolecular Engineering

时 间：2018年8月10日（星期五）15:00-16:30

地 点：格致楼3016会议室

摘 要：

Nature has given rise to a variety of algorithms resulting in the development and evolution of populations of objects, entities, and even processes of extraordinary sophistication and complexity. If one can understand the basis on which these “natural” algorithms operate, the potential exists to harness this force. Such knowledge can provide us with a better understanding of the world around us. Additionally, one could use the insights gleaned to design and engineer items ranging from electronic devices to novel materials to recombinant organisms. The potential for these algorithms to be applied in this way has been recognized computationally in the form of artificial neural networks, particle swarm optimization, and evolutionary algorithms such as genetic algorithms to name just a few examples. Our group has attempted to take advantage of these natural algorithms in a variety of ways. Over the course of this talk, I will share some of our efforts in two areas. The first area is that of biomolecular engineering focusing on the use of genetic algorithms in genome-scale metabolic engineering. Specifically, we show how a genetic algorithm may be used to curate metabolic models. We will further go on to show how, by using such an approach, we were able to discover a new gene. The second area will focus molecular engineering, specifically computational analysis and design of materials. Here we will discuss how adding chemical descriptors in machine learning algorithms to characterize metal organic frameworks resulted in significant increase in accuracy of predicting material properties while reducing simulation time by several orders of magnitude.
