天然蛋白质经过亿万年的进化精巧地解决了自然界中各种复杂的问题，但是当今世界在健康、环境和能源等不同领域仍面临迫切需要解决的新的挑战。我们实验室旨在利用计算方法设计具有不同功能的全新的人工蛋白质来应对这些挑战。蛋白质计算设计是现在国际上生物医药领域的跨学科热门研究方向之一，成为各大制药公司的重点投资对象，同时也吸引了传统信息技术公司的浓厚注意力。深度学习算法在蛋白质结构预测中取得的革命性突破更将会有助于蛋白质计算设计新一轮的变革式开展。蛋白质计算设计不仅在生命健康领域有着广阔前景，它同时也可以和合成生物学相结合在环境与能源方面具有巨大应用的潜力，但是它在国内尚属亟待开发的新兴学科。

我们实验室将着眼于开发新的蛋白质计算设计方法并探索全新的功能性蛋白在不同研究领域中的应用，主要研究方向包括：

1. 开发基于深度学习算法的新的蛋白设计方法；

2. 设计可用于基础研究和疾病诊疗的蛋白质器件；

3. 设计新型蛋白质酶以应对环境与能源危机。

Proteins, directed by evolution, have elegantly solved a vast array of technical problems in nature. However, new challenges emerge in different aspects of our changing world, such as health, environment, and energy. Our laboratory aims to design new classes of functional proteins using computational algorithms to address these challenges. Computational protein design is one of the multidisciplinary research areas that has attracted substantial attention from pharmaceutical companies and technology giants in recent years. Deep learning algorithms have made breakthrough achievements in protein structure prediction, which bring our world to the verge of a protein design revolution. Computational protein design has the promise to transform biomedical research and the potential to tackle environmental and energy crises by integrating with synthetic biology methodologies, but it remains an emerging field of study in China.

Our laboratory will develop new computational protein design methods and explore the applications of de novo designed proteins in numerous research areas. The primary research directions in our lab include

1. developing deep-learning-based protein design approaches;

2. designing functional protein devices for basic research and disease therapeutics and diagnosis;

3. designing novel enzymes to address environmental and energy crises.
