我们采用机器学习和信号处理等方法对蛋白质结构和功能进行了深入研究。如蛋白质结构域、甲基化位点、磷酸化位点、蛋白 - 蛋白的结合亲和力和单氨基酸多态性与疾病的关联等。另一方面，我们将化学计量学方法应用于分子动力学模拟和光谱解析。此外研究还涉及到药物不良反应的预测，疾病相关基因的识别，microRNA前体的识别，microRNA与mRNA相互作用。针对各种生物问题，我们在特征的选取和利用以及模型的替代上积累了较丰富的经验。采用蛋白质的序列信息实现了对蛋白质域和蛋白质甲基化位点的预测；利用相互作用信息（蛋白-蛋白相互作用面特征，域-域相互作用，药物-靶标相互作用）构建的预测模型均取得了较好的结果（“典型蛋白质结构功能信息的数字化表征”, 2014年度教育部高等学校自然科学2等奖）。

在算法方面，本课题组不断尝试对各类算法的应用和改进。提出了基于特征值转换的数学方法用于药物靶标的预测；用于药物不良反应预测的新的统计算法；基于模拟退火优化的网络社区划分方法用于人类细胞信号网络的研究和分析。
