Research

We develop methods and tools for information retrieval, knowledge representation, model inference, and analysis of complex systems. Our goal is to understand and explain the behavior of these systems, predict their responses to external influences or internal perturbations, and recommend new interventions and designs. Leveraging advancements in neuro-symbolic artificial intelligence, we aim to understand, explain, and design complex dynamic systems in the presence of uncertainty, perturbations, and conflicting information. We study biological systems such as immune system, cancer microenvironment, and infectious diseases, as well as combined social, economic, political, and agricultural world systems. Our interdisciplinary lab includes members with backgrounds in electrical and computer engineering, bioengineering, mechanical engineering, computer science, computational biology, physics, and biology.  

DySE - Dynamic Systems Explanation Framework

 

The amount of data and information produced by experimental laboratories studying complex biological systems is increasing at an incredible rate and is being disseminated at a growing number of publishing venues, scattering the knowledge and limiting the effectiveness and feasibility of manual analysis of all available information. This highlights the need for automated methods to retrieve and connect related pieces of the extensive yet fragmented collective knowledge, for the purpose of understanding, interpreting, explaining, and predicting the behavior of studied systems. To address this challenge, we have developed a tool suite, DySE.   With DySE, we aim to integrate natural language processing, information retrieval, and artificial intelligence with assembly, inference, verification, and analysis of computational to enhance understanding and enable efficient interventions in complex systems. With DySE, we study the interplay between the immune system and diseases, including T cells, macrophages, glioblastoma multiforme stem cells, pancreatic cancer, melanoma, colon cancer, and ovarian cancer. DySE is featured in DARPA’s World Modelers program, where it assists decision-makers in identifying key points of intervention in complex world systems.
