Research Interests

My long-term research intersts span artificial intelligence (especially machine learning, causal inference, knowledge representation), computer science, data sciences, cognitive and brain sciences, and applied informatics (especially bioinformatics, health informatics). My research is driven by fundamental scientific questions or important practical problems in areas of societal or national priority (e.g., health):

  • How can we efficiently build predictive models from “big data”)?
  • How can we elicit causal relations from disparate observational and experimental studies? How can we ensure that AI systems are fair, explainable, and accountable?
  • How can we build predictive models from richly structured (e.g., sequences, images, networks), multi-modal (multi-view), and longitudinal data?
  • How can computational abstractions of scientific artifacts and processes mediate scientific collaborations that transcend disciplinary and organizational boundaries and accelerate science?
  • How can we efficiently represent and reason about preferences to support individual and collective decision making? How can we query and reason with federated data and knowledge bases, including those that contain sensitive data or knowledge?
  • How can we learn to predict health outcomes and perform interventions from clinical, biomedical, environmental, socio-demographic, behavioral, and other types of data? How can we predict protein-protein, protein-RNA, protein-DNA interactions, interfaces, and complexes?
  • How can we construct, compare and analyze multi-scale, models of molecular networks that orchestrate cellular development, differentiation, immune response, etc.?
  • How can we model, construct, compare, and analyze brain networks to discover features of fMRI-derived brain networks that characterize functional differences associated with aging, development, and disease?
  • How can we build robust intelligent agents that incorporate multiple facets of intelligence to augment and extend human intellect and abilities?

My research contributions have spanned Artificial Intelligence, Data Science, Machine Learning, Knowledge Representation, Causal Inference, and applications in Bioinformatics, Health Informatics, Social Informatics, Brain Informatics, Security Informatics, and Cognitive Science. Some of my most recent work has focused on:

  • Scalable algorithms for building predictive models from large, distributed, semantically disparate data (big data) 
  • Algorithms for constructing predictive models from sequence, image, text, multi-relational, graph-structured data
  • Algorithms for building predictive models from high dimensional data using feature selection, feature abstraction, and representation learning
  • Methods for selective sharing of knowledge across autonomous knowledge bases (including knowledge base federation, secrecy-preserving query answering)
  • Theoretically sound yet practically useful approaches to functional and non-functional specification driven composition of complex services from components
  • Expressive languages  for representing, and model checking approaches to reasoning with, qualitative preferences
  • Algorithms for eliciting causal effects from disparate sources of observational and experimental data
  • Scalable algorithms and software for comparative analyses of large bio-molecular networks 
  • Machine learning approaches to analysis  and prediction of macromolecular interactions and interfaces

My ongoing research is focused on:

  • Computational abstractions of scientific artifacts (e.g., data, knowledge, hypotheses), and universes of scientific discourse (e.g., biology), and scientific processes (e.g., hypothesis generation, predictive modeling, experimentation, simulation, and hypothesis testing)
  • Computational infrastructure collaborative, interdisciplinary and transdisciplinary science
  • Design and analysis of algorithms for predictive modeling from very large, high dimensional, richly structured, multi-modal, longitudinal data
  • Elucidation of causal relationships from disparate experimental and observational studies
  • Design and analyses of accountable, explainable, and fair AI systems
  • Analysis and prediction of macromolecular interactions, elucidation of complex biological pathways e.g., those involved in immune response, development, and disease;
  • Predictive and causal modeling of individual and population health outcomes from behavioral, biomedical, clinical, environmental, socio-demographic data
  • Predictive and causal modeling of behavioral and cognitive systems in naturalistic settings
  • Modeling the structure, activity, and function of brain networks from fMRI and other types of data
  • Representing and reasoning with qualitative multi-stakeholder preferences
