My research interests are Artificial Intelligence for Science, Explainable and trustworthy AI, Digital Twins, Performance evaluation for classical and quantum computing, and Visualization. Previously I also worked on Virtual Reality, X-ray Imaging and High performance computing for medical and scientific domains.
My current funding resources are DOE's BER and SciDAC programs as well as BNL's internal projects (e.g., LDRD and NSLSII's DSSI division).
