He trained as a molecular geneticist with a focus on discovering and assessing the functional impacts of genomic polymorphisms and biomarkers on human disease. He has led several large genomics consortium studies for complex disease phenotypes. His group’s research interests focus on genome-wide association studies (GWAS), whole exome-sequencing, miRNA, mRNA, and proteomics/metabolomics of transplant donor and recipient’s genomes, with the aim of using genomic and other biomarkers for the diagnoses and prognoses of post-transplant compilations. He is a PI on a number of NIH funded studies including an NIAID U01 study ‘MHC & KIR Sequencing and Association Analyses in the iGeneTRAiN Studies’; an NIAID R01 study “Multiomic Biomarker Discovery and Validation in Heart Transplant Patient Populations” and an NICHD funded 12-site prospective biomarker master reliance study in pediatric kidney transplantation where 450 patients are tested for diagnostic and prognostic markers that underpin acute rejection and post-transplant infection (NCT03719339) using urine-DNA and other bio-specimens. He has led or co-authored over 145 genomic publications and has given over 100 presentations in 25 countries including numerous national and international conferences.
