Dr. Tiwari completed his Master’s Degree (M.Sc.) in Physics, with Biomedical Physics as a special elective, from the Central Department of Physics, Tribhuvan University of Nepal. After completing his M.Sc., Dr. Tiwari taught Physics courses, including engineering Physics and Biomedical Physics, at different campuses of Tribhuvan University. 

  Dr. Tiwari obtained his PhD degree from Florida International University (FIU), Miami, FL, USA. During his PhD tenure, Dr. Tiwari conducted scientific research in Biophysics, primarily focused on investigating biomolecular interactions at the nanoscale and using surface plasmon resonance (SPR) technology to study these interactions . 

  Currently, Dr. Tiwari is a faculty member in the Department of Oncology, School of Medicine at Georgetown University. Dr. Tiwari's current research includes investigating protein-protein and protein-DNA interactions as well as the interaction of small molecules with proteins and DNA for drug discovery. Dr. Tiwari's research utilizes both computational and experimental techniques, including molecular docking, molecular dynamics (MD) simulations, virtual screening, and SPR.
