Introduction
Devashish Shrivastava currently works at the Division of Surgical Devices, FDA Laboratories. Devashish does research in developing validated computational tools to predict tissue heating and associated tissue effects such as damage due to internal and/or external, local and/or systemic head loads in medicine, surgery, and during occupational and recreational activities.

The dielectric properties of biological tissues are key parameters that support the design and usability of a wide range of electromagnetic-based medical applications, including for diagnostics and therapeutics, and allow the determination of safety and health effects due to exposure to electromagnetic fields. While an extensive body of literature...
A computational assessment of in vivo thermal due to laser irradiation damage is presented as a function of the laser applicator length, total effective absorption coefficient, and heating duration for the peak tissue temperature of 100 °C. Spatio-temporal tissue heating is computed by solving the Generic Bioheat Transfer Model (GBHTM), a first pri...
Counter-current (vessel-vessel) heat transfer has been postulated as one of the most important heat transfer mechanisms in living systems. Surprisingly, however the accurate quantification of the vessel-vessel, and vessel-tissue, heat transfer rates has never been performed in the most general and important case of a finite, unheated/heated tissue...
This work presents the first numerical validation/sensitivity study of a new bio-heat equation, the tissue convective energy balance equation (TCEBE) in an unheated tissue with a simple but physiologically realistic 3D arterial blood vessel network. The validation of the TCEBE is performed by comparing its predictions of the tissue temperature fiel...
