Research Page for Bhautik Joshi


I have a strong academic background background in computer science, and have applied this to a broad set of research interests. These include: computer graphics and image processing, real-time interaction in complex environments, volumetric mesh generation, and parallel processing of large datasets.

Recently, I have completed a PhD with the CSIRO BioMedIA Lab titled Model Generation and Interaction in Surgical Simulation, where I investigated real-time algorithms for discretising and simulating tissue based on medical imaging data and realistic biomechanical models.

Currently based in Sydney, Australia, I am working as a consutant to add real-time complex physics to existing gaming platforms. In the future I hope to continue further work in the entertainment, film and TV industries, bringing expertise in adding efficient, computationally cheap physical simulations to existing systems.

Skills

Academic History

2002-2006: Undertook a PhD, titled "Model Generation and Interaction in Surgical Simulation" jointly supported by the BioMedIA Lab at the ICT Centre, CSIRO, and the Graduate School of Biomedical Engineering at UNSW. Research focused on the automatic generation of tetrahedral meshes from segmented anatomical voxel datasets and realistic physical interaction with these in real- on near real-time. Thesis is submitted and under review.
2001: Undertook my Masters thesis at the Dept. Nuclear Medicine & Ultrasound at Westmead Hospital, Sydney, Australia
2000: Undertook my Honours thesis with the Medical Imaging group at Telecommunications & Industrial Physics, CSIRO, Sydney, Australia
1997-2001: Completed BE(Computer Engineering)/ME(Biomedical Engineering) at the Graduate School of Biomedical Engineering at the University of New South Wales

Papercraft

During the course of my PhD work I investigated the distortion-free unfolding of model geometry into a 2D net for good quality texturing. I applied some of these techniques to models from early 3D computer games, and made these unfolded nets available for free online. These generated a considerable amount of interest, leading to two magazine articles (in Jumpbutton and Computer Gaming World - see left) and a TV appearance (on ABC2's Good Game - see right). Links to the articles can be found here and here; a link to the TV segment can be found here.

Ultrasonics History

Early on in my PhD career, I started an initiative to record and document the development and history of Ultrasound technology in Australia. The materials and equipment collated are now stored and displayed by the Powerhouse museum in Sydney, Australia.

Open-source DICOM writer for IDL

I developed an open-source library for the writing of DICOM images in IDL. It has enjoyed wide use, and part or all of the library has been included in a number of third-party packages (link, link, link, and link).
