An Accessible Visual Narrative for the Primary Energy Source of Life from the Fulldome Show Birth of Planet Earth
1st Place, SC'19 Visualization and Data Analytics Showcase

Paper (PDF)

Abstract:
Conversion of sunlight into chemical energy, namely photosynthesis, is the primary energy source of life on Earth. An explanatory visualization depicting this process is presented in the form of an excerpt from the fulldome show Birth of Planet Earth. This accessible visual narrative shows a lay audience, especially children, how the energy of sunlight is captured, converted, and stored through a chain of proteins to power living cells. The visualization is the result of a multi-year collaboration among biophysicists, visualization scientists, and artists, which, in turn, is based on a decade-long experimental-computational collaboration on structural and functional modeling that produced an atomic detail description of a bacterial bioenergetic organelle, the chromatophore. The energy conversion steps depicted feature an integration of function from electronic to cell levels, spanning nearly 12 orders of magnitude in time scales modeled with multi-scale computational approaches. This atomic detail description uniquely enables a modern retelling of one of humanity's earliest stories---the interplay between light and life.

Birth of Planet Earth fulldome excerpt: Photosynthesis in a chromatophore

"Photosynthesis in a Chromotaosphere," a sequence in the Spitz fulldome show Birth of Planet Earth, was selected to screen at SIGGRAPH's Electronic Theater, Monday, July 29, 2019. Hundreds of short films are submitted to this prestigious program each year, with only a handful selected for the event. It was also an official selection at Siggraph Asia, 2019, and was shown in the The SIGGRAPH Computer Animation Festival celebrates computer graphics as a medium for storytelling in animation, visual effects, games, and more. The event is recognized as a qualifying festival by the Academy of Motion Picture Arts and Sciences, and several works that were originally presented in this program have received Best Animated Short Academy Awards. Birth of Planet Earth is a joint production of Spitz Creative Media, NCSA's Advanced Visualization Lab, and Thomas Lucas Productions, Inc., in association with Tellus Science Museum.

Abstract:
This visualization of the quantum-mechanical process of photosynthesis involved combining structural models from atomic, protein, organelle, and cell scales. We descend into a prehistoric hot spring, revealing primitive bacteria which use an early form of photosynthesis to turn sunlight into chemical energy in structures called chromatophores. This fulldome animation follows the energy through progressively more stable forms: a captured photon, electronic excitation, pumped protons, and finally, synthesis of ATP molecules. The team used VMD, a GPU-accelerated molecular visualization tool, to create geometric abstractions from a 5-million-atom static snapshot of the scientific research model. To achieve an organic flight path through the 3D data, they adapted their Virtual Director camera choreography software to interface with VMD. In Houdini, they choreographed particle effects which were then exported to VMD for rendering of the hero chromatophore. Nine more layers were rendered in Houdini's Mantra, including 500,000 instanced chromatophores and particle effects, 300 high-resolution cell membranes, and depth passes to control luminance and depth effects. The visualization treatments from Houdini and VMD were combined in Nuke for a seamless flight through this dynamic microscopic light show.

Birth of Planet Earth, Fulldome Movie
Birth of Planet Earth tells the twisted tale of our planet's origins.

Scientists now believe that our galaxy is filled with solar systems, including up to a billion planets roughly the size of our own. The film employs advanced, data-driven, cinematic-quality visualizations to explore some of the greatest questions in science today: How did Earth become a living planet in the wake of our solar system's violent birth? What does its history tell us about our chances of finding other worlds that are truly Earth-like?

Chemical Visualization of Human Pathogens : The Retroviral Capsids,
Finalist, SC'15 Visualization and Data Analytics Showcase

Paper (PDF)

Abstract:
Retroviruses are pathogens characterized by their ability to incorporate viral DNA into a host cell's genome. Retroviruses like Rous Sarcoma Virus (RSV) infect cells during mitosis, when the chromatin is exposed to the cytoplasm. Conversely, the genus of lentiviruses, like the human immunodeficiency virus (HIV), have evolved to infect non-dividing cells. Despite infecting cells at different stages of their life cycles, RSV and HIV share a similar late stage replication cycle that is highly dependent on the group actin polyprotein precursor (Gag), which contains the matrix (MA), capsid (CA) and nucleocapsid (NC) proteins. Both HIV's CA and Gag are considered unexploited targets for pharmaceutical intervention. We describe the techniques that were used to build, simulate, analyze and visualize the structures of both Gag and CA, as well as we discuss scientific visualization needs that spurred development of an interactive GPU-accelerated ray tracing engine and the use of remote visualization technologies.

Visualization of Energy Conversion Processes in a Light Harvesting Organelle at Atomic Detail,
1st Place, SC'14 Visualization and Data Analytics Showcase

Paper (PDF)

Abstract:
The cellular process responsible for providing energy for most life on Earth, namely, photosynthetic light-harvesting, requires the cooperation of hundreds of proteins across an organelle, involving length and time scales spanning several orders of magnitude over quantum and classical regimes. Simulation and visualization of this fundamental energy conversion process pose many unique methodological and computational challenges. We present, in an accompanying movie, light-harvesting in the photosynthetic apparatus found in purple bacteria, the so-called chromatophore. The movie is the culmination of three decades of modeling efforts, featuring the collaboration of theoretical, experimental, and computational scientists. We describe the techniques that were used to build, simulate, analyze, and visualize the structures shown in the movie, and we highlight cases where scientific needs spurred the development of new parallel algorithms that efficiently harness GPU accelerators and petascale computers.

Consulting Activities:

I served as a consultant to Delcross Technologies LLC for the GPU and MPI-based parallel computing aspects of the projects:
  • "Graphics Processing Unit (GPU) Acceleration for Cosite Interference Prediction Tools", SBIR N131-008, funded by NAVAIR, U.S. Navy, 2013-2016.
  • "Antenna Placement Optimization on Large, Airborne, Naval Platforms", SBIR N101-022, funded by NAVAIR, U.S. Navy, 2010-2013.

I served as a consultant to Verachem LLC for the GPU parallel computing aspects of the project:
  • "Multilevel Parallelization of Software for Accurate Protein-Ligand Affinities", SBIR PAR-07-160, 1R44GM088867, funded by the National Institutes of Health, 2010-2014.

I served as a consultant to Production Data Services, developing tools for 3-D stereoscopic movie production. I developed and maintained a sophisticated software module for synchronized 3-D stereoscopic display of asynchronous, parallel-decoded video streams that formed the basis of the RushPlay 3D digital dailies system used in producing the Lionsgate 3-D movie My Bloody Valentine 3-D, released in January 2009.


Previous Employment:

I was previously a Senior Programmer/Analyst at Heuris/Pulitzer, and later Heuris Logic, developing commercial video encoding and transcoding software used in service bureaus, the standalone commercial MPEG Power Professional software, and plug-ins for the leading non-linear video editing systems. My work in this era was noteworthy mainly for my early use of parallel processing and SIMD instruction set extensions for acceleration of the routines for color space conversions, image filtering and de-noising, and motion estimation within the video encoder subsystem.
