Probably need to put a suited-up picture here.
I am a Cosmology Data Science Fellow at Berkeley Center for Cosmological Physics.
I am also affliated with Berkeley Institute for Data Science.
I write a lot of programs that produce and sweep through a lot of data; I mainly use ViM to
do the programming. Those are worthwhile and allowed to be hosted on the internet, can be found at
my github page. In earlier days I was involved with GNOME2 with a side-line project gnome-globalmenu.
I play guitars and do guitar set-ups for friends; for this purpose I mainly use allen wrenches
and philips screwdrivers: ViM doesn't help much on this issue.
My professional work spans three fields:
- extreme-scale super-computing applications, and
- tools for scientific data science.
Please refer to my CV; or
the list of publications.
I was part of several largest cosmological simulations.
These simulations required some of the largest super-computers today(or then), running at their full capability
for days; that's hundreds of millions of CPU-hours.
We do make important predictions about blackholes and galaxies with these simulations!
Here is a list of research topics and projects that I have contributed to:
- Large Scale Structure and cosmology, perturbation theory;
- Formation of galaxies, galaxy clusters, star-formation models
and super-massive blackholes.
- Weak lensing and intrinsic alignments.
- Reduction of imaging data from imaging surveys.
- Super-computing Applications
- Solver for cosmological hydrodynamics;
- Parallel Fast Fourier Transformation;
- Massively parallel sorting;
- Python on super-computers;
- Scientific Data Analysis
- Parallel data analysis of N-body simulations
- In-node Map-Reduce via Multi-processing
- Hierarchical Data Format for large data sets
- KD-tree and pair-wise counting
- Visualization of smoothed particle field
