christopher grayce
I do consulting and contract work in the area of scientific, bioinformatic, and scientific instructional computing. I have an expert knowledge of molecular chemistry and physics, statistical modeling and inference, and in the design and use of complex numerical algorithms. I also have considerable experience in the development of scientific software packages -- monolithic or modular, standalone or client/server, threaded or not.  [methane molecule]

internet weather
Internet weather is the ease with which data can be transferred from one computer to another across the Internet. ``Sunny'' weather is when a computer can send and receive data quickly and without loss. ``Stormy'' weather is when it can't. It's particularly interesting to measure Internet weather if you have a shared broadband connection (like a cable modem or shared T1), and you are curious about what your actual available bandwidth might be.

I've developed a package of very small footprint, speedy C code for use on Linux systems which measures Internet weather and reports it conveniently on a set of Web pages.

The latest source code, yours for the downloading: wx-0.93.tar.gz

The latest installation notes: wx-0.93-README.txt

java computer simulation
Computer simulation is great for studying and presenting complex systems. I've developed a set of Java classes that make it easy to implement and visualize simulations of molecular systems. You can download the classes and documentation for free.

Getcher red-hot classes right here: simulate-0.93

educational applets
Java applet simulations can give the student of physics and chemistry a chance to explore scientific principles the same way the research scientist does: by messing around with a (simulated!) system that exhibits the principles.

So educate me, then.

bioinformatics
Bioinformatics is the developing field of mining copious quantities of biochemical data to extract interesting statistical inferences. The techniques of statistical mechanics are invaluable.

Let's see!

machine vision
Rapid and robust automated image analysis of photographs made of cell cultures under a microscope can greatly assist the discovery of key compounds in high-throughput chemical screening. We've developed a suite of image analysis tools for use at Harvard's ICCB.
