John and Barbara Donovan
In 2005 John and Barbara decided to start Probe Software, Inc. with John as lead software developer and Barbara the company administrator. In addition, we work with software experts/consultants in graphics, network drivers and instrument physics to support our products.


A Bit of History...
John Donovan first became intrigued with EPMA using the ARL SEMQ electron microprobe at UC Berkeley in the 1980s where he was employed as a laboratory technician. After a graduate student imploded the vacuum chamber, he took the instrument completely apart and rebuilt it and has been hooked ever since. Finding the then available software for acquisition and reprocessing of data to be lacking, he embarked on a career long journey to write the best damn EPMA software available today.
He has been writing and evolving Probe for EPMA software since approximately 1990 and continues to make continuous improvements to the product at least once or even twice (or more) a week.
