Research statement

I am currently doing research in two areas, each including collaboration with other institutes and institutions.

Interstellar communication

Drawing upon my background in earthbound digital communications, I have been studying the possibilities for expanding the types of signals that are sought from narrowband carrier-like and broadband pulse-like signals to broadband spread-spectrum signals such as are widely used in terrestrial wireless communication. I am studying the design of a digital communication system through space at distances of 10 to 100 light years and at microwave radio frequencies. The relevant channel and propagation parameters are drawn from astronomy and astrophysics, including prominently noise, Doppler shift due to motion of transmitter and receiver, and low-density plasma occupying interstellar space. The immediate application is to infer likely characteristics of radio signals that present evidence of technology elsewhere in the Universe using existing radio telescopes. Future applications include the design of information-bearing signals that we might transmit in the direction of known planets in nearby solar systems (hoping they would be received), and communication with spacecraft at great distances. I have several collaborators on this research at the SETI Institute in Mountain View, the Hat Creek Radio Observatory of the University of California, and the Australian Center for Astrobiology in Sydney. I am hoping to influence the types of signals that are included in the SETI searches by Observatory's Allen Telescope Array (ATA) and Berkeley's SETI@home project.

Software business

Starting in 1996, I developed two courses in the new School of Information Management and Systems (now called the School of Information), one on “networked applications” and the other on “strategic technology”. These followed my interest in the overlap between economics and business with technology, particularly with a view toward making our technologies more successful by taking account of market forces. Each course led to a book, “Understanding Networked Applications” and “Software Ecosystem” respectively. This led to my recent paper on “Rethinking Components”, with ongoing work on industry roadmapping, end-user innovation, and enhanced industry collaboration. I have specifically been focusing on the software industry because it is undergoing particularly strong change right now and because I encountered and became interested in software business management issues in my own entrepreneurial activities.

 

I recently collaborated with the Software Business Laboratory at the Aalto University of Science and Technology in Finland (formerly Helsinki University of Technology) because their interests are well aligned with my own.  Our project there,  “Software Business Foundations”, was supported by the Finnish research agency Tekes, and the emphasis is on understanding those factors that make software businesses different from other businesses, as well as providing strategic guidance to software entrepreneurs in these areas.  One major initiative of the project is the Software Business Community, an online community of researchers, managers, practitioners, and end-users who are working to understand and share their expertise and experience about software business.
