Michael has contributed to five US patents and is a member of the Association of Computing Machinery and the Institute of Electrical and Electronics Engineers.

Personal projects related to computing include documenting the quirks of the IBM PCjr and bringing modern networking to DOS machines through mTCP, an open source TCP/IP stack and applications for early IBM compatible personal computers. Michael is also the organizer and producer of the VCF Pacific Northwest events, the first of which was held in 2018.
