Mary Ann Maher is the CEO of SoftMEMS LLC. She received her Ph.D. degree in 1989 from Caltech in the area of semiconductor device modeling. She subsequently conducted post-doctoral studies at the Swiss Center for Electronics and Microtechnology (CSEM) in Neuchatel, Switzerland and joined Tanner Research in 1992 becoming the software architect for their IC design tools. She moved to MEMSCAP in 1999 as an Executive Vice President and became the company CTO in 2001. She founded SoftMEMS LLC in 2004 to address the need for co-design tools for systems incorporating MEMS sensors, electronics and packaging.
