Gerard Sleefe, PhD

Gerard Sleefe is Senior Advisor at The Chertoff Group, a global advisory firm founded by former secretary of Homeland Security Michael Chertoff that specializes in security and risk management. Sleefe earned his undergraduate degree from Hofstra University before completing his Ph.D. in acoustics engineering at MIT in 1982. His doctoral research examined acoustic backscatter from random media, developing signal models and parameter estimation techniques applied to ultrasonic tissue characterization—work at the intersection of physical acoustics and medical imaging. He subsequently built a career applying signal processing and acoustics expertise to national security and defense contexts, before joining The Chertoff Group to advise clients on security strategy.
