A passionate philanthropist, Ken is committed to strengthening humanity’s future by supporting initiatives that advance breakthroughs in science and medicine, and expand access and opportunity in education. His catalytic giving empowers students across our country to succeed and enables people to live longer and healthier lives.

Most recently, during the COVID-19 crisis, Ken took immediate action and mobilized partners across government, business, and healthcare to fund critical research. He played a key role in helping to safely return hundreds of Americans from Wuhan, China. Additionally, Ken’s thought leadership was instrumental in architecting Operation Warp Speed’s accelerated vaccine development strategies, which ultimately saved hundreds of thousands of lives.

As the pandemic engulfed America and schools were closing their doors, Ken enabled students to continue their learning by playing a leadership role in providing free high-speed broadband access to 400,000 low-income homes across Chicago and Miami. Championing his belief that a high-quality education is the on-ramp to the American Dream, Ken has funded transformative undergraduate scholarships to equip thousands of low-income and first-generation students with the skills and tools needed to succeed.
