Ayush Dubey

Ayush Dubey

Ayush Dubey is a Yale School of Management MBA candidate, London Business School exchange student, and emerging speaker at the intersection of AI, technology M&A, private equity value creation, energy transition, and enterprise transformation.

His work focuses on how organizations make better decisions when technology, capital, infrastructure, and human judgment are all changing at once. In private equity advisory, Ayush has worked across technology diligence, carve-out planning, post-merger integration, and value creation strategy. His broader operating experience spans digital transformation, manufacturing technology, AI/ML deployment, energy analytics, sustainability strategy, and global operations.

Ayush’s energy and infrastructure lens is central to his work. At Yale, his academic and project work has covered climate finance, project finance, energy and infrastructure, land use, real assets, sustainable finance, renewable energy, and geothermal commercialization. His capstone work includes geothermal data-center cooling strategy and commercialization for a climate-tech company, as well as forest and carbon decision-support work for land-use protection. At London Business School, his private equity-focused exchange adds exposure to corporate turnarounds, pricing, and strategic innovation, strengthening his ability to connect investment logic with operational execution.

Ayush’s AI thought leadership examines a central question: what happens when AI makes individuals and organizations appear more capable before their judgment, governance, and operating systems have caught up? His CIO.com article, “The 10-Man Parity Rule: When AI Adoption Accelerates Faster Than Organizations Can See,” argues that AI is increasingly pulled into work by employees, quietly outpacing traditional governance and reshaping who gets leverage inside companies.

In 2026, Ayush was selected to speak and present at AI @ Yale Symposium: From Innovation to Impact. His talk, “Clarity before Understanding: How Generative AI Reshapes Judgment in MBA Education,” explored how AI can produce polished synthesis before independent judgment is formed. His connected poster, “The AI Visibility Gap: Why Leaders Misread Capability Inside Their Own Organizations,” translated the same concern into the workplace context, asking how leaders can assess capability when AI changes the visible signals of work.

Ayush also serves as a reviewer for the Academy of Management Annual Meeting in M&A and is listed on the UNESCO Expert Roster in Natural Sciences. He holds a B.Tech. in Aerospace Engineering from IIT Bombay, bringing a systems-level lens to questions of AI adoption, energy transition, corporate transformation, private equity value creation, and leadership judgment.

Dr. James C. Rodríguez, MSW

Dr. James C. Rodríguez, MSW, CADC
President & Chief Executive Officer, Fathers & Families Coalition of America
Author | Founder, Borinqueño Within Press | Certified Executive Coach | Clinical Social Worker | Veteran | Researcher | Policy Architect | Curriculum Developer | International Trainer

"I am a Boricua. A dad. A soldier. A professional social worker. An advocate. A teacher. A professor. A counselor. And a friend. And with every role, I lead with love and serve with purpose."

Biography
Dr. James C. Rodríguez, MSW, CADC, is a globally celebrated architect of fatherhood engagement, social policy reform, and transformative leadership development. For over four decades, he has shaped public health, child welfare, mental health, and professional education—building bridges across disciplines, communities, and continents. His career is defined by multidimensional leadership and a relentless pursuit of equity, healing, and opportunity for all. A proud father, soldier, social worker, and visionary educator, he has devoted his life to helping people rediscover hope, dignity, and purpose. His reach spans early childhood education, public health, leadership development, and fatherhood advocacy—fields that, in his hands, become pathways toward healing and intergenerational equity.

"Insights give way to dreams—developing vision—creating purpose that ends in your why."

Foundations: Service, Resilience, and Cultural Identity
Born into a low-income household and shaped by the adversity of the child welfare system, James began his journey at age 17 as a U.S. Army Combat Medic. By 22, he became one of the youngest Substance Abuse Counselors in the Department of Defense, retiring with honors and meritorious distinction in the reserves. Over more than two decades of military service, he developed expertise in trauma response, behavioral health, and law enforcement. This experience forged his devotion to discipline, compassion, and advocacy for the vulnerable.

James's service has been recognized at the highest levels: he is the recipient of the Presidential Lifetime Call to Service Award (President Barack Obama), Points of Light Award (President George H. W. Bush), Meritorious Service Medal (U.S. Department of Defense), and Congressional Certificates from Maxine Waters, Sheila Jackson-Lee, Barbara Lee, and Diane E. Watson. He is deeply honored by the Ceremonial Elder Proclamation from the Qutekcak Native Tribe of Alaska, the National Social Worker Leadership Resolution (FFCA), and hundreds of additional accolades from national, state, tribal, and community organizations.

Architect of Systems Change: Building Movements, Securing Hope
As founder and CEO of the Fathers & Families Coalition of America (FFCA), Dr. Rodríguez transformed a grassroots Arizona network into an international force with offices in California and Puerto Rico, and active partnerships across North America, the Caribbean, Africa, Europe, and Australia. He was instrumental in creating one of the nation's first TANF-funded fatherhood programs, a model that generated over $75 million in resources and has been replicated nationwide. Under his leadership, FFCA's International Families & Fathers Conference—now in its 27th year—has become a global destination for educators, policymakers, and innovators, advancing justice and family well-being.

A founding steering committee member of the Fatherhood Research & Practice Network (FRPN) at Temple University, James has shaped federal research and policy, serving as principal investigator and senior research consultant on projects for the Office of Refugee Resettlement, CDC, NIMH, and the Oregon Center for Applied Science. His work has driven advances in public health, trauma-informed care, and family resilience.

Signature Curriculum Development and Thought Leadership
James is a master architect of transformational curricula and professional development, including the Advanced Practitioner Credential™ Course (NASW Arizona-approved), OAR Leadership Institute™ (Ownership • Accountability • Responsibility), FFCA DiSC Model™, Ikigai & The Power of Kintsugi™, and SAMHSA-approved Fatherhood and Mental Health Curriculum. He also developed the Strengthening Families Through Nurturing Leadership model. His trainings are lauded for blending cognitive science, neuroplasticity, emotional intelligence, trauma-informed care, and actionable leadership strategies, and have reached over 30,000 professionals—social workers, educators, clinicians, nonprofit leaders, and public officials—across the U.S. and four continents. Over 85% of program graduates report improved outcomes, including higher client engagement and service completion.

Certified as an Executive Coach, Master Trainer for The John R. Wooden Course™, Certified DiSC® Trainer, Life Coach, Ikigai Coach, and Schema Therapy Practitioner, Dr. Rodríguez's leadership development institutes have set new standards for excellence in behavioral health and family services.

He serves on the editorial board of PHYLON: The Clark Atlanta University Review of Race and Culture, which he joined upon the appointment of Dr. Obie Clayton, Jr., and supports scholarship on race, family, and social change.

Policy Leadership, Board Service, and Community Engagement
Dr. Rodríguez's policy influence extends to every level of government. He has developed legislation for Connecticut's Fatherhood Initiative, served on Arizona and California TANF/family-strengthening task forces, and advised the New York City Mayor's Fatherhood Advisory Council, DYCD, and ACS. He has shaped policy in partnership with SAMHSA, Region II Head Start, the State of Maryland, and the National Federation of Families for Children's Mental Health. He has provided expert testimony before the U.S. House Ways & Means Committee. He collaborates with Congressman Danny K.

His work with the Somali Association of Arizona, the Hispanic/Latino and African American Parent Depression Research Project, and tribal partners has been recognized for its transformative impact on systems and inclusion.

Author, Storyteller, and Purpose-Driven Advocate
As founder of Borinqueño Within Press and author of the forthcoming The Purpose Within—Rise Out of the Ashes Like the Phoenix, Dr. Rodríguez's story is a testament to resilience, hope, and the enduring power of purpose. He weaves together memoir, leadership philosophy, and spiritual reflection, inspiring audiences to discover their own capacity to lead and transform.
