Teresa Nelson, PhD, Astia Academic in Residence, 2015;
Member, National Women’s Business Council Professor and Director of the Entrepreneurship Program

Dr. Teresa Nelson holds the Elizabeth J. McCandless Professor of Entrepreneurship Chair at the Simmons School of Management. She is also the Director of the School of Management’s Entrepreneurship Program. Her teaching, research, and consulting focus on issues of entrepreneurship and global business, most particularly around start-up and growth company governance and top management team dynamics. She has been engaged for more than a decade with global business issues, especially in China and the European Union.

In the classroom, Dr. Nelson engages executive and graduate students in rigorous conceptual and experiential learning, believing that adults will benefit from educational encounters that move them out into the world of practice taking into account their talents, goals and the emerging business world of today. Nelson has taught on five continents and travels extensively. She has led travel courses for executives and students to many parts of the world, including China, where she has experienced first-hand the emergence of the market economy over the last dozen years. At Simmons she teaches entrepreneurship and strategic management in the MBA program.

Nelson’s primary research is related to the implications and outcomes of firms transitioning through growth stages up to and through initial public equity offering. She has studied product, process and performance changes as well as the implications of firm growth patterns on women as entrepreneurs of new ventures and within the corporation. Her experience in global business has translated into research on the markets of China and the strategic implications of the organization of global stock exchanges. As an affiliate of the Center for Gender in Organizations, Nelson is now engaged in multiple research projects to build knowledge around women and entrepreneurship, particularly high growth entrepreneurship.

Dr. Nelson had more than 10 years of experience in business consulting, government, and politics before returning to school for her MBA and Ph.D. She has founded two businesses and works as an affiliate consultant with two others. She is a frequent and noted speaker on issues such as “The Art of the Pitch”, “China Today” and “Entrepreneurship and Women”.

“We started Astia to address the issue of women’s access to capital, specifically venture capital, by women entrepreneurs building technology companies.
