A Brief Company History

H. Bruce Rinker, Ph.D., the founder and sole proprietor of Bioquest Solutions LLC, holds ownership of the trademarked name, “Bioquest Expeditions,” as an agreement with previous business partners from a now-defunct company called International Student Research, Inc. The company, based in McLean, Virginia, operated for 5 years in the late 1980s and early 1990s to link students of all ages with scientific organizations around the world in a three-phase experience: preparation, immersion, and follow-up advocacy. Dr. Rinker created the trademarked name, which was returned to him upon the dissolution of International Student Research, Inc.

Dr. Rinker founded Bioquest Solutions LLC in spring 2016. He combined the terms, Bioquest and Solutions, to indicate the sustainable focus of the company and then solicited the help of Nadine Zeevaert Lamas, an internationally recognized graphics designer based in México City, for the company logo. The stylized glyph captures the concepts of land and water, wild and urban, human and nonhuman in its colors and abstract shapes.

Bioquest Solutions LLC provides its science-based services to tackle local, regional, and international concerns about the environment with the firm belief that the planet and human communities can live compatibly and sustainably.

In addition to the work of company principal Dr. H. Bruce Rinker, the mission of Bioquest Solutions is further served by its Scientific and Technical Advisory Council (STAC).

Basic Definitions

What is sustainability?


From an ecological perspective, sustainability is the theory and practice of using Earth’s limited natural resources to meet the present and future needs of Society. It is the capacity to create, endure, and integrate. Sustainability infers the idea that social, economic, political, and environmental progress is attainable within those limits. Thus, the term implies a healthy partnership between Earth and humanity. It implies humanity’s guardianship of the planet in our perceptions, celebrations, and respect. It also implies humanity’s ancient vocation to care within the context of an elder and evolving Earth.


What is sustainable development?

Sustainability is often associated with development as in the term, sustainable development. Sustainable development is the organizing principle for sustainability. The classic definition of sustainable development is “development that meets the needs of the present without compromising the ability of future generations to meet their own needs.” [1] Sustainable development has also been defined as “something that improves the quality of human life while living within the carrying capacity of supporting ecosystems.” [2] In our employment of Earth’s resources, we strive toward responsible stewardship while we consume, develop, and nurture the world around us.


What is stewardship?

Far from being a frivolous or faddish term, sustainability equates on many levels with responsible stewardship. Stewardship is a covenantal partnership between people and planet that honors diversity and favors productivity. Old-growth forests, coastal wetlands, and barrier reefs are examples of generative biological sustainability that necessitate humanity’s stewardship because these are deep-time reservoirs or incubators of biodiversity. So, too, we have ancient systems of human diversity across the planet called geo-cultural domains – from Amazonia to the Andes, from the Mediterranean Basin to the Tibetan plateau, from the Horn of Africa to the Nile Delta, from the Western Ghats to Wallacea, from the Caribbean to Mesoamerica – that require our diligent stewardship. The wild roots of cultures and the importance of our ecological heritage are parts of our humanness, both deserving our perpetual diligence as stewards of creation.


What’s the bottom line?

Sustainability. Sustainable development. Stewardship. Three interwoven aspects of an ever-unfolding partnership for Earth and Society. Bioquest Solutions LLC embraces these three components for its work at home and abroad.
