Pamela Conrad is an internationally recognized landscape architect and climate advocate. She is a senior fellow with Architecture 2030, and a 2023 Loeb Fellow and Faculty Lecturer at the Harvard Graduate School of Design. She founded Climate Positive Design to enable climate action by providing guidance and an app to support design teams in drawing down carbon while creating environmental, social, cultural, and economic co-benefits. She is a farm girl from Missouri, inspired by the richness and ingenuity of nature.

Stephanie Carlisle is an architect and ecologist whose work focuses on the interaction between the constructed and natural environment, including life cycle assessment (LCA), urban ecology, environmental justice, and climate policy. She is a research scientist at the Carbon Leadership Forum, where she works to develop open-access embodied carbon and LCA data, tools, and methods to support the building sector in radically decarbonizing construction.  Stephanie joined the faculty at the University of Pennsylvania Stuart Weitzman School of Design in 2014. Previously, Stephanie worked for nine years as a Principal and Environmental Researcher at KieranTimberlake Architects in Philadelphia, where she helped lead the office’s research on embodied carbon, material health, landscape ecology, and environmental impacts. Since 2012, she worked on the development team for Tally, a software tool that enables architects and engineers to conduct full-building life cycle assessments during design. 

Marieke’s leadership in multidisciplinary practice and landscape architecture has yielded significant, sustained impacts at local and national scales. Her commitment to promoting sustainability and ecological principles in dense environments has helped to create inherently social spaces that spark belonging and identity. She believes in the power of collaboration, emphasizing co-creation and design equity to ensure that built work reflects the unique character, values, and needs of a community. Marieke is an enthusiastic supporter of Climate Action and carbon drawdown in her work. She has served for three years on the ASLA Climate Action Committee, as well as for ten years at the chapter level. Additionally, she volunteers her time to support homeless and affordable housing, arts, and environmental non-profits.

Mariana Ricker is passionate about California landscapes and emphasizes the importance of site-specific, sustainable landscape design. She enjoys working in urban settings that engage diverse user groups and activate spaces essential to civic life.

In her work as a landscape architect, Mariana seeks to create memorable experiences, connect people to the environment, and provide elegant solutions to accomplish the project vision. At SWA, she works on a wide range of projects, from community parks to large-scale urban development and planning around the Bay Area and beyond. Mariana is committed to climate action within her project work and professionally. She is a member of the national ULI Sustainable Development Product Council, and currently sits on both national and local ASLA Biodiversity & Climate Action Committees. 

Andrew Wickham is a Project Leader at LPA, a national integrated design firm.  Andrew leads designs at the intersection of built, cultural, and natural systems and is a champion of metric-driven design.  His interest lies in how the blending of built and natural environments can enhance a user’s experience and reinforce values of equity, ecology, and curiosity.  Andrew is a proven thinker and strategist, speaking at numerous conferences about the value of performative landscapes and human experience. He is currently Trustee for California Sierra Chapter of ASLA and co-chair of the Leadership and Communication sub-committee of the national Biodiversity and Climate Action Committee.

Meg Calkins, FASLA, SITES AP, is a Professor of Landscape Architecture and Environmental Planning at North Carolina State University. Meg’s scholarship focuses on the environmental and human health impacts of site construction details and materials. She is the author of the book "Materials for Sustainable Sites" and editor of the "Sustainable Sites Handbook". She is currently writing a book with the working title of "Details and Material for Resilient Sites: A Carbon Positive Approach" (Routledge 2025). Meg has taken an active leadership role in development and implementation of the Sustainable Sites Initiative (SITES) since 2003.

Satyam is an associate on the Embodied Carbon Initiative within the Carbon Free Buildings team. His primary focus is on reducing the carbon impact of building materials by advocating for the broad adoption of low-embodied-carbon and carbon-sequestering building materials.

Satyam previously worked as a structural engineer and construction manager in his home country of Trinidad and Tobago. He planned, designed, and managed the construction of facilities in the education, healthcare, and housing sectors, to name a few. He focused on ensuring projects were on a sustainable pathway by reducing embodied carbon content, introducing green concrete solutions, and advocating for renewable energy and efficient wastewater management systems. He led cross-functional teams and fostered engaging communication efforts between stakeholders and contractors to ensure projects were finalized within expected timeframes and budgets, and to end-user satisfaction.

Bryce Carnehl has been in the landscape industry for over 20 years working in construction, landscape architecture, sales, corporate social responsibility, and marketing. Throughout these years he has dedicated himself to promoting the value of green spaces.

Every project begins with a plan, and better planning leads to project success. Bryce now works to create business opportunity for landscape stakeholders through design, planning, and specification efforts. He believes that together we can build business prosperity, increase the value of landscapes, and ensure healthy communities in which we all live, work, and play.
