Associate, GIS Manager and Analyst
Mark Lightner, GISP, CFM
Mr. Lightner is a Geographic Information System (GIS) Analyst with over a decade of experience bringing innovation and automation to climate change and flood mapping projects. He has used his technical expertise to develop the “one map equals many futures” sea level rise and storm surge inundation mapping available on the Adapting to Rising Tides Shoreline Flood Explorer, and is currently expanding on this work to look at the impacts of sea level rise on the shallow groundwater layer. Mr. Lightner is experienced in python scripting and automation techniques, web-based database management, and developing web-based geospatial applications and tools that can support stakeholder engagement and decision-making processes.
Associate, Marine Geographer and GIS Analyst
Abby Mohan, MSc
Abby Mohan is a marine geographer and GIS analyst who works on the intersections between coastal use, coastal policy, coastal science, and best practices in communicating these complex issues to the public. Abby is active in the maritime community and serves as the Vice Chair of the Greater Farallones National Marine Sanctuary Advisory Council (GFNMS). Abby also supports climate change vulnerability and risk assessments with a focus on sea level rise and emergent groundwater. Abby has worked with the GEF Blue Forests project translating the experiences of project managers from carbon and ecosystem service based mangrove conservation and restoration in seven countries (Abu Dhabi, Dominican Republic, Ecuador, Indonesia, Kenya, Madagascar, and Mozambique) to develop lessons learned, tools and guidance to replicate and scale up successes from these pilot projects. Abby is also a licensed captain and enjoys being out on the water every chance she can get.
Associate, Resilience and Flood Risk Management
Maryellen Hearn, MSc
Maryellen is a resilience and floodplain management specialist, with a primary focus on flood risk assessments and climate adaptation. She has been supporting the Port of San Francisco’s Waterfront Resilience Program since 2018, providing the critical intersection point between the multi-disciplinary team focused on seismic and flood hazards as well as long-term resilience. Maryellen’s background also extends to multi-disciplinary projects with an environmental focus, bringing together aspects of socio-economic science, social equity, sustainability, and resilience in planning for flood and disaster risk reduction. She uses GIS software to collect, organize, analyze, and present geospatial data for local and international projects. Maryellen is also active on the volunteer front and served two years as the Representative for Disaster Risk Reduction on the Advisory Board for the international nonprofit Water Youth Network.
James Neher, PhD Candidate
James is a PhD candidate (on leave) at the University of California Berkeley, and an Engineering in Training (EIT) with a background Civil and Environmental Engineering, including environmental fluid mechanics and numerical modeling. He is experienced in data analysis, visualization, and predictive modeling, and proficient in multiple coding languages including. Through his academic experience he has , developed strong collaboration skills and he enjoys communicating about his research to technical and lay person audiences. His PhD research focused on meso- to micro-scale coupled simulations of flow over complex terrain, and he is bringing these skills to our current collaboration with the Lawrence Berkeley National Laboratory looking at how atmospheric rivers and extra tropical storms throughout the Bay Area will change with a warming climate.
Daisy Ramirez Lopez
Daisy is a recent graduate of the University of California, Merced with a bachelor's degree in Environmental Engineering. She has a solid background in research and report development, along with a personal passion for improving both our natural and built environments. Daisy is supporting the "Shallow Groundwater Response to Sea Level Rise" project funded by the California Resilience Challenge. Her educational background and previous internships have helped her develop strong technical and communication skills that will be an asset across multiple projects.
