The lab's mission is to conduct rigorous scientific inquiry into forest ecosystems. The lab endeavors to advance fundamental and applied understanding of forest dynamics—from individual trees to landscapes—by quantifying how climate, disturbance, and management shape forest structure, function, and resilience. The lab strives to produce reproducible, transparent science and open data and tools that inform land conservation and restoration goals and sustainable land stewardship.

The purpose of the lab is to develop lab members into well-rounded, critical thinkers with technical skills that advance understanding of how forests change over time, enabling society to steward ecosystems more effectively by supporting biodiversity conservation, land-use goals, and community well-being. The lab is dedicated to preparing lab members to become scientists and practitioners who can lead collaborative, ethical, and reproducible research programs that translate ecological knowledge into on-the-ground outcomes.

Badri Bhattari

Picture

PhD student

Badri Bhattarai has a strong background in sustainable forest management, forest carbon dynamics, and biodiversity conservation. He holds a master’s degree in forestry from Tribhuvan University, Nepal, where his research focused on treeline dynamics and their impact on carbon storage in the Nepal Himalayas.

Badri’s research focuses on forest disturbances and ecosystem resilience, specifically understanding how forest productivity, biomass, stand diversity, and climatic interactions influence resilience to bark beetle disturbances.
He has worked on several national and international projects in Nepal, including the Global Mountain Biodiversity Assessment (GMBA) in collaboration with the International Centre for Integrated Mountain Development (ICIMOD) and the University of Bern, National Forest Inventory; development of allometric equations of major tree species of Nepal; remeasurement of permanent sample plots; identification and mapping of urban springsheds; preparation of sustainable forest management plans for community forests; and environmental impact assessments of hydropower projects. His duties as a professional varied from field-based data collecting and spatial analysis to report preparation and managing projects.
​

In his free time, he enjoys learning new skills, travelling to new places, hiking, connecting and networking with people and exploring new ideas and perspectives.

Sarah Morais

Master's Student

Sarah is a Forest Engineer from the University of Brasília (UnB), Brazil, and Managing Partner at Ecoquality Soluções Ambientais. She has over 10 years of experience leading ecological restoration projects in the Caatinga biome, with a focus on degraded land recovery associated with renewable energy development.

Her current interests focus on investigating the factors that promote forest resilience, understanding forest recovery dynamics following disturbance, and evaluating ecosystem recovery through biodiversity patterns, ecosystem function, and soil–plant–water interactions.

In her free time, she enjoys reading, traveling, and spending time outdoors with her family.

​Non-Thesis Master's Degree Students

​Julieta Viñas Vilá 

Picture
Julia is a master's student with a BS in Horticulture. She has always had a passion for conservation and restoring the environment and will carry that into her gradutue study.  She is a firm believer in working alongside nature and not against it. She hopes to expand her knowledge and skills to eventually have a career to assess tropical and coastal ecosystems sustainably. 

Emile Belmontes​

Emile is from Houston, Texas, he has a Bachelor of Arts in History from Saint Edwards University. He is passionate about land management in forest restoration and creating climate resilient forest ecosystems. On his off days he like to go bouldering, climbing trees and reading. He also has hopes of working in forestry abroad. ​

Biography:

​I have witnessed first-hand the effects that climate change can have on forests.  Around the turn of the century, several abnormally warm years led to the outbreak of the mountain pine beetle where I grew up in Summit County, Colorado.  Over the span of a decade, high rates of mortality transformed several thousand acres of forest, leaving behind a tinderbox of standing dead lodge-pole Pine trees.  This completely changed the landscape of the area with potential effects on longer-term ecosystem functioning.  Climate change will continue to impact and shape the forests of the Mountain West and the globe. 

I am a field-experienced and academically trained forest ecologist.  I use many approaches to study forest ecosystems, including community and ecosystem ecology, plant physiology, plot-based studies, functional ecology, and remote sensing.  My scientific motivation is to document and better understand forest (and tree) responses to global change (e.g., disturbance, warming, increasing CO2, drought).  I have a fascination with high-diversity tropical forests.  I have done research in tropical and temperate forests.   

My research focuses on understanding the ecology of forests and their future functioning as ecosystems in the Anthropocene
