Read Full Bio ↓ View Resume

I develop intelligent systems at the intersection of earth science, environmental consulting, and artificial intelligence.. As Founder and CEO of CalleEcology Inc. and Founder/CTO of mewmewmew Inc., I build AI-powered platforms that solve critical environmental challenges while making sophisticated science tools accessible and scalable.

My technical foundation spans deep learning, ecosystem modeling, and high-performance computing, developed through roles at NASA-GSFC, UMD-ESSIC, and Montana State University. I've published 30+ papers in top-tier journals and pioneered applications from global forest dynamics models to continental-scale ecosystem analysis using space LiDAR data. I also explore creative systems thinking through digital art and visual storytelling, applying the same innovative problem-solving approaches that drive my scientific work.

Research Themes & Contributions

Earth System & Carbon Modeling
Integrating forest demography (age/size structure) into global models and reconciling top-down/bottom-up terrestrial carbon budgets.
Land Use & Climate Teleconnections
Quantifying how historical land-use changes and global climate drivers (like ENSO) shift regional carbon and methane fluxes.
Time-Series & Signal Processing
Developing segmentation algorithms to decode complex seasonal environmental data and isolate model biases.
Remote Sensing Synthesis
Fusing multi-sensor satellite data (LiDAR, optical) to track large-scale forest regrowth and shifting vegetation baselines.
Ecohydrology & Habitat Phenology
Modeling physical environmental constraints (e.g., water availability, tidal cycles) as dynamic filters for species behavior and habitat viability.
Behavioral & Coastal Ecology
Analyzing how nutrient availability, physical constraints, and human subsidies influence animal foraging and distribution in coastal zones.
Theoretical & Evolutionary Ecology
Investigating broad conceptual frameworks like evolutionary bet-hedging and the spatial dynamics of positive species interactions.
Disciplinary Leadership & Mentorship
Advancing the field of ecology through student mentorship frameworks, career path structural analysis, and science communication.
