Britta is enthusiastic about data analysis methods and is a core developer of MNE-Python, an open source analysis package for neurophysiological data.

Lucy Whalley (@lucydot)

Assistant Professor at Northumbria University (Newcastle upon Tyne, UK), using atomistic modelling to study materials for renewable energy technologies. Developing software for pre- and post-processing large-scale electronic-structure calculations and spreading the "better software, better research" message as a fellow of the Software Sustainability Institute. Happy to edit papers in the following fields: materials science, quantum chemistry, electronic structure, solid state physics, thermodynamics, RSE tooling.

Ethan White (@ethanwhite)

I am a Professor in the Department of Wildlife Ecology and Conservation at the University of Florida, where I am also a member of the UF Artificial Intelligence and Informatics Research Institute. I study data-intensive problems in ecology including ecological forecasting and combining high resolution remote sensing with computer vision models to monitor and understand forests and wildlife at large scales. We focus on real world applications through collaborations with multiple federal agencies and the development of research software in R and Python. Areas that I am particularly qualified to handle include data acquisition and management, object detection/classification in imagery, time-series modeling, species distribution modeling, ecological modeling, and software related to teaching computational skills to others.

Frauke Wiese (@fraukewiese)

Associate professor for the transition of energy systems at the Europa-Universität Flensburg. Her junior research groups focuses on pathways to climate neutral and sustainable energy systems with a foucs on sufficiency, thus an absolute reduction of energy demand. Different energy and sector models support her research for reaching sustainable energy, building, industry and transport sectors.

Mengqi Zhao (@mengqi-z)

Mengqi Zhao is an Earth Scientist at the Pacific Northwest National Laboratory. She is an expert in modeling hydrologic and water resources systems across diverse spatiotemporal scales, and her research emphasizes the broader context surrounding water, including its role in shaping the complex interactions among energy-water-land-climate systems. She is interested in using novel, integrated Multisector Dynamics (MSD) models to understand the global-national-regional impacts of climate and socioeconomic change on energy-water-land systems.
