Overleaf is a collaborative cloud-based LaTeX editor used for writing, editing and publishing scientific documents. It partners with a wide range of scientific publishers to provide official journal LaTeX templates, and direct submission links. That means you can collaborate online, in real time, on documents requiring very specific and specialized formatting for things like equations. Overleaf is licensed for faculty, staff, and students affiliated with the Whiting School of Engineering at JHU. Those affiliated with other divisions should contact their local IT organization to check on availability of Overleaf.
