You are cordially invited to attend the 2026 Lake Arrowhead Conference on Mass Spectrometry! The conference will take place between Friday, January 15th and Sunday, January 17th, 2025. The meeting will focus on the latest developments in mass spectrometry in both fundamentals and applications. The flexible schedule allows plenty of time for discussions. LACMS provides an excellent opportunity for students (undergraduate and graduate), postdocs, and other junior scientists to present their research in a friendly, yet inquisitive environment, and to mingle with leading experts and peers. Poster and oral presentations by graduate and undergraduate students as well as postdoctoral researchers are most welcome. A limited number of presentations by faculty are also welcome, but the focus of this meeting is really the training of students.
