The monthly series "My Favorite Element" is part of Georgia Tech's celebration of 2019 as the International Year of the Periodic Table of Chemical Elements, #IYPT2019GT. Each month a member of the Georgia Tech community will share his/her favorite element via video.

The November edition features Johannes Leisen. He is a principal research scientist in the School of Chemistry and Biochemistry and the manager of the Georgia Tech Nuclear Magnetic Resonance (NMR) Center. His favorite element is helium. He is very familiar with the element because NMR instruments require superconducting magnets, which have to be cooled by liquid helium. 

With Leslie Gelbaum, Leisen manages the daily operation of the NMR center. This includes operation, maintenance, repair of NMR instruments; training of new users; advising on NMR experiment; and helping with data evaluation and interpretation. In particular, Leisen supports solid-state and diffusion NMR experiments, as well as NMR microimaging.

Leisen is also in charge of Georgia Tech's Magnetic Resonance Imaging core (MRI) facility, which is part of the Parker H. Petit Institute of Bioengineering and Bioscience and the Walter H. Coulter Department of Biomedical Engineering (BME). Leisen teaches the BME course "Conservation Principles in Biomedical Engineering." 

Renay San Miguel, communications officer in the College of Sciences, produced and edited the videos in this series.
