Zohm is currently at the Max Planck Institute for Physics, and an Honorary Professor at LMU Munich.<ref>{{Cite web |url=https://www.ipp.mpg.de/1084808/zohm |title=Hartmut Zohm |publisher=mpg.de |access-date=April 22, 2017}}</ref>

== Early life and career == Zohm received his doctorate in 1990 from Heidelberg University and the Max Planck Institute for Plasma Physics in Garching, Germany. His doctoral thesis "Investigation of Magnetic Modes in the ASDEX Tokamak" received the Otto Hahn Medal in 1991.{{Citation needed|date=March 2020}} He was a post-graduate student at General Atomics in San Diego, California. In 1996, he habilitated in experimental physics at the University of Augsburg and was professor for electrical engineering and plasma research at the University of Stuttgart from 1996 to 1999. He has been a scientific member of the Max Planck Institute for Plasma Physics since 1999 and heads the Tokamak scenario research area. In 2003, he became an honorary professor at LMU Munich.

With his department at the ASDEX Upgrade (and JET),<ref>{{Cite web|url=https://www.ipp.mpg.de/ippcms/de/for/bereiche/e1|title=Tokamak-Szenario-Entwicklung|website=www.ipp.mpg.de|language=de|access-date=2020-03-23}}</ref> he researches plasma states (tokamak scenarios), energy dissipation, particle control including the removal of helium ash and the control of edge instabilities (edge localized modes) for optimal operation of ITER and DEMO.<ref>{{Cite journal|last=Zohm|first=H|date=1996|title=Edge localized modes (ELMs)|journal=Plasma Physics and Controlled Fusion|volume=38|issue=2|pages=105–128|doi=10.1088/0741-3335/38/2/001|s2cid=250774421|issn=0741-3335|doi-access=free}}</ref><ref>{{Cite journal|last=Zohm|first=H.|date=1994|title=Dynamic behavior of the L-H transition|journal=Physical Review Letters|volume=72|issue=2|pages=222–225|doi=10.1103/physrevlett.72.222|pmid=10056090|bibcode=1994PhRvL..72..222Z|issn=0031-9007}}</ref><ref>{{Cite journal|last=Zohm|first=Hartmut|date=2010|title=On the Minimum Size of DEMO|journal=Fusion Science and Technology|volume=58|issue=2|pages=613–624|doi=10.13182/fst10-06|bibcode=2010FuST...58..613Z |s2cid=118759732|issn=1536-1055}}</ref><ref>{{Cite journal|last1=Zohm|first1=H|last2=Kallenbach|first2=A|last3=Bruhns|first3=H|last4=Fussmann|first4=G|last5=Klüber|first5=O|date=1990|title=Plasma Angular-Momentum Loss by MHD Mode Locking|journal=Europhysics Letters|volume=11|issue=8|pages=745–750|doi=10.1209/0295-5075/11/8/009|bibcode=1990EL.....11..745Z|issn=0295-5075|hdl=11858/00-001M-0000-0027-6544-0|s2cid=250852354|hdl-access=free}}</ref>

In 1991 his doctoral thesis ''Investigation of Magnetic Modes in the ASDEX Tokamak'' received the Otto-Hahn-Medal.

In 2014, he received the American Physical Society's John Dawson Award for Excellence in Plasma Physics Research for "''the theoretical prediction and experimental demonstration of neoclassical tearing mode stabilization by localized electron cyclotron current drive".''<ref name=":0" />

In 2016, he and Sergei Bulanov received the Hannes Alfvén Prize from the European Physical Society for "''their experimental and theoretical contributions to the development of large-scale next-step devices in high-temperature plasma physics research''".<ref name=":1" />
